With no luck in finding a replacement motor and a desperate attempt to save old smokey, I am wondering if insulating varnish will possibly save this motor from shorting out. The motor last time I checked does indeed run but it smokes like St. Helens. Could this stuff help seal up the motor so it may run again?

If its smoking like you say...your problems likely within the windings...meaning the varnish you put on the outside will have no effect on whats going on inside. Certainly won't hurt anything, but likely won't help your short if that's indeed the problem. Is there any popping or sizzling? Does it run to full RPM? What all went down with this fan?

I believe it does reach full RPM, I am not sure. I did not run it for long at all. It does sizzle and pop. It seemed to do this after I took the motor apart for service. I have never had this happen before.
As for Ralph, there is a chance that oil did get on the windings but people have told me that oil wouldn't do that. The motor did this after I serviced it and put fresh oil in.

| You might want to clean the winding with spray can electrical contact cleaner. As for insulating varnish, there are two types, spray on & dunking. While spray on will only get to the outside, dunking will get a bit deeper into the coils and may help, but then again, may not. It might be worth a try, at this point it cant hurt. Some electric motor repair shops can dunk the windings for you. When I was calling around looking for varnish, one shop offered to dunk. Good luck.
