Abstract
A method of calculating a compensation value for an angle detecting sensor including a sensor unit, a signal converting section, a signal adjusting section, an arithmetic operation section, a memory section, and a compensator includes a first step of generating two signals having a predetermined phase difference from a plurality of output signals; a second step of calculating a rotation angle of an object from the two signals as an output angle before compensation; and a third step of extracting a candidate signal having a minimum residual energy in the signal after removal as the compensation value when a plurality of candidate signals having the same period but different amplitudes has been removed from a total error signal included in the output angle before compensation.
