Embodiment Construction

[0045] figure 1 A starting position at the beginning of a method for manufacturing a coil winding 70 for a stator of an electric motor (not shown) is shown. For this purpose, in the exemplary embodiment shown, the winding device 10 is in the standby state, said winding device having a winding head 12 with a wire handling device 14 comprising a wire pulling device 16 , three wire holding devices 18, 20, 22 (see also Figure 5 ) and winding head forming device 24. The rolling device 10 interacts with a rolling form 26 realized as a flat form, ie having a strip-like shape. The section of winding formwork 26 is in figure 1 It is clear in the upper part a of the illustration, from which the edge region 27 of the coil formwork 26 (which tapers towards the side) and the radius of the side itself can be seen. According to the length of the coil winding 70 to be manufactured and according to the precise configuration of the method to determine the length of the winding template 2...

Abstract

The method according to the invention is used to produce a coil winding (70) which can be inserted into the grooves of a stator or rotor of an electric machine. While using a winding template (26) anda wire handling device (14), the invention proposes carrying out a displacement process between a first and a second holding region (34, 36) even before the wires (32) are initially wound onto the winding template (26) in order to produce an inclined wire section (40) which is subsequently shaped into winding heads (42) by means of a rotating / winding process. The novel method offers the advantagethat all of the wires (32) of a coil winding (70) can be processed simultaneously using a comparably simple winding device (110). The projection of the winding heads (42) over the stator can also beminimized.

Description

technical field [0001] The invention relates to a method for manufacturing a coil winding for insertion into a radial opening groove of a stator or rotor of an electrical machine, wherein said coil winding consists of a plurality of wires wound together and Bend several times in opposite directions so that the wire legs parallel to each other and intended to fill the grooves are connected by a roof-like winding head which protrudes beyond the rotor or stator at the front end, where a flat and Rotating winding template and wire manipulator. [0002] The method is also particularly suitable for using wires which are substantially rectangular in cross-section and which are preferred with regard to an optimum filling level in the grooves of the stator. Conventional methods for round wire winding are not suitable for this wire section. Background technique [0003] The method is first used to manufacture so-called distributed wave windings, which can then be inserted into groov...
