Abstract
A motor device includes motors, detector in the respective motors to detect motor rotational speeds, and an output controller configured or programmed to output a single output rotational speed based on the motor rotational speeds input from the detectors. The output controller multiplies at least one of the input motor rotational speeds by a coefficient derived based on target rotational speeds of the motors to calculate a conversion value, and determines the output rotational speed.
