Abstract: The rotation of a rotating magnet is detected by magnetic sensors. The rotational speed is detected from pulse signals detected by magnetic sensors, and the rotational direction thereof is detected from the difference in the way of making a shift in phase. Signals different in pulse width are generated according to the rotational direction. A signal selection circuit outputs a corresponding pulse signal with timing for the rotational speed. A rotational speed determining circuit outputs a decision signal Sf of a high level when the rotational speed reaches a predetermined speed. When a self-diagnostic circuit determines that the magnetic sensors have malfunctioned, a binary error code generating circuit generates an error signal Sg and a 4-bit error code signal Sh.
