Abstract

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.

Description

technical field [0001] The invention relates to a motor sequence start and reverse sequence stop control circuit. Background technique [0002] In the motor control method, especially the motor start-stop function control method, in the existing control circuit, for multiple motors, there is no corresponding start sequence or stop sequence, so in actual production The process cannot meet the corresponding process requirements. Contents of the invention [0003] In view of the above technical problems, the present invention provides a motor sequential start, reverse sequence stop control circuit. The invention adopts one power-on delay time relay and one power-off delay time relay to complete the sequential automatic start and reverse sequence automatic stop control of two motors. [0004] Technical scheme of the present invention is as follows: [0005] Motor sequential start, reverse sequence stop control circuit, including stop button switch, start button switch, powe...
