The purpose of the present invention is to reduce operation stoppage due to an abrupt decrease in rotational speed. The motor device includes: a motor that is rotationally driven; a drive signal generation unit that controls a duty ratio indicating a drive output of the motor so that the duty ratio does not exceed a duty ratio upper limit value, and generates a drive signal corresponding to the duty ratio; an inverter that outputs an output signal for rotationally driving the motor on the basis of the drive signal; a rotational speed detection unit that detects the rotational speed of the motor; an acceleration detection unit that detects whether or not the motor is in acceleration; and an upper limit value setting unit that, when the rotation of the motor is accelerated, changes the duty ratio upper limit value to a second upper limit value that is higher than a preset first upper limit value.
本发明降低因突发性的转速下降造成的动作停止。马达装置包括:马达,进行旋转驱动;驱动信号生成部,对表示所述马达的驱动输出的占空比进行控制以使其不会超过占空比上限值,并生成与所述占空比相应的驱动信号;逆变器,基于所述驱动信号来输出使所述马达旋转驱动的输出信号;转速检测部,检测所述马达的转速;加速检测部,检测所述马达是否处于加速中;以及上限值设定部,在所述马达的旋转处于加速中的情况下,将所述占空比上限值变更为比预先设定的第一上限值高的第二上限值。
