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.
