摘要:
A claw pole type motor includes first and second claw poles opposed to each other and each including a radial yoke portion having an inner diameter side and an outer diameter side, a plurality of pole portions arranged on the inner diameter side, and axially extended, and an outer peripheral side yoke portion extending on the outer diameter side. A stator core is provided having an inner diameter side, and is formed so as to cause the pole portions of the first claw pole to be meshed with the pole portions of the second claw pole. A rotor is arranged on the inner diameter side of the stator core with a circumferential gap being defined therebetween. In order to provide high efficiency while simplifying manufacturing, the first and second claw poles are formed by compacting of magnetic powder.
