Tips: How to change the rotation direction of three-phase induction motor?
As shown from the working principle of induction motor, the rotation direction of motor rotor is determined by the direction of rotor affected by the electromagnetic torque. However, the direction of electromagnetic torque depends on the direction of stator rotating magnetic field. That is to say the rotation direction of rotor is the same as the one of stator rotating magnetic field. Nevertheless, the direction of the rotating magnetic field depends on the phase sequence of three-phase power supply that has access to the three-phase windings of stator. The direction of rotating magnetic field also changes with the one of phase sequence. Therefore, simply changing the phase sequence of three-phase power supply that has access to the three-phase windings of stator can change the rotation direction of motor. This simple method is realized by connecting any two-phase power wires of three-phase power supple wires into motor.

3 Phase Induction Motor Wiring

In this video, ATO takes a 1hp (0.75kW) 220V/380V induction motor as example to explain the motor wiring. ATO first changes the wiring of induction motor from star connection to delta connection. When the induction motor is connected in delta connection, the rated voltage of motor is 220V, and when connected in star connection, the rated voltage is 380V. To demonstrate this change clearly, the induction motor is also connected to ATO 1-phase in 3-phase out VFD and it runs normally under the control of VFD.

Three-phase Motor to Single-phase (380V to 220V)

If a frequency converter is beyond your budget or availability, one way to run a three-phase motor from single-phase power is to use capacitors. In this tutorial, the step-by-step process of adapting a motor for single-phase operation is demonstrated by showing the correct capacitor sizing and wiring configuration.

Two-wire Control Wiring of VFD Forward Motor with Push Button

In this video we've guided you through how to do VFD control wiring with a self-lock push button switch to run the motor in forward direction. We've covered everything from wiring to programming and even a test run. So just watch it through and hope you'll find it informative and helpful.

Three-phase Motor Forward and Reverse Wiring and PLC Programming

To achieve forward and reverse rotation of a three-phase asynchronous motor, you only need to swap the positions of any two phase wires. (Single-phase asynchronous motors need to be wired according to the instructions to achieve forward and reverse rotation).

3-phase motor reverse connection

In this video, we have 120V/220V/240/380V/415V AC motors with power from 1hp~100hp, widely used to drive various industrial machines such as fans, pumps, machine tools.

Existing reviews of 3 hp (2.2kW) 3 phase 4 pole AC Induction Motor

Bought a 3 hp induction motor

I bought this 3 hp induction motor as a replacement for a planer. There is no problem with the installation and the four baseplate holes match mine well. Also the motor came well packed in a wooden box. All in all, a very satisfying purchase.
