Based on Maxwell-Fluent, this paper analyzes the electric-magnetic-thermo-flow coupling of vehicle permanent magnet synchronous motor. By establishing a three-dimensional model of the motor and cooling channels of different structures, CFD is applied to compare and analyze the effects of different flow channel types, reentry modes, reentry times and inlet and outlet locations on the flow channel pressure loss and stator temperature. The results show that when the Angle between the inlet and outlet is 180°, the number of reentry is 7, and the flow channel type is rounded axial reentry, the cooling flow channel has the best heat dissipation and pressure performance. It provides data support for the design and selection of the cooling runner of the permanent magnet synchronous oil cooled motor.
