I was servicing a generic pool pump motor. It's a Century Electric (Magnetek) 1 hp, 3450 rpm, 230/115 volt, 56J frame, part #B828.
I noticed the capacitor was badly rusting. I couldn't clearly read the capacitor's label. It appears to be 20 mfd but I need to verify that value. Possiby some of you have serviced pool motors. Does 20 mfd seem to be a reasonable value for the above described motor? I've tried to locate data on it but without success. Any help greatly appreciated... I may need a new capacitor soon.
I'd go for about 20uF per horsepower, if you can't read the OE label, but I'm told by my friendly Scot neighbor "dinna gae any higher".
And I second the comments about frequent starts - Pic, "balloon capacitor", is what happened when I pushed a 3hp motor too hard. BTW the motor still just about started, [after a struggle], which reason led to the discovery of the problem.
Rod, 55uF per kW?
