The forward and reverse rotation of the single-phase motor is determined by the power supply wiring. If the power supply wiring is incorrect, it will cause the single-phase motor to reverse. Therefore, first check whether the power supply wiring is correct. The correct power supply wiring should be to connect the live wire of the power supply to the L end in the junction box of the single-phase motor, the zero wire to the N end, and the ground wire to the PE end.

How to reverse the centrifugal switch of single-phase motor (solve the problem of reverse rotation of centrifugal switch of single-phase motor)

1. Check the power supply wiring

The forward and reverse rotation of the single-phase motor is determined by the power supply wiring. If the power supply wiring is incorrect, it will cause the single-phase motor to reverse. Therefore, first check whether the power supply wiring is correct. The correct power supply wiring should be to connect the live wire of the power supply to the L end in the junction box of the single-phase motor, the zero wire to the N end, and the ground wire to the PE end.

2. Adjust the motor running direction

If there is no problem with the power supply wiring, then the running direction of the single-phase motor needs to be adjusted. The running direction of the single-phase motor can be realized by adjusting the wiring mode of the capacitor. The specific method is to exchange the two terminals of the capacitor, so that the direction of operation of the single-phase motor can be changed.

3. Replace the centrifugal switch

If the above two methods do not solve the problem of single-phase motor reversal, then the centrifugal switch needs to be replaced. The centrifugal switch is a key component of the starting circuit in a single-phase motor. If there is a problem with the centrifugal switch, it will cause the single-phase motor to reverse. Therefore, replacing the centrifugal switch is the ultimate solution to the problem of single-phase motor reversal.

Single-phase motor centrifugal switch reversal problem is one of the common faults in single-phase motors, but by checking the power supply wiring, adjusting the direction of motor operation and replacing the centrifugal switch, this problem can be effectively solved. In actual use, the appropriate solution should be selected according to the specific situation to ensure the normal operation of the single-phase motor.
