Rotor having a support device, electric machine having a rotor, and motor vehicle having an electric machine

A rotor for an electric machine, comprising:

• a rotor main body which has at least two poles between which, in a circumferential direction of the rotor, is disposed at least one pole gap;
• a rotor shaft coupled in a rotationally fixed manner to the rotor main body;
• and
• a support device comprising a covering body and an annular body, which annular body is different from the covering body, wherein:
• the covering body is configured for covering at least regions of an end side of the rotor main body;
• the annular body is braced in a direction of radial extent of the rotor both in relation to the rotor main body and in relation to the covering body;
• the covering body has a through opening;
• the rotor shaft at least in the regions is guided through the through opening;
• the covering body has an annular central region which circumferentially encircles the through opening, and at least two covering regions that in the direction of radial extent of the rotor protrude from the central region;
• a recess of the covering body in the circumferential direction of the rotor is disposed between the at least two covering regions;
• and
• one covering region of the at least two covering regions covers, in the direction of axial extent of the rotor, at least in regions in each case one of the poles.
