1. A rotor, comprising:
a first rotor core including a substantially disk-shaped first core base and a plurality of primary claw-shaped magnetic poles formed at equal intervals on an outer peripheral part of the first core base, the primary claw-shaped magnetic poles protruding radially outward and extending in an axial direction; a second rotor core including a substantially disk-shaped second core base and a plurality of secondary claw-shaped magnetic poles formed at equal intervals on an outer peripheral part of the second core base, the secondary claw-shaped magnetic poles protruding radially outward and extending in the axial direction and each secondary claw-shaped magnetic pole being arranged between corresponding primary claw-shaped magnetic poles; and a field member arranged between the first core base and the second core base in the axial direction, wherein, when magnetized in the axial direction, the field member causes the primary claw-shaped magnetic poles to function as primary magnetic poles and the secondary claw-shaped magnetic poles to function as secondary magnetic poles, wherein the field member is formed by placing a plurality of members one over another in the axial direction. |
