The principle of forward and reverse rotation of the washing machine motor

The control principle of the motor's forward and reverse rotation: there are three wires into the motor, a zero wire, and the remaining two are the control wires. Assume that they are A and B. At the motor connection of the two wires of A and B, a capacitor is connected in parallel The capacity of the Motor For Exhaust Fan Supplierscapacitor is different according to the power of the motor. The role of the capacitor is to advance the AC phase angle by 90 degrees. There are two pairs of windings in the motor. When the A wire is connected to the live wire, it generates a rotating torque on one side and rotates in the forward direction. Similarly, when the B wire is connected to the live wire, the rotating torque on the other side is generated, and the motor is reversed.
As for whether A is connected to FireWire or B is connected to FireWire, this is controlled by electronic components, there are many methods, for example, there is a circuit composed of thyristors, you can achieve this solution.
