I figured out a way to make the motor rev higher without taking away too much torque if any(i didn't notice any)....I lightened the armature
THis is what you need
1. drill(something that can hold the armature and spin it fast!)
2. file(probably not too course like the one i show in the pic)
What i did
1. I tightened the lock around the armature on the drill
2. set the drill to high speed
3. put the filedown on a table(not on your leg like in the picture)
and grind the metal part till it touches the plasticon the bottom and top
when you/re putting the armature back inside the can you'll notice how much smaller in diameter it is now!
Warning!!!! don't file down the armature so much that you hit a wire if you do you'll probably ruin the windings and need to rewind it with more wire!

WOAH i didn't realize i had put my motor in the wrong can!...
i just swapped the magnets of my spinbrush into this can which i thought i had and now this thing is a beast! the lighter armature really helps torque...has anybody else tried this?

lighter armature...higher revs
