Abstract:
1. An assembly for determining a current angular position of an object rotating around a stationary point, the assembly comprising: an inductive sensor having at least one primary winding being fed an excitation signal and at least two secondary windings inductively coupled thereto, said inductive coupling causing signals to be generated with a periodic and phase-shifted waveform in said two secondary windings depending on a rotation angle, said at least two secondary windings including a first secondary winding and a second secondary winding; three phase shifters each with one input and one output, said phase shifters having same phase shifts, each being electrically coupled on said input with said primary winding, said first secondary winding or said second secondary winding respectively; and an evaluation unit for determining the current angular position from the signals at said inputs and at said outputs of said phase shifters.
