I am looking for a replacement for a fan motor the runs off of induction from attached bus work. It is very specialized and I have not been able to find a manufacture. It was made by GE but not for years

The original motor:
MOTOR, ELECTROMAGNETIC;CANADIAN GENERAL ELECTRIC,
MFG NO # 712-903074,MINIMUM EXCITATION 500 AMPS,
MAXIMUM EXCITATION 5000 AMPS

any help would be great. see pictures

Wow. That's some motor.

If it were me, I would be looking for a fan that in not a phase induction one. Maybe just a stand alone fan (single or polyphase).

But I'll keep searching with you for a replacement.

There may be a surplus motor somewhere. You might want to check with substation or power plant contractors.
 
the speed of the fan depends on the bus work loading. not sure why they made it over complicated.
