摘要： A stator for an electric machine includes a laminated core having grooves evenly distributed in the circumferential direction around a longitudinal axis and continuously extending in a longitudinal direction of the core. Each groove receives at least two electric conductors having a substantially rectangular cross-section that are insulated against each other and against the core by at least one insulation layer coating in the radial direction and the circumferential direction as well as in the longitudinal direction at least over a stator height of the stator. The at least one insulation layer includes a thermoplastic high-performance polymer continuously closed in the circumferential direction and the radial direction and preferably directly extruded on the electric conductor. The insulation layer, at least in the circumferential direction, has a total circumferential layer thickness at least 1.5 to 3, preferably 1.8 to 2.2 times a total radial layer thickness of the respective electric conductor.

摘要： The invention relates to a method for provided shaped rods, which are intended for the use in electric windings of electric machines. The invention comprises providing conductor wire (11); positioning the conductor wire (11) and a bending axis (26) for the conductor wire relative to one another, such that the longitudinal axis (18) of the conductor wire (11) and the bending axis (26) run at an oblique angle relative to one another; holding, gripping, or supporting the conductor wire (11) in a first and second section (20, 21) of the conductor wire (11); and carrying out a swivel bending or folding movement (30) between the first and second section (20, 21) of the conductor wire (11) about the bending axis (26). Thereby, a simultaneous forming of a combined torsional and also curved section (17, 19) in the conductor wire (11) and also a lateral offset (16) between the first and second section (20, 21) of the conductor wire (11) is made possible. Moreover, a correspondingly shaped shaped rod is indicated.

摘要： A stator for an electrical machine includes an essentially hollow-cylindrical stator core with receiving grooves. Each receiving groove is bounded at least by opposing groove side walls and by a groove base surface. In each receiving groove are electrical conductor rods with a rectangular cross-section, which form a stator winding by predefined electrical connections. At least one structurally-independent electrical insulation layer is in each receiving groove for electrically insulating conductor rods from one another or from the stator core. A subset of the conductor rods in each receiving groove is wrapped by the insulation layer which is double-layered between at least one of the side surface of the wrapped subset and the nearest assigned groove side wall or the nearest assigned receiving groove side walls. Compared to the further electrical conductor rods in this receiving groove, this wrapped subset is assigned nearest to the groove base surface of this receiving groove.

摘要： The invention relates to a stator (1) for an electric machine, comprising an essentially hollow-cylindrical laminated core (2) with multiple receiving grooves (4) which are arranged distributed. Multiple electric conductor sections (La, Lb) per receiving groove (4) formed by forming rods form a stator winding (14) with at least two part-windings (TWa, TWb). The at least two electric part-windings (TWa, TWb) are respectively formed by at least one first and one second electrically series-connected winding segment (WSa, WSb), wherein conductor sections (La, Lb) of the first winding segment (WSa) are electrically interconnected by means of first and second electric connecting sections (VB a, VBb) such that a helical current path (17a) is defined along a first radial direction (18a) to the longitudinal axis (3) of the laminated core (2) and conductor sections (La, Lb) of the second winding segment (WSb) are electrically interconnected by means of first and second electric connecting sections (VB a, VBb) such that a second helical current path (17b) is defined along an opposite, second radial direction (18b) to the longitudinal axis (3) of the laminated core (2).
