intermittent operation circuit

In some workplaces, it is necessary for the motor to start and stop, and stop and start. This is called "intermittent operation". The picture shows the intermittent operation circuit. S in the picture is a manual switch. When S is closed, KM and 1KT are powered at the same time, the main contact of KM acts, and the motor M runs. After running for a period of time (determined by the 1KT time relay), the 1KT delay closing contact closes, connecting the relay K and the other time relay 2KT circuit, the K normally closed contact opens, KM loses power, and M stops working. After a period of time, the 2KT delayed disconnection contact opens, the relay K loses power, the normally closed contact of K closes, the KM coil receives power again, and M restarts and runs. In this way, the motor realizes intermittent operation.
