Abstract: The invention relates to a stator (1) of an electrical machine (10), the electrical machine (10) itself, and a manufacturing method. The stator (1) has a meandering cooling channel (18), wherein the meandering cooling channel (18) is embedded in an element (22), wherein the element (22) comprises a material which is influenced thermally so as to form a shape of the element (22), wherein an iron-containing body (3), for guiding a magnetic field of the stator, is embedded in the element (22).

Abstract: In order to connect an angle measuring device to a brushless direct-current motor, a coupling is used, the coupling halves (10, 28) of which are each attached to the rotor (46) of the motor and/or the rotor (42) 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 (10, 28) can be connected to one another only in a finite number of relative angular positions. An adjustment must be made before the coupling halves (10, 28) are attached to the respective rotors (46, 52). This allows all subsequent adjustment to be omitted, for example, even for maintenance work.

Abstract: 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 (11) for mounting on the electrical machine and for covering a transmitter, wherein the hood (11) has a central axis. The transmitter cover also has a mounting ring (10) which engages on the hood (11) in an interlocking manner. As a result, the hood (11) is pressed against the electrical machine in the axial direction when the mounting ring (10) is fixed to the electrical machine. This can prevent fastening screws (13) colliding with other fastening screws on the motor, this possibly being the case when only the hood (11) is used to cover the transmitter.

Abstract: The aim of the invention is to provide a fluid-cooled electric machine in a simple manner. To achieve this, a housing (1) is configured in two parts, in such a way that each housing part (2, 3) comprises a bearing bracket (4, 5) and said housing parts are designed (2, 3) to form cooling channels once assembled.

Abstract: The invention relates to an electric machine (1) comprising a stator (21) and a rotor. The stator (21) includes at least one winding system having a plurality of coils (2) wherein start and end of the corresponding coils (21) is fixed on an end face of the stator (21) by means of a circuit support (7) and contacted in such a manner as to obtain predeterminable connections of the coils (2).

Abstract: The invention relates to a rotor (10) for an electric motor, wherein at least two permanent magnets (18 and 18?) are arranged behind each other in the axial direction (with respect to an axis of rotation (16) of the rotor (10)), instead of a single continuous permanent magnet. Said permanent magnets are separated from each other by an electrically non-conductive separator (20). Thus eddy current losses are reduced and heating of the permanent magnets, caused by the eddy current losses, is greatly prevented. The separator (20) contributes also to increased positioning accuracy of the permanent magnets.

Abstract: A hood-shaped cover for an electronic device includes a device-proximal bottom side and a device-distal side, and a cable guide for routing a connecting cable of the electronic device such that a plug-in connector of the connecting cable is connectable to the electronic device. The cable guide includes in the device-proximal bottom side an opening which is configured to extend helically toward the device-distal side into a passageway for encompassing the connecting cable and terminates in a cable outlet disposed tangentially to the device-distal side of the bottom.

Abstract: The invention relates to a side channel compressor having an impeller (2) which is arranged rotatably in the housing (1) of the compressor and has a carrying ring (3) which is provided with feed vanes (4) and, at least on one side, projects axially beyond a hub part (5) which bears the carrying ring and connects it to a drive shaft, in the case of which compressor, in the region of the carrying ring (3), a sealing ring (6), which butts against the inner circumference of the axially projecting part of the carrying ring (3) and seals the gap (13) present between the impeller (2) and the housing (1), is retained, by means of a retaining ring (8), in a state clamped against an abutment surface provided on the housing (1). The installation is simplified in that a centering border (10) which aligns the sealing ring (6) is provided on the abutment surface.
