Abstract: To significantly improve a heat dissipation property of an axial gap rotary electric machine within a size necessary for configuring a motor. In an axial gap rotary electric machine comprising a stator and a rotor in an axial direction, the stator has a plurality of stator cores arranged in a circumferential direction and coils wound around the stator cores, and a heat pipe obtained by filling an inside of a metal hollow pipe with a refrigerant is arranged in a gap between adjacent coils formed in an outer diameter portion of the stator in a radial direction and a housing with a necessary insulation distance between the coils and the heat pipe. The heat pipe extends in a direction of a rotation axis and an opposite output side, and is in contact with a heat dissipating fin outside an end bracket on the opposite output side.

Abstract: The purpose of the present invention is to obtain a structure with which it is possible to improve the heat dissipation performance and efficiency of an axial gap dynamo-electric machine. Accordingly, the present invention is an axial gap dynamo-electric machine of such construction that a disc-shaped rotor in which permanent magnets are disposed is provided in the axial direction and a stator is disposed in the axial-direction center portion, wherein the outer circumferential side of a stator winding is in intimate contact with the inside diameter of a housing, embedding with a mold resin is used for the housing and a stator core and for a stator coil and the housing so that a connection is established with the housing, and the housing comprises a nonmagnetic, electrically nonconductive material.

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.
