Abstract: An electrical machine with oil cooling includes a rotor and a stator sealed against the rotor, located in a space wetted with oil and arranged within a housing of the electrical machine. The stator is formed of stator laminations having radially running winding grooves. The stator laminations have a seal injection molded along their inner radii and the winding grooves are coated with an insulation from the same injection molding material.

Abstract: A power converter having a busbar device includes at least one ferrite core filter and at least two busbars, which are spaced from one another in an electrically insulated manner. The busbars may have different electric potentials, so that the busbars can carry an electric current appropriate for a bar cross-sectional area. The busbars are guided at least once through at least one feed-through opening of the ferrite core filter. The busbars are one piece in each case, and are reshaped by a bend formed in a passage area of the feed-through opening, and a passage cross-sectional area of the busbars in the passage area is at least the same size as the bar cross-sectional area, so that the busbars can carry the same electric current along the run of the busbars.

Abstract: A method for producing an inverter incldues installing at least one filter assembly and one assembly for intermediate circuit capacitorsin an inverter housing on busbars. The individual components of the filter assembly and the assembly of the intermediate circuit capacitors are arranged optimally with respect to one another. The filter assembly and the assembly for intermediate circuit capacitors are jointly fastened in the inverter housing or a partial housing within the inverter housing using a potting compound and are thermally connected.

Abstract: The invention relates to a power converter having a busbar device, a method for producing a busbar device and a busbar device for carrying and distributing electric currents, having at least one ferrite core filter and having at least two busbars, which are spaced from one another in an electrically insulated manner, it being possible for the busbars to have different electric potentials, so that the busbars can carry an electric current appropriate for a bar cross-sectional area, and the busbars being guided at least once through at least one feed-through opening of the ferrite core filter.
