Help needed for selecting driver
July 20, 2016 04:30PM

Can I use the easy driver to run a bipolar NEMA 11 captive stepper motor? Its current per phase is shown as 1 amp. Easy driver spec says that the adjustable current control is from 150mA/phase to 700mA/phase. I am not running this motor at fast speed. The motor is supposed to support axial load of about 4 lbs.

Also, does anybody know a place I can get captive stepper motors? I only know Haydon Kerk, but I would like to explore other places with cheaper options.

Thank you!

Unsure what "easy driver" is but a standard Pololu as used in most RepRaps are rated to 2A I believe, certainly able to handle what you need! If in doubt the DRV8825 is the new kid on the block at about 2.5A or so. You can also mix drivers on your MB so should be fine!
