Background
Single-phase motors generally refer to small-power single-phase asynchronous motors powered by a single-phase alternating current power supply (AC 220V). Such machines typically have two-phase windings on the stator and the rotor is of the conventional squirrel cage type. The distribution of the two-phase windings over the stator and the difference in the supply conditions can lead to different starting and operating characteristics. When single-phase sinusoidal current passes through the stator winding, the motor generates an alternating magnetic field, the strength and direction of the magnetic field are changed in a sinusoidal mode along with time, but the magnetic field is fixed in a spatial direction, so that the magnetic field is also called an alternating pulsating magnetic field. The alternating pulsating magnetic field can be decomposed into two rotating magnetic fields with the same rotating speed and opposite rotating directions, when the rotor is static, the two rotating magnetic fields generate two torques with the same magnitude and opposite directions in the rotor, so that the resultant torque is zero, and the motor cannot rotate. When the motor is rotated towards a certain direction (for example, clockwise rotation) by using an external force, the motion of cutting magnetic lines of force between the rotor and the rotating magnetic field in the clockwise rotation direction is reduced; the movement of cutting magnetic lines between the rotor and the rotating magnetic field in the counterclockwise rotating direction is increased. The balance is thus broken and the total electromagnetic torque generated by the rotor will no longer be zero and the rotor will rotate in the direction of thrust.
