Abstract: The present document relates to an electric drive unit, comprising: a stator configured to produce a stator magnetic field, at least a first rotor including first rotor windings, the first rotor windings for instance including multi-phase windings, and at least a first inverter electrically connected with the first rotor windings and configured to produce an electric current in the first rotor windings for producing a first rotor magnetic field. The stator magnetic field is configured to interact with the first rotor magnetic field to exert a torque on the first rotor. The present document further relates to a method of operating the electric drive unit.

Abstract: Embodiments for a torque vectoring unit for an electric vehicle are provided herein. In an example, a torque vectoring unit includes an inner rotor, an outer rotor enclosing the inner rotor, and a stator enclosing the outer rotor, with the inner rotor, the outer rotor and the stator being concentrically arranged to one another. The inner rotor is drivingly connectable to a first wheel and the outer rotor is drivingly connectable to a second wheel, and the inner rotor and the outer rotor represent a first electric motor and the outer rotor and the stator represent a second electric motor.

Abstract: An electric motor and inverter assembly and a method of assembly therefor, the electric motor and inverter assembly having a motor housing portion, a DC bus bar for electrically connecting a DC power source to an inverter power module where the DC bus bar is mounted on the housing portion, and a cooling channel disposed in between the housing portion and the DC bus bar for cooling the DC bus bar.

Abstract: Disclosed herein are power conversion devices comprising power modules, capacitor modules, and support frames. The power modules may be operable to convert direct current (DC) electricity to alternating current (AC) electricity. The capacitor modules may be electrically connected to the power modules. The support frames may house the power modules and conductor plates, and the capacitor modules may be at least partially wound around exterior sides of the support frames. Such arrangements may advantageously take up less installation space and/or have better form factors than power conversion devices with cylindrical capacitors.

Abstract: An electric machine system is provided. The system includes a stack of a plurality of stator laminations with at least a portion of the plurality of stator laminations each including a plurality of holes that are arranged radially outward from a plurality of teeth, where the plurality of holes include a first set of holes, a second set of holes, and a third set of holes, where the first, second, and third sets of holes has a different profile and/or area, where the second set of holes are positioned radially inward from the third set of holes; and where a plurality of oil channels are formed by an alignment of holes in adjacent stator laminations in the portion of the plurality of stator laminations.

Abstract: A stack of laminations for a stator of an electric machine, wherein each lamination comprises a plurality of teeth, and a plurality of holes, wherein the laminations are aligned relatively to one other such that the teeth form winding spaces for receiving stator windings, and the holes form at least one axially extending cooling channel inside the stack, wherein adjacent holes of at least two adjacent laminations are geometrically different.
