Abstract: A rotor for an electric machine, with rotor shaft, with plurality of rotor poles distributed in circumferential direction with magnet unit, with lamination stack which has a lamination core and insert segment for each rotor pole. The lamination core has a central shaft receptacle for receiving the rotor shaft and, for each rotor pole, a radially outwardly open segment receptacle for receiving the magnet units and the insert segments, and with a wrap surrounding the lamination stack which the magnet units and the insert segments are in the respective segment receptacle. The shaft receptacle has a plurality of supporting surfaces distributed in circumferential direction, and the rotor shaft has a plurality of mating surfaces (22) distributed in circumferential direction, and a supporting surface is supported in each instance at a mating surface of rotor shaft in radial direction with reference to rotational axis of rotor.

Abstract: An electric machine for a vehicle that has a housing, a rotor assembly which can rotate about a rotational axis in the housing, a contactless power transmission device for transmitting electricity to the rotor assembly, in which the power transmission device contains a housing transmitter and a rotor transmitter, wherein the housing transmitter contains a primary core and primary coil, and the rotor transmitter contains a secondary core and a secondary coil, wherein there is a fluid tube for supplying the rotor assembly with fluid that runs coaxially through the rotor assembly, in which the fluid tube has at least one fluid outlet inside the power transmission device, such that a fluid flow path runs through the power transmission device in order to cool the power transmission device.

Abstract: An oil guiding component for an oil guiding arrangement has a body rotationally fixedly connectable to a stationary component of the oil guiding arrangement, the stationary component defining a main oil channel. The body defines a first chamber opening in a radial direction toward an outer side of the body and being fluidly connectable to the main oil channel. The body also defines a second chamber opening in the radial direction toward an inner side of the body. The first chamber is outside of the second chamber in the radial direction and overlaps the second chamber in an axial direction. The first chamber is fluidly connected to the second chamber via a connection passage. The second chamber is fluidly connectable to a shaft passage through which an outer side and an inner space of a second output shaft of the oil guiding arrangement are in fluid communication.

Abstract: An electric motor is described, having a rotor, a stator, a housing surrounding the elements having a circumferential wall and an end wall, and an air-guiding element arranged axially between the end wall and an end surface of the rotor. The air-guiding element has a first section that is disk-shaped about the axis (A) and axially spaced apart from the end wall and which extends radially and a second section of tubular form about the axis (A) and which adjoins the first section radially at the inside and which extends in the direction of an end surface of the rotor. The air-guiding element forms an air channel with a heat-exchange region situated between the first section and the end wall and with an intake region running within the second section.
