Abstract:
1. An axial air-gap electronic motor comprising: a stator and a rotor arranged in an opposed manner with a prescribed air gap provided along an axis direction of a rotor output shaft of the rotor, and a plurality of core members arranged in the stator annularly around an axis of the rotor output shaft, the core members being mutually connected via prescribed connection means, wherein each of the core members is formed in a shape of a bobbin and has a stator core and an insulator insulating a winding portion of the stator core, the insulator has a pair of flanged portions parallel to a teeth face of the stator core, and at least one of the flanged portions is provided with a winding draw-out portion for drawing out part of the winding to outside the core member, and the winding draw-out portion comprises a notched portion formed in at least one of two circumferential end portions of the flanged portions, the notched portion being located between abutted end portions of the flanged portions in connecting adjacent core members to each other.
