    • PURPOSE:To smoothly start a motor by reducing a phase control value by a thyristor during the starting operation of the motor or stopping the phase control. CONSTITUTION:A current sensor 1 detects a load start from a starting current, and a timer 2 connected with the sensor 1 receives the signal to control a trigger circuit 3 of a phase controller A. The trigger circuit 3 is controlled by minimizing the phase control time while counting for the prescribed time from the input of a detection signal from the sensor 1 or stopping the phase control. Thus, it can be smoothly started, and the rotation control or electricity-saving can be performed at normal operation time.
    • 目的:通过在电机启动操作期间通过晶闸管降低相位控制值,或者停止相位控制来平稳启动电机。 构成:电流传感器1从启动电流检测负载开始,与传感器1连接的定时器2接收控制相位控制器A的触发电路3的信号。通过使相位控制最小化来控制触发电路3 从输入来自传感器1的检测信号计数规定时间,或者停止相位控制。 因此,可以顺利地开始,并且可以在正常操作时间进行旋转控制或省电。
