One can tell that the ceiling fan has a single capacitor if there is a single microfarad rating. If there are two, then it has a dual capacitor. Another way is to check the wiring terminals. If there are two sets of terminals, then it is a single capacitor. If there are three, then it is a dual capacitor.
By visual inspection of the motor or its interior, two coils marks a motor that runs at rpm rpm nominal , while 4 coils marks a rpm motor. Wiring Diagram of 3 Speed Fan Capacitor Below is a basic and simple figure of an external connection that links the ceiling fan, fan speed. Add those together to get a total of 9.
One capacitor is used for starting the motor and the other for running it. The easiest way to tell if your ceiling fan uses a single or dual capacitor is by checking the microfarad rating and the wiring terminals on the capacitor. The microfarad rating indicates the capacitor’s ability to store energy.
The capacitance of a capacitor is measured in microfarads, and it defines the energy stored in a capacitor. The capacitance must be enough to offer the required starting torque for the fan motor. The normal range of fan motor capacitors is 5 μF to 50 μF. The voltage rating of the capacitor must be according to the voltage supply of the motor.
The term “fan capacitor” refers to a capacitor used to power a ceiling fan. An electrolytic AC capacitor which non-polarized means a type of capacitor used in ceiling fans. A ceiling fan’s electrical components include a capacitor, stator, rotor, and regulator, with the capacitor serving as a critical component in the fan’s operation.
Suppose there is no capacitor connected in the ceiling fan motor circuit. This way both the starting and running windings are connected in parallel across the single phase AC supply voltage (120V in US & 230V in EU).
