<P>PROBLEM TO BE SOLVED: To achieve the highly accurate detection of a rotor position by eliminating the influence of the change of zero level without adopting a circuit with especially small dispersion. <P>SOLUTION: To correct the detected value of a motor current, the output from a detection means which detects the above motor current during the pause period of an inverter is detected as zero level. <P>COPYRIGHT: (C)2004,JPO |
