Common Electrical Motor Controlled Circuit (1)
Working Principle: As seen in the figure 4-111, the circuit consists of switch Q, fuse FU, ac contactor KM, start button S1, stop button S2 and thermal relay KR. When we start the circuit, we should connect the switch Q, and push the start button S1. Then KM is connected, which make KM1 and KM2 connected, and the motor M begins to work. When S1 is disconnected, KM is still connected because of KM2's effect. When we stop the circuit, we should push the stop button S2, and KM is disconnected, which make KM1 and KM2 disconnected, and M stops working.
