Abstract: An electric machine for use within a vehicle powertrain, including a stator and a rotor which is separated from the stator by an air gap. The rotor has a first rotor body with a first permanent magnet group and a second rotor body with a second permanent magnet group. The first and second rotor bodies are rotatable relative to each other about a common rotational axis against the effect of first rotational stiffness by a mechanical field-attenuating mechanism. At least one first spring leg of the first leg spring is held in a first receiving shoe, which is received in a first receiving pocket of the first rotor body and fixed to the first rotor body such that the first spring leg of the first leg spring is coupled to the first rotor body in a play-free manner in the axial and circumferential directions relative to the first rotor body.

Abstract: An electric axial flux machine having a stator with first and second stator elements arranged spaced apart axially from one another, and a rotor with a rotor body arranged on a rotor shaft, in the form of a disk and arranged axially between the first and second stator elements, the first and second stator elements being arranged movably in the axial direction in relation to the rotor body. An adjustment device is provided to adjust the first stator element and the second stator element in the axial direction in order to set an air gap. The adjustment device adjusts the first stator element and the second stator element in the axial direction depending on a torque which is to be transmitted via the rotor shaft and which generates a resulting supporting moment on the first stator element and on the second stator element.

Abstract: A module, in particular a rotor assembly (2) or stator assembly (49), for an electrical machine (1, 45), including multiple components (3), wherein at least one volume filled with a damping fluid is formed between at least two of the components (3), wherein, for the purpose of vibration damping, the damping fluid is displaceable as a result of a change in the geometry of the volume resulting from an elastic vibration of at least one component (3) adjacent to the volume.
