When nonlinear loads, such as adjustablespeedmotor drives, affect a sinusoidal power source, the voltage waveform is distorted and becomes nonsinusoidal.
当加上非线性负载如调速电动机驱动器时，会影响正弦电源。电压波形畸变变成非正弦波。

Comparing with frequency converting driving system for asynchronous machine and adjustablespeed for DC motor, the driving system has a wide application foreground.
与变频异步电机驱动系统和直流电机调速系统相比，开关磁阻电机驱动系统有着广阔的应用前景。
