This hybrid Stepper Motor Nema 17 Bipolar, 1.7A, has a 1.8° step angle (200 steps per revolution). Each phase draws 1.7 A at 2.8 V, allowing for a holding torque of 3.7 kg/cm (51 oz/in).

The motor has four color-coded wires terminated with bare leads: black and green connect to one coil, and red and blue connect to the other. Size: 42.3 mm square  38 mm, not including the shaft (NEMA 17).

• Weight: 285 g (10 oz)
