The Matt Motor tutorial shows how to wind an armature to make a two-pole retrograde device which resembles the earliest of electrical motors. This sort of motor construct is necessary to produce current pulsations with inductive kickback to the remainder of whatever circuit it is connected to. This method of winding commutated armatures was discontinued many years ago because of problems with brush sparking (a problem Tesla devoted much work towards) and reduced motor life. It is possible to duplicate this motor action in a much more reliable manner with brushless design and electronic pulse control should it be desirable. Whenever I see motor rewinds done on a bare armature which doesn't seem to have in place the necessary insulating material I wonder... This video shows the proper method of preparing the slots in the armature for rewinding. It is in Pakistani Language but the illustrations are quite clear. Notice the insulating material both in the slots and at the slot ends covering the surface of the metal surrounding each end of the shaft. Putting the windings on bare steel is never a good idea. It is not possible in Matt's tutorial to tell whether he has taken the necessary precautions prior to winding.
