摘要
Abstract
The intensification of competition in the field of new energy vehicles has raised the requirements for the noise,vibration,and acoustic vibration roughness(NVH)performance of drive motors.The eccentricity of the air gap may also cause vibration and noise problems in the vehicle motor.This article takes a permanent magnet synchronous motor with a rated power of 35 kW as the research object,and uses a combination of analytical and finite element simulation methods to analyze the effects of rotor dynamic eccentricity and rotor static eccentricity on the electromagnetic force characteristics of the vehicle motor.And a finite element modal simulation model of the motor structure is established,accurately analyze the working mode of the vehicle motor.Based on acoustic simulation analysis,the influence of different degrees of dynamic eccentricity and static eccentricity on the electromagnetic noise spectrum characteristics of two key working points of vehicle motors is analyzed.Finally,the correctness of the theoretical analysis is verified through motor noise testing experiments in a semi anechoic room.关键词
