Abstract: In a motor system, a switcher selectively switches a target motor, which is a target to be supplied with electric power output by a motor driver and a target to be detected for a current by a current sensor, among a plurality of motors. The switcher cyclically switches the target motor among the plurality of motors. When the current of the target motor is detected by the current sensor, the motor driver is controlled to output the electric power based on a PWM duty ratio computed based on the current, at a timing when the motor in which the current is detected is again the target motor, in a cycle after the cycle in which the current is detected.

The controller is configured or programmed to control the crane to decelerate in accordance with a detection result of the first sensor and control the crane to stop in accordance with a detection result of the second sensor.

The vehicle controller performs a consistency process based on check information when the transport system is normal and check information when the restart of the transport system is commanded. If there is a vehicle determined to have a problem by the consistency process, the vehicle controller commands the body controller to cancel the check information regarding the vehicle and/or to dispense an article supported by the vehicle for transport to the dispenser.
