摘　　要：针对单相感应电机启动电流大的特点,设计了一种带有软启动的单相感应电机调速控制系统,该系统以dsPIC30F3010芯片为控制核心,通过传感器对电机的电压、电流及转速进行采样,实现变频调速及空载时降低转速的目的。实验结果表明,该系统具有平滑启停、调速节能等特点。Considering the characteristic of large starting current of single phase induction motor, a speed control system was designed for single phase induction motor with soft start. The digital controller dsPIC3OF3010 was used to regulate motor speed and to lower speed under light - load condition by sampling voltage, current and speed. Experiment result shows that the system can realize smooth starting, speed controlling and energy saving.
