Abstract
In an axial air-gap electronic motor in which a teeth surface of a stator and a magnet surface of a rotor are arranged opposedly along the axis line direction of an output shaft of the rotor with a predetermined gap being provided therebetween, the stator has a plurality of core members connected in a ring form with the axis line being a center, and each of the core members is provided with a connecting device for connecting the teeth surfaces to each other in an opposed state. In order to shorten the wire winding time and reduce the assembling manpower for the core members, a stator is formed by connecting a plurality of core members in a ring form with the axis line being a center, and locking ribs are provided as connecting devices for connecting the core members to each other in a rod form along the axis line direction.
