Updates

Update 02/10/2012

mentar: Coils fine, commutator covered in a beefy layer of carbon, one brush almost gone. Replaced the brush with a smaller one from a one of the motors in the "motors" box, cleaned the carbon residue off the commutator and it works, sort off. The speed controller only works for a small range and the speed is constant after about 20%, this could of-course be due to a brush that wasn't meant for it. I'd still advice people against using it just yet, but if someone who has seen it working before the fault can take a look and confirm that it's not behaving properly that would be great.

Update 05/09/2012

Billy has offered to fit the brushes if someone orders the brushes. Expressed concern about the off-centering of the armature, which will probably require the motor to be replaced in the future.
