So recently I pulled an Emerson 77646-AL oscillating fan from the woods in terrible condition BUT it seemed it was fixable...So later that day when I came home from the barn I put it up on my work table and got to work.70% of the bolts broke loose easily and etc.When I opened it most of the wires were torn out and missing.

However, I didn't give up and proceeded to take off the motor, fan, cage and etc and then opened the motor and found the stator rusted to the shaft.I still didn't give up and pulled them both out having to drill out the studs and found even the wires where severed that ran into the stator.I still didn't give up.

Either way.I hooked up the stator to some ac (Yeah I was that crazy) after taking the shaft out and it worked like a charm!all I did was scrape away at the rust.That was until I went to put it back in and I think the middle red "off" wire was grounded to the body and the hot grounded itself by accident and it blew the stator...I finally just looked at the stator and told myself instead of just fixing the small wire It needed to be cleaned and just rebuilt as I feared for a fire hazard or stator failure.

I've stripped it of the wiring and took plenty of pictures of the stator before I disassembled it.Now im trying to find out how to reassemble it.The wires seemed to be that the back coils where just noticeably bigger than the fronts.Uhg..I didn't keep up with those windings either and I don't feel like paying 100 dollars just to get a scrap crap one to part out.
Did I dig my own grave?Should I just call time eater and toss it or is there some sort of schematic by any chance?

(The wires as I slowly investigated on a couple coils where broken and some others where)

Welcome to the forum! 

First of all, you might want to list a clearer picture. It's hard to tell anything from your blurry picture. From your description, im also not sure what wire you disconnected. Frankly, I don't believe that simply putting the stator in backwards would do harm, unless you nicked a wire, shorting it out. 

Post a few clear pics, and I'm sure we can steer you in the right direction. 
I'm not sure what shaft you removed, but if you pulled out the hollow tube that the rotor rides on, that should not be removed. The rotor should slide off of that tube.  Also, you should not connect a stator without having a freely spinning rotor in place. Thirdly, most Emerson motors ( likely yours) have 3 headwires and need the speed coil ( in the base) connected to run the fan and also you can damage the motor if it's wired incorrectly. Yes it seems like some things might have been done that caused damage to the stator. 

Best of luck in getting it going!

Thanks for the welcome!Of course.I can put up a better one (flip phones don't do the best for cameras) But that may have been the case.

Yes you will need a replacement stator or get it rewound. You have a 2 bearing fan, called an -APG fan. It was made for the fed govt. Its one of the only larger Emerson fans to have 2 bearings. The rotor was removed correctly. 


You will also need to verify that there is a functioning switch/ Choke coil in the base as well as a functioning capacitor. Otherwise, it would be best served as a parts fan. They are not very valuable but are very good running fans when restored. We sleep every night with an APG running in our bedroom.

Yeah, I think its got a double bearing APG ill have to put one new one in the front one thats ceased or hope some wd40 will do the trick for it.Found the capacitor.its all still in one piece just missing a bolt or two and need to consider a hot wire into the capacitor and the red off wire onto the end of the switch.

Any places I could look for a new stator?   :shock:  Or possibly a pricing on how much it would cost to be rewound?

You could post on the Buy,Sell,Trade area of this forum to look for a replacement stator. If you need many parts, consider buying a parts fan and make one good one of the 2. A rewind will certainly exceed the restored value of the fan. An estimate would be $200 . Contact Rick Huckabee (member) if you're considering a rewind.

 this is at a local antique mall for $80, just to let you know that 2 bearing models are available much cheaper than a stator rewind.

Awsome!I was searching for the model number for it and thank god it seems like I found it!Now I can have a look and see if I can get me a stator and some parts.

if you want to purchase that fan I can assist with picking it up & shipping it to you-- 
I do not know the vendor --just happened across it this weekend. Lawrence
