Axial gap type permanent magnet electric rotating apparatus and method of manufacturing the same

摘要

According to one embodiment, there is provided an axial gap type permanent magnet electric rotating apparatus including a first rotor (2-1) and a second rotor (2-2). All a magnetic-pole directions of a permanent magnets (3) of the first rotor (2-1), which opposes the second rotor (2-2), are the same. All the magnetic-pole directions of the permanent magnets (3) of the second rotor (2-2), which opposes the first rotor (2-1), are the same. A portion between two permanent magnets (3) along a circumferential direction of each rotor is made of a magnetic material having substantially the same size as that of the permanent magnet (3) such that axial-direction surfaces are the same between the permanent magnets (3) on two sides in the circumferential direction. Between the first rotor (2-1) and the second rotor (2-2), a magnetic flux flows along an axial direction while making a loop and passes through an armature (6).
