I have a vintage desk fan which runs very slowly or not at all.
It is a 4 pole induction motor 220-240 volt 50 cycle about 200 watts.
The windings have been check and are OK and the rotor and rotor bushes are fine.
Bit stuck at the moment.
However what I did try and it works so far is to put a 2μf capacitor into one of the windings, it seems to work perfectly.
Is OK to leave it running like this, I have had it running for days?
I realise that I need to fit a bleed resistor to the capacitor as I know it needs to be discharged, I use a screwdriver at the moment, any idea what value that should be?
Any help be greatly appreciated

 

You don't really need a discharge resistor on a split phase motor.
What is the reason for looking to fit one?
If it has more that one winding then it is not a shaded pole motor and must have had a cap previously?
Max.
