Claims

[Claims for Utility Model Registration] 1. An iron core formed by laminating fan-shaped thin steel plates and permanent magnets are arranged alternately in the circumferential direction, and end rings are provided on both end faces in the axial direction of the iron core. and the permanent magnet are tightened together to form a single body, and the rotary shaft is fixed to the end ring. In the permanent magnet rotor, the fan-shaped thin steel plate has an elongated hole extending along the center line approximately in the center of the sector-shaped thin steel plate. an end ring provided on both end faces in the axial direction of the iron core, the end ring having a boss protruding from the center and an elongated hole of the same pitch and the same size as the elongated hole of the iron core; and a through pin that fits into the elongated hole of the end ring and has both ends caulked. 2. A screw hole provided perpendicularly to the shaft hole of the boss and a set screw screwed into the screw hole are provided in both end rings, and a conical hole is provided at a position axially shifted inward from the center of the two screw holes. 2. A countersunk-shaped hole in the shape of the rotating shaft inserted into the shaft hole is provided in the rotating shaft, and a tip of the set screw presses a conical surface in the countersunk-shaped hole to fix the end ring and the rotating shaft. Permanent magnet rotor as described.
