Claims

[Scope of Claim for Utility Model Registration] (1) A rotor, a circumferential yoke disposed opposite to the outer periphery of the rotor, and field poles fixed to the inner peripheral surface of the yoke. A rotating electrode comprising a field device comprising: a rotating electrode having an axial width of the field poles such that a demagnetizing side on which an armature reaction magnetic flux acts is larger than a magnetizing side. (2) The field poles are composed of composite field poles that are divided in the axial direction, and the field poles on the increasing side are made of a magnet material that has high magnetic flux density characteristics, and have high coercive force characteristics. Claim No. 1 for Utility Model Registration, in which the demagnetizing side field poles are constructed from a magnetic material having
Rotating electric machine as described in section. (3) The rotating electric machine according to claim 1 or 2, wherein a magnetic pole piece made of a thin plate member of soft iron is attached to the inner circumferential surface of the field A pole. (4) The rotating electric machine according to claim 3, wherein the field magnetic poles are configured to be tapered in the circumferential direction, and rectangular magnetic pole pieces are attached to the inner peripheral surface of the field magnetic poles.
