When the single-phase asynchronous motor starts, it is a "phase" process. Different from the three-phase asynchronous motor, the single-phase has no phase difference and cannot generate a rotating magnetic field. The function of adding a capacitor to it is to make the current of the starting winding of the motor ahead of the running winding in time and space90An electrician's Angle, forming a phase difference.

       Single-phase asynchronous motor is divided into starting capacitor and running capacitor, but the application of the two is different; The starting capacitor is to make the starting coil of the single-phase motor energized when starting and cut off after starting; The running capacitance is to allow the motor to compensate for the capacitance during operation, so the starting capacitance can not be less, and the running capacitance can not be used.

       But no matter what kind of capacitor, inSingle-phase induction machineIt has a starting effect at the beginning of starting. But when the motor reaches the rated speed75%When around, the starting capacitor is automatically disconnected by the centrifugal switch, and the running capacitor continues to work with the motor.

       For general motors, its capacitance is adjustable, generally only a fewUF. For asynchronous motors, capacitors are run, mostly in20UFThe following.
