This can be done at the motor starter or at the motor itself. If a three-phase motor is to be driven in only one direction, and upon its initial energization it is found to be rotating opposite to what is desired, all that is needed is to interchange any two of the three line leads feeding the motor. I hope you will share this post on social media.Circuits 36 Forward/Reverse Control Circuits
Now if you have any questions and have any suggestions then you can use the below comments box. I hope the above forward reverse motor control diagram / 3 phase motor forward reverse starter wiring diagram helps you to understand this connection. In the above connection, if one contactor energized then another contactor will not be energized at the same time.ģ Pole - 4 Pole MCCB Wiring Diagrams And Installationĭigital Ammeter Wiring With Current Transformer - CT Coil The touch or starting current goes from the reverse push button and connects to the first contactor Normally close auxiliary contact/terminal and from the auxiliary contacts, the wire goes to 2nd contactor Normally open auxiliary contacts/terminal and contactor coil A2 terminal as shown in the above diagram. The same wiring connection is done with the reverse push button switch. And from here the Hold current wire goes to both magnetic contactors NO auxiliary contacts(connection points).įrom the forward push button switch, the (touch current) supply goes to 2nd contactor NC auxiliary contacts and from the auxiliary contacts, the wire goes to the first magnetic contactor NO auxiliary contacts terminal and coil A2 terminal as shown in the above forward reverse motor control diagram. And from the NC switch, the wire goes to both NO switches (forward and reverse push button). So if the motor trip the light indicator will glow up.įor Normally close (red/stop) push button switch the supply comes from the 元 in the red color wire. And connect to both magnetic contactors A1-A1 terminals.Īfter that, the L1 wire is going to the thermal overload relay NO contacts and from the 2nd thermal relay NO contacts terminal the wire goes to the Light indicator. From the 2nd thermal overload relay Normal close contacts the supply goes to both contactors coil contacts/terminals.
The neutral wire first goes to the thermal overload relay NC contacts and to the light indicator. In the above 3 phase motor forward reverse wiring diagram. This means that the contactors also required the neutral wire. Here I had shown that both contactors are 220 VAC. Here I have shown the forward reverse motor control diagram for 3 phase motor. The 元 is connected to the T3 terminal in the first contactor and in the 2nd contactor in the T1 terminal.Īfter that, the three phase supply goes to thermal overload relay and from thermal overload relay, the soppy goes to the 3 phase motor connection plate and provided to 3 phase motor. The L2 is connected is both contactors in the same terminals (T2). Where L1 is connected to the T1 terminal and connected on the T3 terminal in 2nd magnetic contactor. And 元 wire connected to both 'contactors' 3rd terminal.īut the out connection is different. L2 wire connected to the both 'contactors' 2nd terminal. Here the L1 is connecting to both contactors' first terminal. And from the MCCB breaker, I connect the supply to both 'magnetic contactors'. In the diagram, I connect the incoming three phase supply L1, L2, 元 to the MCCB circuit breaker (molded case circuit breaker). Here I showed the forward reverse wiring diagram.
We use 2 'magnetic contactors' as forward reverse switch.
In short this the complete guide of forward reverse starter wiring and installation.įorward Reverse Motor Control Diagram for Three Phase Motorįor a three-phase motor forward reverse control circuit. I showed the 3 poles MCCB circuit breaker, 2 magnetic contactors, normally open, normally close push button switch, thermal overload relay, 3 phase 4 wire system supply, 3 phase motor with connection, trip indicator light, etc. In the 3 phase motor forward reverse starter wiring diagram. In this post, you will complete learning about the forward reverse three phase motor controlling starter diagram. This post is about the controlling and wiring diagram of 3 phase motor forward reverse motor starter.
