Abstract (en)

[origin: EP2474986A1] The winding (10) has two hollow-cylindrical winding modules (12, 14) provided with electrical conductors (18, 20) and axially arranged around a common winding axis (16). An electrical insulation layer (22) encloses the winding modules, and includes radial recesses (28, 30) or a ring-like radial projection (32) protruded transverse to the winding axis at a radial outer surface (24). The recesses are arranged between the winding modules. The winding is defined at axial front surfaces of front plates (38, 40). A flexible profile strip is partially wrapped by an insulation material.
