Just wanted to make a mention, the most important part about a "sleeve bearing" is the felt wick; there is a felt pad that holds and transports small amounts of oil into the shaft and sleeve bearing over time, through gradual "wicking" or creeping of oil. The oil needs to go into the felt pad, until it's slightly saturated. Without putting oil on the felt pad, the motor is going to run dry much sooner. You can see on the old 1/3 horsepower motors, they have little holes for oil, and this oil goes straight into a felt pad, and not onto the shaft directly. In shaded pole motors, there is a very large piece of felt behind the pressed in "star washer" which retains the sleeve bearing.
Good tips here👍🏻 on the bearing, I like using brake cleaner followed immediately by compressed air. I then make sure it spins freely and pack with high heat grease if it has a seal. If no seal, a heavy weight and viscosity oil. Many times these motors will have an oil passageway. In that case, I start with a very thin oil in the oil port then see if it’s going to free up. Very good video, well explained. Also, you don’t sound British🤣
Hi! I have a fan that's not working anymore. There is a MF9-20A motor inside. I believe it to be a C-frame motor (so not a shaded pole motor? or is it the same kind of motor?) but I was wondering if that same cleaning and oiling technique could be used to try and make it work again. Also, could it be possible that the motor is just broken? Is there a way to test if it's broken or not? Thanks!
Good Morning Scottie, Im not sure you would like to tackle this but i have a Maxi-Torq Permanent Split Capacitor Gearmotor, it goes on a chiropractor roller table and it just quit. No smells or hot. Model 4Z519 & motor ref is 7164-0833, It says MFD for Dayton. I did notice a little bit of gear oil seeping out & it might have gotten inside. I did replace the capacitor but that didnt fix it. I cant seem to see any way to tear into it to replace the brushes and or further testing? Thanks ahead of time for your help!
Does it hum or make any noise at all, or just nothing at all? Maybe it has a thermal fuse/normal fuse that went kaboom? Either that, or gearbox seized. Well, that's what I'd check next. That's a darn expensive motor from I just saw online!
If there is wear on the bearing it's usually the bearing at the driving shaft side because of extra weight on that side of what's being turned. It's sometimes possible to instead swap the two bearings (or each side that contains the bearings) instead of fitting a new bearing, it depends on how worn the bearing is. To move the rotor in a particular direction (clockwise or anticlockwise) initially, the shaded pole causes the otherwise balanced (symmetrical) magnetic field of the stator to be twisted (clockwise or anticlockwise).
My washing machine drum stopped agitating/spinning. I noticed a capacitor next to the motor, swapped it and voila!! 🤓 I think my roommate overloaded it with clothes and burnt out the capacitor. Every load she washes is "extra" I keep telling her not to overload. She told me to "just buy a new washer cheapo" 😤 I told her if imma buy a new one it'll be for someone I'm intimate with, let her future hubby buy one 🤣
WARNING FOR FRONT LOADING WASHING MACHINE USERS : top loading machines in the US use these motors indeed, but if you are in another country, they will use a universal motor instead in their front loading machines. so if you have a front loading machine, check first if the motor isnt just an universal one, because if it is, it needs to be repaired diffrently.
Nowadays, motors in European front-loaders are often electronically-controlled motors. The one in my LG washer is like a giant flat dinner plate. It's crazy, and very neat!
@@ScottiesTech in france atleast, all washing machines i have seen use universal motors, both of my Electrolux machines (yes, i have two diffrent ones) use a universal motor with a speed controller. also, the LG motors that look like a dinner plate are direct drive motors, the universal ones are usually found in the belt driven ones. LG is the odd one for making these motors, but they are very quiet and work great. i assume these LG direct drive motors are the same as in this video too as they look extremly similar to ceiling fan motors, and thats right... ceiling fans use the same motrs as in this video. so just before trying to repair a washing machine, all you have to do is check if it uses a universal motor, if it does, too bad, if it does not, lucky for you. universal motors are also easy to repair tho, and im pretty sure someone else made a video on how to repair them.
Those sleeve bearings wick oil from the cotton, as the bearing is made of sintered metal. Sintered metal is porous. and why they last so long in a fan. Esp. if you clean and reoil the bearing, cotton, etc. I have seen fans last decades.

OH! I did not know that. Thanks for the tip!!
Thank You . . . 1 Eye . . .
Thanks👍

Very interesting, I learned something useful thanks to your teaching style. Thanks!

Excellent overview Brother TY
😊🙏🇺🇸
Is that the same kind of motor that's in old electric clocks?

Ty, fixed my old food dehydrator.

Sounds like the right response to me!
great video
Your shirt looks good. I liked the far cry shirt too tho.

Hairdryers actually use brushed DC motors usually😂
They'd probably make good windmill generators if you'd put neodymium magnets on the rotor, right ? 🤔😕😆
