As shown in the figure, the circuit diagram of the self-locking control circuit of the three-phase asynchronous motor is mainly composed of the push button switch SB (starting and stopping motor), the AC contactor KM (used to turn on and off the motor, and the voltage loss and undervoltage protection). (etc.), thermal relay (used as overload protection of the motor) and so on. The main circuit of the self-locking control circuit of the three-phase asynchronous motor is substantially the same as the main circuit of the jog control, but a stop button SB1 is connected in series in the control circuit, and the contactor KM is connected at both ends of the start button SB2. A pair of normally open auxiliary contacts. The contactor self-locking forward rotation control circuit not only enables the motor to run continuously, but also has an important feature that it has undervoltage and pressure loss (or zero pressure) protection.
