abstract
- Compact high torque/power density motors are needed for electrical vehicles in modern electric cars, this calls for effective temperature control of the electric motors. The voltage level in automotive spans a large range, usually between 96Vdc and 800Vdc, which asks for flexibility in the development of the powertrains in general, and of their electrical machines in particular. This paper’s primary objective is to evaluate the thermal analysis of a Permanent Magnet Synchronous machine at different voltage levels of the power supply.
