Dremel 3000 Suddenly Stopped Working - Fix

I had my Dremel 3000 for about 3 years but in that time it had probably only had about 30 minutes use if that. You can imagine my surprise when having just started to remove rust from an escutcheon plate from my front door it stopped dead. No, a fuse had not blown, it doesn't have one. Neither had the fuse in the plug top blown. So what had caused this good as new Dremmel to depart this mortal coil?

A quick Google and perusal of a couple of video's suggested that assuming the brushes were in good order, they were, the fine copper wire from one or more of the Stator windings may have broken.

I followed the tear down in this video on Youtube:-


The broken wire can be seen at 2.36 minutes in.

Following the steps in the video I had no problem dismantling the Dremel or in rebuilding.

The broken wire was repaired by unwinding half a turn from the affected winding and after removing the broken wire from the termination clip, see the video, I inserted the wire and reinserted the termination clip. Be careful you do not snap the fine wire again.

Reassemble the Dremel without having any bits left over at the end, Make sure you do not lose the circular steel spring from the rotor shaft lock button in the process.

I am delighted to say the Dremel burst into life when switched on. Job done! For how long remains to be seen.
