Disclosed herein are a motor control apparatus, an image forming apparatus, an image forming apparatus including the same, and a motor control method, by which position error of a motor and a control value for compensating for the position error are calculated and reflected in feedback control, thereby quickly removing position error of the motor. The motor control apparatus includes a detector to detect rotation of a motor to output a feedback signal, a measurer to measure speed and phase difference of the feedback signal and a target signal applied to the motor and to measure position counts by counting rising edges or falling edges of the target signal and feedback signal using a reference clock signal, and a calculator to calculate speed error of the motor from the measured speed of the target signal and feedback signal, to calculate position error of the motor from the measured position counts of the target signal and feedback signal, and to calculate control values for compensating for the speed error, the position error, and the phase difference. |
