Claims

[Scope of utility model registration request]

A plurality of permanent magnets are fixed at equal intervals in the circumferential direction on the outer circumferential surface of a ring-shaped yoke fitted and attached to the rotating shaft, or on the entire outer circumferential surface of the rotating shaft, and non-magnetic permanent magnets are attached on the outer circumferential surface of the permanent magnets. In a rotor of a rotating electrical machine equipped with a protector, a plurality of protrusions are provided at equal intervals in the circumferential direction on the outer circumferential surface of the yoke or the outer circumferential surface of the rotating shaft, and on the inner circumferential surface of the permanent magnet protector. A rotor for a rotating electric machine, characterized in that the permanent magnets are disposed at appropriate positions in the circumferential direction by being inserted into gaps between the magnets at the inner and outer peripheral portions of the permanent magnets.
