摘要/Abstract

摘要： 电磁振动是影响电机性能的主要因素之一,针对瓦片形磁极永磁电机2p阶径向电磁力波引起的电磁振动,提出优化磁极参数的方法用以改变高阶磁密谐波相位和幅值,进一步削弱2p阶径向电磁力波幅值。根据径向磁密解析表达式,推导出2p阶径向电磁力波与磁极参数的函数关系,分析各磁极参数对气隙磁密和2p阶径向电磁力波的影响;进一步求得使2p阶径向电磁力波幅值最小化的目标函数,并用内点法得到优化的磁极结构参数,对比分析优化前后有限元计算的电磁性能和2p阶处的振动响应。结果表明,该优化设计磁极的方法可在不降低电机性能的同时,抑制2p阶径向电磁力波引起的电磁振动。

Abstract: Aiming at the electromagnetic vibration caused by the 2p-order radial electromagnetic force of tile-shaped permanent magnet motor, a method was proposed to reduce the 2p-order radial electromagnetic force. Based on the analytical expression of radial magnetic density, the functional relationship between 2p-order radial electromagnetic force and magnetic pole parameters was deduced, the influence degree of each magnetic pole parameters was analyzed, and the objective function to minimize the 2p-order radial electromagnetic force was deduced, and the optimized magnetic pole structural parameters were obtained by interior point method. The electro-magnetic performance of the motor calculated by finite element method before and after optimization and the vibration response at the 2p-order were compared and analyzed. It was proved that the optimization for magnetic pole can suppress the electromagnetic vibration caused by the double frequency radial electromagnetic force without reducing the performance of the motor.

Key words: permanent magnet synchronous motor, electromagnetic vibration, air gap fundamental wave, harmonic phase, amplitude of 2p-order radial electromagnetic force
