ABSTRACT:
A motor control system for driving a stepper motor and a typewriter or the like is provided, the control including reliable means for tracking incremental movements of the stepper and the element being driven by the stepper. Phase combinations of the stepper motor are energized as a function of tracked position, in a manner which optimizes movement from a present position to a target position. Present position is tracked by generating a pair of sensor signals and converting same to digital signals, which digital signals are constrained to change in accordance with the predetermined pattern on a step by step or increment by increment basis. If the pattern is not followed precisely the error is detected and a correction in position information can be made.
