Abstract

A rotor for an electric machine includes a rotor main body which has at least two poles between which in the circumferential direction of the rotor is disposed at least one pole gap, and a rotor shaft which is coupled in a rotationally fixed manner to the rotor main body. The rotor has a support device which has a covering body that is configured for covering at least regions of an end side of the rotor main body. The support device has an annular body, which is different from the covering body, and in the direction of radial extent of the rotor is braced in relation to the rotor main body, on the one hand, and in the direction of radial extent of the rotor is braced in relation to the covering body, on the other hand.
