Application of a Computer Control to a Study of Open-Loop Acceleration of Step Motors

A study on open-loop computer control of step motors is presented. The investigation centers around the problem of determining the best open-loop acceleration schemes for step motors. It is found that if a computer first calculates the pulsing scheme and then generates it: and drives the motor, great flexibility is obtained. A large number of pulsing schemes can be generated and used with a minimal expenditure in time and effort. Results are presented for a typical step motor using 10 different acceleration schemes.
