Capacitor Fan Motor 78-25 For 18inch 20inch Fan , Stand Fan
Capacitor motor is mainly composed of stator, winding, rotor and bracket module. There are two windings for single-phase capacitor motor:
one is connected directly to the power supply and the other is conneced in series with a capacitor to generate a rotating magnetic field. The capacitors cause a phase shaft between the currents flowing through windings, whose axes are spatially displaced. Maxium toque is developed when the phase shift between the two currents is 90° and the amplitude of the currents is selected such that the rotating gield becomes circular.
Characteristics:
Low noise, stable operation, long life, no electromagnetic interference.
It is flexible in stack thickness, shaft dimension, bearings and fitting dimensions.
