Embodiment Construction

[0055] First of all, it should be confirmed that, in the different described embodiments, the same components have the same reference numerals or the same component names, and the disclosure contained in the entire specification can be reasonably transferred to the same reference numerals or the same component names. same parts. The position descriptions used in the description, such as eg top, bottom, side, etc., refer to the current description and the figures shown and can be appropriately transferred to the new position in the event of a change of position.

[0056] figure 1 A possible configuration for forming the stator 1 of an electric machine not shown in detail is shown. However, the following descriptions and descriptions can also be applied and implemented in a similar manner to a rotor for forming an electric machine. The following description refers only to the stator 1, but can also be applied to the rotor.

[0057] The assembly of the stator 1 and the various...

Abstract

The invention relates to a method for producing a semifinished product of a stator (1) or a rotor of an electrical machine, the method comprising the following method steps: providing a lamination stack (2) having a plurality of circumferential To the accommodating grooves (5) arranged in distribution; providing a plurality of conductor elements (3, 4); putting the conductor elements (3, 4) into at least individual accommodating grooves (5), placing the conductor elements (3 , 4) into the receiving groove (5) in this way, so that the conductor element protrusions (11, 12) of the conductor elements (3, 4) are axially removed from at least one axial end (7) of the lamination stack (2) , 8) protruding; radially (22) bending said conductor element protrusions (11, 12); circumferentially (16, 17) bending conductor element protrusions (11, 12) of conductor elements (3, 4) ).

Description

technical field [0001] The invention relates to a method for producing a semi-finished product of a stator or rotor of an electric machine and to a device for carrying out the method. Background technique [0002] DE 10 2015 217 922 A1 discloses a method for producing a stator in which one electrical conductor element for each layer of a double-layer winding is arranged in the slots of a laminated core. For this purpose, on the end side of the lamination stack, for one or two layers, during the positioning process, the normal tilting tool is Axially spliced ​​together with the axial conductor ends of some conductor elements and then relatively rotating the normal tilting tool with respect to the lamination stack, and by connecting the selective tilting tool with the axial conductors of the remaining conductor elements The ends are plugged together in the axial direction so that the conductor ends of all conductor elements of the layer are moved relative to each other in su...
