Abstract
In response to the national carbon neutral strategy, the electric vehicle industry has developed rapidly in recent years, and users are increasingly concerned about the NVH performance of electric vehicles. In this paper, to reduce the electromagnetic vibration noise of the motor, an improvement measure of adding notches on the rotor surface is proposed, and the rotor notches are modelled parametrically and sensitivity analysis is carried out. The effectiveness of the optimisation solution is verified by comparing the results of the electromagnetic performance, mechanical performance, electromagnetic force and noise before and after optimisation.
