Abstract: A rotor assembly for an electric machine has a rotor and magnets configured to form rotor poles that each have a central pole axis extending in a radial direction from a longitudinal axis. The rotor poles each have a first magnet layer having one or more first magnet including a central first magnet having a first transverse axis disposed perpendicular to the central pole axis. The rotor poles each have a second magnet layer radially inset from the first magnet layer and having two or more second magnets that include a pair of inclined second magnets each having a first transverse axis extending at an acute angle to the central pole axis. In relation to the central pole axis, a portion of each inclined second magnet is disposed inboard of an end of the central first magnet.

Abstract: A stator comprising an inner ring, the inner ring comprising a plurality of radially projecting teeth, each tooth being connected to adjacent teeth by respective material bridges at radially inner ends of the teeth, wherein at least some of the material bridges are asymmetric in shape. Each tooth is separated from the adjacent teeth by respective slots, wherein the slots of the inner ring are open at radially outer ends of the teeth. The stator comprises an outer ring, the outer ring located at the radially outer ends of the teeth.

Abstract: An electric drive unit for a hybrid drive, in particular for a vehicle, has an increased power output and degree of efficiency, while thermal loading as well as required installation space and manufacturing costs are minimized. The electric drive unit has an asynchronous machine with a rotor with a rotor cage, in particular a rotor cage which is formed with copper conductors. The asynchronous machine is formed with a stator having a shaft winding. The shaft winding is formed with a device for star-delta changeover. The rotor is formed with a rotor internal cooling device. A step-up gear mechanism is arranged in a power train between the rotor and the output element. There is also described a hybrid drive device with an electric drive unit, and a vehicle that has an electric drive unit and/or a hybrid drive device.
