<P>PROBLEM TO BE SOLVED: To reduce torque ripple of a motor producing no-load induced electromotive force having a distortion. <P>SOLUTION: A torque control means 155 can calculate generation torque accurately even for a motor having a distortion in the no-load induced electromotive force by making a function having a distortion act on the output from a current detection means 110, and can improve torque ripple. <P>COPYRIGHT: (C)2007,JPO&INPIT |
