摘要： A winding overhang (20) configured for supporting windings of an electric motor (40) comprise a cylindrical wall (22) extending around a center axis (A). The cylindrical wall (22) includes a plurality of grooves (28a-28e) formed along the circumference (37, 38) of the cylindrical wall (22), each groove (28a-28e) having a constant width (W) along the circumference (37, 38); and a plurality of openings (26) having different heights (H1, H2, H3, H4, H5). Each opening (26) extends from an end surface (36) of cylindrical wall (22) and allows a wire (30a-30c) to pass between an outer area (34) outside the cylindrical wall (22) and an inner space (32) defined by the cylindrical wall (22).
