This NEMA 17-size hybrid bipolar stepping motor has an integrated 38 cm (15″) threaded rod as its output shaft, turning it into a linear actuator capable of precision open-loop positioning. The included traveling nut has four mounting holes and moves 40 µm (1.6 mil) per full step; finer resolution can be achieved with microstepping. The stepper motor has a 1.8° step angle (200 steps/revolution) and each phase draws 1.7 A at 2.8 V, allowing for a holding torque of 3.7 kg-cm (51 oz-in).
