Capacitor calculations
(OP)
Is there any way to calculate the capacitor value of a permanent split phase motor?
The motor spec is 1700rpm 1/15hp 60Hz 1ph 1.0amp
The cap value at the moment is 10 mfd but the motor is running on a 50Hz supply and getting very hot.
I know I need to increase the cap value but don't know by what.
Any help would be much appreciated.

How many amps is the motor drawing?

RE: Capacitor calculations
A larger capacitor could drop the line current but the current going into the motor windings is the very same, the only difference is the capacitor providing the reactive power instead of the line. Provide more information.
RE: Capacitor calculations
The motor pulls 0.3 amps off load

What other information?

Is the meter a True RMS meter?

It's pulling 0.5amps not .3
The meter I used first time needs calibrating I think (or bining)
