Make a simple ramp generator for stepper-motors -  4-Apr-02 Issue of EDN  Stepper motors are synchronous motors that step at the pulse rate of the driving signal. For the motor to move quickly, the stepping rate must be fast. However, because of motor and load inertia, the motor often cannot go from 0 rpm to the desired number of revolutions per minute in one step. Therefore, most stepper motors receive their drive from a pulse chain that starts out slowly and.... [Design Idea by Richard Brien, GSI Lumonics, Wilmington, MA]
