摘要
An angle detecting device with self-calibration function, in which sensor heads are provided with an equiangular interval on a scale disc fixed to a rotating shaft, one sensor head is selected as reference, a sum of measurement differences between the reference and another sensor head is divided by the number of sensor heads, to determine an average, whereby a self-calibration value is obtained, in which a sensor head of the reference is changed to another in order, and the respective self-calibration value is obtained, which value is deviated by an angle of arrangement with respect to a particular sensor head, and a phase is aligned to a self-calibration value of the particular one as the reference, to determine an average for calculations of this phase conversion, which average is subtracted from the respective calculation subjected to the phase conversion, to obtain only asynchronous angular errors.
