Abstract
Certain embodiments provide an angle detector comprising: an AD converter configured to analog-to-digital convert plural-phase signal waves having respective different phases; a corrector configured to delay a phase of an excitation signal by an amount corresponding to a phase difference between the excitation signal and the signal wave; a wave detector configured to perform synchronous detection to an output signal from the AD converter in synchronization with the excitation signal whose phase is corrected; and an angle calculator configured to calculate an estimated rotation angle using an output signal of the wave detector and output the estimated rotation angle to the AD converter.
