摘要
In a vehicle AC generator, the rotor has two pole pieces that axially enclose a field winding, while a tubular stacked-lamination core formed of axially stacked magnetic laminations is mounted with its inner circumference in contact with outer circumferences of the pole pieces. A plurality of axially extending elongated permanent magnets each magnetized in the circumferential direction are implanted in the stacked-lamination core, with adjacent permanent magnets polarized in opposite directions, so that axially extending circumferentially alternating N and S rotor poles are formed at the outer circumferential surface of the stacked-lamination core by the magnetic flux of the field winding.
