The rotor speed of the three-phase asynchronous motor is lower than that of the rotating magnetic field, and the rotor winding is induced by the relative motion between the magnetic field and the electromotive force and current, and the electromagnetic torque is generated by the interaction with the magnetic field to achieve energy conversion. Here is a simple understanding with Senli Motor Xiaobian.
Three-phase asynchronous motorThe prerequisite for rotation is to have a rotating magnetic field, the stator winding is used to generate a rotating magnetic field, and the voltage between the phase and the phase of the phase is different in phase120The three windings in the stator are also different in spatial orientation120In this way, when a three-phase power supply is passed into the stator winding, the stator winding will generate a rotating magnetic field.
The rotating magnetic field rotates once in space for each period of current change, that is, the rotation speed of the rotating magnetic field is synchronized with the change of current. The rotation speed of the rotating magnetic field is:n=60f/PShizhongfIs the power supply frequency,PIs the number of magnetic poles of the magnetic field,nThe unit is: revolutions per minute.
