We often talk about the number of motor poles are2level-3000r/min,4level-1500r/min,6level-1000r/minEtc., and these we call synchronous speed, but in fact, each model of three-phase asynchronous motor in actual operation, its speed is different, will be lower than the synchronous speed, today, Senli motor Xiaobian will take you to understand.
The speed difference is because,Three-phase asynchronous motorThe winding used is3Group coil difference120°In the electric Angle wiring mode, the rotor speed will be lower than the rotating magnetic field speed generated by the stator winding, because the rotor speed is different from the rotating magnetic field speed, it is called asynchronous; It can also reverse the direction of rotation, that is, replace any two firewires during normal operation, and change the direction of rotation.
When the three-phase asynchronous motor is started, the rotor is stationary, and the magnetic field generated by the stator rotation is synchronous speed. The rotor cuts the stator magnetic field to generate induced electricity, and generates induced current in the short-circuit winding. The rotor current is subjected to the electric torque of the stator magnetic field and produces rotation.
In the process of rotor rotation, when the rotor reaches the synchronous speed, the stator rotating magnetic field is relatively stationary between the rotor and the three-phase asynchronous motor, the rotor will not cut the stator magnetic field and generate induced potential and induced current, the rotor will not be affected by the stator magnetic field to produce electromagnetic torque, so the rotor will slow down.
