NEMA17 Stepper Motor with 28cm Lead Screw: Bipolar, 200 Steps/Rev, 42×38mm, 2.8V, 1.7 A/Phase

Description

This NEMA 17-size hybrid bipolar stepping motor has an integrated 28 cm (11″) 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).

This linear positioning drive consists of our 42×38 mm NEMA17 stepper motor with a built-in lead screw in place of the normal output shaft, which makes it easy to move an object or platform in a linear motion with the precision of a stepper motor. Motors like this are especially popular for use in home-built 3D printers and CNC machines. The stainless steel threaded rod extends from the face of the stepper motor, and since it is integrated into the motor itself, you do not have to deal with bulky shaft couplers or loose set screws.
