Dynamic braking circuit control thyristor

Posted on Mar 28, 2007

Circuit shown in Figure 3-148. The circuit eliminates the need for step-down transformer, using thyristor for brake control, for small capacity asynchronous motor braking amoun

t. When shut down, the contactor KM] release, KM2 pull the brake circuit to work, triggering the thyristor V conduction (per power supply positive half cycle conduction), the motor continues to give effect pulsed DC current braking, the motor is braking status. Until the time delay relay KT break NC contact is opened, the contactor KM2 release, before the end of the braking process.
