Outline
In this paper, a permanent magnet synchronous motor for vehicles was used as the research object. According to the specific structural size parameters and performance parameters of the stator and rotor blades of the motor, a two-dimensional simulation model was established in the electromagnetic field finite element analysis software to solve the electromagnetic field and loss distribution of the motor under special operating conditions. The loss density obtained by electromagnetic field simulation was imported into the temperature field simulation software to calculate the temperature distribution reaching the steady state under the operating conditions. Through the comparison of coupled simulation and single-physics simulation, it is concluded that the hot spots distribution of the coupled simulation is more concentrated, and the thermal risk of the motor can be discovered and improved in time. The working condition temperature rise test of this motor indicates that the coupled simulation temperature rise data is basically consistent with the test data, proving correctness of the motor coupled simulation results.
