  • Publication number: 20190173334
    Abstract: A rotating electrical machine rotor includes multiple claw-shaped magnetic pole portions, permanent magnets, and a tubular outer peripheral iron core portion. The claw-shaped magnetic pole portions face a stator in a radial direction, are arranged with clearance spaces in a circumferential direction, and are alternately magnetized to different polarities in the circumferential direction by power application to a field winding. A permanent magnet is arranged in each clearance space such that the polarity of each of side surfaces facing the claw-shaped magnetic pole portions in the circumferential direction is the same as the polarity of a corresponding one of the claw-shaped magnetic pole portions. An outer peripheral iron core portion covers an outer peripheral side of the claw-shaped magnetic pole portions. The outer peripheral iron core portion has a tubular body portion and magnet holding portions configured to hold the permanent magnets.
