Publication number: 20210199174Abstract: A torque transfer device is provided, for a powertrain of a motor vehicle, comprising an electric motor having a stator and a rotor rotatable relative thereto. A control system is provided which can output a current pulse to the electric motor, wherein the current pulse effects a rotary motion of the rotor in a first direction of rotation and through a first angle of rotation and thus effects an induced voltage, which is received by the control system to determine the direction of rotation or the rotary position of the rotor in relation to the stator. The rotor is connected to a torsional vibration damper comprising a damper input and a damper output; rotatable in a limited manner in relation to the damper input, against the effect of energy storage elements, and the rotary motion of the rotor causes a relative rotation between the damper input and the damper output.Type: ApplicationFiled: June 3, 2019Publication date: July 1, 2021Applicant: Schaeffler Technologies AG & Co.
