Well, I just picked up my spin brush tonight, so here you go...

First thing I have noticed about this motor is that it has no bearing in the endbell at all. Not even brass. The motor shaft just rides in plastic.

Fortunately, I have a ball-bearing endbell laying around.


The brushes look like the cheesy ones that the 1.99 motor uses, and they were coated in grease.

The motor is noticably torquier than either the stage 1 or two motors, though it spins quite a bit slower.

After unwrapping the armature, I can say that it uses 70 turns of ~32 gauge.

So where is all the torque coming from? I think it's the magnets. They look a bit thicker than the other motors I have open on my bench. Makes sense, since the tighter the magnet/armature tolerance, the more torque you get.

Time to swap these magnets into the Squat BB can along with the 25 turn armature I just wound. Oh, and it only took me about 30 minutes to wind it. No torque, but noticably faster than stage 1 or 2. We'll see what the better magnets do...
