Description
Estun EMJ-04APH21 0.4kW High Torque AC Servo Motor for Industrial Automation
Product Overview

The Estun EMJ-04APH21 is a high-performance AC servo motor from the Estun EMJ series, designed for precise speed and position control in demanding industrial environments. With a rated power of 400W (0.4kW), this model is optimized for applications requiring high torque density and rapid dynamic response.

This motor integrates a 2500 P/R incremental encoder (supports serial absolute encoder upgrade), ensuring stable operation even at near-zero speeds. As a cost-effective alternative to European or Japanese brands, the EMJ-04APH21 delivers excellent value without compromising on build quality or performance.
