The motor protector circuit is composed of the power supply circuit and voltage detection control circuit, the circuit is shown as the chart. Power circuit is composed of the power transformer T, rectifier diode VD3 and filter capacitor C3. Voltage detection control circuit is composed of the potentiometer RP, diodes VD1, YD2, capacitors C1, C2, voltage regulator diode vs, resistor R, transistors V1, V2 and relays K. KM is the the original AC contactor in the motor control circuit, S1 and S2 are the stop button and start button respectively in the original motor control circuit of motor. AC 220V voltage is bucked by T, half-wave rectified by VD3 and filtered by C3 to provide DC operating power for K and its driving circuit.
