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.
