Multiple first coils are wound on the first insulating arms and multiple second coils are wound on the second insulating arms. The first and second silicon steel seats overlap each other with the first and second insulating arms alternately positioned. In this case, the first and second coils wound on the first and second insulating arms are alternately positioned to intersect each other. The first and second silicon steel seats can assembled as necessary to enhance compatibility of the silicon steel seats and lower manufacturing cost. Moreover, the winding operation of the coils can be speeded.

    Abstract: In a brushless motor including a rotor having 2n poles and a stator having 3n slots, segment magnets arranged, in three columns, in the axial direction, thus constituting rotor poles. The segment magnets of adjacent columns, which are identical in polarity, are displaced in the circumferential direction, thus forming a three-stage step-skew structure. The skew angle θskew of each segment magnet is set to an electrical angle of 60° to 75°. The center angle of θm of each segment magnet is set to 46.8° to 52.7°.
