    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.

    Sorry, we don't offer this type of service.
    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.
