Nema 17 stepper motor wiring diagram. This shows that the stepper motor in general starts at a low rpm and the torque decreases as the speed increases. Assuming you don t already have it read the model number off of the motor and then search for it on the internet. Each phase draws 1 2 a at 4 v allowing for a holding torque of 3 2 kg cm.

The trick is figuring out which wires make up the coil pairs. I highly recommend to also take a look at the example codes for the accelstepper library at the end of this tutorial. My nema 17 requires 12v to work.

If your stepper motor has 4 wires it is a bipolar stepper motor. The nema 17 stepper motors are found in several dozen models so be careful with the motor model used in your project. Bipolar stepper motors have two windings which are not connected to each other wired internally like this.

I have included a wiring diagram and many example codes. I connected the 12v output from the power adapter to the a4988 driver to power the nema 17 motor. This library is fairly easy to use and can greatly.

Here s three ways to figure this out. In the first example we will look at the stepper h arduino library. Nema 17 stepper motor cable reprap motor wiring dupont 4pin 6pin cable 42 motor wire xh2 54 connector nema17 wire 5pcs lotofficial store check here.

This is a datasheet of a nema 17 6 wire which can be connected as bipolar or as unipolar. Nema 17 stepper motor is generally used in printers cnc machines and laser cutters. Since coils a and b on the diagram above are not connected the resistance between leads a1 and b1 or between a1 and b2 will be infinite.
