Forward Reverse Motor Control Diagram For 3 Phase Motor

Forward reverse motor control diagram. This post is about the controlling and wiring diagram of 3 phase motor forward reverse motor starter. In this post, you will complete learning about the forward reverse three phase motor controlling starter diagram. In the 3 phase motor forward reverse starter wiring diagram. 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 short this the complete guide of forward reverse starter wiring and installation.

Forward Reverse Motor Control Diagram for Three Phase Motor

For a three-phase motor forward reverse control circuit. We use 2 'magnetic contactors' as forward reverse switch. Here I showed the forward reverse wiring diagram. In the diagram, I connect the incoming three phase supply L1, L2, L3 to the MCCB circuit breaker (molded case circuit breaker). And from the MCCB breaker, I connect the supply to both 'magnetic contactors'.

Here the L1 is connecting to both contactors' first terminal. L2 wire connected to the both 'contactors' 2nd terminal. And L3 wire connected to both 'contactors' 3rd terminal.

But the out connection is different. Where L1 is connected to the T1 terminal and connected on the T3 terminal in 2nd magnetic contactor. The L2 is connected is both contactors in the same terminals (T2). The L3 is connected to the T3 terminal in the first contactor and in the 2nd contactor in the T1 terminal.

After 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. Here I have shown the forward reverse motor control diagram for 3 phase motor.

Now come to the controlling wiring. Here I had shown that both contactors are 220 VAC. This means that the contactors also required the neutral wire. In the above 3 phase motor forward reverse wiring diagram.
The neutral wire first goes to the thermal overload relay NC contacts and to the light indicator. From the 2nd thermal overload relay Normal close contacts the supply goes to both contactors coil contacts/terminals. And connect to both magnetic contactors A1-A1 terminals.

After 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. So if the motor trip the light indicator will glow up.

For Normally close (red/stop) push button switch the supply comes from the L3 in the red color wire. And from the NC switch, the wire goes to both NO switches (forward and reverse push button). And from here the Hold current wire goes to both magnetic contactors NO auxiliary contacts(connection points).

From 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.

The same wiring connection is done with the reverse push button switch. 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.

In the above connection, if one contactor energized then another contactor will not be energized at the same time.

  3. the only thing missng is holding contacts for maintaining....

  4. Do have a diagram of this motor control?

  5. Please I don't have the Normally close on my contactors so please where can I connect it? Thank you
