Title: WINDING OF AN ELECTRIC MACHINE HAVING INCREASED WINDING FACTOR
Abstract:
The invention relates to a device (100) comprising: at least one stator (110) having two radially symmetrical cover surfaces (120), wherein the stator (110) has at least two grooves (130) which each extend in the axial or transverse-axial direction from a cover surface (120) to the opposite cover surface (120) through the entire stator (110) and into the stator (110) in the radial direction, and which have an internal end surface (330); and at least one flat wire winding (140) formed by at least two coil windings (220) by means of a flat wire (210). Wherein these (220) are arranged without joining points and stacked on top of one another in such a way that the respective flat wire (210) runs substantially parallel to the respective neighbouring flat wire (210) and is formed such that they are substantially adjacent to one another. Wherein the flat wire winding (140) is at least partially introduced inside the grooves (130) in such a way that the first coil winding (220) runs substantially adjacent to the end surface (330) of the respective groove (130), and at least one region of the flat wire winding (140), which is arranged outside of the grooves (130), is arranged along a groove-free region (180) and runs substantially parallel to the respective cover surface (120).
