摘要
文章探讨了永磁同步电动机输入电压不对称运行的动态过程.通过建立数学模型及实时仿真,获得定子电流、感应电动势、电磁转矩、角速度的实时变化曲线.结果表明,永磁同步电动机输入三相不对称电压时,其定子电流、感应电动势、电磁转矩、转速均发生振荡,这不仅使电机无法正常运行,而且可能导致电机的转子永磁体退磁.这一结果可以为改进永磁同步电动机的控制提供有力依据.
In this paper, the dynamical processes of permanent magnet synchronous motor （PMSM） under unbalanced voltages are studied. Through the simulation based on the mathematic model of PMSM, the waveforms of stator current, induced voltage, electromechanical torque, and rotor speed are acquired. As a result, some useful conclusions are obtained.
