Would someone help me identify this motor

[paulmars]

Its a GE, but they say that this line was sold to Regal Beloit. I called Regal Beloit and they cant find it in their system. A second call a month later to GE confirmed that they did sell it to them, and then a second call to Regal Beloit, and they still cant find it in their system, but did say that some lines they bought, were discontinued and all documentation was disposed of. I could guess how to wire it up, but would rather not. If anyone is interested in helping me, i will post more info and some pics.

wow Motorwiz. Thanks. I'll check the resistance w/my dvm. This switch looks like it works as ScottyUK states, for split phase, right?

Ugly as it is, this motor is not ugly enough to be a repulsion induction motor. I haven't seen one for years, and the last one I saw was old when I was young.
I have seen more than one though and they all followed a similar construction pattern.
The rotor is wound and has an inside out commutator on one end. The commutator bars form a hole about 2 inches in diameter. The ends of the bars are extended about an inch to form a face. The brushes ride on the face of the commutator and are tapered to match the taper of the commutator segments.
On the other end of the shaft is a set of centrifugal weights. When up to speed, the linkage pushes two rods through the length of the rotor. This lifts the brushes and pushes a shorting bracelet from an insulated area into the inner part of the commutator.
They were unbelievably rugged. I was called to look at one that was overloaded and would come up to speed and then drop down until the centrifugal weights collapsed and put it back into repulsion starting mode. It would accelerate and the centrifugal mechanism would switch it back to induction mode.
A modern single phase motor that is overloaded to the pint that it cycles between start and run can be expected to fail in minutes. This old beast had been cycling between the start and run mode for several days and was none the worse for wear.

In this video, you can see the shorting bracelet moving out as the motor accelerates and moving in as the motor slows at the end. From the sound, I would say that the brush lifting gear needs service badly.
