Abstract:

With the growing demand for Battery-driven Electric Vehicles (BEV) to reduce the CO2 footprint and GHG emissions from the transportation sector, high-voltage batteries and wide bandgap converters (silicon carbide/gallium nitride) are critical research areas to enable more efficient BEVs with reduced charging time. The automotive motors are squeezed into small sizes for increasing torque and power supported by advanced cooling solutions. The direct cooling system is adopted more and more in the Electric Drive Unit of the propulsion system where the transmission fluid is shared with the coolant of the electrical machine.
High-voltage supply systems, wide bandgap converters, and direct oil cooling impose high stresses on the insulation system. The durability of the high-voltage oil-compatible insulation system is required to ensure the lifetime and safe operation of the propulsion system. In this webinar, an insulation system is proposed and verified using an innovative test setup representing an 800 V+ PWM supply electrical machine.

Presenters’ bio:

Dr.-Ing. Shafigh Nategh (Senior Member, IEEE) was born in 1984. He received the Ph.D. degree in electric power engineering from KTH Royal Institute of Technology, Stockholm, Sweden, in 2013. He was a Visiting Scholar with the University of Illinois at Urbana-Champaign, Urbana, IL, USA, from 2012 to 2013. From 2013 to 2015, he was a Lead Designer of PM machines for marine segment with the Rolls-Royce Group, Trondheim, Norway. He continued his career as a Designer of traction motors for railway applications with Bombardier Transportation, Västerås, Sweden, from 2015 to 2018. During this period, he was also a guest researcher at KTH Royal Institute of Technology, Stockholm, Sweden. Shafigh was an R&D Senior Engineer with E-mobility Department, ABB AB, Västerås, Sweden, in 2018–2020, and Principal Engineer with Volvo Cars, Göteborg, Sweden, in 2020-2022. In parallel to his industrial roles, Shafigh held a position as Adjunct Associate Professor at Chalmers University of Technology. He has also been Senior Principal Engineer and also Manager of the Electric Drive Unit with Polestar, Göteborg, Sweden. Since August 2023, he is Founder and CEO of SEDRIVE, a start-up company located in Göteborg, Sweden, which its mission is contribution in the development of environmentally friendly, efficient and cost-effective electric drive units. Shafigh after serving as secretary of IEEE IES Electrical Machines Technical Committee, 2021-2022, is currently a Vice-chair of IEEE IES Electrical Machines Technical Committee. He serves also as Associate Editor of IEEE Transaction on Industrial Electronics, and technical Chair/Co-chair of several electrical machine conferences in Europe and North America including ICEM, IECON, IEMDC, ONCON and ISIE. Shafigh has been also appointed as the Industry Liaison of IEEE IES Electrical Machines. His research interests include different aspects of propulsion system design in e-mobility, marine, aerospace and railway applications with focus on electric drive units.

James Bonnett (E-mobility Program Leader Transport, Victrex plc, UK) holds BSc & MSc from the University of Leeds in Mechanical Engineering and Manufacturing Futures and has worked in the fields of composites and high-performance polymers since 2003, holding a range of Commercial, Technical and Research roles as a business and product development manager. He has been with Victrex since 2013 as a Market Technology Manager within the electrified vehicle powertrains focusing on electric machines. He has been leading the R&D activities in this area for different PAEK product forms, developing technical support data, and commercial business cases, managing validation activities, and filing patents in this focus segment for Victrex. Since 2020, he has been taking care of commercial activities to deliver Victrex polymer adoption in the key application areas of e-machine magnet wire insulation and slot liner films and supporting the market segment assessment work in future e-mobility applications globally.
