<P>PROBLEM TO BE SOLVED: To provide a motor control device that detects a current more accurately when a current detection circuit and an exciting circuit of a motor resolver share one grounding wire. <P>SOLUTION: The motor control device is configured such that the current detection circuit and the exciting circuit share one grounding wire. A microcomputer that serves as a current detecting means sets a phase of an exciting current such that values of an excitation noise superposed on an output voltage of the current detection circuit at respective timings (L1, H1, L2, H2, ...) when the output voltage thereof is acquired in one current detection process, are equalized. <P>COPYRIGHT: (C)2011,JPO&INPIT |
