Document Type and Number:

WIPO Patent Application WO/2022/185831

Kind Code:

A1

Abstract:

This motor system comprises a motor driver (21), a plurality of motors, a supply switch unit (31), an output control unit, a switching control unit, and a driving force reduction suppression unit. The supply switch unit (31) switches a circuit such that electrical power supplied by the motor driver (21) is supplied to one motor. The output control unit controls the motor driver (21). The switching control unit controls the supply switch unit (31) such that the one motor to which the electrical power is supplied switches periodically. The driving force reduction suppression unit provides control such that while the electrical power is being supplied to one motor among the plurality of motors to which the electrical power is periodically supplied, a reduction in the driving force produced by the other motor or motors is suppressed.
