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.

Abstract: An insulation system for a stator of an electric motor, in particular for an electric motor of an electrical compressor, wherein the stator has multiple coil carriers which point radially inwards from a stator inner side and have inner flanges spaced apart on the head side, said inner flanges radially delimiting coils wound onto the coil carriers with electrical conductors, wherein the insulation system comprises insulator elements which are each held at their foot end by holding grooves formed on the stator inner side in the axial direction between axial end sides of the stator and are positioned pointing radially inwards between adjacent coils with their head ends between opposing flanks of adjacent inner flanges, wherein an electrically insulating substance is introduced in contact regions between the insulator elements and the holding grooves and/or between the insulator elements and the inner flanges of the coil carriers.

Abstract: The invention relating to a stator assembly (1) in an electrically multi-phase activated drive motor with a stator (3) comprising several stator teeth (2), wherein the stator teeth (2) comprise a tooth surface (5) directed toward a pivotably supported rotor (4), has as its objective specifying a stator assembly [1] that enables a reduction of the noise and vibrations occurring during operation of a drive motor. This task is resolved thereby that at least one stator tooth (2) for each motor phase of the drive motor is implemented such that on the tooth surface (5) of this stator tooth (2) are disposed at least one first planar-formed surface region (6) and maximally one second surface region (7) comprising a curvature.
