PWM控制变阻调速绞车

Controlling Variable-Resistance Timing Winch by PWM(Pulse Width Modulation) Equipment

分析了PWM的调整方式,利用绕线式电机和串电阻调速的原理,提出了一种结构简单、功率强的变阻调速绞车。

PWM mode was analyzed, and a kind of variable-resistance Timing Winch being of simple structure and large power supply was put forward by using wire-wound motor and series resistance timing principle.
