Abstract
Stator, which has N≥3 phases, P≥2 pole pairs and a hole count q=2 and also includes a stator core with a plurality of slots and a plurality of shaped conductors. The shaped conductors form for each phase a first and a second path and are arranged in 2·P winding zones which are each subdivided into a first and a second sub-winding zone. The shaped conductors of a respective path are interconnected to form a series connection with a first end-shaped conductor and a second end-shaped conductor by connectors, which connect shaped conductors in adjacent winding zones of the same phase in an alternating manner at two axial face sides. The shaped conductors of a respective path form a first to third section of shaped conductors successively in the series connection. The first and third sections include the first and second end-shaped conductor respectively.
