一种优化齿槽转矩抑制永磁同步电机振动和噪声的方法
A Way of Optimizing Cogging Torque to Reduce Vibration and Noise for Permanent Magnet Synchronous Motor
摘要
Abstract
The vibration and noise of motor could be reduced by keeping a reasonable control on cogging torque.To minimize the vibration and noise of PMSM,an optimization of four main parameters (pole-arc coefficient,eccentric distance,air-gap length and magnet thickness) that affect the cogging torque was done,combining with the finite element analysis method,to analyze the vibration and noise of PMSM.First of all,select a certain number of samples by using orthogonal experiments and fit them with SVM to get a regression equation,then,the ideal cogging torque could be obtained through the optimization of the equation.Finally,took the cogging torque into the motor model for the analysis of the vibration and noise of motor.关键词
