Hi,

i have stepper motor - 17HS19-1684S, can u suggest me a driver which will work with my stepper motor? ( i want connect this driver to my arduino)

Thank you!


Stepper motor specs:

Frame size 42 x 42mm - NEMA 17
1.8 degree step angle
Length 47mm
Holding torque 44 N.cm (4.4kg.cm, 62oz.in)
Voltage 2.8V
Current/Phase 1.68A
Resistance/Phase 1.65ohm
Inductance/Phase 2.8mH
Inertia 68g.cm
Bipolar, 4-wire
Weight 0.35kg
Step Angle Accuracy ±5%（full step,no load)
Resistance Accuracy ±10%
Inductance Accuracy ±20%
Temperature Rise 80℃Max.(rated current,2 phase on)
Ambient Temperature -10℃-+50℃
Insulation Resistance 100MΩMin. 500VDC
Dielectric Strength 500VAC for one minute
Shaft Radial Play 0.02Max.(450 g-load)
Shaft Axial Play 0.08Max.(450 g-load)

As long as you run it at half current most of the normal drivers will handle it. Whether the torque will be adequate for your application is an unknown.

Thank you for answer. I need only about 2kg holding torque ( of 4,4kg cm ), do you know any specific driver that my be good for these stepper?

Any of the normal stepper drivers should be able to deliver 0.75A to those motors. What control board do you have? If its a Ramps, anything that will plug into the sockets will work. Do you need a stand alone driver board?
