  • Publication number: 20200366149
    Abstract: An electric motor having has a rotor and a stator with a stator core as well as an insulation assembly, which extend along a common longitudinal axis from a first end face to a second end face of the stator. The stator core is formed with bars arranged uniformly distributed on the circumference to accommodate conducting wires wound into coils. The insulation assembly has a first insulation element, second insulation elements, and a third insulation element. The first insulation element is arranged between conducting wires and the stator core; a respective second insulation element is arranged in an intermediate space formed between coils arranged to fit closely to one another; and the third insulation element is arranged on an inner side of the stator, the inner side pointing inward in the radial direction, in a manner so as to seal the inner side.

  • Publication number: 20200313502
    Abstract: A device for driving a compressor of a vaporous fluid, in particular an electric motor. The device includes a rotor and a stator having a stator core, arranged extending along a common longitudinal axis. A carrier element, which is formed having at least one receptacle element for a plug housing for accommodating at least one plug connector and also at least one clamping element for fixing the carrier element on the stator core as a coherent unit and one-piece component, is arranged pressing against a first end face of the stator aligned in an axial direction. The at least one clamping element is arranged on a side of the carrier element aligned in the axial direction and facing toward the stator core and having an inner side pressing against an outer side of an outer wall of the stator core, centering the carrier element on the stator core.

  • Publication number: 20200018300
    Abstract: The invention relates to a device for driving a compressor of a vaporous fluid, particularly an electric motor. The device has a rotor and a stator, which are extended along a common longitudinal axis, as well as an insulation element. The insulation element is designed as a single part and connected with a stator core of the stator in a form-fitting manner such that the stator core and the insulation element form an integral and single-part component of the stator. The invention further relates to a method for producing a stator of the device, particularly the stator core with the insulation element.

  • Publication number: 20190390679
    Abstract: Sealing arrangement for guiding an electrical connection through a wall of a housing for a device for driving a compressor having an electrically conducting connecting element, guided through a conical passage aperture of the housing, which at least regionally is fully enclosed over the entire circumference by a sealing element. Sealing element is formed as a hollow truncated cone and disposed between a conical sealing facing of the connecting element and a boundary surface of the passage aperture sealing the connecting element against the housing. The connecting element is disposed having been guided through a connection passage of a receiving member for receiving a plug housing with a wall into the plug housing. A device for driving a compressor of a gaseous fluid with the sealing arrangement and a method for assembling the device and use of the device are disclosed.

  • Publication number: 20190393750
    Abstract: A device, in particular to an electric motor, for driving a compressor of a gaseous fluid. The device comprises a rotor and a stator disposed such that they extend along a common longitudinal axis. The stator comprises connection leads developed as segments of conductor wires of coils. In a region of at least one end side, oriented in an axial direction, of the stator a cover element is disposed which is developed in the form of an axially oriented hollow cylinder with an inner surface and an outer surface. The cover element herein is with the inner surface in contact on an insulation element disposed on the stator and comprising a cylindrical wall. Between an outer side of the wall of insulation element and the inner surface of the cover element are disposed at least segments of the connection leads of the conductor wires.
