Abstract
A system and method for resolving the angular position of a rotor evaluates the real size of the stripes or gears on the rotor by an auxiliary device, such as a sensor shift device in a first embodiment or a camera in a second embodiment, at a fixed rotor, thus eliminating systematic errors and influence of rotor vibration during this calibration. By knowing the actual size or angular increment or produced sensor signal of each repeating element, a compensation of the error can be made and accuracy can be dramatically increased.
