摘要： A sensor device for contactless determination of a radial position of a rotor has a target unit on the rotor with an electrically conductive target material. A coil unit is adapted for electromagnetic interaction with the target material. A control unit is electrically coupled to the coil unit and is designed to excite a coil of the coil unit with an excitation signal and to detect and evaluate a response signal of the coil unit in to determine the radial position of the rotor. The target unit has target elements with the target material in the direction of rotation on the rotor separated by a gap and the gaps of the target unit. Coil(s) of the coil unit are matched to each other in their geometry in such a way that the temporal change of the portion of the coil projected onto the target unit in a radial projection.

摘要： Disclosed is a dual motor unit for a flywheel mass accumulator, with at least two electric machines coupled to a common rotary body; wherein the electric machines have different power characteristics and the dual motor unit is adapted to provide a total operating power in an operating speed range (Ω) by an interaction of the electric machines. The power characteristic (Pmax) is non-linearly dependent on a rotational speed (ω) of the common rotary body.
