Embodiment Construction

[0029] figure 1 The machine assembly 1 of the electric machine 100 is shown in cross section (see figure 2 ). The machine component 1 is located in an injection mold 3 , which is used to manufacture the machine component 1 and consists of a first mold part 5 and a second mold part 7 . here, in figure 1 Correspondingly only the machine component 1 and the foot membrane parts 5 , 7 are shown in section.

[0030] The machine component 1 comprises a metal base body 9 and a seal 11 made of plastic arranged at the base body 9 for connecting the machine component 1 to a component 112 abutting against it (see figure 2 ) thermal decoupling. The machine component 1 is, for example, a bearing endshield of an electric machine 100 and the seal 11 is designed, for example, as a substantially disk-shaped seal 11 for thermally decoupling the machine component 1 from the generator housing of the measurement value generator abutting against it.

[0031] Preferably, the seal 11 is made of...

Abstract

The invention relates to a machine component (1) of an electric machine. The machine component (1) comprises a metallic base body (9) and a seal (11) arranged on the base body (9) which serves for thermal decoupling of the machine component (1) and components placed thereon. The base body (9) is produced by die casting. The seal ( 11 ) is made of plastic and is positively connected to the base body ( 9 ) during injection molding of the base body ( 9 ).

Description

technical field [0001] The invention relates to a machine component of an electric machine with a metallic base body and a seal arranged on the base body. Furthermore, the invention relates to a method for producing a machine component of this type. Furthermore, the invention also relates to an electric machine. Background technique [0002] Active parts of electric motors, such as those of servo motors, are often very hot during operation. Further components of the electric machine, in particular the measured value generator, must not be exposed to temperatures above a defined maximum temperature, since they would be damaged or destroyed. Therefore, active components are often required to be thermally decoupled from further components of the electric machine. In particular, the mostly metallic housing of the electric motor and the measured value generator must often be thermally decoupled from one another. For the thermal decoupling of such housings, for example, spacer...
