Abstract
A speed control for step motors is provided with a speed control circuit for periodically actuating a motor driving circuit at least in part in response to timing signals representative of the incremental advance of the step motor during acceleration. The time interval between the respective actuations of the motor driving circuit during acceleration is stored in a memory, the speed control circuit actuating the motor driving circuit during deceleration of the step motor at intervals which are a function of the stored acceleration intervals in the memory, applied in reverse order.
