Instructables

My Dremel 395 quit working when I was twisting the wire counter-clockwise to get it into my z-axis mount. I read on the forum where someone tested 6.5/7 ohms between the stator wires.

One of mine was broke so I fixed it! I hope someone else can use this to fix theirs too.

First determine if your stator has 6.5/7 ohms between each coil set. There are two coils to test. If there's no reading then you have a short. If one is broke then you have to solder it back! The problem is that the wire is now too short to put back into the connector. The solution is to (not in this order) solder a tab onto it and reconnect it with the pin.

I had a craftsman dremel I bought years ago that broke.

My fix was not the same but resulted n no soldering or drilling.

What I did was unwind the entire coil and rewind it back so the wire was long enough. The dremel works even now after 5 years. :)

Thanks for posting this. I had the exact same problem and followed your instructions. I'm pleased to have a great Dremel working now. Thanks again!

Great tip. I would also buy a new field assembly piece, that's the stator you repaired and keep the repaired one as a spare. Its ~ $5-10, shipping included to the USA, direct from Dremel.

Good idea. Also the bearings go bad too. I don't remember the dimensions off the top of my head but they can be bought from the internet for cheaper than ace hardware.
