Two-phase 42 series (17-bit absolute) closed-loop stepper motor

Product Overview

The two-phase 42 series multi-turn absolute closed-loop stepper motor adopts the design of the LC series, featuring advantages such as high torque, low generation, and good stability. The rear end is equipped with the same 17-bit multi-turn magnetic encoder as the servo motor platform, which provides a stable and reliable position feedback adding a power-off position memory function.
