This phenomenon is characterized by electrical discharges between the rolling elements and the bearing raceways, leading to the formation of spot welds at the contact surfaces. During operation, these spot welds repeatedly break apart, generating abrasive metal debris that accelerates wear and can result in premature bearing failure.<\/p>\n<p><!--more--><\/p>\n<p>Electrical erosion can affect bearings in various types of electric motors, including AC, DC, servo, and stepper motors, and is most observed in<br \/>\nhigh-speed motors, electric vehicle regenerative braking systems, and motors controlled by variable frequency drives (VFDs). In severe cases,<br \/>\nelectrical erosion can lead to premature motor failure, posing safety risks, increasing downtime, and resulting in significant repair and replacement costs.<\/p>\n<p><strong>Common solution<\/strong><\/p>\n<p>A common mechanical solution to prevent electrical erosion is the use of hybrid ball bearings with ceramic rolling elements. These bearings provide electrical insulation between the rotor and the housing, thereby eliminating the conductive path required for electrical discharge and subsequent erosion. However, it is important to note that hybrid ceramic ball bearings can be more expensive than standard steel bearings. For roller bearings, or for bearings designed to carry higher loads and therefore employing larger rolling elements, hybrid solutions are either significantly more costly or not commercially available.<\/p>\n<p>A more economical approach is to electrically insulate standard steel bearings. Ceramic-coated bearings, typically using aluminum-oxide coatings applied to the inner or outer ring, effectively block DC and low-frequency stray currents. Coating thicknesses in the range of approximately 100\u2013200 \u03bcm are commonly rated for 1\u20133 kV DC breakdown voltage. However, due to their capacitive behavior and limited mechanical robustness, such coatings may provide reduced protection against high-frequency electrical discharge in modern motors controlled by variable frequency drives (VFDs).<\/p>\n<p><strong>Insulating Sleeve Idea<\/strong><\/p>\n<p>To effectively protect against high-frequency electrical discharge and avoid capacitive effects, a thicker electrical insulation barrier is required.<br \/>\nPolymeric insulating sleeves, typically with thicknesses in the range of 1 to 2 mm, can be used for this purpose. The choice of polymer, however,<br \/>\nis constrained by its dimensional stability at the peak operating temperature of the application. For EV traction motors, peak temperatures typically specified by OEMs are around 150 \u00b0C. While many polymers do not melt until higher temperatures, they often exhibit a glass transition temperature below 150 \u00b0C, which compromises dimensional stability at elevated operating temperatures.<\/p>\n<p>The use of glass-fiber reinforcement can help mitigate this effect and increase temperature capability; however, the presence of glass fibers may<br \/>\nintroduce abrasive wear on metallic counter surfaces, such as aluminum housings. To address these limitations, a high-temperature polymer is required that maintains dimensional stability at elevated temperatures without the need for fiber reinforcement.<\/p>\n<p><strong>Vespel\u00ae polyimide: Balancing electrical insulation and dimensional stability<\/strong><\/p>\n<p>Vespel\u00ae S is a sintered polyimide that exhibits no observable glass transition temperature or melting point. Its exceptional high-temperature resistance allows it to be used as an insert in die-cast aluminum components. This unique property is particularly important for applications involving high mechanical loads and elevated temperatures, such as traction motors operating in critical drive modes or under malfunction conditions.<\/p>\n<p>Vespel\u00ae polyimide insulating bearing sleeves can be used to electrically insulate the rotor from the housing, thereby suppressing discharge currents. They provide a versatile and cost-effective solution for mitigating electrical corrosion in electric motor bearings and can be installed during final assembly by press-fitting standard ball bearings. A Vespel\u00ae polyimide insulating layer with a thickness between 1 and 2 mm offers robust electrical insulation by significantly increasing electrical impedance. This effectively attenuates high-frequency currents traversing the bearing, thereby reducing the risk of electrical erosion. In addition, Vespel\u00ae polyimide exhibits mechanical damping properties that may help reduce noise, vibration, and harshness (NVH) in electric motor systems.<\/p>\n<p><strong>Manufacturing Vespel\u00ae bearing Sleeve<\/strong><\/p>\n<p>Vespel\u00ae polyimide components are manufactured using a powder-based direct forming process followed by high-temperature sintering. In this process, polyimide powder is compacted at room temperature into a green part, which is then sintered to produce a dense, non-meltable polyimide component. Unlike injection-molded parts, sintered components do not exhibit structural weaknesses such as weld lines or injection points. Depending on the final tolerances required for the assembly, the sintered parts can be machined using conventional metalworking equipment, including grinding operations, enabling the production of high-precision finished components.<\/p>\n<p><strong>Assembly of Vespel\u00ae sleeve onto the bearing<\/strong><\/p>\n<p>The Vespel\u00ae sleeves can be installed by press-fitting them onto either the rotor shaft or one of the bearing rings (Figure 1). In all configurations, standard steel ball bearings can be used in combination with the Vespel\u00ae sleeve, thereby eliminating the need for costly ceramic rolling elements such as those used in hybrid bearings.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-9479\" src=\"https:\/\/cti-symposium.world\/wp-content\/uploads\/2026\/06\/artikel_Vespel.jpg\" alt=\"\" width=\"976\" height=\"381\" srcset=\"https:\/\/cti-symposium.world\/wp-content\/uploads\/2026\/06\/artikel_Vespel.jpg 976w, https:\/\/cti-symposium.world\/wp-content\/uploads\/2026\/06\/artikel_Vespel-300x117.jpg 300w, https:\/\/cti-symposium.world\/wp-content\/uploads\/2026\/06\/artikel_Vespel-768x300.jpg 768w\" sizes=\"auto, (max-width: 976px) 100vw, 976px\" \/><\/p>\n<p>Figure 1: Vespel\u00ae bearing insulation sleeves can be installed on the outer diameter (left) or on the inner diameter of the bearing (right)<br \/>\nFigure 2: Assembly of bearing has been done on a 88 mm diameter roller bearing (NU209)<\/p>\n<p><strong>Assemble Bearing Equipped with Vespel\u00ae Sleeve<\/strong><\/p>\n<p>The assembly of bearings equipped with a Vespel\u00ae sleeve was evaluated by Durkopp, a manufacturer of roller bearings. In this study, Durkopp ground the outer diameter of several test bearings to achieve press-fit conditions ranging from +5 \u03bcm clearance to 50 \u03bcm interference. During assembly (Figure 2), the press-in force was measured using a load cell.<\/p>\n<p>The maximum insertion force measured during assembly is shown in Figure 3 for various interferences.

The electrical impedance was measured by IMKT (Institut f\u00fcr Maschinenkonstruktion und Tribologie at Leibniz Universit\u00e4t Hannover). The results indicate that the electrical insulation performance of Vespel\u00ae SP-1, while slightly lower than that of hybrid bearings, remains within the same order of magnitude and is<br \/>\nsignificantly higher than that of ceramic-coated bearing solutions, even when compared with the thickest ceramic coating layer (Figure 4).<\/p>\n<p><strong>Static and Dynamic Load Testing<\/strong><\/p>\n<p>To demonstrate the mechanical resistance of the Vespel\u00ae sleeve, a test was conducted on an 88 mm-diameter roller bearing (NU209). A radial load of 10 kN, which is significant for a standard roller bearing, was applied for 24 hours at a temperature of 140 \u00b0C (Figure 5). The circularity<br \/>\nof the Vespel\u00ae sleeve outer diameter was measured before and after the test. The results indicate that the circularity increased only from 3.7 \u03bcm<br \/>\nto 5.2 \u03bcm, remaining well below the supplier\u2019s specified limit of 9 \u03bcm for the bearing. These results demonstrate the excellent dimensional stability and mechanical resistance of Vespel\u00ae components under demanding operating conditions.<\/p>\n<p>A similar test was conducted at a rotational speed of 3,000 rpm. In this case, the test was performed under a higher radial load of 25 kN, but at room temperature. The results indicate that the circularity increased only from 2.9 \u03bcm to 7.0 \u03bcm after the test, which remains below the supplier\u2019s specified limit of 9 \u03bcm.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-9482\" src=\"https:\/\/cti-symposium.world\/wp-content\/uploads\/2026\/06\/artikel_Vespel3.jpg\" alt=\"\" width=\"1290\" height=\"465\" srcset=\"https:\/\/cti-symposium.world\/wp-content\/uploads\/2026\/06\/artikel_Vespel3.jpg 1290w, https:\/\/cti-symposium.world\/wp-content\/uploads\/2026\/06\/artikel_Vespel3-300x108.jpg 300w, https:\/\/cti-symposium.world\/wp-content\/uploads\/2026\/06\/artikel_Vespel3-1024x369.jpg 1024w, https:\/\/cti-symposium.world\/wp-content\/uploads\/2026\/06\/artikel_Vespel3-768x277.jpg 768w\" sizes=\"auto, (max-width: 1290px) 100vw, 1290px\" \/><\/p>\n<p><strong>Summary<\/strong><\/p>\n<p>Electrical erosion is a major reliability concern in modern electric motors, particularly in high speed and VFD controlled applications where high frequency discharge currents accelerate bearing degradation. Conventional mitigation solutions such as hybrid ceramic bearings and ceramic coated bearings offer partial protection but are often constrained by high cost, limited availability, or reduced effectiveness under high frequency electrical stress.<\/p>\n<p>The results presented in this study demonstrate that Vespel\u00ae polyimide insulating sleeves provide an effective and economical alternative for<br \/>\nelectrically insulating standard rolling bearings. By introducing a thick polymeric insulation layer, Vespel\u00ae sleeves significantly increase electrical impedance, thereby attenuating high frequency discharge currents and reducing the risk of electrical erosion. Electrical testing confirms insulation performance comparable in magnitude to hybrid bearings and clearly superior to ceramic coated solutions.<\/p>\n<p>Mechanical testing under representative load, speed, and temperature conditions further confirms the excellent dimensional stability and mechanical resistance of Vespel\u00ae sleeves. Their compatibility with standard bearings and conventional press fit assembly processes makes this solution particularly attractive for scalable industrial and automotive applications. Overall, Vespel\u00ae insulating sleeves offer a robust, versatile, and<br \/>\ncost-effective approach to improving bearing durability in electric motor systems.<\/p>\n<p>\u00a9 2026 DuPont.

In the past, let&#8217;s say 30 to 40 years ago, much of the powertrain development was driven by emissions and fuel economy improvements, with Japan and Germany leading in part. Each region followed more or less the same path, adopting technology that led in one region and then flowed to others three to five years later. What&#8217;s changed now is that each market requires a fundamentally different mix due to a combination of local regulations and consumer behaviors. In China, over 50% of vehicles are hybrids or pure BEVs; Europe is approaching 18-19% EV share; the U.S. is stepping back, with government incentives withdrawn and EV penetration expected to remain around 7-8%. For BorgWarner, as a global company serving all major OEMs around the world, the good news is that we have a resilient portfolio capable of serving all markets, no matter the propulsion type. As an industry, we must return to a customer-first mentality rather than letting governments legislate what people will buy. I think that was a complete disaster. The OEMs know what consumers want to buy. You&#8217;re going to continue to see regionalization and differences between the markets. Long term, however, we still believe in electrification; it is the only way to truly decarbonize. But it will happen at different speeds, it is dependent on many factors like infrastructure and rare earth mineral availability, and it won\u2019t be without disruption.<\/p>\n<p><strong>In your plenary speech at the CTI symposium in Novi, you used the term \u201cmoat\u201d. What are the decisive factors in stabilizing or widening it, especially in competition with China?<\/strong><\/p>\n<p>Moat is a term Warren Buffett and others used \u2013 a reference to castle moats that slow down or stop the enemy. For our industry, it means a couple of things. First, innovation: more value at lower cost, more efficient powertrains \u2013 better fuel economy for combustion, smaller batteries for the same BEV range. Second, and this is what&#8217;s changed in the last five years: speed as a moat. China is teaching the rest of the world that you must constantly reinvent and bring better products to market faster. The companies that move at speed will win; the slower ones are stuck in the old paradigm. We see this reflected in the OEM landscape too: when I joined the industry 35 years ago, growth was driven by Ford, GM, Volkswagen, Toyota. Today, the only OEMs really growing are seven or eight Chinese companies, plus Hyundai. Hyundai is still growing and doing well. Everyone else \u2013 GM is out of Europe, Stellantis retreating from India, Ford down to 3% in Europe \u2013 is shrinking. Retreating to protect a single profit pillar is not a winning strategy, in my opinion.<\/p>\n<p><strong>How does regionalization align with the traditional concept of economies of scale through a \u201cworld product\u201d? And what are the risks of speed over scale?<\/strong><\/p>\n<p>This is a great question, because for 20 to 25 years, as global vehicle volumes grew from 50 to 90 million, scale was the name of the game. We were investing heavily in technology, developing suppliers, and building factories that needed to run efficiently. What we now see is that beyond a certain point, other factors become more important than scale \u2013 specifically speed and local accountability. That doesn&#8217;t mean abandoning scale; it means finding a new balance. Housing and mechanical parts, even factory assembly, require far less scale than before because these are readily available products, and suppliers are more regionalized. Semiconductors, on the other hand, remain a scale game \u2013 chip companies pay more attention to Tier 1s and OEMs that give them high volume. The downside of scale is loss of local agility. Large global competence centers that push technology out to regions are less effective now \u2013 they&#8217;re expensive and slow. When a region has to route<\/p>\n<p>decisions back to a distant center of competence, that&#8217;s time lost, and people far from the customer are making local market decisions without fully understanding the pressure on the ground. What we find more effective is giving regions greater authority and competence \u2013 a democratization of know-how, with regions learning from one another rather than relying on a central hub. BorgWarner has a decentralized operating model for this reason.<\/p>\n<p><strong>Would a concept of \u201csimilar but not identical\u201d components across markets work for you as a supplier?<\/strong><\/p>\n<p>Definitely. Take turbochargers: they spin at 300,000 RPM and can be dangerous if they fail. Engineered for the German market \u2013 high speeds, high temperatures, autobahn use \u2013 they&#8217;re built to be virtually indestructible. In China, the use case is mainly stop-and-go traffic with 1.5-liter engines. The load profile is fundamentally different, so you don&#8217;t need the same robustness. We&#8217;ve reengineered our turbo line for China accordingly \u2013 20% lower cost than the European or North American equivalents. Five or ten years ago, we would have carried over the European or North American product into China. And we found we were no longer competitive. We were sometimes over-engineering for markets that didn&#8217;t need it \u2013 and while we told ourselves we were gaining scale, the design simply wasn&#8217;t affordable in every market.<\/p>\n<p><strong>How can leadership culture help to handle the change?<\/strong><\/p>\n<p>Leadership has to start by accepting the uncertainty. A big part of the job is looking around the corner and anticipating the future \u2013 that has become much harder. It means thinking in scenarios rather than toward a single point, even while maintaining a true north. The second shift is toward flexibility: a resilient portfolio, a flexible supply chain, and a manufacturing footprint that can serve multiple customers on the same production line rather than running just one. Leading today is about providing clarity on facts and priorities, while helping people navigate the uncertainty. The disruption increasingly comes from outside the industry, and that&#8217;s accelerating. In China, many successful automotive players came from consumer electronics \u2013 Huawei being the obvious example. In the U.S., Apple, Google, Waymo, and Tesla have demonstrated that companies with no traditional automotive background can become highly relevant because of software competence and systems thinking. These players don&#8217;t focus on individual components \u2013 they think in terms of the experience they want to deliver to the customer.<\/p>\n<p><strong>BorgWarner has been shaped strongly by powertrain hardware. What does it mean when intelligence is shifting into software \u2013 and the SDV?<\/strong><\/p>\n<p>We&#8217;ve seen software grow in the powertrain space for a long time \u2013 ECU development, electrification driving demand for complete drive modules with integrated software. The software-defined vehicle is a parallel innovation aimed at reducing development costs and enabling over-the-air updates long after a vehicle has left the dealership. If you think of how a smartphone works, the SDV follows the same logic: new features come through software, not hardware replacement. Electrification and SDV actually accelerate each other. The hardest part of implementing SDV is doing it on a legacy platform with hundreds of distributed electronic modules. The goal is to consolidate to a zonal controller architecture. At BorgWarner, we see a future where the Powertrain controller integrates into the front-end zonal architecture. Some competitors have expanded from their ECU supplier role into zonal suppliers \u2013 we&#8217;re looking at the same path. Most OEMs currently keep Powertrain as a separate subsystem, but we expect that to change, and we want to drive it.<\/p>\n<p><strong>Where is AI most important for BorgWarner as a company?<\/strong><\/p>\n<p>We&#8217;ve used machine learning and AI in our factories for a long time. Generative AI with large language models adds value in three areas. First, product development: replacing routine engineering tasks with agents and tools \u2013 code generation, test automation. The highest benefit<\/p>\n<p>comes from automating the repetitive tasks that consume significant engineering hours, freeing time and resources up to manage more strategic work. Second, factory automation: AMRs and robots are increasingly AI-enabled, and generative AI makes it significantly easier to train them. We expect a step-function increase in automation potential in our factories. Third, personal productivity and end-to-end process improvement: using tools like Copilot or Claude for daily work, and automating manual processes such as monthly financial closes and forecasting. Generative AI is one of the biggest changes we will witness. Personally, I find it liberating \u2013 you can delegate the monotonous groundwork, the research, the routine write-ups, and focus on the work that actually creates value.<\/p>\n<p><strong>How will increasingly software-defined vehicles change buyer expectations, particularly in North America, where combustion still dominates?<\/strong><\/p>\n<p>The two trends are closely linked. SDV is easier to implement on an EV platform. As EV batteries become more affordable, adoption will grow; as EV adoption grows, users will experience more features; that experience will pull more people toward EVs in the future. It&#8217;s a reinforcing cycle. We expect SDV to reaccelerate electrification as electric vehicles become cost-competitive. Europe will play this out first; North America will follow. Buyers will demand over-the-air updates, vehicles that have more features and deepen integration with their home and mobile environment. You know, these cars are awesome. So I think these two things are converging, and it will reaccelerate electrification to some degree.<\/p>\n<p>Interview:<\/p>\n<p>Gernot Goppelt<\/p>\n\n                    <\/div>\n    <\/div>\n    <\/article><\/div>\n    <\/div>\n  <\/div>\n<\/div>\n            <\/div>\n    <div class=\"post-wrapper shadow rounded-2xl bg-white\">\n        <article class=\"post relative\" itemscope=\"itemscope\" itemtype=\"http:\/\/schema.org\/BlogPosting\" data-id=\"9465\" data-categories=\"[7,23,22,8,16]\">\n    <div class=\"post-body\" itemprop=\"articleBody\">\n                        <div class=\"article-image\">\n            <a href=\"https:\/\/cti-symposium.world\/innovation-powered-by-high-fidelity-multiphysics-modeling\/\" title=\"Innovation Powered by High-Fidelity Multiphysics Modeling\" target=\"_blank\">\n                            <img decoding=\"async\" class=\"mx-auto rounded-t-2xl\" src=\"https:\/\/cti-symposium.world\/wp-content\/uploads\/2026\/06\/cti_1-768x432.jpg\" loading=\"lazy\">\n                        <\/a>\n        <\/div>\n        <div class=\"article-content p-6 prose prose-sm max-w-none\">\n            <h2 class=\"mt-0 text-base leading-snug\"><a class=\"font-semibold\" href=\"https:\/\/cti-symposium.world\/innovation-powered-by-high-fidelity-multiphysics-modeling\/\" title=\"Innovation Powered by High-Fidelity Multiphysics Modeling\">Innovation Powered by High-Fidelity Multiphysics Modeling<\/a><\/h2>\n            <time class=\"post-date\" style=\"font-size: 12px;

Introduction<\/strong><\/p>\n<p>The development of cost effective, energy efficient and reliable Integrated Drive Modules (iDM) for electric vehicles is closely tied to optimization challenges. Addressing these challenges requires Multiphysics holistic approaches, that span magnetic, electrical, thermal, mechanical and fluid domains. Such an engineering methodology has been adopted by BorgWarner.<\/p>\n<p>Across the industry, numerical methods such as Finite Element Analysis (FEA) and Computational Fluid Dynamics (CFD) are widely used to evaluate systems involving one or more physical phenomena within multiphysics analyses. These Tools form the foundation for higher level modeling approaches such as Digital Twins, which enable full system vehicle simulations and the evaluation of electric machine control strategies under real driving conditions. Combined, these Methods provide critical metrics that support decision making and guide technology development roadmaps.<\/p>\n<p>BorgWarner PowerDrive Systems Technologies &amp; Innovation group has developed a high fidelity, multiphysics based Digital Twin to support the development and innovation of iDM. The model has been rigorously validated through comparison with 78 physical signals sourced from both CAN communication channels and external sensor data [1]. In addition, some numerical models of sub components have been developed and validated in partnership with universities.<\/p>\n<p><strong>2. Methodologies Development for Deeper Insight<\/strong><\/p>\n<p>Methods form the foundation of engineering organizations. Sustaining innovation requires continuous improvement. Our methodology development strategy is grounded in in-house technical excellence, with experts actively contributing to Centers of Expertise to share best practices, lessons learned and identify improvement opportunities. This internal capability is further reinforced through strategic partnerships with academic institutions, start-ups, and technology providers. Our Analytical Simulation Design plan [1] is formed by simulation Cards whose inputs and outputs are bound to other cards to form a structured simulation framework. It enables pinpointing methodological gaps and areas where model predictions need refinement for greater accuracy and highlights phenomena that require deeper investigation through multiphysics analysis.<\/p>\n<p>Those refinements are based on a dual approach combining advanced multiphysics modeling with high-quality experimental validation. The refinements can focus non-exhaustively on thermal, electric, magnetic, mechanical or fluid dynamics behaviors on overall iDM and its subcomponents.<\/p>\n<p>One of these approaches concerns the methodology refinement applied to electric machine stator loss assessment. Stator loss can be split into iron loss and copper loss. The loss estimation enhancement is performed in collaboration with the Division of Industrial Electrical Engineering and Automation of Lund University in Sweden. The study was carried out in multiple steps to characterize the material properties, model the electromagnetic behavior, and finally perform transient thermal analysis.<\/p>\n<p>The first step of the loss evaluation is to measure the lamination loss named iron loss and magnetic properties as magnetic hysteresis curves also known as BH curves. The experimental description can be found in [2].<\/p>\n<p>The second step involves using the magnetic properties obtained in the first step and incorporating them into 3D Finite Element (FE) model of a complete wound stator under COMSOL Multiphysics, to assess the copper loss. The simulated impedances are compared to impedances measurements, and the relative error is not higher than 5% over a range of 100 Hz to 10 kHz.<\/p>\n<p>The resulting current density with the conductor cross section can be observed on Fig. 1. The current density is not equally distributed resulting in the difference of losses within the conductors. A coupled electromagnetic thermal model was then employed to perform a transient analysis under adiabatic boundary conditions with the surrounding environment. The resulting temperature distribution after a 30 s transient event is presented in Fig. 2.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-9467\" src=\"https:\/\/cti-symposium.world\/wp-content\/uploads\/2026\/06\/Fig2.jpg\" alt=\"\" width=\"500\" height=\"589\" srcset=\"https:\/\/cti-symposium.world\/wp-content\/uploads\/2026\/06\/Fig2.jpg 500w, https:\/\/cti-symposium.world\/wp-content\/uploads\/2026\/06\/Fig2-255x300.jpg 255w\" sizes=\"auto, (max-width: 500px) 100vw, 500px\" \/><br \/>\n<small>Figure 2: Temperature distribution after 30 s transient heat up in adiabatic conditions at 200 A(peak) and 1000 Hz<\/small><\/p>\n<p>At system level, the inverter generates the current waveforms required to control the electric machine\u2019s performance and control strategies are developed accordingly to enhance overall system behavior. Using the previously detailed multiphysics approach enables a precise assessment of how those current waveforms impact electrical machine losses. This capability permits us to optimize the influence of innovative control strategies at inverter level on vehicle efficiency as demonstrated in [1], as part of our model driven innovation and optimization capability.<\/p>\n<p><strong>3. Model Driven Innovation and Optimization<\/strong><\/p>\n<p>Innovation and optimization of the iDM are supported by several key pillars. One of them is Process and Design Development. Process and design tools are evolving in parallel, allowing engineers to explore innovative geometries and structures that were previously unattainable. Such optimization has been performed for a heatsink used in a power electronincs device, resulting in complex geometry as shown on Fig.3. A cooling liquid is turbulently flowing inside the heatsink to cool two heat sources. The topology optimization has been set to minimize the temperatures of the heat sources and their temperature differences, while being below a pressure drop threshold. It defines the inner geometry. The synergy between 3D metal printing and numerical multiphysics topology optimization has become a key driver for innovative solutions.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-9468\" src=\"https:\/\/cti-symposium.world\/wp-content\/uploads\/2026\/06\/Fig3.jpg\" alt=\"\" width=\"750\" height=\"443\" srcset=\"https:\/\/cti-symposium.world\/wp-content\/uploads\/2026\/06\/Fig3.jpg 750w, https:\/\/cti-symposium.world\/wp-content\/uploads\/2026\/06\/Fig3-300x177.jpg 300w\" sizes=\"auto, (max-width: 750px) 100vw, 750px\" \/><br \/>\n<small>Figure 3: 41st iteration of 3D topology multiphysics optimization with a turbulent flow and two heat sources at the lowest surface<\/small><\/p>\n<p>A second pillar is driven by AI breakthroughs in materials development. Historically, geometry\/function and material selection have always been closely intricated in the development of components. Recent progress in artificial intelligence has significantly accelerated the growth of Computational physics, chemistry, and materials science. These approaches leverage quantum mechanics to predict the atomistic structure of materials and translate it into macroscopic physical properties. Machine\u2011learning\u2011based computational physics now enables tailoring a material\u2019s atomic structure to meet specific performance requirements [3].<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-9469\" src=\"https:\/\/cti-symposium.world\/wp-content\/uploads\/2026\/06\/Fig4.jpg\" alt=\"\" width=\"750\" height=\"304\" srcset=\"https:\/\/cti-symposium.world\/wp-content\/uploads\/2026\/06\/Fig4.jpg 750w, https:\/\/cti-symposium.world\/wp-content\/uploads\/2026\/06\/Fig4-300x122.jpg 300w\" sizes=\"auto, (max-width: 750px) 100vw, 750px\" \/><br \/>\n<small>Figure 4: Integrated Drive Module iDM 180-HF, illustrating the inverter, its liquid cooled power module and its Viper power switches.<\/small><\/p>\n<p>The third pillar is enabled by Digital Twin, which builds upon the first two approaches to optimize physical components and reinforce system\u2011level foundations. This pillar focuses on the development and evaluation of innovative control algorithms and new iDM control strategies [4]. Although the inherent complexity of the vehicle system impacts Simulation time, preliminary insights can often be obtained within only a few electrical cycles. While advanced control algorithms can be evaluated on a millisecond timescale, the full potential of Digital Twins is realized when combined with Reduced Order Models (ROMs), which significantly<br \/>\naccelerate simulation performance.<\/p>\n<p><strong>4. Use Case<\/strong><\/p>\n<p>The Digital Twin methodology makes it possible to extract high level, system wide performance indicators while still capturing the detailed behavior and interactions of individual components. Fig.4 illustrates this multiscale capability by zooming from the overall iDM architecture comprising the inverter, electric machine, and transmission, down to ist subcomponents. Within the inverter, for example, the power module is modeled at a granular level. It consists of a stacked assembly that typically includes heatsink, thermal interface material (such as a thermal pad), and the power semiconductor switch. This detailed representation ensures that local thermal electrical behavior including parasitic phenomena are accurately captured and propagated up to system level performance metrics.<\/p>\n<p>In this study, a vehicle Digital Twin embedding all multiphysics complexity into one single environment is employed. Electric machine, inverter and transmission models are interconnected and brought into a full vehicle representation. This includes detailed, non-exhaustively, thermal management, intelligent control strategies, thermal models, cooling system, lubrication.<\/p>\n<p>Based on the vehicle Digital Twin simulation over a WLTP cycle, the results presented in Fig. 5 demonstrate the benefit of combining detailed component-level analysis with a system-level approach to assess global performance indicators.<\/p>\n<p>The power switch temperatures can be accurately estimated at both granular and helicopter views. The evolution of the maximum power switch temperature over a single WLTC for three different thermal conductivities of the pad can be evaluated. The temperature profile exhibits alternating peak and cool\u2011down phases, driven by several factors such as instantaneous current demand, DC-link voltage, switching frequency, and the applied control strategies. In addition, the absolute power losses are strongly influenced by the semiconductor die Technology itself, which affects both switching and conduction losses. While many studies assume a constant coolant temperature at the heatsink inlet, vehicle thermal management has a major impact on component thermal behavior. Radiator valve actuation, front fan operation, and the overall thermal Management architecture and control strategy directly influence the inlet coolant temperature evolution. Consequently, these effects lead to different maximum temperature levels for the power electronic components, highlighting the importance of a fully coupled electro\u2011thermal\u2011system simulation approach.<\/p>\n<p><strong>5. Conclusion<\/strong><\/p>\n<p>The development of new numerical methodologies, validated through experimental investigations, enables a deeper understanding of coupled field effects, such as fluid, mechanical, thermal, electric, magnetic, and parasitic phenomena, and their impact on system behavior. By combining detailed component level multiphysics models with vehicle level driving cycles, BorgWarner\u2019s Digital Twin provides system wide performance indicators while preserving physical fidelity. This capability transforms simulation from an analysis tool into a decision making and optimization platform for architecture selection, material choices, and control strategies. The ability to assess component-level impacts at granular view while simultaneously maintaining a helicopter view at system level is a key enabler for rapid innovation and robust holistic optimization.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-9470\" src=\"https:\/\/cti-symposium.world\/wp-content\/uploads\/2026\/06\/Fig5.jpg\" alt=\"\" width=\"750\" height=\"246\" srcset=\"https:\/\/cti-symposium.world\/wp-content\/uploads\/2026\/06\/Fig5.jpg 750w, https:\/\/cti-symposium.world\/wp-content\/uploads\/2026\/06\/Fig5-300x98.jpg 300w\" sizes=\"auto, (max-width: 750px) 100vw, 750px\" \/><br \/>\n<small>Figure 5: Overview of Digital Twin capabilities from granular to helicopter view providing global performance indicators at vehicle system level.<\/small><\/p>\n<p>&nbsp;<\/p>\n<hr \/>\n<p><strong>Sources:<\/strong><br \/>\n[1] Bossi, A., Bourniche, E., Leblay, A., David, P. et al., \u201eDigital Twin, A Multiphysics Numerical Tool Chain for Next Generation Electric Drive Design,\u201c SAE Technical Paper 2025-01-8624, 2025.<br \/>\n[2] Colombo, L., Reinap, A., Fyhr, P., Alak\u00fcla, M., \u201eEnhancing Core Loss Tracking Accuracy in Stator Cores: A Comparative Assessment of Static and Dynamic Jiles-Atherton Model Formulations,\u201c IEEE Transactions on Magnetics, vol. 61, no. 8, pp. 1-12, Aug. 2025, Art no. 7300512<br \/>\n[3] Boziki, A. \u201cHPC in Physics: Enabling Simulations and Accelerating Data Processing,\u201d Presentation at SCynergy, April 2025.[3]\n[4] Nanjundaswamy, H., Deussen, J., Mayer, A. et al., \u201cA Step Beyond Two, \u201cNext Generation Multi-Level Traction Inverter with Clean Wave Technology\u201d, 46th International Vienna Motor Symposium 2025, ISBN: 978-3-9504969-4-9<\/p>\n\n                    <\/div>\n    <\/div>\n    <\/article><\/div>\n    <\/div>\n  <\/div>\n<\/div>\n            <\/div>\n\n    <\/div>\n        <div class=\"text-center mt-12\">\n        <div class=\"load-more\">\n                <button\n    class=\"\n    bg-primary hover:bg-primary-600 focus:bg-primary-600 active:bg-primary-700 \n    px-[1em] py-[0.5em] \n    text-base \n    text-white \n    font-normal \n    border-none\n    rounded-full\n    inline-flex items-center transition duration-150 ease-in-out focus:outline-none focus:ring-0 \n    \"\n    >\n    Load more&#8230;\n  <\/button>\n            <div class=\"spinner hidden\">\n                <div\n  class=\"inline-block text-primary h-8 w-8 animate-spin rounded-full border-4 border-solid border-current border-r-transparent align-[-0.125em] motion-reduce:animate-[spin_1.5s_linear_infinite]\"\n  role=\"status\">\n  <span\n    class=\"!absolute !-m-px !h-px !w-px !overflow-hidden !whitespace-nowrap !border-0 !p-0 ![clip:rect(0,0,0,0)]\"\n    >Loading&#8230;<\/span\n  >\n<\/div>\n            <\/div>\n        <\/div>\n    <\/div>\n<\/div><\/section>\n","protected":false},"excerpt":{"rendered":"<p>Impressions 2026 Start-up Voices from CTI Symposium USA What do start-ups say about their experience at CTI Symposium USA?
