Two-phase 57 series (17-bit absolute) closed-loop stepper motor

Product Overview

The two-phase 57 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.

Features

Motor Type: 17-bit absolute‑value closed-loop stepper motor Step Angle: 1.8° Frame Size: 57 mm Holding Torque: 1.2–3.5 N·m Phase Current: 4.0–5.0 A Encoder: Built-in 17-bit multi-turn magneto‑electric absolute encoder Features: Low heat generation, high stability
