Abstract
A motor control device includes: a first duty ratio computation unit to compute a first duty ratio to be used for control of a motor body portion on the basis of a target rotational position of a rotor and a rotational position of the rotor; a second duty ratio computation unit to compute a second duty ratio corresponding to an upper limit of the absolute value of the first duty ratio on the basis of a linear function including a variable corresponding to the number of rotations of the rotor; and a control signal output unit to output a control signal corresponding to the first duty ratio when the absolute value of the first duty ratio is smaller than the absolute value of the second duty ratio, and to output a control signal corresponding to the second duty ratio when it is not.
