Embodiment Construction

[0041] figure 1Firstly, a stator element 100 for an electric machine, for example in the form of an electric motor, is shown by way of example. The stator element 100 has undergone the aforementioned assembly process, which has been outlined by way of example with the aid of a structural breakdown: pre-positioning, assembly preparation and assembly operations. As a result, a plurality of copper rods 30 can be inserted into the circumferentially arranged receiving slots 102 of the stator element 100 . It can now be seen that in the present case four copper rods 30 are inserted into the receiving groove 102 via one of their foot parts 32 , 34 . In each receiving groove 102, the leg portions 32, 34 are arranged side by side in the radial direction. Starting from the foot portion 32 , 34 of the receiving groove 102 , the other foot portion 34 , 32 of each copper rod 30 is alternately inserted into the corresponding receiving groove 102 in opposite circumferential directions. A ...

Abstract

The invention relates to a positioning device for circumferentially positioning a plurality of copper rods having a substantially U-shaped profile with a first leg portion and a second leg portion around a central axis M describing an axial direction.

Description

technical field [0001] The invention relates to a positioning device for circumferentially positioning a plurality of copper rods around a central axis M describing the axial direction, wherein the copper rods are of substantially U-shaped profile with a first leg portion and a second leg portion. Background technique [0002] In the manufacture of electric machines, such as electric motors or generators, it is a problem to simplify the assembly process while improving the quality parameters during the assembly process. The distinction between stator elements or rotor elements produced by winding technology or hairpin technology should be made here. Issuing technology offers the possibility of increasing the power density of electric motors intended for use in motor vehicles. In hairpin technology, curved copper rods, called hairpins in particular due to their shape, are inserted into axially extending receiving slots of the stator or rotor element, which are arranged on th...
