摘要
利用ANSYS软件优化了一款调速永磁同步电动机,联立RMxprt和Maxwell 2D模块,建立电动机的二维有限元模型,并进行了有限元仿真计算。研究了永磁体的极弧系数与偏心距对电动机的齿槽转矩、空载气隙磁密和气隙磁场的谐波畸变率的影响。在此基础上研究极弧系数与偏心距相结合的方法优化电动机的运行平稳性。仿真结果和样机测试结果验证了该方法的可行性,对调速永磁同步电动机的优化设计具有一定的参考意义。
An adjustable-speed permanent magnet synchronous motor is optimized by u- sing ANSYS software, the 2D finite-element model of the motor is established by RMxprt and 2D Maxwell module, and the finite-element simulation calculation is carried out. The influence of pole arc coefficient and eccentric distance of permanent magnets on cogging torque, no-load air-gap flux density and harmonic distortion rate of air-gap magnetic field motor are studied. On the basis of the combination of pole are coefficient and eccentric distance, operation stability of the motor is optimized. The simulation results and test results of model motor have verified fea- sibility of the proposed method. It has a certain reference value for optimization design of this kind of motors.
