It is called a 'starter capacitor" and is used to provide a phase shift on the starter winding to get the motor turning in the right direction when first turned on. Once the motor is running a switch opens the starter circuit through the capacitor and starting winding, as this is no longer needed for the main motor windings to keep the motor turning.

∙ 8y agoThe supply to fan is predominantly single phase. Capacitor in auxiliary winding creates phase difference. this phase difference of 90 degrees between main and auxiliary winding makes it two phase system and thus making the fan to rotate.Depending on torque requirement you choose the value of capacitor.

Why use capacitors on fan motors?
capacitor stores charge ,so we use capacitor in fan for continuous voltage supply.
Why do you use capacitors on fan motors or blowers?
We use capacitor on fan motor or blower to create phase difference between two winding(Starting & running). This phase difference introduce starting torque on fan motor. Otherwise without capacitor the torque produced in positive Half cycle of AC supply is nullify by the torque produced in negative half cycle.
Why do we use capacitor on fan motor or blowers?
Some AC motors are designed to start running as soon as electricity is provided. Other AC motors are designed for a specific purpose and do not start on AC current. They will RUN on AC, but require a DC current to start. Here's where the capacitor comes in. It stores DC power that, when released, starts the motor turning. At this point, AC current will nicely run the motor.
What capacitors are used in ceiling fan?
A capacitor add torque to an electric motor that is designed to use them, they are called PSC or permanent split capacitor type motors. the capacitors terminals go to the Run and Start windings.
Can you by-pass a capacitor in an electric motor?
You can not by-pass the capacitor in an electric motor. Most are capacitor-start motors which require the capacitor to be operational in order to start. If the capacitor is not working then it will need to be replaced.
What are blowers?
Blowers are fan like machines that transmit a large flow of air - perhaps in a super charger on an engine.
Why do you use codenser in fan?
fan is a capacitor start capacitor run single phase induction motor. since single phase induction motors are not self starters, caused by discontinuty in stator mmf. so to iniate rotation single phase supply is splitted 90 degree apart by a capacitor to convert it to a 2 phase motor, which produces a continued synchronously revolving mmf in stator to start the motor. cool !!
Is there any capacitor in exhaust fan or not?
The type of fan motor and the fan duty has to be stated. High inertia or low inertia is taken into consideration when choosing a motor for a fan application. On a three phase fan motor, no. On certain split phase fan motors sometimes yes and sometimes no. Small single phase fractional HP fans yes.
Can turning a ceiling fan generate electricity by hand turning it?
Probably not. A ceiling fan's motor converts electricity into mechanical motion. While many electrical motors can also be run as generators ceiling fan designers most likely wouldn't include that feature in designs. Ceiling fans also have a capacitor to help generate enough torque to start a fan. Sending electricity back through a capacitor in the opposite direction is not recommended.
Real time applications of induction motors?
Domestic fans, refrigerators, blowers, electric bikes, etc........
Do all motors that use capacitors must have at least one run capacitor or a run and start capacitor true or false?
true
If we change the polarity of capacitor in ceiling fan why it starts rotating reverse direction?
by changing the polarity of capacitor of single phase ceiling fan can we change the direction of rotation from anticlockwise to clockwise
