Abstract
Official abstract text for this publication.
A rotor, in particular of an electrical machine, has a base body and at least one metallic end plate which is mounted on the base body. The base body and the at least one end plate have a continuous layer which is injection molded.
First claim
Opening claim text (preview).
What is claimed is: 1. A rotor of an electric machine, comprising: a main body; and at least one metallic end disk, which is arranged at an end side on the main body, wherein the main body and the at least one end disk are provided with a continuous layer, the continuous layer is injection molded, the continuous layer is composed of plastic, the at least one end disk is composed of aluminum, the at least one end disk is arranged directly on the main body, the at least one end disk comprises retaining sections that extend along an axis of rotation of the rotor and are configured for radial support of at least one conductor element, the rotor is of multi-part form, and the continuous layer forms a locating and/or retaining device in a connecting region of two rotor parts within the main body, such that a first portion of the continuous layer protrudes from a first rotor part of the two rotor parts and interlocks with a second portion of the continuous layer formed in a second rotor part of the two rotor parts. 2. The rotor according to claim 1 , wherein the plastic is a thermoplastic. 3. The rotor according to claim 1 , wherein the plastic is a thermoset. 4. The rotor according to claim 1 , wherein the continuous layer is composed of plastic. 5. The rotor according to claim 1 , wherein the continuous layer forms grooves configured for arranging conductor elements. 6. The rotor according to claim 1 , wherein the continuous layer forms at least one arranging section for a slot-closing wedge. 7. The rotor according to claim 1 , wherein the continuous layer has at least one guide element for guiding a conductor element. 8. The rotor according to claim 1 , wherein at least one electric component is cast into the continuous layer. 9. The rotor according to claim 1 , wherein the rotor is of two-part form. 10. An electric machine, comprising a rotor according to claim 1 . 11. A method for producing an electric machine, comprising: providing a rotor having a main body, which extends along an axis of rotation; arranging a metallic end disk at a face side at at least one end of the main body; and overmolding the main body and the at least one end disk with a material to produce a continuous layer connecting the main body and the at least one end disk, wherein: the continuous layer is injection molded, the continuous layer is composed of plastic, the at least one end disk is composed of aluminum, the at least one end disk is arranged directly on the main body, the at least one end disk comprises retaining sections that extend along an axis of rotation of the rotor and are configured for radial support of at least one conductor element, the rotor is of multi-part form, and the continuous layer forms a locating and/or retaining device in a connecting region of two rotor parts within the main body, such that a first portion of the continuous layer protrudes from a first rotor part of the two rotor parts and interlocks with a second portion of the continuous layer formed in a second rotor part of the two rotor parts.
