Embodiment Construction

[0035] figure 1 A cross-sectional view of a first exemplary embodiment of a rotor 1 is shown.

[0036] The rotor 1 has a rotor core 2 with a plurality of rotor legs 3 extending radially outward, which can be formed as a plate pack. In this exemplary embodiment, eight rotor legs 3 are provided as an example. Furthermore, the rotor 1 has a number of field windings 4 corresponding to the number of rotor legs 3 , each field winding being wound around a rotor leg 3 .

[0037]Furthermore, the rotor 1 comprises a pot-like end cap 5 which covers the end face of the field winding 4 and has a passage opening 6 for the shaft 7 . To this end, the end cap 5 can have a base surface 8 in which the passage opening 6 is formed, and an axially inwardly extending collar 9 arranged on the base surface 8 . It extends on the radially outer edge and in the circumferential direction completely around the axis of rotation 10 of the rotor 1 .

Abstract

A rotor (1) for an electric machine (101), comprising: a rotor core (2) having a plurality of rotor legs (3) extending radially outward; a plurality of field windings (4) corresponding to the number of the rotor legs (3), each field winding being wound around one of the plurality of rotor legs (3); and a pot-shaped end cap (5) covering an end face of the field winding (4) and having a passage opening (6) for a shaft (7), the field winding (4) and the end cap (5) delimiting intermediate spaces (16), in each of which a castable (17) is arranged.

Description

technical field [0001] The invention relates to a rotor for an electric machine. Furthermore, the invention relates to an electric machine for a vehicle and a method for producing a rotor for an electric machine. Background technique [0002] DE 10 2004 062 162 A1 discloses an electrical machine with a salient-pole generator rotor with field windings. A salient pole generator rotor has poles with axially extending pole gaps between them. [0003] The rotor has rotor legs around which field windings are wound, and the rotor is subjected to considerable radial forces, such as centrifugal forces, during operation. These radial forces pull in particular the winding ends of the field winding. In order to ensure that the rotor is not limited by these radial forces during operation, it has been proposed to have the rotor completely grouted, or to install additional parts, such as reinforcing rings or fixings with bolts and tie rods. However, such measures are costly, cumbersome...
