<P>PROBLEM TO BE SOLVED: To provide a servomotor control device which can perform stable operation in all the regions with magnetic saturation appearing so as to sufficiently attain miniaturization. <P>SOLUTION: A control gain reduction part 13 receiving a detected speed ωof a motor 1 is provided, a proportional gain Kp of a current control integration arithmetic part in a current control unit 9 is made to be reduced in accordance with decrease in a rotational speed of the motor 1. Including the situation even when it is servo locked, the motor 1 is controlled so as to suppress generation of control instability due to magnetic saturation of the motor 1 in a low speed condition. <P>COPYRIGHT: (C)2003,JPO |
