Refurbishment of small AC motor stator....

In this video, I clean and re-varnish a stator for a vintage toilet ventilation fan motor.

[@jacobgiunta7731]

This video just saved me tons of money and now I can say to people have you ever repaired and cleaned en electric motor thanks a ton man!!

[@davida1hiwaaynet]

Glad it helped

[@MrUbiquitousTech]

Thanks for the info/demo David, that procedure is good to know!

[@davida1hiwaaynet]

Thanks, it has saved many motors that I have found.

[@fanmansteve40]

I know this was a year ago ,but I this video was very informative to me , I've never varnished a fan motor before... I know there's a certain way it has to be done in the process, but what I have is a Westinghouse motor to a 1950s box fan , and I'm planning on refurbishing it eventually , and have all the right equipment including the varnish for the procedure , but I have a question for you if you're available to answer , would fused plug have the same function on a vintage fan ?

[@davida1hiwaaynet]

Thanks and happy the motor repair video was helpful! Yes, a fused plug is a good idea it would keep the motor from catching fire if the winding were to fail.

[@fanmansteve40]

@@davida1hiwaaynet Ok, thanks friend , I appreciate it !

[@robertzack1635]

Very helpful thanks. Im kind of disappointed in people you should have more views

[@davida1hiwaaynet]

Thanks! I appreciate your comment about the views, as well. I believe that the reason these videos don't get more views is because they are a "niche" thing. There aren't that many people who would care about repairing things like this. The ones who are interested in them are usually passionate about it like I am! The folks who partake in the throw-away society are throwing away money. They will eventually suffer the consequences of this lifestyle.

[@derekobidowski5784]

I believe these motors were made by Universal Electric Company then for Nutone as the later ones had the universal electric company logo on the nameplate. then it changed to Magnetek, A.O. Smith then its currently Century these motors

[@greg1268]

Thanks for the video sir! I'm going to try this with an air compressor motor that I have torn apart and a battery charger.

[@mikegrandinette6253]

Do you have any advice on splitting a motor almost identical to this one , I can’t even get a small screwdriver between the halves?

[@davida1hiwaaynet]

It can be hard sometimes! Often, taking the bolts out and then tapping the shaft in with a brass hammer can open up a small gap. Then you can attack it with a punch tool at the gap.

[@dartsleeper1]

What attention to detail! Nice job! I wonder if you could restore an old Vornado air circulator for me. Great work!

[@brekkagreff593]

Hi there, do you need to warm the stator prior to varnish?

[@davida1hiwaaynet]

It's very good idea to warm it up. That will drive off moisture and keep from sealing in moisture. It also draws the varnish into the winding more deeply if it's hot.

[@joeynuggetz]

i cant seem to find a video that clearly shows how the lead wires are attached to the coils. I'm trying to refurbish an antique fan and I'm kinda stuck at this part. I'd like to replace the existing lead wires.

[@mikegrandinette6253]

Is there any other power supply I could use to warm a stator ,Like a low amp battery charger or something ?

[@davida1hiwaaynet]

Yes! Battery chargers work well. Some of these very small motors need more than 12V to get warm because of the high resistance. But if you enclose it in a housing to trap the heat, 12V would do it - just slower!

[@mikegrandinette6253]

I’m doing it to a 1/20 hp Redmond fan motor for my Atlas Aire window fan I hope that’s not too big, I got a video of it if you care to see it , and thanks for the advice!

[@davida1hiwaaynet]

Glad to help. Will look for your video later this evening. Now working on a car!

[@KeyboardBuster]

How about a little transformer type non-modeswitching 12v 600mA DC wall wart?

[@spatsbear]

OOPS, this is Harley, I forgot I was logged into Spats's account haha

[@pepsicolachao4537]

LOL

[@tylertakes2241]

i know you said theses windings do not show a short but have you ever saved a motor winding, with this method, on a winding that does show a short or have low resistance? Great video by the way, thanks for sharing.

[@davida1hiwaaynet]

Glad you enjoyed the video! Unfortunately, I would never recommend trying to use a winding which has signs of turn-to-turn shorts. There is a fire hazard associated with this sort of failure and it's not worth the risk. I would only use re-varnishing as a method to preserve a good winding; and never to try and "repair" a bad one. Just my way of thinking. :)

[@Torontokoshiki]

Hi there thx for the great video. What is that ge fannpage you spoke of, I searched for it but couldn't find it. Thx

[@GUE5TPA55]

Thanks Dave for muting the volume I have to wear head phone......

[@davida1hiwaaynet]

You're welcome. I know how that goes; being sensitive to sudden loud noises myself.

[@spatsbear]

GREAT demo as always!

[@davida1hiwaaynet]

Thanks, glad you found it useful!

[@coolbluelights]

huh. never knew there was such a thing as an insulation meter!

[@davida1hiwaaynet]

Yep! Used a lot in the motor, generator, and electrical power fields.

[@erlendse]

Thanks. Stuff like that can be very useful at times. Could you show the rest of the setup? I haven't seen that type of fan used for toilet fans, I have only seen axial ones used for that.

[@davida1hiwaaynet]

You're welcome! This fan and its 'brother' came from a hotel that was getting renovated. I had asked permission to save take these fans out of the trash dumpster. I found 5 of them. Two already in my car when a hotel manager came out and threatened me for climbing in the dumpster. He took the other 3 fans inside the office. I never had the housings for these blowers. In USA, this type of fan is very common. They will push air against a significant backpressure. They are used in buildings with a long air duct from the fan to the outdoors.

[@joshg678]

I believe dumpsters are considered public property and the owners can't tell you to not take items. They can take it out of the dumpster and hold it till you leave.

[@davida1hiwaaynet]

Probably true. I just didn't feel like pushing the issue. I was shocked because I had already got permission and was blindsided by this.

[@lesdmark]

May the deity of blower motors cause his fingernails to fall off and his bathroom become a noisy place.

[@davida1hiwaaynet]

May he breathe compressed taco bell poop fumes in a confined space henceforth!

[@HellaGood]

You are awesome. lol
