Apparatus and method for detecting rotation

Abstract

In a rotation detection apparatus, a rotation-angle detector (14) detects a rotation angle of a rotating body based on an output signal generated by a resolver. An exciting-signal generation circuit (53) supplies an exciting signal for exiting the resolver to generate the output signal. An abnormality detection circuit (3) detects an abnormality of an exciting-signal output terminal for outputting the exciting signal or an abnormality of an exciting-signal line for transmitting the exciting signal. A power-supply stopping circuit (3) stops a power supply to the exciting-signal generation circuit when the abnormality detection circuit detects an abnormality of the exciting-signal output terminal or detects an abnormality of the exciting-signal line.
