ABSTRACT:
A control system of a step motor and a method thereof are capable of evenly maintaining a traveling distance and a torque in a moving section, especially in an accelerating section, by limiting a start excitation phase or a final stop phase to a specific phase, even though an excitation and the torque are unevenly generated due to an imbalance in a step angle generated during the manufacturing and/or assembly of the step motor.
