Electrical machine for a motor vehicle, device for determining the torque absorbed or released by the electrical machine

摘要

The invention relates to a device (100) for detecting an electrical machine (80) for a motor vehicle (10) that can be operated on a first shaft (15) of an electrical machine (80), in particular on a stator shaft (15) of a motor or generator. , Torque M acting along an axis of rotation, the device having a further shaft for torque transmission arranged in the direction of a torque flow of the electrical machine (80), the first shaft (15) and the further shaft being mechanically coupled to one another in order to drive the first Shaft or the further shaft to cause a transmission of torque (M) and axial force between the shafts (15, 20), the device further comprising a sensor unit (30) which is set up to transmit one between the shafts (15, 20) acting axial force or a representative quantity as a measure of a torque (M.) acting on at least one of the shafts (15, 20) ) capture. The invention further relates to an electrical machine with a device for determining a torque acting on an electrical machine (80) and to a method for determining such a torque.
