Claims

[Scope of utility model registration request]

(1) It has a composite structure in which a main magnetic pole made of a permanent magnet and an auxiliary pole made of steel are adhered in the circumferential direction, and the auxiliary pole is attached to the inner circumferential surface of the yoke by a mounting means, and the main magnetic pole is A plurality of field poles glued to the inner circumferential surface of the yoke and an elastic member are bent into a U-shape from a thin metal plate, with both ends of both sides protruding in the axial direction from the field tips, and a circular shape. It is bent so as to protrude outward in the circumferential direction, and the tip in the axial direction is rounded (
Each of these holding frames is inserted between the respective field poles in the axial direction with the bottom in contact with the inner circumferential surface of the yoke, and both sides of the holding frames are inserted into the yoke. The side surfaces of the field poles are elastically pressed, and the clamping material locks the outer ends of both field poles with the locking protrusions at both ends, thereby holding the main magnetic pole on the auxiliary pole via the holding frame. A field device for a magnet direct current machine, characterized by:

(2) A field device for a magnetic rotating electric machine according to claim 1, wherein the locking protrusion of the holding frame is formed by bending outward in an arc shape in the circumferential direction.

(3) The field device for a magnetic rotating electric machine according to claim 1, wherein the locking projection of the holding frame is formed by being folded outward in the circumferential direction.

(4) Utility model registration claims 1 to 3, characterized in that the holding frame is formed by bending a thin steel plate.
A field device for a magnet rotating electrical machine according to any one of the paragraphs.
