A method for controlling a motor can suppress an influence of speed variation due to cogging of the motor. The method includes performing a preliminary drive process to output a first driving signal to the motor to move the mechanism, performing the preliminary drive process to output a second driving signal corresponding to a cogging period of the motor to the motor as well as output the first driving signal, to move the mechanism, determining parameters which include an output waveform and output timing of the second driving signal based on a speed of the mechanism in the preliminary drive process, and outputting the second driving signal according to the determined parameters to the motor as well as outputting the first driving signal to the motor in an actual drive process to perform predetermined processing by moving the mechanism.
