Supercharged VE Motor??

Got a nice Victrola VE-XVI with an electric motor. The motor was broken, got it fixed, and now it has so much torque that the governor hasn't got a chance of slowing it down. Even when the governor flywheel is smashed up against the pad, it still keeps spinning faster and faster. The flywheel gets really hot quickly even though the pad is well oiled. Lost 2 flyweights the first time that happened. I don't usually work on electric motor machines, sent this one out for motor repair, and it came back supercharged. Am I doing something wrong?
Thanks! Cliff

Did they maybe replace the motor instead of repairing it?

Pretty sure it's the same motor. I think all they did was clean up the armature and replace the brushes.

Just a guess, but wrong voltage?

Maybe. 120 volts?

Do you have access to a variable power supply? I don't know what voltages may have been optional at the time, but if you could use a variac, you might be able to determine what voltage the motor was constructed for.
I wonder if the motor can be wired for different voltage sources?

Cliff, did you consult the Victor-Victrola website?

I found a discussion online about early Victrola 'universal' motors with a lot of technical jargon well over my pay grade... Seems these motors were designed to run at either 32v, 40v, or 60v DC, something about rectifiers and bridges, too. Probably the motor is repaired well, but I don't know how to hook it up. Though it runs great (and fast) on 120vac, it wasn't designed to play records with that hookup. Apparently the apparatus on the back of the cabinet needs to come into play.
Anybody have an instruction booklet for this type of machine?

The resistors should have your motor running at roughly 35 volts. It will burn out at 120v. A DC power supply is nice as it reduces the brush sparking,but I have used my machine for many years on a.c. with no trouble.

I'd love to see a couple of pictures of this, Cliff. Hopefully we can get a technical thread out of this conversation!
