摘要:
When one of armature coils (9, 9a, 9b) is in a beginning of a commutation process, a center line of a trailing end tooth (12b, 12d) of a corresponding group of teeth (12, 12a, 12b-12d), around which the one of the armature coils (9, 9a, 9b) is wound, is generally aligned with a corresponding boundary between magnets (2, 3). When the one of the armature coils (9, 9a, 9b) is in an end of the commutation process, a center line of a leading end tooth (12a, 12c) of the corresponding group of the teeth (12) is generally aligned with another boundary between the magnets (2, 3).
