Abstract: The invention relates to a slot seal for an electric machine (13) comprising at least one slot (4) provided with a slot opening for arranging an electric conductor arrangement (6), wherein said slot sealing comprises, on the face thereof oriented towards the conductor arrangement (6), at least one bulge (1) which is oriented to the electric conductor arrangement (6), extends along at least one part of the slot seal length and is selected in such a way that it is elastic or at least deformable and the ends thereof are fixedly interconnected, at least partially, by a cover (2).

Abstract: The coating method is for application to the coating of an end winding (3) of an electric motor (4), whereby the end winding (3) comprises several conductor arrangements (2) for coating. The coating material for application is atomized by means of a spray device (1). An electrostatic potential difference (U) is applied between the spray device (1) and the conductor arrangements (2) for spraying, such that atomized particles of the coating material are transported along the forming electrical field lines in the direction of the conductor arrangements (2) of the end windings (3) for coating.

Abstract: The invention relates to a protective layer (13) for a winding head of an electric machine. Said protective layer consists of a moisture-repellent material that comprises a nanostructured surface (8) once it has been applied to the winding head, resulting in a water contact angle of at least 120 DEG.

Abstract: Mica-reinforced insulating hose (1) for insulating electrical contact connections with a support hose (2), which has a mica tape (4) surrounding it with one or more layers.

Abstract: The invention relates to a drive unit for a vehicle and an electric motor that is suitable therefore, comprising a rotor and a stator (1) which is formed by a sheet metal pack (2) and is provided with grooves, at least one winding (3a) being disposed in said grooves (3). The electric motor is penetrated by cooling air. In order to keep production costs low and obtain thermal class 200, the winding (3a) is formed from round wires (7) that are provided with an insulation (12) while the coil heads (4) are embedded in a temperature-resistant elastic material (4a) so as to be protected against external influences.

Abstract: An electric machine includes a laminated stator core having slots for receiving a stator winding, and a corona shield for insulating the stator winding. The corona shield includes a substrate; and a coating applied on the substrate, wherein the substrate and the coating are made entirely of inorganic material.

Abstract: A corona shield for an electrical machine includes a substrate with a coating or a fabric or non-woven fabric made of filaments which are coated, wherein the coating contains electrically conductive inorganic material.

Abstract: A corona shield for an electrical machine includes a non-woven fabric of fibers or a fabric of threads, wherein the fibers or threads contain electrically conductive inorganic material.
