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.
Note: The "H21" suffix typically indicates specific shaft dimensions (keyway + threaded hole) and connector orientation.
Core Features & Benefits
High Overload Capacity: Supports up to 300% peak torque, enabling handling of sudden load fluctuations and high acceleration starts without stalling.
High Precision Control: Equipped with a 2500-line incremental encoder, ensuring high resolution for precise positioning in CNC and pick-and-place applications.
Rugged Design: IP65 protection rating makes it resistant to dust and water jets, suitable for harsh workshop environments like woodworking or textile machinery.
Compact & Efficient: The 400W frame size allows for installation in space-constrained equipment while maintaining high thermal efficiency.
Applications
The Estun EMJ-04APH21 is engineered for high-cycle industrial automation, specifically excelling in:
Textile Machinery: High-speed winding and precise yarn laying
Electronics Assembly: Small PCB drilling machines and pick-and-place heads
Packaging Machinery: Labeling machines and small conveyor indexing drives
General Automation: 3D printers (industrial grade), robotic arms (small payload), and automatic tool changers
Why Choose Estun EMJ-04APH21?
In the competitive 400W servo market, the EMJ series stands out for its value engineering and reliability.
Compatibility: Shares standard flange dimensions (60mm or 80mm frame) with other Asian market motors, making mechanical replacement easy
Integration: Pairs seamlessly with Estun ProNet series drives or EtherCAT models, ensuring plug-and-play functionality
Global Support: Standard 1-year manufacturer warranty and global shipping via DHL/FedEx
Shipping & Support
Global Shipping: Fast shipping from regional warehouses (subject to stock)
Documentation: Datasheets, CAD drawings, and wiring diagrams available upon request
