Embodiment Construction

[0021] figure 1 A flat laminate 1 is shown in side view, consisting of a plurality of sheet metal sheets 2 arranged one behind the other, in figure 1 Only the frontmost panel sheet 2 of these panel sheets is seen in . The flat lamination 1 has teeth 3 arranged at a distance such that between the teeth 3 there are slots 4 for receiving a stator winding 5 . The stator winding 5 consists of a plurality of winding wires 6 which are surrounded by slot insulation 7 in the slots 4 and are thus electrically insulated from the metal sheet 2 .

[0022] exist figure 1 , the stator winding 5 has three winding extensions 8, when the flat laminations are bent into a cylindrical stator (as it is in image 3 shown in ), these winding extensions are placed in the figure 1 in the still partially empty slot 4 at the right end. exist Figure 4 The partial view of FIG. 1 shows enlarged the region of the rounded stator 9 in which the winding overhangs 8 are inserted into the corresponding slo...

Abstract

The invention relates to an insulating element for the stator winding (5) of an electric machine, in the case of which electric machine the stator (9) is produced from a flat core (1) having a stator winding (5) lying therein and having winding wires (6) protruding from the flat core (1), which winding wires form at least one winding projection (8), wherein the insulating element (14) is an insulating clip (17-19) that can be placed onto the winding wires (6) of a winding projection (8) that protrude from the flat core (1) and that has a substantially U-shaped cross-section and elastic side legs (15, 16), and, in the relaxed state, the insulating clip (17-19) has an opening width at the free end of the lateral legs (15, 16) of the insulating clip that is smaller than the thickness of a winding projection (8) to be inserted between the legs (15, 16).

Description

technical field [0001] The invention relates to an insulating element for a stator winding of an electric machine according to the preamble of claim 1 and an electric machine according to claim 9 . Background technique [0002] In order to manufacture an electric machine that can be used as a generator or as an electric motor, the stator of the electric machine can be formed from flat laminations by bending them into circles. This method of production can be referred to as the flat lamination process, in which the windings of the stator, initially in the form of flat lamination laminations, are inserted into slots formed between the teeth. The flat laminations equipped with the stator windings are then rounded, wherein the protrusions present on one side of the flat laminations Engage in grooves, which are located on the opposite side of the flat lamination. [0003] The overhangs of the stator winding that first protrude on one side of the flat laminations are subjected ...
