PROBLEM TO BE SOLVED: To synchronously control the rotating operations of a plurality of brushless DC motors by a single control device.SOLUTION: A brushless DC motor control device comprises: a signal input section 13 for inputting a superposition signal of each phase, in which a plurality of rotated position signals are superposed for each phase, the plurality of rotated position signals being output from the corresponding holes IC of a plurality of brushless DC motors, which detect the rotated position of a rotor corresponding to a stator, output a rotated position signal indicating the rotated position, and which are arranged so as to correspond to a plurality of phases with predetermined spaces left in a rotating direction; a detecting section 17 that detects the rotated position signal of a specific brushless DC motor of the plurality of brushless DC motors based on the superposition signal of a specific phase of the superposition signal of each phase; and a drive control section 12 that generates a driving signal for driving the specific brushless DC motor based on the detected rotated position signal of the detected specific brushless DC motor. A generated driving signal is output as a driving signal for each of the brushless DC motors. |
