Performance and efficiency are top priorities when designing motors for electric powertrains. The electric motor development for the automotive industry faces increasing complexity regarding requirements of maximum power density and changing operating loads.
In order to meet the opposing development goals of efficiency and performance, the components of the electric motor must be designed in such a way that they can be operated at overload for a limited period of time. A deep understanding of the thermal behavior of all motor components is required to prevent failure due to overheating.
