Casual Forward And Reverse Motor Control Circuit
Forward and reverse operation of motor can be obtained by interchanging any two of its three terminals.
Forward and reverse motor control circuit. And from the mccb breaker i connect the supply to both. Now if either forward or reverse circuits are latched they may be unlatched by momentarily pressing the stop pushbutton which will open either forward or reverse circuit de energizing the energized contactor and returning the seal in contact to its normal open state. In short this the complete guide of forward reverse starter wiring and installation.
The stop switch having normally closed contacts will conduct power to either forward or reverse. In the diagram i connect the incoming three phase supply l1 l2 l3 to the mccb circuit breaker molded case circuit breaker. Forward reverse motor control diagram for three phase motor for a three phase motor forward reverse control circuit.
The motor operates in the forward and reverse direction by making the coil in the relay energize and de energize. Referring to the control circuit on figure a pressing the forward push button f will energize contactor f. In the circuit both the forward reverse contactor interlocked in a way that only one contactor should be in closed condition while the other is in open condition.
Motor control forward reverse. Here i showed the forward reverse wiring diagram. Press on push button f on the forward contactor coil gets supply through phase r off push button r2 forward contactor coil on push button f phase y.
Maintaining contact f 13 14 will close to maintain contact or f continually energized even if the forward push button is release. Dc motor forward reverse control working principle. Forward reversing starter with mechanical and electrical interlocking.
The forward contactor coil energized and three phase induction motor runs in the forward direction. We use 2 magnetic contactors as forward reverse switch. However if an overload occurs the contacts in the plc program will open and the motor circuit will turn off.
