ABSTRACT:
Stable electrical connections between coils and a commutator are realized without causing slackening of the coils wound on individual magnetic teeth. An armature of a rotary motor includes an armature core structured splittably into magnetic tooth members which are individually wound by concentrated-winding type coils, and a commutator having the same number of segments as the number of the magnetic tooth members, the individual segments having connecting terminals, wherein an end portion of the coil concentratedly wound on one of the magnetic tooth members is connected generally in a straight line to the connecting terminal of the segment which is located at a position offset in a circumferential direction by a specific angle from the aforementioned one magnetic tooth member, and a conductor line connected to the connecting terminal of the segment is concentratedly wound on another magnetic tooth member adjacent to the aforementioned one magnetic tooth member.
