Default lathe -- opinions wanted

Motor repair place!
Often they get the old ones... for the taking and fixing.

Sorry but split phase motors NEVER have capacitors.

Since you didn't follow my suggestion to go look up what a
split-phase motor is, allow me to elucidate:

A split-phase motor is a single phase AC induction motor
with a starting winding.

It doesn't make a difference if you put a capacitor in series
with the starting winding or not, it's still a split-phase
motor.

By convention we call the ones with a capacitor "capacitor
start", and by implication if we don't call it capacitor
start then it's resistance-start (or reactance-start, same
thing to all intents and purposes).

The alternative to a split-phase motor is a shaded-pole
motor, which does not have a starting winding.

---------------------------------------------------------------
So the question still stands.

Where do you buy a split phase motor equipped with a capacitor?


You mean besides Grainger, McMaster, Grizzly, and Harbor Freight?
