Abstract

The invention provides a method for winding a stator (10), as well as a stator and an electric machine with such a stator. The stator (10) comprises radial stator teeth (14) and grooves (12) between the stator teeth; a first sub-coil (18) is wound around a first stator tooth (14) by using needle type winding; a connecting wire (31) is wound via a radially-movable slider (56) close to a first axial end face (50) of the stator (10) to form a second sub-coil (18) of a second stator tooth (14); then the slider (56) is removed; the connecting wire (31) is fixed in at least one clamping element (48) of the stator (10).

Description

technical field

[0001] The present invention relates to a method for winding a stator as claimed in the independent claims, as well as to a stator and an electric machine comprising such a stator. Background technique

[0002] From DE 10 2012 224 153 A1, a stator for an electric machine is known, in which insulating laminations and connecting disks are arranged axially on the lamination stack. The stator is wound, for example, with needle-coils, wherein the individual sub-coils are connected to one another on the outer circumference of the connection disk by means of connecting lines. The entire winding is wound continuously in one piece with a single winding wire.

[0003] For safety-critical applications of electric machines, eg in power steering machines, the inherent safety of such electrical windings is still under discussion. There is the risk that, for example, if the insulating varnish of the winding wire is damaged, a short circuit of the winding can occur, which ...
