Title:
MOTOR SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/127252
Kind Code:
A1
Abstract:
In a motor system (1), a switch unit (22) selectively switches a target motor among a plurality of motors (23), the target motor to which electric power output by a motor driver (21) is supplied, and from which current is detected by a current sensor (35). The switch unit (22) cyclically switches the target motor among the plurality of motors (23). When the current of the target motor is detected by the current sensor (35), the motor driver (21) is controlled to output power based on the PWM duty ratio obtained on the basis of the current, in the cycle after the cycle in which the current is detected, at the timing when the motor (23) of which current is detected becomes the target motor again.
