Are you using the "smooth" PWM motor routines? Note also, that a DC motor
does not change velocity linearly with an increase in current unless it is
under load. This was a recently asked question on the list. Maybe
grepping the digest for "motor" "DC" and "PWM"?

| Hi, i have some questions about PWM and encoder. I made following tests: 1) Speed : motor(0,100) my encoder count f.e. 20clicks / per second 2) Speed: motor(0,50) my encoder count f.e. 15clicks / per second 3) Speed: motor(0,40) my encoder count (...)
