The variable frequency AC controller mounts directly on the ACmotor.
变频空调控制器直接安装在交流电机。

Because the AC asynchronous motor 'synchronous speed is determined by the frequency, we can control the AC asynchronous motor' speed by changing the supply power's frequency.
交流变频调速系统是利用异步交流电动机的同步转速随频率变化的特性，通过改变电机的供电频率而进行调速。
