it isn't that simple

i deleted my post , i can rant up a storn on this topic for hours

are optoisolators an option?

if i remember my terminolgoy, you are using a unipolar stepper (it has 3 field windings, and either 5 or 6 wires) bipolar steppers have 3 or 4 wires (two field windings ) the ones with odd numbers share a common on all coils measure the resistance of the wires , once you have found and sorted it int...

PWM is not JUST for servos, they are commonl;y used in all DC brush motors, as well as other motors. correct , the term servo typically applies to a motor with a built in encoder of some sort , basically if you have assembled a motor with soem type of shaft encoder attached, you have built a servo,...

yeah , thats a closed loop feedback system

that is very nice work .... i am truly impressed!!!!!

i looked into those guys too, i made the mistake of sending them my email address , and they won't quit sending me "hurry , this offer won't last" every day !!! and by the way , that modulator looks worse than my second grade science project! :shock: the only l way i could see using that c...

i know exactly where to get what you want .... go to www.smallparts.com and click the product index tab , go to home index , click on drive components. what you want is right in front of you.
