Hi. How would you suggest cleaning a very greasy motor? It's an old motor with cloth covered wires. The stator, armature and windings are just caked with grease (it shares a housing with a geared grease filled transmission). I've heard to use mineral spirits or hot water and soap. Then heat an oven to about 100 degrees and let it dry out for several hours. I figure soap and water may be less aggressive on the old windings, but don't necessarily like the idea of using water. I have also seen brake cleaner used by some. Thanks!

I worked for an electric motor rewind/repair shop. I used to write the quotes You disassemble, steam clean the motor (hot steam, simple green, zep) Then you bake at about 250-275 for 4-6 hours 100 degrees is not nearly enough. The objective is to evaporate all moisture. Water boils at 212 100 degrees gives you warm water 250-275 for 4-6 hours assure all the moisture is “baked out”

We saved motors that got flooded. As long as you don’t energize them, they can be saved Disassemble, clean the inside (flood water is dirty…so the same steam clean and bake applies) 250-275 for 4-6 hours and the motor is saved

Thanks it's very instructive What type of spray can clean armature windings

The spray I used is only compressed air to blow away any metallic particles

Wow very nice. I am rebuilding a greenhouse inflation fan-extremely small squirrel cage motor. As you might expect, it is covered in rust. Even the copper wiring. It is super thin copper winding so I have to be very careful. I had no idea what I was doing when I started this 3 weeks ago. Thank you for your video!

@@TheLabOtomy Well, I added felt bearings, sanded the rotor...and put it back together and it starts and stops. Now I think I have a bad winding. checking that next !

Found my dad's chop slide saw in the man corner of northlondon most overgrown garden. We removed all his u powered tools from there bin bag covers and I want to bring them back to life, it's a mac alilster slide chop saw with twin lazer guide so it's nothing much to get excited about. My dad's passed away and I should have made shore his tools were taken care of. He died while tinkering away and I put a tarp over everything cut off the power and let a year go by.. My bad my bad.. I'll strip every thing down clean it up and replace what carny be fixed. I'm doing it soon as I finish this last bottle of his home brew. At lest that improved after 14, months of neglect.. Bleeding spot on lads. Cheers dad.

Thanks for making the video concise and void of the corny lo-fi DYI electro bank music. Question: is there any type of anti-rust lubrication one could apply like dielectric grease? Since it's conductive and what-not.

The armature is submitted to high RPM so am keeping those dry. Anti-rust lies more around storage in a dry area.

@@TheLabOtomy First off thanks for the speedy reply. I should have mentioned it is the for a small sized fan I have that I just busted out for summer. You could tell that it is really fighting itself to even spin at low rpms. On the highest setting. I plan on taking the armature and cleaning it. As far as my options on hand for afterwards is: dielectric paste, oil for my electric clippers,pb blaster,and silicone spray. I can always hit up the big box stores,but seeing if anything I have on hand would work. Thanks again for videos and speedy reply!

Could this method be used with brushed motors for rc cars?

why does that matter? The part that the contacts touch is above the part you cleaned.

Rust can spread across more sensitive parts and alter rotor balancing

Rust is conductive and shorts the laminated plates which effects eddy currents and flux density.Look up why a stator is not a solid block of metal rather they are stacked metal plates.

@@leoszilard3998 Its been a year but I think I meant why did he not also clean the dirty contact portion above the plates too (commutator) I agree the rust could case (some) eddy currents and power loss doubt it would stop it from working as the stacks are for efficiency. I have not cleaned enough of them to really know how much rust affects them. But yes I think your answer is the best one so far. I imagine it would create hot spots in area and heat up the meat more than it normally would. I thought those plates were insulated, so after cleaning you must spray a think layer of clear coat on them to prevent more rusting?

Shiny and crome.
