Finite Element Analysis of EM Field of Vehicle Drive Motor Based on Ansoft

Simplorer and Ansoft Maxwell are used to perform simulation analysis of circuit and magnetic field to show whether the Ansoft Maxwell electromagnetic simulation method is effective. The structure of permanent magnet synchronous motor is studied and the permanent magnet synchronous motor electric-magnetic field theory model and electromagnetic loss model established based on electric and magnetic field coupling theory. The simulation results are consistent with test results with an error less than 5% for all parameters. The above results prove that the electromagnetic simulation model and simulation method are effective.
