| Zusammenfassung: | In order to obtain an electric rotating machine which can improve rotating machine efficiency by suppressing a harmonic component of rotor magnetomotive force and reducing harmonic core loss, a permanent magnet is furnished in some of inter-magnetic pole portions, the inter-magnetic pole portion being formed between a first claw-shaped magnetic pole portion and a second claw-shaped magnetic pole portion; the shapes of a first chamfered portion and a second chamfered portion, which are provided in the inter-magnetic pole portion where the permanent magnet is inserted, differ from those of a first chamfered portion and a second chamfered portion, which are provided in an inter-magnetic pole portion where the permanent magnet is not inserted; and/or the shapes of a first magnetic flux adjusting portion and a second magnetic flux adjusting portion, which are provided in the inter-magnetic pole portion where the permanent magnet is inserted, differ from those of a first magnetic flux adjusting portion and a second magnetic flux adjusting portion, which are provided in the inter-magnetic pole portion where the permanent magnet is not inserted. |
