Abstract: A stator of an electric machine, such as for a drivetrain of a motor vehicle is provided. The stator includes a hollow-cylindrical stator body formed by a plurality of bundled stator laminations and a plurality of stator slots. The stator slots have a cross section with a U-shaped contour with two substantially parallel side walls, a slot base, and a slot opening lying radially opposite the slot base. A plurality of electrical conductors have a substantially rectangular conductor cross section and are arranged radially above one another in each stator slot forming a stator winding. The slot opening has a circumferential width smaller than a circumferential width of the electrical conductor radially closest to the slot opening. The electrical conductor radially closest to the slot opening is plastically deformed in the circumferential direction by being press-fit in the radial direction towards the slot base.

Abstract: A contactless energy transmission device for a rotor of an electric machine is disclosed. The device includes a housing part, which can be coupled in a rotationally rigid manner to a housing of the electric machine, and an inductive transformer which has an energizable primary coil and a secondary coil that is arranged at a distance thereto and can be electrically coupled to a winding of the rotor a roller bearing, by means of which a rotor shaft is rotatably mounted relative to the housing part, wherein the primary coil is positioned on the housing part in a rotationally rigid manner relative thereto, and the roller bearing is arranged within the housing part such that the primary coil and the roller bearing are arranged coaxially, and the secondary coil is arranged within a transformer housing.

Abstract: At least two pole shoe segments are associated with a stator tooth in the stator of an axial flux machine; the pole shoe segments are spaced apart from each other. In particular, each pole shoe segment can cover both a part of a stator tooth and a part of a groove for stator windings.

Abstract: The invention relates to an electric machine comprising either a circular-ring-cylindrical stator and a circular-cylindrical rotor which is arranged rotatably inside the stator, or a circular-cylindrical stator and a circular-ring-cylindrical rotor, which is arranged rotatably outside the stator, there being an air gap formed between the stator and the rotor. The rotor comprises a magnetically conductive rotor body and at least one pair of magnets arranged adjacently within the rotor body, wherein magnet axes leaving identical poles of the magnets of the magnet pair intersect one another on the side of the magnets of the magnet pair facing the stator. The rotor body has at least one recess in a region extending in the circumferential direction and radial direction of the rotor and defined by the magnet pair.
