The stator coil, that is, the main winding generates a magnetic potential when it is connected to the power supply. The magnetic potential enters the air gap through the stator core, most of the magnetic potential enters the air gap through the non-shielded part of the pole, and a small part of the magnetic potential passes through the short-circuit ring-the secondary winding is in reactance The effect (or Faraday's principle of electromagnetic induction) causes a lagging magnetic potential to enter the air gap, so the two magnetic potential vectors with different phase angles in the air gap magnetic field are superimposed to form a composite magnetic potential. The resultant magnetic potential is a certain direction of rotating magnetic potential. ) The direction of rotation of the magnetic potential is always turned from the uncovered pole part of the magnetic pole to the shaded pole part, and it is required to master the method of judging the rotation direction of the motor. ) The main magnetic flux generated by the rotating magnetic potential in the magnetic circuit enters the rotor and links with the rotor winding, thereby inducing an electric potential in the short-circuited rotor winding, thereby generating a rotor current. The rotor current interacts with the rotating magnetic field in the air gap The action, according to the left-hand rule, forces the rotor conductor, causing the rotor to rotate. This is the most basic electromagnetic process that occurs in shaded pole motors.
