Abstract
In an axial air-gap electronic motor having a stator that is formed by annularly connecting a plurality of core members around an axis of a rotor output axis, an insulator that insulates a winding portion of a stator core of each core member is formed in the winding portion in the shape of a bobbin having a pair of flanges, a winding draw-out portion is formed between abutted end portions of the flange, and a crossover wire of a winding is pulled out from the winding draw-out portion to outside the core member, whereby it is possible to positively perform routing treatment from the winding portion of the winding to the crossover wire and it is ensured that the crossover wire can be positively fixed without bringing a crossover wire of a different phase into contact.
