JZT1 type slip motor thyristor speed regulating circuit

Slip motor is an AC electromagnetic speed-regulated asynchronous motor, which is an AC stepless speed-regulated motor. It has the characteristics of high mechanical properties
, high hardness, simple structure, reliable operation and wide speed range.
    The slip motor is mainly composed of three parts: a three-phase asynchronous motor, an electromagnetic slip clutch and an adjustment control device
. The JZT1 slip motor thyristor control circuit is shown in Figure 3-182. The main circuit (supplying the excitation winding) adopts a single
-phase half-controlled rectifier circuit (composed of thyristor V, etc.). The trigger circuit is a transistor trigger, which is composed of a transistor VT], a capacitor
C2, a resistor Rs, a pulse transformer TM, etc. The circuit is equipped with speed measurement negative feedback. Adjusting the potentiometer RP2 can change the feedback
amount; adjusting the master potentiometer RPi can change the speed of the slip motor .
