PROBLEM TO BE SOLVED: To provide a motor drive control device that can suppress variations in the rotation of a motor.SOLUTION: The motor drive control device has a control circuit section 4 for outputting a drive control signal Sd, and a motor drive section 2 for driving a motor 20 on the basis of the drive control signal Sd. In the control circuit section 4, a speed control circuit 31 outputs speed command information S1 on the rotational frequency of the motor 20, and a current feedback gain adjustment circuit 33 outputs subtraction information S2 corresponding to a detection result of a current detection circuit. A subtraction circuit 34 subtracts the subtraction information S2 from the speed command information S1 to output post-subtraction command information S10, and a sine wave drive circuit 35 generates the drive control signal Sd on the basis of the post-subtraction command information S10. |
