Abstract
The present invention relates einen energy-self-sufficient multiturn rotary encoder for detecting a number of complete 360° revolutions of an encoder shaft, rotating about a rotational axis and to which an excitation magnet is mounted in a rotationally fixed manner for generating an external magnetic field, as well as for determining an absolute rotational angle indicating a fine-resolved position within one 360° revolution of the encoder shaft, wherein the multiturn rotary encoder for energy-self sufficiently detecting the number of the complete 360° revolutions of the encoder shaft several functional blocks comprises. Further, a corresponding method is taught.
