An electric radial flow machine having a stator, a rotor body connected to a rotor shaft, and a spring element which applies a spring force to the rotor body in the axial direction such that in a first operating position, the rotor body is held in an axial position in which the overlap between opposing surfaces of the rotor body and the stator is less than 100%. A displacement device with first and second displacement elements generates an axial movement between the rotor body and the stator against the spring force using a torque produced between the rotor shaft and the rotor body so that in the event of a rotation of the first displacement element relative to the second displacement element or vice versa, the rotor body is pushed on the rotor shaft axially against the spring force.

Electrical radial flow machine and powertrain

An electric machine designed as a permanently excited synchronous machine, including a rotor with a rotor body arranged on a rotor shaft, a stator, and a displacement device that generates a relative axial movement between the rotor body and the stator based on a torque produced between the rotor shaft and the rotor body. The displacement device has first and second displacement elements and at least one rolling body arranged between the first and second displacement elements. The first displacement element is axially movable and rotatable to a limited degree on the rotor shaft, and the second displacement element is connected to the rotor shaft rotationally fixed. The displacement elements provide that upon rotation of the first displacement element relative to the second or vice versa, the rotor body is pushed on the rotor shaft axially against the spring force.

Electric machine, displacement device for an electric machine, and powertrain for a motor vehicle

An electric machine includes a stator, a rotor, a housing and a shaft. The stator is connected to the housing via an electrically insulating torque support. An electrically insulating flange is disposed on the shaft. The shaft is connected to a flange of a bearing shaft via said flange, the bearing shaft housed in a bearing which is arranged in the housing.
