<P>PROBLEM TO BE SOLVED: To prevent feedback to an oscillation circuit in a resolver detection unit to reduce a number of parts based on the output of the resolver detection unit, and to carry out motor drive control based on an ideal output signal. <P>SOLUTION: Feedback to the resolver detection unit 58 is not carried out at all, and so-called digital processing is carried out. That is, with respect to rotational angle, differences (correction data) are prepared beforehand, and correction is carried out step by step. This processing makes it possible to enhance the accuracy of signals from the resolver detection unit 58, and to simplify the configuration of the equipment. <P>COPYRIGHT: (C)2008,JPO&INPIT |
