Abstract

The invention discloses a motor sequential on-off control circuit. A branch formed by connecting a normally closed contact of a second alternating current contactor with a coil of a power-on delay time relay in series is connected with the two ends of a coil of a first alternating current contactor in parallel, a coil of a power-off delay time relay is connected with the two ends of the coil of the first alternating current contactor in parallel, a normally open contact of the power-on delay time relay is sequentially connected with a normally open contact of the power-off delay time relay and a coil of the second alternating current contactor in series, a first normally open contact of the second alternating current contactor is connected with the two ends of the normally open contact of the power-on delay time relay in parallel, and a second normally open contact of the second alternating current contactor is connected between a power supply and a second motor in series. When two motors connected in a main circuit are started, the first motor and the second motor are sequentially started or stopped.

Description

technical field [0001] The invention relates to a motor sequence start-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 and stop control circuit. The invention can start and stop two motors in sequence. [0004] Technical scheme of the present invention is as follows: [0005] Motor sequential start and stop control circuit, including stop button switch, start button switch, first AC contactor, second AC contactor, power-on delay time relay, power-off delay time relay, stop button switch and start button switch in sequence , The coil of the first AC conta...
