Hi there, I have been given what looks like a very useful single
phase motor. 1 1/8 inch shaft. It is capacitor start, seems to be OK,
but it is taking 9 amps running light. It is also getting warm and
does not sound "happy".

The capacitor is fine, but what is likely to be wrong, that's about 3
Hp, isn't it?

Any comments welcome. Thanks George.

I would say you have a failed winding, probably why you were given it.

If it is a true capacitor start, the fact it starts turning by itself
suggest that side is OK.

9 Amps maybe reactive current, but should sound smooth with a slow
pulsing 100Hz note. At most it should get luke warm with no load.
