<p>PROBLEM TO BE SOLVED: To provide a position detector that can acquire position information which is finally needed in a short time without interpolation processing with a large load by use of a position sensor capable of generating a multiphase periodic signal.SOLUTION: A position detector uses a position sensor capable of generating periodic signals of a sine wave which is at least four phases each having a constant phase difference, selects required periodic signal regions from the plurality of periodic signals and connects them to each other, and thereby outputs position information of the periodic signal as amplitude information (voltage information).</p> |
