The 17HS4417L20P1-X2 is a two-phase Nema 17 step motor that has a step angle of 1.8° (200 steps/rev). It comes with a connector for easy installation. Each phase draws 1.7 A at 2.55 V, which enables a holding torque of 40 Ncm. The motor has four color-coded wires: black and green represent one coil; red and blue represent the other. 17HS4417L20P1-X2 stepper motor can control a pair of matching of H-bridges (one for each coil) but we recommend using it stepper motor driver.

How to connect Nema 17 stepper motor 40Ncm +connector with a driver?

As shown in the diagram below, there are four different colored wires viz. red, green, black and blue. The wires are connected to two different coils. Black and green are connected to one coil and red and blue to another. The logical sequence of power supply to the coils allows the motor to rotate.
