Abstract
Stator for an electric machine has a number N of phases (U, V, W), a number P of pole pairs and a number of holes q, wherein N≥3 and P≥2 and q=3. The stator includes a stator core having a plurality of slots and a plurality of shaped conductors, which are arranged in the slots so as to be radially layered in a first to Lth layer, wherein L=6. The shaped conductors of each phase form a first path and second path, which can be or are interconnected in series or in parallel with each other and are arranged in P first winding zones and P second winding zones, wherein the first and second winding zones alternate in the circumferential direction. The shaped conductors of a respective path are interconnected to form a series connection by connectors.

A stator for an electric machine, wherein
- the stator has a number N of phases, a number P of pole pairs and a number of holes q, wherein N≥3 and P≥2 and q=3, wherein
- the stator comprises a stator core having a plurality slots and a plurality shaped conductors, which are arranged in the slots so as to be radially layered in a first to Lth layer, wherein L=6 and the layers are numbered in their order in the radial direction, wherein
- the shaped conductors of each phase form a first path and second path, which can be or are interconnected in series or in parallel with each other and are arranged in P first winding zones and P second winding zones, wherein the first and second winding zones alternate in the circumferential direction and each winding zone extends over the L layers, wherein a first orientation and a second orientation which is opposed to the first orientation of the circumferential directions are defined, wherein
- the shaped conductors of a respective path are interconnected to form a series connection having a first outer shaped conductor in terms of the series connection and a second outer shaped conductor in terms of the series connection, by connectors, which connect shaped conductors in adjacent winding zones of the same phase in an alternating manner at a first end side and a second end side opposite the first end side of the stator core, wherein
- the first and second layer of a respective winding zone are offset with respect to the third and fourth layer of the respective winding zone by one slot in the circumferential direction, wherein
- the paths each form a combined lap and wave winding.
