There are two sets of coils of the washing machine, the main coil and the starting coil, and the forward and reverse rotations are in two states. For example, the forward rotation is the coil 1 is the main coil, the coil 2 is the starting coil, and the reverse rotation is the coil 2 Coil, coil 1 is the start coil! The state change is made by theMotor For Cooker Hood Manufacturers converter (manual washing machine), or the two-way thyristor (automatic washing machine)!
Using a capacitor to achieve phase shifting, different phase sequences change the direction of the magnetic field rotation; for example, the main coil is straight through, the secondary coil is phase shifted by the capacitor, and this time is forward rotation; but the secondary coil is straight through, and the primary coil is phase shifted by the capacitor. The time is reversed.
