ABSTRACT:
When one of armature coils is in a beginning of a commutation process, a center line of a trailing end tooth of a corresponding group of teeth, around which the one of the armature coils is wound, is generally aligned with a corresponding boundary between magnets. When the one of the armature coils is in an end of the commutation process, a center line of a leading end tooth of the corresponding group of the teeth is generally aligned with another boundary between the magnets.
