A machine component of an electric machine includes a metal base body and a sealing element, arranged on the base body, for thermally decoupling the machine component and a unit abutting it. The base body is manufactured by pressure die-casting. The sealing element is made from plastic and is connected to the base body in a form-fit manner during the pressure die-casting of the base body.

Machine component of an electric machine and method for production thereof

The invention relates to a stator () of an electrical machine (), the electrical machine () itself, and a manufacturing method. The stator () has a meandering cooling channel (), wherein the meandering cooling channel () is embedded in an element (), wherein the element () comprises a material which is influenced thermally so as to form a shape of the element (), wherein an iron-containing body (), for guiding a magnetic field of the stator, is embedded in the element ().

Electrical machine with a cooling channel and method for manufacturing the same

In order to connect an angle measuring device to a brushless direct-current motor, a coupling is used, the coupling halves () of which are each attached to the rotor () of the motor and/or the rotor () of the angle measuring device. Instead of using a coupling that is rotationally symmetrical at arbitrary angular positions as in the prior art, a coupling is used in which the coupling halves () can be connected to one another only in a finite number of relative angular positions. An adjustment must be made before the coupling halves () are attached to the respective rotors (). This allows all subsequent adjustment to be omitted, for example, even for maintenance work.

Method for mounting an angle measuring device on an electric motor

The production costs of electrical machines are to be reduced. To this end, it should be possible to use standard transmitters for different axis heights of the electrical machine. The invention therefore provides a transmitter cover for an electrical machine, having a pot-like hood () for mounting on the electrical machine and for covering a transmitter, wherein the hood () has a central axis. The transmitter cover also has a mounting ring () which engages on the hood () in an interlocking manner. As a result, the hood () is pressed against the electrical machine in the axial direction when the mounting ring () is fixed to the electrical machine. This can prevent fastening screws () colliding with other fastening screws on the motor, this possibly being the case when only the hood () is used to cover the transmitter.

The aim of the invention is to provide a fluid-cooled electric machine in a simple manner. To achieve this, a housing () is configured in two parts, in such a way that each housing part () comprises a bearing bracket () and said housing parts are designed () to form cooling channels once assembled.

Electric machine with improved water cooling system

The invention relates to an electric machine () comprising a stator () and a rotor. The stator () includes at least one winding system having a plurality of coils () wherein start and end of the corresponding coils () is fixed on an end face of the stator () by means of a circuit support () and contacted in such a manner as to obtain predeterminable connections of the coils ().
