ABSTRACT:
An axial gap coreless motor includes a stator including a stator yoke having a surface and being composed of a plurality of laminated layers of silicon steel sheets secured together, a wiring substrate having a surface and being disposed on the stator yoke surface, and a plurality of coreless coils annularly disposed on the wiring substrate surface; and a rotor including a rotor magnet having a plurality of circumferentially arranged magnetic poles, wherein the rotor is rotated relative to the stator such that the rotor magnet axially confronts the coreless coil over an air gap.
