Abstract:
1. An axial gap type rotating machine comprising: a housing; a rotating shaft rotatably supported in the housing; two rotors capable of rotating integrally with the rotating shaft, the rotors disposed to face each other with a distance therebetween in an axial direction of the rotating shaft, comprising two rotating plates and permanent magnets disposed in a circle around the rotating shaft on at least one of opposing faces of the rotating plates so that magnetic pole surfaces of the permanent magnets are positioned perpendicular to the rotating shaft; and a stator fixed to the housing, the stator disposed in an air gap formed between the rotating plates facing each other, comprising a fixing plate and coils disposed in a circle in the fixing plate so as to face the circle of the permanent magnets, wherein each of the coils comprises a winding wire formed by a bundle of at least two coil conductors having rectangular cross sections by aligning at least one of long sides and short sides thereof, and the winding wire has an outer circumference covered with an insulating coating and is wound such that the long sides in cross section of the coil conductors are positioned perpendicular to the magnetic pole surfaces of the permanent magnets.
