Optical Feedback 1000PPR Encoder Integrated Stepper, 0.06Nm – Nema 11 Closed_loop Compact Design

Product Overview

This Nema 11 closed-loop stepper motor integrates a high-resolution 1000PPR (4000CPR) optical incremental encoder, delivering precise motion control and real-time feedback. With a holding torque of 0.06Nm (8.5oz.in) and rated current of 1.0A, it offers improved positioning accuracy, enhanced torque, and reduced heat compared to open-loop systems—all within a compact 28mm frame. Ideal for robotics, automation, and miniature motion control setups.
