Abstract

The invention relates to an arrangement of a stator segment (20) of an electrical machine. The arrangement comprises at least one group of three windings (31,32,33), each of the three windings (31,32,33) being shaped as a closed loop, the loop thus defining an inner area of the winding and an outer area with regard to the winding. Each winding comprises a straight first winding segment (34), a straight second winding segment (35) and a winding head, each first winding segment (34) is substantially parallel to each second winding segment (35). Each winding head comprises a winding head closure (36,37,38) with a winding head closure inner surface facing to the inner area, and a substantially rectangular winding head closure outer surface facing to the outer area. At least two of the three winding head closure outer surfaces are substantially parallel to each other, and the three windings (31,32,33) are arranged and prepared to be embedded in the winding slots such that each of the three winding heads is shifted with regard to the other two winding heads. The invention also refers to a method of manufacturing such an arrangement, and to a method of manufacturing a stator segment (20) of an electrical machine, the stator segment (20) comprising such an arrangement as described above.
