随着高铁的高速发展,异步牵引电机的振动噪声问题近年来已得到了广泛的关注和研究.本文重点探究了低阶谐波相位对异步电机电磁力波的影响.利用等效电路定性分析了考虑谐波后定转子侧电流相位的关系.对一台异步牵引电机进行电磁力分析,通过二维傅里叶分析提取电磁力波主要阶次和频率,分析了三阶主要电磁力波随谐波相位的变化.最后通过有限元仿真得到不同谐波相位下的电机振动情况,表明在空间阶次较低的情况下,电机振动和电磁力波与谐波相位的关系具有一致性.
Influence of Phase Angle of Low-order Harmonics on Vibration of the Asynchronous Traction Motor
With the rapid development of high-speed railway,the vibration and noise problem of asyn-chronous traction motor has been widely concerned and studied in recent years.This paper focused on the in-fluence of low-order harmonic phase on electromagnetic force wave of the motor.The relationship between stator and rotor current phase after harmonic was analyzed qualitatively by equivalent circuit.The electro-magnetic force of an asynchronous traction motor was analyzed.The main order and frequency of electromag-netic force wave were extracted by two-dimensional Fourier analysis.The variation of third order main elec-tromagnetic force wave with harmonic phase was analyzed.Finally,the motor vibration under different har-monic phase was obtained by finite element simulation,which showed that the relationship between motor vi-bration and electromagnetic force wave and harmonic phase is consistent under low spatial order.
