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 pluralityof 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 the 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).
一种配置成用于支承电动马达(40)的绕组的绕组悬突部(20)包括围绕中心轴线(A)延伸的圆柱形壁(22)。圆柱形壁(22)包括:多个凹槽(28a‑28e),其沿着圆柱形壁(22)的圆周(37、38)形成,每个凹槽(28a‑28e)具有沿着圆周(37、38)恒定的宽度(W);以及多个开口(26),其具有不同的高度(H、H、H、H、H)。每个开口(26)从圆柱形壁(22)的端部表面(36)延伸,且允许线(30a‑30c)在圆柱形壁(22)外部的外部区域(34)与由圆柱形壁(22)限定的内部空间(32)之间经过。
