<P>PROBLEM TO BE SOLVED: To provide a motor controller which improves the control accuracy of a motor. <P>SOLUTION: The motor controller 10 for controlling a plurality of motors is equipped with an IPM 14, a microcomputer 20 for control, a current sensor 15, etc. separately for each motor 10. A microcomputer 20 for control generates a drive signal S, based on a current detected value I detected with a current sensor 15 and converted with an A/D converter 16. An IPM14 opens and closes a switching element, based on the drive signal S inputted from the microcomputer 20 for control, and generates a drive current. A supply part 22 detects the opening and closing timing of the switching element from the drive signal S. The microcomputer 20 for control shifts the timing of current detection in case that the opening and closing timing and the detection timing of a current accord with each other. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
