Pololu NEMA-17 Schrittmotor - Bipolar, 200 Schritte/Rev, 42×38mm, 2.8V, 1.7 A/Phase
This NEMA 17-size hybrid bipolar stepping motor has a 1.8° step angle (200 steps/revolution). Each phase draws 1.7 A at 2.8 V, allowing for a holding torque of 3.7 kg-cm (51 oz-in).
This hybrid bipolar stepping motor has a 1.8° step angle (200 steps/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; red and blue connect to the other. It can be controlled by a pair of suitable H-bridges (one for each coil), but we recommend using a bipolar stepper motor driver. Our DRV8825 stepper motor driver carrier is probably the best option for this stepper motor.
Our 5 mm universal mounting hub can be used to mount objects on the stepper motor’s 5 mm-diameter output shaft, and our NEMA 17 aluminum bracket offers a variety of options for mounting this stepper motor in your project. This NEMA17 stepper motor is also available with threaded rod output shafts in lengths of 18 cm, 28 cm, or 38 cm that convert its rotations into linear motion of the included traveling nut.
