Abstract
An assembly and a method determine the angular position of a rotating machine by way of an inductive sensor. From the excitation signal for a primary winding of a sensor and voltages induced in the two secondary windings of the sensor, three more signals are derived using phase shifters and polarity sign determination units. The six signals in total are sampled using a sample and hold sampling unit and provided to a processor for evaluation, which then calculates the current angular position of the rotating machine at the sampling time.
