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

Abstract: Stator coils each consist of a plurality of rectangular conductor coil pieces, the adjacent connection ends of which are connected to each other on the outer diameter side of a stator. The coil pieces each have: a folded portion folded in a rotation axis direction on the inner diameter side of the stator; inner diameter-side open leg portions opened from both sides of the folded portion toward the circumferential directions of the rotation axis; linear portions each bent from each of the inner diameter-side open leg portions and disposed so as to pass through the stator from the inner diameter side to the outer diameter side; and an outer diameter-side open leg portions opened from the linear portions toward the circumferential directions of the rotation axis and extending to the connection ends. The inner diameter-side open leg portions extending to the folded portion have a correction portion for correcting the position of the rectangular conductor and are formed so as to align the connection end extending to the correction portion with the connection end of the adjacent coil piece.
