A servo motor includes a motor, a motor driver for driving the motor by outputting pulses to the motor, and a speed detector for calculating speed information. The servo motor further includes a comparator for comparing the speed information with command speed information and calculating deviation information therebetween, a memory for storing pulse correction information for modifying a duty factor of the pulses in accordance with a rotational state of the motor, and a pulse updater for reading the pulse correction information stored in the memory based on the deviation information, modifying the duty factor of the pulses, and outputting the duty factor modified pulses to the motor driver.
