1890s GE Antique Fan Motor & Speed Control - No 337738 - Part 1: Diagnosis

In this video, we take a first look at, and diagnose the issues of, this antique GE fan motor & speed control. This motor came in for basic diagnosis and repair. We evaluate the condition of the speed control wiring and take a look inside the motor. What we find is far from good! While the speed control wiring was an easy fix, the armature contact assembly is completely ruined.
This video serves as a basis for communication with the owner about possible the condition of the motor and what can be done going forward.

Paul, thank you for your explanation of the wires leading to the speed coil. Very interesting and a good lesson to internalize should anyone else pick up a miswired unit. I can't believe the number of fans and other items that are "repaired" in a slip-shod manner, especially considering that it doesn't take much more time to do the wiring and repair correctly.

I have a General Electric aq1 and after removing the motor from the shell the coils became loose and vibrate is there a good epoxy I can use to keep them in place?

[@ElectroRestore]

Hi Wes, It is hard for me to answer that without knowing what exactly the issue is. Usually the stator is tight in the case. I never heard of one being loose. Nor have I heard of that happening to the stator coils. Normally there are some type of shims wedged in and the entire assembly shellaced in place.

[@wessandlin8056]

I am able to wiggle the coils.

[@wessandlin8056]

Is it possible the shellac holding it in place broke with all of the pounding to get the motor out?

[@ElectroRestore]

@@wessandlin8056 yes that is possible but uncommon. Did you ohm out ther coils? If they are not open or shorted, you can put generally put some wedges in between the core and the individual coils and then spray a few coats of shelac.

[@wessandlin8056]

@@ElectroRestore what would be good to use for wedges?
