no encoder

Helix Linear Technologies' BSA-14-E Double Stack Flanged Ball Screw Stepper Motor Actuators without encoder integrate a NEMA 14 double stack bipolar stepper motor with a precision 8 mm diameter ball screw and flanged ball nut for high-torque, accurate open-loop linear motion in a compact form factor. Available in 5 mm and 8 mm lead options with optional 8N end machining for robotics, medical devices, semiconductor, and compact automation applications where open-loop position control is sufficient. U.S.-made.
