Inverter 变频器

An Inverter controls the frequency of power supplied to an AC motor to control the rotation speed of the motor. … The use of an inverter to adjust the speed and acceleration of an AC motor increases the range of applications of the motor compared with a motor that operates at a constant speed.

变频器是应用变频技术与微电子技术，通过改变电机工作电源频率方式来控制交流电动机的电力控制设备。
