<P>PROBLEM TO BE SOLVED: To provide a control device that corrects a torque error accompanied by the change of the temperature of the permanent magnet type motor without measuring the temperature by a temperature sensor. <P>SOLUTION: The control device of the permanent magnet type rotating motor comprises a position detection means (22) that detects the motor phase of the rotating motor; a torque operation means (10) that obtains each current command value by referring to a torque current conversion map that indicates a relation between and among a torque value that is prepared in advance, the number of revolutions of the motor and a current value on the basis of the number of the revolutions of the motor obtained from the detected motor phase and an imparted torque command value; a conversion means that converts the current command value to each voltage command value; and correction control means (24, 30) each of which obtains the corrected voltage value by referring to a torque voltage conversion map that indicates a relation between and among the torque value acquired simultaneously together with the torque current conversion map, the number of the revolutions and the voltage value; that takes a difference between the voltage value applied to the rotating motor and the corrected voltage value; and that obtains at least one correction value out of currents on the basis of the voltages and the difference. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
