Abstract
The back EMF generated in armature coils is substantially balanced by causing the coils located a greater distance from the axis of rotation of the armature to have fewer turns than the coils located closer to the armature axis of rotation. Alternatively, rather than decrease the number of turns in the coils, the same balancing affect can be achieved by increasing the electrical resistance of the coils located a greater distance from the armature axis of rotation.
