ABSTRACT:
An axial gap rotating machine rigidly fixing permanent magnets without reducing magnetic flux and having a high output has: a housing; a rotating shaft rotatably supported in the housing; two rotors having disks rotatably integral with the rotating shaft, and permanent magnets arranged concentrically in spaced relation to each other on at least one side of surfaces of the rotating disks in spaced relation to each other on at least one side of surfaces of the rotating disks in spaced relation to each other; and a stator arranged between the rotors, spaced from the rotors and fixed to the housing, the stator having a plurality of coils disposed concentrically around the rotating shaft spaced from each other; wherein magnetic flux generated from the permanent magnets of the rotors intermittently penetrates the interior of each of the coils as the shaft rotates, wherein the rotating disk has a concave portion in the surface facing the stator in which the permanent magnets are disposed so as to protrude.
