What's the Best Way to Clean Dielectric Oil from a Stator Winding?

Auto brake and electric motor cleaner from an Auto Parts Store should fill the bill!

Read and heed the instructions.

Avoid the vapor/fumes. Work outdoors or where there is plenty of ventilation!

Have you tried 409. Try taking oil in a shallow pan and spray 409 in the pan with thin oil as an experiment and see if it disperses. I have used it on baked on oil on baking pans and let it set and it works real good!!!!

Try Simple Green cleaner. The stuff works wonders. I think it is far better than 409. I use it to clean aircraft starter-generators, and even oil and greased bearings. It removes stuff that even solvent will not work on. Be carefull if you have sealed bearings though, it will dissolve the bearing lube. Soak it for 10-15 mins. using full strength and rinse with plain water. I would advise not to use anything like spray solvent like brake/carb cleaner. Those will dissolve the varnish on the windings. Make sure you dry it using hot air to remove all the water to prevent corrosion of the iron core.

Could you please send me by fax or e-mail a cross section drawing of your starter-generator?

I am developing a brushless one and I would like to compare the two machines.

I would thank you for the main specifications: DC votage an ampers, Alternating current frequency and amperes and voltage.

I recommend using PowerGreens H2Pro Cleaner/Degreaser. It's a green cleaner that actually breaks down grease and oils into their base fatty acids and allows for a better cleaning with no residue. Place parts in aqueous solution, agitate or scrub, then rinse clean. I would also recommend blowing off the part to remove all excess water. This will get oils and grease off in a safe manner without the worry of solvents, voc's or other toxic chemicals in the mix. Check it out at www.thepowergreen.com

There is a product used to clean grunge of motorcycles called S100. This stuff will cut the oil easily. Rinse in a lot of very hot water and let it dry well. Should be fine after that.

...or WD40...

as with other noted cleaners S100 will clean the grease and oil out of your bearing too!.

If you leave it on to long it will dry and slightly etch the area it was on. These from experience. It is a very effective cleaner.

Did this stuff environment safe? when you rinse off with hot water into the drain.

What is MSDS of this S100 solvent?
