Claims

[Scope of utility model registration request]

(1) In a rotating field-type rotating electric machine in which a plurality of permanent magnets are arranged on the circumferential surface of a field core to form a rotating field, a polar arc piece made of a magnetic material is arranged on the outside of the permanent magnet. A rotating field-type rotating electrical machine characterized in that the pole arc piece and the field iron core are integrally fixed via a connecting member.

(2) Utility Model Registration The rotating field type rotating electric machine according to claim 1, wherein the polar arc piece is constructed by attaching end plates made of non-magnetic metal to both ends of a laminated steel plate.

(3) Utility model registration Claims 1 or 2, wherein the field core has a regular polygonal cross section perpendicular to the axis, and the permanent magnet is attached to the outer surface of the regular polygon. A rotating field type rotating electric machine characterized by a rectangular cross-sectional shape.
