Title:
SERVO POWER SUPPLY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/195552
Kind Code:
A1
Abstract:
In this servo power supply system for supplying power to multiple motor control devices, each of multiple motor control devices performs PWM control of a motor at a PWM period of period T, each of the multiple motor control devices belongs either to a first group or to a second group, and a time difference of 1/2 the period T is provided between the start timing of the PWM period of the motor control devices that belong to the first group and the start timing of the PWM period of the motor control devices that belong to the second group. This configuration enables decreasing noise current in the power supply system.
