Abstract
A servomotor control system of the present invention includes: a multiple number of first servomotors for driving axes in a machine tool or others; a multiple number of converters for converting AC voltage into DC voltage; a multiple number of first inverters for converting DC voltage into AC voltage; second servomotors for rotating inertial bodies; a multiple number of second inverters for converting DC voltage into AC voltage; and a servomotor control unit for controlling the multiple first servomotors and the second servomotors, and is constructed such that the number of the second servomotors is less than that of the multiple second inverters, and at least one of the second servomotors includes a multiple number of independent windings, and at least part of the multiple second inverters are connected to the multiple independent windings provided for one of the second servomotors.
