Abstract
A servo motor control apparatus for controlling a servo motor includes a storage unit configured to store a torque constant predefined for the servo motor, a torque constant correction unit configured to correct the torque constant stored in the storage unit when magnetic saturation occurs in a winding of the servo motor, and an output calculation unit configured to calculate an output of the servo motor on the basis of the torque constant stored in the storage unit or the torque constant after correction calculated by the torque constant correction unit, a value associated with a current of the servo motor, and a value associated with a speed of the servo motor.
