1. An axial gap type permanent magnet electric rotating apparatus comprising a first rotating disk and a second rotating disk having surfaces perpendicular to a rotation center of a shaft and containing a magnetic material, a first rotor to be rotated by a shaft and attached, along a circumferential direction, a plurality of permanent magnets whose magnetic-pole direction is an axial direction on an axial-direction surface of the first rotating disk, a second rotor to be rotated by the shaft and attached, along the circumferential direction, a plurality of permanent magnets whose magnetic-pole direction is the axial direction on an axial-direction surface of the second rotating disk, such that axial-direction surfaces of the permanent magnets oppose axial-direction surfaces of the permanent magnets of the first rotor, and an armature arranged between axial-direction opposing surfaces of the first rotor and the second rotor, wherein
all the magnetic-pole directions of the permanent magnets attached to the surface of the first rotor, which opposes the second rotor, are the same; all the magnetic-pole directions of the permanent magnets attached to the surface of the second rotor, which opposes the first rotor, are the same; a portion between two permanent magnets along the circumferential direction of each rotor is made of a magnetic material having substantially the same size as that of the permanent magnet such that axial-direction surfaces are the same between the permanent magnets on two sides in the circumferential direction; and between the first rotor and the second rotor, a magnetic flux flows along the axial direction while making a loop and passes through the armature. |
