<P>PROBLEM TO BE SOLVED: To solve the problem that a motor controller requires a simplified system for calculating the correction gain factor and a shorter time for adjusting the correction gain factor. <P>SOLUTION: The motor controller drives a motor with three-phase alternating current output from an inverter, and includes a current detector and a detected current correcting unit to carry out current feedback control. The detected current correcting unit samples the detected current signals Iu and Iw, at each phase when the motor operates at a rating speed, to determine a sampling value at each phase, and calculate the correction gain factor KP from the sampling value at each phase. <P>COPYRIGHT: (C)2010,JPO&INPIT |
