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.
摘要:
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 atomised 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 atomised 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.

摘要:
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.
