The single-phase water pump in the house is out of order. After opening the power supply, the motor can not start by itself. It is necessary to turn the shaft clockwise by hand. Then, what is the problem? How can I solve it? Thank you
The capacitor is broken. Change it.
Is your starting capacitor pump is broken. Because you pump it is a single asynchronous motor..... Single-phase asynchronous motor by capacitive phase shifting function, the single-phase alternating current isolated from another 90 degree phase alternating current. The two alternating current into two groups or four groups of motor winding, forming a rotating magnetic field inside the motor rotating magnetic field induced current in the rotor, the induced current magnetic field and rotating magnetic field in the opposite direction, by rotating magnetic field push pull into the rotating state, because the rotor must be cutting magnetic lines to produce induction current, so the rotor speed must be lower than the rotating magnetic induction motor speed, so thatSo if the starting capacitor is broken, then your pump will start difficult,
