Zusammenfassung:The present invention describes a finger plate element (100) mountable to an axial end (401) of a stator (400) for an electric machine, in particular a wind turbine (1), the finger plate element (100) comprising a plurality of sheets (201, 301) forming a laminated stack (200, 300) having a fixation portion (110) which is formed for being fixable to a support structure (450) of the stator (400), and a winding accommodation portion (120) configured for accommodating windings (470) of the stator (400), wherein the fixing portion (110) extends in a radial direction (101) from the winding accommodation portion (120) to an inner radial end (161) of the laminated stack (200, 300), and wherein the winding accommodation portion (120) is coupleable to a lamination stack (430) of the stator (400) for being in magnetic interaction with the lamination stack (430) of the stator (400). Furthermore, a stator (400), a wind turbine (1), and a method for manufacturing a finger plate element (100) are described.
