Two-phase 86 Series (1.8°) Closed-loop Stepper Motor

Product Overview

The two-phase 86 series closed-loop stepper motor uses high-quality raw materials and high-grade permanent magnet silicon steel sheets, equipped with a 1000-line high-precision encoder. It completely overcomes the step loss problem of open-loop stepper motors, significantly improves high-speed motor performance, reduces motor heating and vibration, enhances machining speed and accuracy, and lowers machine power consumption. It facilitates the upgrade of traditional stepper drive solutions, with cost reductions of over 50% compared to servo motors. The motor length ranges from 82mm to 176mm, torque range: 3N.m to 12N.m, motor shaft diameter 14mm.

Features

Motor Type: Two-phase closed-loop stepper motor Step Angle: 1.8° Frame Angle: 86 Holding Torque: 3.0~12 N.m Phase Current: 6.0A Encoder: Built-in 1000-line encoder
