Stator with winding slots sealed by foaming sealing material, electric motor with stator and sealing with slot direct cooling by (partially) coated insulation components with foaming material

Abstract

The invention relates to a stator (1) for an electric motor, comprising a stator body (2) having winding slots (3) for receiving a winding (4), and at least one cover slide (6) for closing at least one of the winding slots (3). A planar insulator (7) is arranged in the winding slot (3) to separate the winding (4) from the stator body (2). A sealing material (9) that foams upon heating is present exclusively at at least one edge region (11) of the planar insulator (7), and / or such a sealing material (9) that foams upon heating is present on the cover slide (6). The invention also relates to an electric motor with a rotor arranged within such a stator (1).
