Master Electric: Repulsion Induction Motor Restoration. Fabricating A New Short Circuiting Spring.

- In this video I restore a late 1920's Master 1 hp electric motor. The company was located in Dayton, Ohio. The motor is a repulsion start induction run but was not working. This was primarily due to a broken short circuiting necklace. After fabricating a new spring the motor now purrs like a kitten.

You named the packing material for the lubricant twice, & I missed the name of the product both times. Great video !I am 84 & earned my living in electrics & electronics. Today was the first time I had ever heard of a repulse induction motor. Live & learn. Cheers!
Its 100% organic wool yarn. Available at any craft store. Use 3 in 1 Electric Motor oil (Blue label bottle). Thank you for watching.
Congrats on getting hold of that original catalog in such great shape. Really enhances the experience.
Those old catalogs are nice when you find them. Unfortunately, my wife and I lost almost everything in a category 5 hurricane (Ian), that beatiful catalog was a victim too.
@@BencoVintageMachineWorks I'm very sorry to hear that. Stay strong!
@melotone3305 We were fortunate to be able to move into a new home with a garage I turned into a workshop. I posted a shop tour recently and you may enjoy it because I show many antique electric motors. Thank you for the kind words.
Really nice work Friend! Beautiful job on the spring switch!
Thank you!
@@BencoVintageMachineWorks it feels good to resurrect vintage equipment. Along with being outstandingly efficient, the work is beautiful.
I just love watching these antique motors come back to life! Phenomenal work Terry! The old motors are stunning and as good as new when you're done working on them. They sure don't build stuff like they used to! Another great video, I'm addicted!
Thank you. Glad you enjoy watching the videos.
This is cool. I just restored the exact same motor about 6 months ago. I plan on using it on a 6" Walker Turner jointer that I also restored. Owning and using these old gems makes me feel like a rich man.
Those old Walker Turner jointers are nice. Im sure you will enjoy it. Agree with you about owning these vintage gems. They were made to last. Thanks for watching.
@@BencoVintageMachineWorks thanks. I have my jointer up and running and I'm very happy with it. I do have a question, what type of oil should I use for the bearings? Thanks.
@@bradleymasson1777 If your motor has oil wicks you can use a quality 10w non-detergent oil like Zoom Spout. This lighter weight oil facilitates the capilary action that wick oilers use. If your motor has ring oilers then use 3 in 1 Electric Motor oil which is a 20w. The slightly heavier viscosity keeps this oil from slinging off the rings.
Just found your site, thank you sir, please make more videos.
That is my plan. Thank you.
Beautiful job on the restoration!
And really helpful video too! There's nothing like the sound of a repulsion motor starting up!
Thank you. Glad you found it helpful!
Ура новое поступление.Приятно смотреть как моторы чинят.
Thank you for watching.
Great video, very detail. you do nice clean detailing.
Thank you. These Master motors were very well built and worth saving. Glad you enjoyed it.
Excellent restore and video!
Thank you. Glad you enjoyed it.
I really enjoy watching your videos I love old stuff especially old motors and etc growing up in that error when that stuff was still around besides I work on all machines the stuff that nobody wants to work on or doesn't have faith in or just so used to plug it in a scanner but keep them coming man I enjoy it!!!
Glad that you enjoyed the video. These old motors were definitely built to last.
Outstanding job! Fantastic rebuild and tutorial from start to finish. What a lovely motor and it runs perfect. Great stuff...
Glad you liked it John. I enjoyed watching the video about the antique tube and knob electrical insulation too. Thanks for recommending it...
Great video!!
Thank you. Glad you enjoyed it.
Super. Poland motor Siemens schuckert
Thank you
If OBI-WON A.K.A ScoutCrafter says you're cool then BY GOD I will subscribe!!! WOO HOO!!!!!!!
Thank you for subscribing. John is a great friend and I have enjoyed his channel for some time .
👏👏👏
Thanks
Tremendous work rehabilitating that lovely motor. At about 8:50 you mention, at least twice, that you needed to wait for the windings to "dry out" before applying new varnish. Did you use a soap/water wash, or some other liquid? I totally missed that.
I prefer not to hose off the windings and consider it a last resort. In this case, there was an oily liquid that had damaged the windings and I had to use Dawn detetgent and gently clean them. An electric motor stored in a garage, basement or outside can have too much moisture too. When I speak of "drying out" its refering to warming and drying the windings using a heating pad until they are nice and toasty before applying a new coat of varnish.
@@BencoVintageMachineWorks Thank you. I've seen a lot of mentions cautioning against hosing off or washing with pressure for fear of inadvertently breaking some of the winding wires. I could more easily see using a household spray bottle and tap faucet rinse followed by either the warming pad or perhaps your heated fan. Much appreciated.
Glad you enjoyed the video
Wonder where brushes are found for these? Curiously my 1.5hp is shunted. It didn't look like yours are.
Eurton electric has brushes. I usually find them on ebay. You can buy slightly oversized and file them down easily enough. I removed the shunt wires on these as I often do. Reason being that sometimes the non-OEM replacement brushes may have the wires coming out in the wrong place and this can cause it to get hung up. A properly cleaned and maintained motor will run fine without them, as seen in the video.
Fantastic job as always! Where do you source the bearings? Would love to see more detail on making the spring. I think these are the first non-straight motor studs I’ve ever seen.
Hello Brian,
Thanks again for the kind words. When possible, I try to order bearings from McMaster-Carr. They also carry the extension springs needed for the shorting necklace. As you probably know, VMO has a wiki on replacing the spring on a Delta repulsion with step by step photos. The process is pretty much the same as I have done here. I did feel that those bent motor studs were inferior to the straight ones. These end bells are easily mis-aligned with each other because the motor studs allow way too much play. Glad you enjoyed the video!
Great video. What type of electrical varnish/insulation paint do you use?
If I need to apply a heavier coat I use the brush on Glyptal insulating varnish which is usually red in color. For lighter applications I use Sprayon EL-600 clear spray varnish. Both are great products. Thank you for watching.
Can you also post where you got the bushings? I am doing the same to a 1/2hp version of that same motor (first time) and I'm using your video as a guide. Also, where did you get the 3 jaw puller to remove the bushings? That thing is huge.
@@danielcargill5388 The puller is an old USA made Craftsman. As for bearings, I usually order from Mcmaster-Carr. Sometimes you need to bore out new bushings ever so slightly to get a proper fit so be prepared to do that if needed. A set of adjustable hand reamers comes in real handy for that task.
