The commercial industry is growing with each passing, and most industrial operations rely on electric motors. A three-phase electric motor is one of the most widely used electric motors due to its versatility and reliable performance. 

Do you know the induction market is projected to grow at a CAGR of 9.5% over the forecast period of 2023-2028? Well, that is because of rapid technological advancement and industrial growth. 

Usually, 3-phase electric motors rotate in the direction of the magnetic field. However, sometimes it is necessary to change the direction of three phase motor for different applications. The motor can be easily changed with proper consideration. 

So, if you are finding out how to change rotation on 3 phase electric motor, you have landed in the right place. This brief guide will discuss simple steps to change three-phase motor rotation. 

Let’s dive deep into it!

How to change the rotation on 3 phase electric motor? 4 easy steps

Understanding how to change rotation on 3 phase electric motor is essential to ensure you do not end up damaging your electric motor. For efficient and flawless operation, changing the direction of the induction motor is crucial.

Here are 4 easy steps you can follow to change the rotation on 3 phase electric motor;

Step 1: Disconnect power source

Before you are going to change the rotation of the 3-phase electric motor, disconnect the power source. Disconnecting the power source is important to ensure safety and damage to the machinery. If you attempt to change rotations without cutting the connection, it can cause electric shocks, which would damage the equipment. 

Step 2: Reverse the wires

Now, the most important step in understanding how to change rotation on 3 phase electric motor is swapping the wires. You need to reverse the connection of two power lines of the leads connected to the terminal box in order to reverse the direction.

You can change wires that connect to T1 and T3 terminals or change the T2 and T4 terminals. After changing the two phases, the rotor will start rotating in the opposite direction. 

Step 3: Test the connection

Testing is the most crucial step to check if the motor rotation has been reversed or not. There are two simple ways to test the rotation of the motor, physical inspection or meter testing. You can either inspect the physically or with a phase rotation meter.

Step 4: Develop a connection

The final step of changing motor rotation is reconnecting the motor to the power source. Make sure the connection is in place and secure without any failure. A secure connection will reduce the chances of sparks and motor malfunction. 

Does changing motor rotation affect motor functioning?
