<p>A rotational speed control system, comprising a plurality of motor drivers for driving a plurality of motors at a same rotational speed without relying upon the quantity of the motor drivers and the characteristics of the motor drivers, wherein a remote controller (31) and the motor driver (202) are connected to the motor driver (201), the motor drivers (201, 202) control the motors (M11, M12) at specified rotational speeds, and a rotational speed instructing signal (91) indicating the rotational speeds is given from the remote controller (31) to the motor driver (201) and then given from the motor driver (201) to the motor driver (202), whereby since the rotational speed instructing signal (91) instructs the rotational speeds digitally exchanged between the motor drivers (201, 202), both motors (M11, M12) can be driven at the rotational speeds instructed by the rotational speed instructing signal (91).</p> |
