摘要： A claw-pole motor according to the present invention has the maximum occupancy ratio of a wound wire by using a rectangular electric wire for the annular coil of a claw-pole-type motor, winding the rectangular electric wire into an almost analogous shape with the cross section of a wound-wire space and setting the rectangular electric wire. Moreover, a lead-out portion is formed by keeping the shape of a lead-out portion as a rectangular wire, the terminal portion of the lead-out portion is deformed into a predetermined connector shape by appropriate processing method and a insulating coating is removed. Thereby, it is possible to greatly decrease man-hours of a terminal connecting portion.
