RC reverse motor braking circuit

Circuit working principle: When the button QA is started, the motor runs, the transformer T and
the full bridge VD. One VD4 works, normally closed contact CJ,. . Open, normally open contact CJ, one, connect,
capacitor G is energized. When the motor stops, the normally open contact CJ,1 is disconnected and the normally closed contact
CJ,,. When it is turned on, the capacitor C quickly discharges to RJ. After RJ acts, it closes and energizes
the AC contactor CJ2 coil. CI2 acts momentarily to give an
instant reverse current to the motor M, causing M to stop quickly under the action of the reverse current. , which solves
the inertia problem after the motor stops. The adjusting ruler can adjust the motor braking time to prevent
excessive braking and cause the motor to reverse.
