This paper presents a comprehensive examination of an integrated drive module developed for electric vehicles, emphasizing the critical issue of effectively managing heat dissipation generated by the traction motor. The compact dimensions, weight restrictions, and high-power demands of the motor necessitate careful consideration of thermal management strategies. Excessive heat can cause deterioration of the motor winding insulation and rotor magnets, leading to suboptimal performance. To tackle this challenge, cooling mechanisms are essential for both the inner rotor and outer stator components. An efficient motor cooling system must be capable of accommodating varying temperature ranges, humidity levels, and dust conditions. To analyze the thermal performance of the WEG jacket cooling design, this study employs advanced automated meshing techniques in drivetrain simulations. By investigating these aspects, valuable insights can be gained for the advancement of electric vehicle drive modules.
