If the direction is reversed, change the connecting wire behind the governor, and there are hints, that is, the two power connectors with CW and CCW hints. ? Three wires of the motor, two wires of the governor and a ground wire are directly connected to the governor connector.
The wiring diagram is as follows:
Single-phase motor is not only used in production, but also closely related to people's daily life, especially with the increasing improvement of people's living standards, the consumption of single-phase motor for household appliances is increasing.
In terms of production, there are micro-pumps, refiners, threshers, shredders, woodworking machinery, medical instruments and so on. There are electric fans, hair dryers, exhaust fans, washing machines, refrigerators, etc. There are many kinds, but the power is small.

Starting principle of single-phase motor: When a single-phase sinusoidal current passes through the stator winding, the motor will generate an alternating magnetic field. The intensity and direction of this magnetic field change sinusoidally at any time, but it is fixed in spatial orientation, so it is also called alternating pulsating magnetic field. This alternating pulsating magnetic field can be decomposed into two rotating magnetic fields with the same rotating speed and opposite rotating directions.
When the motor rotates in a certain direction (such as clockwise rotation) under the action of external force, the movement of cutting magnetic lines between the rotor and the clockwise rotating magnetic field becomes smaller, while the movement of cutting magnetic lines between the rotor and the counterclockwise rotating magnetic field becomes larger. In this way, the balance is broken, the total electromagnetic torque generated by the rotor is no longer zero, and the rotor will rotate in the direction of pushing.
According to the principle of forward and reverse rotation of single-phase motor, a single motor has two sets of coils, one is the running coil (main coil) and the other is the starting coil (auxiliary coil). The starting coil of most motors is not only used after starting, but always works in the circuit. The resistance of the starting coil is greater than that of the running coil. The starting coil is connected in series with the capacitor, that is, the starting coil connected with the capacitor is connected in parallel with the running coil.
