A motor control device for controlling a brushless motor comprising a rotor and a three-phase armature coil, said motor control device comprising: a position detection unit which detects the rotational position of the rotor; a control unit (54), which, in a first or second control mode, outputs a first or second drive signal to an inverter (52) at a current-supply time based on the rotational position of the rotor; and the inverter (52) which outputs a first or second current-supply signal to the three-phase armature coil when the first or second drive signal is input, wherein for any two of the three phases, a duty value when the duty of the applied voltages is the same is larger in the second control mode than in the first control mode.
