i worked on the stepper today..well i accelarated the motor as u said and the results i got are:
the max. rpm it is giving is 20 no matter how quickly or slowly i accelarate it.(i tried to accelarate it from 1rpm to 30 rpm but it gives max. of 20 rpm..)
this rpm is independent of the input com. voltage.(i trid from 6v to 20v and only the torque changes on changing the voltage)..
so, should i assume that the max. rpm of the stepper is 20 or it can be increased in any other way??
how do we generally check the max. rpm of a stepper?
is placing resistors a solution??
@duffy..looking forward 4 a reply..thanks in advance..
@others..please read the prev. posts for specifications of my motor and driver.
