The main circuit consists of intelligent power module (IPM), TM320F240 is used as the control center of firepower-control servo system with higher precision.
As the existing great power consumption of empty-load or light-load, the bipolar PWM control can be applied only in small or middle powerservocontrol systems.
在轻载或空载时由于存在大的功率损耗，双极性PWM控制只能被应用于中、小功率伺服控制系统。
