Abstract
A servo direct-current feeder system can reduce an oscillating voltage across a power feeding path. The servo direct-current feeder system includes a direct-current power supply, a plurality of motor controllers that each control a servomotor, and a power feeding path that distributes power from the direct-current power supply to the plurality of motor controllers. Each of the plurality of motor controllers includes a current control loop unit that controls a current flowing through the servomotor. The current loop unit includes a current control loop including a notch filter having a center frequency corresponding to a frequency to occur from an oscillating voltage across the power feeding path.
