    Tips: What is an induction motor or asynchronous motor?

    An induction motor or asynchronous motor is an AC electric motor. When the induction motor running, there is relative motion between the rotating magnetic field and rotor windings in the air gap, and the induction current in the rotor windings under the effect of electromagnetic induction produces the electromagnetic torque, so as to achieve the conversion of electrical and mechanical energy.

    The stator of the induction motor is not the rotational part of motor, and its main task is to produce a rotating magnetic field. The rotating magnetic field is not achieved by the mechanical method, but by means of that the AC in the several pairs of electromagnets makes the nature of the magnetic pole change circularly, which is equivalent to a rotating magnetic field. The rotor is a rotatable conductor, mostly showing the shape of squirrel caged. Rotor winding is divided into two types of squirrel-cage and wound.
    Under normal circumstances, the rotor speed of the induction motor is always slightly lower than the speed of the rotating magnetic field (synchronous speed), so the induction motor is also known as the asynchronous 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.
