Impressive Reverse And Forward Control Circuit
Forward reverse motor control diagram for three phase motor for a three phase motor forward reverse control circuit.
Reverse and forward control circuit. The driven machine may be damaged also. It may be necessary to wait until the motor has coasted to a. In the diagram i connect the incoming three phase supply l1 l2 l3 to the mccb circuit breaker molded case circuit.
Press on push button r on. We use 2 magnetic contactors as forward reverse switch. The reverse contactor coil gets supply through phase r off push button f2 reverse contactor coil r on push button phase y.
Maintaining contact f 13 14 will close to maintain contact or f continually energized even if the forward push button is release. Contactor f 11 12 will open to prevent contactor r to be energized. If the reverse button is pressed while the motor is run ning in the forward direction the forward control circuit is de energized and the reverse contactor is energized and held closed.
Repeated reversals of the direction of motor rotation are not recommended. This disconnects the motor from the circuit. Such reversals may cause the overload relays and starting fuses to over heat.
Here i showed the forward reverse wiring diagram.
