Motor system

A motor system comprising:

• a plurality of motors;
• a motor driver that generates and outputs a drive waveform to make the plurality of motors generate a driving force by PWM control;
• and
• a switcher that selectively switches a target motor, to which electric power output by the motor driver is supplied, among the plurality of motors, wherein
• the switcher is controlled by a switching controller so that the target motor is cyclically switched among the plurality of the motors,
• the electric power output by the motor driver is supplied only to the target motor among the plurality of motors connected to the switcher,
• a carrier cycle of the PWM control includes a high-level period during which PWM output is high level and a low-level period during which the PWM output is low level, and
• the switching controller controls the switcher so that the switcher switches the target motor during the low-level period.
