I have an 6’ tall antique drill press run by a Century motor. Single phase, patented in 1899-1903. I believe it needs new brushes. There is no one local that want to touch mine either. I will attempt the rebuild and brush installation on my own. Thanks for the confidence builder.
If you search for century motor on RUclips there are a couple of videos on the older induction run repulsion motors - if that is what you have. They work very similar to this one.
Congratulations on fixing that motor man, Nice video where you show everything. Everybody said this motor was dead and you made it alive again, Respect man!
I like your appreciation of the old prior technology. It's interesting to see how we arrived at the technology we have today. I really loved the dramatic music. You look like you know your stuff. Nice video!!!
I'm so glad I found this video, I just found this exact motor out in a field! Despite sitting outside for likely a couple decades, it still turns smoothly! Just took it apart and gave it a look over, it's dirty as all get out, but I figure it'd be fun to try to get it running again. Looks like I've got myself a project! Awesome job!
Kudos on using a wood block to hammer on cast. A few years ago I watched a RUclipsr beat a Diamond T truck transmission cover with a big hammer. He broke some bolt tabs off but got it apart.
1:14 hold for just one second. It is safe to clean windings with solvent? Can I do it with WD-40? I thought the solvent would damage the enamel on the copper winding wires.
I have one of these on my workbench right now - it works but is filthy and this video has given me the confidence to open it up and clean it for my restored drill press. Thanks.,
I’ve worked on these mostly old church organ blower motors, but some of farm machinery too. When they are cleaned up and running right they are magnificent. I just love the way they snap to a sweet purr.
They still made repulsion motors into the 50's. Capacitor motors were around in at least the 1920's. It wasn't really a replacement with newer tech. Repulsion motors can be started under load like a type of Capacitor start motor BUT don't have the high inrush current draw. I read this on a Century motor spec sheet from the 40's.
Technically it is not a brush motor either - there is no line voltage fed into the brushes. As far as scrapping "old crap" there is more qualiy, durability, ruggedness, and longevity built into a lot of that old stuff versus newer stuff.
Hey Dave, great video! I am trying to rebuild my motor too, and are wondering what you used to clean everything and how you changed the wiring. I am not experienced with rebuilding these but still want to try and tackle this myself. Any info you can share would be much appreciated. Thanks!
So cool! Took me a while to figure out what I was looking at but in time and with some help, it all came together. I have a few monster motors lined up to restore, make sure you sub, they’ll be happening soon
Thanks for the video, nice rebuild. I’m about to restore a similar 1950, 1hp. There’s a clicking I’m hearing in my motor. I’m only guessing it’s the centrifugal switch. At 1:45 of your video yours appears to have tension to it. At 3:45 it does not and is how mine is always with no tension. Normal? I assume not.
I have a VERY old marathon 1/6 h.p motor. What type of “thrust washers/spacers” should I use to replace the old brittle ones, they don’t even feel metal anymore, they crack like plastic. But the machine is 80 years old lol. Tia
We have these on our Flume and Multifix motors we rebuilt the two Flumes recently, we just call them Repulsion motors. Does yours have a speed controller or are you going to just set it and run it at an adjusted set speed? If adjustable did not see well enough during the filming. These motors are incredible and can do a lot of controlled speed work so of course we are happy to see you save this guy. We love your motor because we have so many vintage motors for our projects here to be date period correct during rebuilds for our shop. Thank you for sharing a piece of American history. Lance & Patrick.
Any help with the wiring? I just bought a similar century dual voltage, but the leads are cut and very oily, don’t even know where to start to run it at 120 V
Awesome retro. Question, I have a vintage GE motor. Need to replace start condenser, is there a positive and neg wire attachment? If so, how to I tell which connection is the positive side? Thx
dave i have a 1/4 horse attic fan motor 1750 rpm 1950 s old .its a century brushless . i used a wire wheel to clean the inner windings then i cleaned the center shaft rotor with a wire wheel i exposed some of the windings to a bright copper color on the inner windings .. i replaced the heat stat and capacitor.... the motor turns on gets hot charters and shuts off ? any suggestions? thanks Reply
Hey Dave. Any chance you’re considering making a more in-depth restoration video of a vintage electric motor? Oh let’s say for example, an early 40’s Craftsman type? Covering rewiring, finding and replacement of flat capacitors, bearings, etc. Asking for a friend........... who’s probably restoring a ‘41 Craftsman wood lathe and ‘41 Craftsman Bandsaw and hoping to stay with the Craftsman vibe by including motors that were originally sold with these models. He may or may not have taken one apart initially and had the old wires disconnect before taking pictures of where everything went. Not that he’s an idiot or anything.......... Thanks bud. Great remodel by the way. Take care. Matt
Hi Dave. Love the old Century motors. Thanks for sharing yours here! I have a 94 year old Century repulsion-start motor; in its original application. It's part of a Frigidaire refrigerator. Belt-driven sulphur dioxide compressor system. The older Century motor seems to be almost identical to yours, mechanically. The housing design is a little different, though. Mine has ring-oiled journal bearings. The experts told me similar stories as well. They said this motor would never run again, and the massive iron flywheel had forever been silenced by the passage of time. They told me that the corroded copper coils within, would never see frost again. I had a silent relic with only memories to be read on a museum plaque. In the end, they were gravely mistaken. ruclips.net/video/LdFclxIDY5k/видео.html
Everything can be fixed expecially this older stuff it’s the junk it mentality that people possess today is why they sale push mowers without drain plugs 🤦♂️great job 👍
Yeah I’d agree with you on this one. She had tons of character!! I find myself repainting the rusty hogged out ones, but she was well loved throughout the years.
@@partsandresto You work on this stuff a lot? Maybe I could get some motor wisdom from you. I have a 1920's single phase AC motor that was running, but when I looked inside all the wire insulation was pretty crusty. Can you rewind these things? Where do I even start? I've torn apart plenty of gas engines but motors are foreign to me.
Hey Dave,,have an old 1950's Craftsman 1/2 hp tore down on my bench now...I faith that it too will run once again. Check it out on my channel @ Bears Rod Shop,,,glad to be a new subscriber, great video, Bear
Hi there. Good job of doing it up. I'm a little bit of a collecter of these. Here is a link to my 1.5hp disc sander which is powered by one. ruclips.net/video/VvFso1cZUP0/видео.html At the end when you run it it should be a little quieter. I think making a shim or two up for the shaft where the fibre shims are would make that motor run even better

Good stuff man! Love that sound when it turns on and the plug in drama was awesome lol
Great rebuild. When working with motors that are dirty and greasy, electrical contact cleaner does a great job.
Ah! I didn’t know there was such a thing. I’ll get myself some! Thank you and thanks for watching!
RI motors are awesome. Vintage machinery !
They're the best! if not fun to work on and enjoy
Hey Dave, great video! I am trying to rebuild my motor too, and are wondering what you used to clean everything and how you changed the wiring. I am not experienced with rebuilding these but still want to try and tackle this myself. Any info you can share would be much appreciated. Thanks!
That's one heck of a centrifugal switch their very cool
So cool! Took me a while to figure out what I was looking at but in time and with some help, it all came together. I have a few monster motors lined up to restore, make sure you sub, they’ll be happening soon
Loved your video. Entertaining with a good amount of Know-how. Exactly what I’m looking for 🤘🏻🤘🏻
Definitely got my sub
Great video! Great restore 🙂 also loved the added drama 😁
Hahaha, twas necessary for this one!😂 so many motor pros genuinely told me to trash it.

This one had no speed control gents, perhaps a bit different than yours. Thanks for keeping yours alive as well!!
How do you remove the centripetal assembly? How is it held in? Mine is stuck and bending.
Any help with the wiring? I just bought a similar century dual voltage, but the leads are cut and very oily, don’t even know where to start to run it at 120 V
Are those little caps over the bearings for lubrication? Ive got a 40's wagner rep/ind 1hp motor and it has the same thing. 204 frame
a trick: watch movies at flixzone. Me and my gf have been using them for watching loads of movies recently.
@Marcellus Jeremias Yup, been using Flixzone for years myself :D
What type of oil is used in the oil cups? I am new to rebuilding electric motors.
Awesome retro. Question, I have a vintage GE motor. Need to replace start condenser, is there a positive and neg wire attachment? If so, how to I tell which connection is the positive side?
Thx
Is mineral spirits all you used?
Yeah pretty much.

Man what did you do to your fingers,could'nt help notice,but great work on that motor,have restored one myself,but not quite as old as yours

Matt send me some pics on IG and I’ll see if I can get you squared away
Very nice. Do you have an electrical background ?
Joe Fischer I’ve shocked myself a few times, does that count? Absolutely none, just some home electrical.
Good job man😊
what kind of oil/grease do ya put in the lil oiler holes on each end?
Did he hurt his hand in the process?
5:06 She didn't give in without a fight!
Nice job fella. Where did you find the motor ???

How did you re-wire that coil?
Didn’t. I just spliced in new wire where the crappy leads going out were.
I figured out how to do it. What a pain. Thanks for the reply.
What are the brushes made out of?
yes！incredible！
Good bro 👍👍👍👍👏👏👏
Hi excuse me please what kind of a electric motor is this?
Super sir
never seen that type of motor, were I worked we had big motors from the 30's still going but nothing like that.
Yeah she’s an old enough gal. Definitely packing some outmoded tech!
Good thing it was only a 3/4 HP motor, otherwise you would’ve needed all 10 fingers to restore! Good save 😁
Hahahahaha!!! I did most of the work with my toes (off camera)
Everything can be fixed expecially this older stuff it’s the junk it mentality that people possess today is why they sale push mowers without drain plugs 🤦♂️great job 👍
And it only cost you three fingers,way to go sparky.
Lol. I see what you did there
Drama queen!!...nice improv on the brushes!
Can you repair my 40 yr old motor that operates my elevator?
Looks good not painted!
I appreciate restores like the next guy or gal, but saddened when it's ruined by a gaudy paint job...
Yeah I’d agree with you on this one. She had tons of character!! I find myself repainting the rusty hogged out ones, but she was well loved throughout the years.
I rather enjoyed the incredibly unnecessary dramatic reveal.
Here for you Vinny.

"everybody" said it couldn't be fixed? that's an easy rebuild.
no one likes a recovery video like this =[
