Press on push button r on. It may be necessary to wait until the motor has coasted to a. Contactor f 11 12 will open to prevent contactor r to be energized. In the diagram i connect the incoming three phase supply l1 l2 l3 to the mccb circuit breaker molded case circuit. The motor m will run reverse. We use 2 magnetic contactors as forward reverse switch. The driven machine may be damaged also. Forward reverse motor control diagram for three phase motor for a three phase motor forward reverse control circuit. Referring to the control circuit on figure a pressing the forward push button f will energize contactor f. The reverse contactor coil gets supply through phase r off push button f2 reverse contactor coil r on push button phase y.
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.
Contactor f 11 12 will open to prevent contactor r to be energized. The reverse contactor coil energized and three phase induction motor runs in the reverse direction. The driven machine may be damaged also. The reverse contactor coil gets supply through phase r off push button f2 reverse contactor coil r on push button phase y. The motor m will run reverse. Contactor f 11 12 will open to prevent contactor r to be energized.
Here i showed the forward reverse wiring diagram. The reverse contactor coil energized and three phase induction motor runs in the reverse direction. Press on push button r on. Contactor f 11 12 will open to prevent contactor r to be energized. Repeated reversals of the direction of motor rotation are not recommended. The motor m will run reverse. 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. Such reversals may cause the overload relays and starting fuses to over heat. Referring to the control circuit on figure a pressing the forward push button f will energize contactor f. In the diagram i connect the incoming three phase supply l1 l2 l3 to the mccb circuit breaker molded case circuit.
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. Such reversals may cause the overload relays and starting fuses to over heat. Press on push button r on. The driven machine may be damaged also. Forward reverse motor control diagram for three phase motor for a three phase motor forward reverse control circuit. This disconnects the motor from the circuit. The reverse contactor coil gets supply through phase r off push button f2 reverse contactor coil r on push button phase y. 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. We use 2 magnetic contactors as forward reverse switch.
