This paper studies the noise of a Permanent Magnet Synchronous Motor (PMSM) for electric vehicles. Through the analysis of the contribution of different electromagnetic excitations to the noise, the paper identifies key factors such as motor torque ripple and spatial zero-order electromagnetic force, as well as their contributions to the order noise in different speed ranges. Moreover, through the simulation analysis of the noise under the conditions of eccentricity and current harmonics, the changes in the order noise after considering practical factors are obtained. The Kriging method is used to create an electromagnetic surrogate model, which can quickly calculate the electromagnetic force and torque ripple based on the design parameters of the stator and rotor. On the basis of the surrogate model, the genetic algorithm is used for multi-objective optimization. The order noise obtained from the simulation is significantly reduced compared with the original scheme. The good consistency between the simulation and the experiment is verified through the noise test of the optimized prototype on the test bench.
