Old GE induction motor---just how old exactly? 1

Would anyone be able to tell me anything about this old motor? Google is not much help, as "GE induction motor Mode 96145" draws a blank.

I'm really curious as to its date--I'm suspecting 1960s, but it may be older than that. It's still in use, very intermittent service, but has not given any problems AFAIK. Drawings or schematics would be ideal, but any info would be interesting.

If you need to know, I'd contact GE directly. I've had good luck in the past with GE tracking down old equipment data via nameplate number, serial number, etc. Most other vendors, not so much, but GE seems to keep their records for a long time.

BTW, 60's vintage doesn't sound that old to me. :cool:

What's that they say though? Oh yeah~

FYI, that's a wound rotor motor. I hope you're performing maintenance on the slip rings and brushes. It was likely made in Peterborough.
 
Contacted GE. Turns out it's 1961 vintage, but they have no other information on it, like manuals or schematics or anything. That would have been sweet.

They did confirm it was a wound rotor motor, as you had said LionelHutz. (How can you tell, incidentally?)
 
Your nameplate lists the rotor voltage and rotor curent, making it either a wound rotor or a synchronous motor. The motor speed would be 900rpm for synchronous so that is ruled out leaving wound rotor as the motor type.

Also, just look at the motor. There is that hexagonal housing section between the non drive end of the stator and the end bell of the motor that wouldn't exist on a squirrel cage motor. The stator connection box is in the middle of the stator like most motors yet there is another power cable going into that extra housing on the non drive end. That housing also has an access cover that appears to be held with one screw, likely because it is frequently removed to access brushes.


 
Awesome---thanks LionelHutz!
