Abstract
Provided are an axial gap motor and a method for manufacturing a winding therefore capable of realizing low cost and high output without causing a jumper wire of a continuously wound coil obtained by winding an insulated conductor wire to protrude from the coil. The axial gap motor comprises a stator which is obtained by disposing a plurality of coils in a ring shape, and a rotor which is rotatably attached so as to face one or both principal surfaces of the stator and includes a plurality of permanent magnets corresponding to the plurality of coils of the stator. Each of the plurality of coils constituting the stator is formed by continuously winding one or more insulated conductor wires as coil wires around two or more separation cores. A core lamination thickness is indicated by 'L1'' and a radial length of each coil is indicated by 'L2', a relation of L2<L1′ is satisfied. In each coil, a length of a jumper wire of the insulated conductor wire continuously wound on the two or more separation cores is equal to the radial length “L2” of the coil.
