Abstract
A rotor includes a field member arranged between a first core base of a first rotor core and a second core base of a second rotor core in the axial direction. When magnetized in the axial direction, the field member causes primary claw-shaped magnetic poles to function as primary magnetic poles and secondary claw-shaped magnetic poles to function as secondary magnetic poles. The field member is formed by placing a plurality of members one over another in the axial direction.
