Simulation and Experimental Analysis of Electromagnetic Vibration and Noise for In-Wheel-Drive Permanent Magnetic Synchronous Electrical Motor
摘要
Abstract
Electromagnetic vibration and noise prediction method of 16 poles-24 slots In-Wheel-Drive(IWD)permanent magnetic synchronous electrical motor were analyzed,which was then validated by bench test in anechoic chamber.Firstly,anisotropic material stator core and stator system with concentrated winding is established and modal results of stator system were validated by modal impact test.Secondly,for the assembly of IWD permanent magnetic synchronous electrical motor,electromagnetic,structural and acoustic multi-physical coupled model was built.Electromagnetic noise is predicted on WOT condition.Finally,electromagnetic,structural and acoustic multi-physical coupled model of permanent magnetic electrical motor was validated by bench test results in anechoic chamber.The research achievements will contribute to other permanent magnetic synchronous electrical motor design and mechanism analysis of electromagnetic vibration and noise.关键词
