How Does Capacitor Work In Fan. How does an electric motor capacitor work. A potential or current relay takes the start capacitor out of the circuit after start-up.
Capacitors change the phase angle of the EMF. I like to answer the question of how does a capacitor work by saying that a capacitor works like a tiny rechargeable battery with very very very low capacity. Any single phase motor as used in fan consists of a stator and main winding with a rotor shaft.
Suppose there is no capacitor connected in the ceiling fan motor circuit.
The fan capacitor works is not complicated. When a capacitor is so introduced the voltage lags the current by some phase angle. For example in the 50Hz frequency conditions a 1uF capacitor capacitance of about 3180 ohms. There are several key signs to look for in a bad ceiling fan capacitor such as a burning smell or frayed wires.
