Abstract
A rotor of a rotary electric machine according to the present invention includes: a rotor core arranged on the outer circumferential side of a rotor shaft; and a plurality of magnetic poles fixed to the rotor core and circumferentially arranged on the rotor core, the rotor including a non-magnetic ring attached by insertion to the outer circumference of the plurality of the magnetic poles and having a substantially polygonal shape in outer circumferential shape. The non-magnetic ring is configured such that the inner circumferential length L of the non-magnetic ring before assembly with respect to the length of an envelope Lof tangent lines each between the outer circumferential surface of the magnetic pole and the outer circumferential surface of the adjacent magnetic pole is set to L≦L. An object is to obtain the rotor of the rotary electric machine capable of achieving reduction in size and cost.
