Abstract
An axial gap electronic motor includes a stator and a rotor disposed opposingly with a predetermined gap. In order to provide an easy assembling operation of the stator, the stator includes a plurality of pole members annularly connectable. The annular stator core is obtained by connecting each of the pole members to which coil winding is previously applied.
