Optimization of Interior Permanent Magnet Motor on Electric Vehicles to Reduce Vibration Caused by the Radial Force
Keywords:
Interior permanent magnet motor, radial force optimization, stator structural optimization and vibration behaviorAbstract
The vibration and noise level of a driven motor on electric vehicles has a great influence on the overall comfort of the whole vehicle. In this paper, the main vibrational harmonic waves with high amplitudes of Interior Permanent Magnet (IPM) motor were investigated via an experiment. In order to lower the amplitudes of these harmonic waves, the paper carries out the optimization of radial force of the IPM motor based on the parameter sensitivity analysis and also implemented the structural optimization, according to the dynamic response of the stator. The final dynamic simulation of the optimized model excited by the optimized radial force, show that the optimization results in a better performance of the vibration behaviors. This study could provide some guidelines for the optimal design of the interior permanent magnet motor to reduce vibration.
