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.

Claim (Index 12):
A servo motor control system for controlling a drive axis servo motor that drives an axis of industrial machinery or a machine tool, comprising:\n a rectifier configured to convert AC power of an AC power supply into DC power and output the DC power to a DC link; a first inverter connected to the DC link and configured to perform power conversion between the DC power in the DC link and AC power serving as drive power or regenerative power of a drive axis servo motor; a flywheel; a flywheel servo motor connected with the flywheel and configured to rotate the flywheel; a second inverter connected to the DC link and configured to perform power conversion between the DC power in the DC link and AC power serving as drive power or regenerative power of the flywheel servo motor; and at least two of the servo motor control apparatuses according to  claim 1 , configured to control each of the drive axis servo motor and the flywheel servo motor, wherein the power conversion by the second inverter is controlled such that the AC power regenerated by the flywheel servo motor is converted into DC power or the DC power in the DC link is converted into AC power for driving the flywheel servo motor in accordance with an output of the drive axis servo motor and an output of the flywheel servo motor, both of which are calculated by the output calculation unit.
