<p>The arrangement has a filter (102) i.e. high-pass filter, connected with a star point of a motor (101) and an oscillator. The filter is provided with an inductor-capacitor element and a resistor-capacitor element, where a high frequency (HF) signal and a HF voltage signal in zero components passes through the filter. An evaluation unit determines current components of the HF voltage signal, where the current components are converted into a rotor angle (109) by trigonometric functions. The star point is connected with a signal generator (103) by the filter. An independent claim is also included for a method for determining a rotor position.</p> |
