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.

    一种马达控制装置,控制包括转子及三相的电枢线圈的无刷马达,所述马达控制装置包括:检测转子的旋转位置的位置检测部;在第一或第二控制模式下,以与转子的旋转位置对应的通电时序向逆变器(52)输出第一或第二驱动信号的控制部(54);以及当输入第一或第二驱动信号时,向三相的电枢线圈输出第一或第二通电信号的逆变器(52),关于三相中的任意两个相,在所述第二控制模式中,施加电压的占空相同时的占空的值比所述第一控制模式大。
