Abstract
A driving system for a pulse motor, particularly of a sewing machine, includes an electronic memory for determining the time series of drive pulses to control the speed of the pulse motor according to a number of moving steps. The system is provided with a number of calculating devices operated in accordance with calculating formulas reflecting the functions of the number of stepping pulses to control the stepping speed of the pulse motor in accordance with the number of steps needed by the pulse motor to move a given distance.
