Abstract: A brushless electric machine, in particular a brushless DC motor, has a stator and a rotor arranged within the stator so as to be rotatable relative thereto. The rotor has a cylindrical base body which is non-rotatably connected to a machine shaft and carries a plurality of permanent magnets on its outer circumference, and the stator has a stator winding with a plurality of single-tooth windings for driving the rotor via an electrically generated rotating magnetic field. The permanent magnets of the rotor are fixed by a thin-walled reinforcement radially surrounding them, wherein the reinforcement has a modulus of elasticity of at least 150 GPa and/or a yield strength of at least 600 MPa.

Abstract: A motor vehicle steering system may include an electric motor and a control unit that controls the electric motor. The control unit may have at least two redundant control paths for controlling the electric motor and an asymmetry detection device. The asymmetry detection device may be configured to compare electric current intensities of the at least two redundant control paths and to cause a faulty control path to be interrupted when there is asymmetry. Each of the at least two redundant control paths may include a switching element that is connected to the asymmetry detection device for interrupting the respective redundant control path.

Abstract: Stator (10), electric machine (9), and method for manufacturing an electric machine (9), with a stator base body (34), which comprises radial stator teeth (14) for receiving an electric winding (20), wherein the electric winding (20) is connected to a separately manufactured connection plate (52), which comprises contacting modules (60) for the energizing of individual phases (U, V, W) of the electric winding (20), wherein electric conductor elements (54) are arranged in a radial plane of the stator (10) on the connection plate (52), which, on the one hand, are connected to winding wires (22) of the electric winding (20) and, on the other hand, carry the contacting modules (60), wherein the conductor elements (54) comprise a plurality of angled portions (56) within the radial plane, which make a spring-loaded compensation movement of the contacting modules (60) in the radial plane possible.
