Hi all,
I've been reading about stepper motors and need some help to understand
some of the specs and how to choose the step motor that is best for my
application.
1- What is the difference btw Detent torque and Holding torque ? Which one
is of more importance?
2- I need to get two step motors for my robot (as wheels). The robot is
about 3-4 lbs. I don't need it to go fast, but i want the step motors
to be strong enough to move the robot. I think a reasonable voltage
is btw 9-12v. I don't want to use more than 12 v. I'm not sure about
the Amps i found step motors with 40 mA, 80 mA, 500 mA, ..etc.
How do I know what Amps is best for me? Also what type and value for
torque will i be needing ( 200 g-cm, 400 g-cm, 1000 g-cm, ...)?
3- I've read about Unipolar and Bipolar. What is the major difference btw
them? what things can I do with one that i cannot do with the other?
Which one is easier to use?
thanks in advance
