The purpose of this paper is to discuss the thermal analysis of electric vehicle powertrains. Due to their high-power output requirements, electric vehicles' traction motors generate significant amounts of heat. Motor winding insulation deteriorates rapidly when overheated. Overheating causes permanent magnets in the rotor of interior permanent magnet motors (IPMs) to lose their magnetic properties, resulting in inefficient operation. Both ends of the stator and rotor must be cooled to maintain a constant temperature. For a motor cooling system to function effectively, it must be able to handle a wide range of temperature, humidity, and dust levels. In this paper, we present an automated meshing of windings, slots, gaps, and flow paths that allows us to accurately thermal analyse liquid-cooling temperature fields.
