Claims

[Scope of utility model registration request]

Rotation of a rotating electric machine in which a plurality of ring-shaped or circumferentially divided permanent magnets are arranged and fixed in multiple rows in the axial direction on the outer circumferential surface of a ring-shaped yoke that is fitted and attached to the rotating shaft or on the outer circumferential surface of the rotating shaft. A ring-shaped notch groove is provided on the outer periphery of both axial ends of each permanent magnet in the axial row, and a ring-shaped notch groove is provided on the outer periphery of each end face in the notch groove on both axial ends of the permanent magnet. Fitting the protrusions of a non-magnetic side plate having protrusions, and inserting a non-magnetic spring ring into the notch groove inside the permanent magnet, tightening each of the permanent magnets in the radial direction. A rotor for a rotating electrical machine characterized by:
