Tips: Running a 3-phase motor from single phase supply

If you want to connect a 3-phase motor to a single phase power supply, then you have several solutions:

Professional: use a VFD with single phase input and convert to 3-phase output, this is generally available for low power VFD (few horsepower).
Professional: apply a specially wound transformer that also mimic a 3-phase system from a single phase power supply. Expect difficulties to source and high price.
DIY: calculate a capacitor that will be connected between the remaining phases, such to apply it a phase shift and to mimic a 3-phase system.

Running a Three-phase Motor on a Single-phase Supply with a Frequency Converter

How to run a three phase or single phase motor with ATO VFD on 120V power supply. Take a 2 hp, single phase 120V input, single phase or three phase 220V output variable frequency drive as an example. It shows you how to wire, set parameters, commissioning VFD, run motors, etc.

VFD Programming for Stable Water Pressure in Water Supply System

A three-phase motor can be regulated using a single-phase 120V to three-phase 220V VFD, and control can be managed through terminals, as demonstrated in the following video.

Variable Frequency Drive Setting

In the video, it's demonstrated that ATO VFD offers multiple methods to adjust the frequency: Not only can you use the knob on the panel, but you can also utilize the buttons for adjustments.

Basic Troubleshooting Guide for VFD

In this video, ATO will show you the vfd basic troubleshooting guide.

How Many VFD Control Methods Do You Know?

Several methods to control the frequency of VFD:

1. Switch Button control: Use the switch signal to directly control the start and stop of the VFD (the VFD start frequency is fixed), and the multi-speed control method can be used to activate the speed of each section of the VFD.

2. Analog control: Use 5V or 0~20mA to control the frequency of the VFD, and at the same time can control the start and stop of the VFD in cooperation with the switch.

3. VFD potentiometer control: The VFD has its own potentiometer input terminal, and the VFD is directly controlled by the potentiometer.

4. Modbus-RTU control: Use RS485 interface to transmit data with Modbus-RTU protocol, which can monitor VFD, modify frequency, start and stop, etc.

5. DTU wireless remote control:Combine DTU terminal and VFD for wireless transmission. (DTU output analog quantity to control VFD frequency)

Running a Single or Three Phase Motor with a VFD on 120V Power

In this video, ATO will show you how to run a 120v variable frequency drive motor.

Running a Split-phase Motor with a 120V VFD (Terminal Control)

The ATO 120V inverter in the video can run single-phase motors/split-phase motors, three-phase motors. You can run the VFD in many ways.

Practical VFD

This single-phase VFD has quite complete functions. Anyway, I am looking for a wiring diagram to hook up an external potentiometer to control motor speed.
