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.
