    1. It will run the Motor, ( Because these are Capacitor start-capacitor run motors)<br />also it improves power factor

    2. since we are using single phase supply which is not a self starting machine so inorder to initially to provide some torque by changing the supply phase shift by 90 degrees <br />

  1. Great post! Generally the capacitor is there for POWER FACTOR CORRECTION. If we provide a capacitor then phase angle will change which will produce rotating magnetic field due to which fan rotates. It is really easy to install capacitor or you can take help of experienced electricians.

  2. I think, he said &quot; phase angle will produce rotating magnetic field&quot;…. Be Careful.. &quot;he meant &quot;Rotating Magnetic Field&quot;….not only &quot;Magnetic Field&quot;.<br />

  3. I have a Minka Aire F510 ceiling fan and I am using a RCS212 hand held to control it. By using the remote instead of the wall control I lose the low speed. I was told that if I replace the capacitor in the receiver with a lower one that I could get the low speed back is this something you can help with. Thank you.

    1. Power factor as per the theory is – Resistance / Impedance (R/Z) where resistance is the value of hinderance or opposition provided to the current when d.c. voltage is applied acrross the winding and impedance is the term used in the a.c voltage for the same opposition. (impedance will take account of the hinderance provided by the inductors and capacitors also inaddition to the circuit resistance where as the resistance will take only the hinderance only on the resistive parts may be the part of resistance of the inductore / capacitor as no material is pure) Impedance varies according to the frequency of the ac. voltage but the resistance will not change as it is insensitive to the frequency variations. coming to the point of improving the power factor to unity when R/Z =1 (will not be every case as Z will be more than the R due to all inductive loads such as motors and other electrical appliance) so to nulify the inductive reactance we add capactors so that the capactive reactance is in the negative force of the inductive reactance so when in a circuit Z=R+L-C when L and C are equal then Z=R , so power factor p.f =R/Z which in turn Z= R R/R=1 so we can have total effective power be used rather wasted. so in single word p.f = efficiency of the power system , power utilized /power fed

    1. Why capacitor is connected in series in ceilling fan ? Ans:- As the Ceiiling fan has two windings one is starting winding and the other is running winding. which are in parallel connection and capacitor is connected in series with the starting winding because , as per theory it produces 90 degrees lag in voltage compared to the running winding, so that there will be difference in the phase of each winding i.e running winding current and starting winding current inturn have the respective difference in the phase of the produced magnetic field, resulting in the rotating field around the rotor of the fan motor, which help the stator to follow the magnetic feild results in fan stator to rotate.
