Abstract:
The new vehicles for E-mobility bring specific challenges in terms of design for manufacturing and material supply chain. Task is to reduce the volume and cost of active materials in propulsion motor technologies beyond their current state-of‐art. Potential solutions include high-speed motors and higher pole numbers with/without rare earth free typologies. Advances in fast switching power semiconductor devices have enabled high frequency operation of electrical machine drives. The benefits and challenges associated with this in aerospace and automotive applications are reviewed, looking at the techniques and design choices available to the designer to reduce high frequency loss effects and extract heat.
