Make a simple ramp generator for stepper motors:
04/04/2002 EDN - Design Ideas / 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 ... . |
