Zusammenfassung: | The invention discloses a sequential starting and reverse stopping control circuit of a motor. The circuit is that a stop button switch is connected with a negative electrode of a power supply through a starting button switch and an electrolyzing delay relay; non-delay instantaneous normally-opened contacts of the electrifying delay relay are connected in parallel to two ends of the starting button switch; coils of a power-losing delay relay are connected in parallel to two ends of a coil of the electrifying delay relay; one end of a normally-opened contact of the power-losing delay relay is connected with a positive electrode of the power supply, and while the other end of the normally-opened contact of the power-losing delay relay is connected with the negative electrode of the power supply through the coil of a first AC contactor; one end of the normally-opened contact of the electrifying delay relay is connected with the positive electrode of the power supply, and while the other end of the normally-opened contact of the electrifying delay relay is connected with the negative electrode of the power supply through the coil of a second AC contactor. According to the circuit, the electrifying delay relay and the power-losing delay relay are used for controlling two motors to be sequentially automatically started and reversely automatically stopped. |
