Abstract
A brushless resolver having a stator and a rotor, and a resolver part axially displaced to one another and a transformer part and having associated windings is provided. An additional short-circuited winding arranged parallel with the transformer rotor winding with few turns on the iron core thereof is also provided. A lowpass filter is thereby formed, which compensates the unwanted frequency-dependent phase displacement between the input voltage and the output voltages for the respective frequency.
