I have a GE Motor P/N 5KPM40KG78BX
Label info is: 1/15 HP, 115/230V, 50/60 Hz, 1 Ph, 3450/2850 RPM, Cap 5 mfd
There are 5 wires (plus ground) exiting the motor: Black – Red – White – Yellow – Green.
There is no terminal block or mounted capacitor (i.e. the capacitor is to be wired externally) .
Resistance checks show:
Black – Red = 45.9 Ohms
Yellow – Green = 20.3 Ohms
Black – White = 0.6 Ohms
Black or Red to Yellow or Green = open circuit
I need to wire this for 115V 60 Hz (including capacitor). It would be nice if I could reverse it too.
I’m guessing that the Yellow-Green pair is the main winding and the Black-Red pair the start winding. I presume the capacitor goes from White back to the main winding. Does that sound right?
What’s confusing is the dual voltage specification on the label …. I don’t see that with the wiring that I have. All I can think is that it’s been wired internally for 115V (presumably since it was bought locally – Canada attached to a small vacuum pump).
I’d appreciate any (relevant) advice.
