I am trying to figure out the best stepper driver to use for my stepper motor. The motor parameters can be found here
I am going to be using it in the Bipolar configuration
I = 2.1
V = 2
R = .96
I tried the L6470 which did not work with this motor. The torque was bad even at low speeds and the chip got really hot. I am new at trying to match a driver to a motor so any help would be appreciated.
