Tips: Induction motor’s applications
Induction motor is an AC motor whose ratio between loaded rotate speed and the frequency connected to the grid is not constant. It varies with the size of load. The larger the load torque is, the lower the rotor speed is.
Induction motor, mainly running as an electric motor with the power range from a few watts to thousands of kilowatts, is the most widely used to provide power for a variety of mechanical equipment and household appliances. Three-phase induction motor are mostlt used to drive machine tools, small and medium steel rolling equipment, fans, pumps, light industry machinery, metallurgy and mining machinery etc.Single-phase induction motor is widely used in fans, washing machines, refrigerators, air conditioners and other household appliances. Induction motor can also be used as the generator for wind power plants and small hydro-power stations.

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.

Frequency problems of induction motor

We are planning to purchase your induction motor and your VFD as well to control the motor speed. May we know the lowest frequency at which your motor runs effectively?

ATO Responded

The lowest frequency at which our motor can operate effectively is 2-5Hz.
BTW The minimum output frequency of the VFD is 0.5Hz.
