Abstract
A motor driver supplies electric power to a plurality of motors. A switcher selectively switches a target motor to which the electric power output from the motor driver is supplied among the plurality of motors. An output controller includes a plurality of motor controllers, each of which performs control on any one of the plurality of motor, and controls the motor driver so that the motor driver outputs the electric power based on an output from each of the plurality of motor controllers. A switching controller controls the switcher so that the target motor is cyclically switched among an equal or fewer number of motors out of the plurality of motors compared to a number of the plurality of motor controllers.
Claims7
A motor system, comprising:
- a plurality of motors;
- a motor driver that supplies electric power to make the plurality of motors generate driving force;
- a switcher that selectively switches a target motor to which the electric power output from the motor driver is supplied among the plurality of motors;
- an output controller that includes a plurality of motor controllers, each of which performs control on any one of the plurality of motors, and controls the motor driver so that the motor driver outputs the electric power based on an output from each of the plurality of motor controllers;
- and
- a switching controller that controls the switcher so that the target motor is cyclically switched among an equal or fewer number of motors out of the plurality of motors compared to a number of the plurality of motor controllers.
