EY-1002-1-H04AA

The EY-1002-1-H04AA (also referenced as Y-1002-1-H04AA) is a brushless AC servo motor manufactured by Allen‑Bradley (Rockwell Automation), belonging to the Y Series light industrial servo motor lineup. It is engineered for high‑precision motion control in automated machinery, delivering compact size, fast acceleration, and reliable performance for demanding positioning and speed‑regulation tasks.

This model is a 1002‑frame brushless servo motor designed for 230 VAC three‑phase operation, featuring a high‑energy neodymium magnet rotor for rapid dynamic response. It integrates a 2000‑line optical encoder for precise position and velocity feedback, and includes a 24 VDC holding brake to secure the shaft at standstill. The motor’s IP43‑rated enclosure protects against dust and splashed water, making it suitable for general industrial environments. It is fully compatible with Allen‑Bradley Kinetix 2000 and Kinetix 6000 servo drives, forming a complete motion control system for coordinated multi‑axis applications.

The EY-1002-1-H04AA operates on 230 VAC three‑phase power, with a rated speed of 4500 rpm and a maximum radial load capacity of 10 kg. It utilizes an 8‑pole brushless design with neodymium magnets, enabling high torque density and quick acceleration. The integrated encoder provides 2000 lines per revolution, requiring 5 VDC power for operation, and delivers driver data and commutation signals for accurate control. The 24 VDC holding brake is intended for static holding only, not for dynamic stopping or emergency safety functions. The motor has an IP43 enclosure rating, an operating temperature range of 0°C to 40°C, and a thermal resistance of 2.3°C/Watt. It features an IEC metric mounting flange and weighs approximately 0.65 kg, with a compact form factor optimized for space‑constrained installations.

The motor’s brushless design eliminates brush wear and electrical arcing, ensuring long‑term reliability and minimal maintenance. The high‑energy magnet rotor enables exceptional acceleration and deceleration performance, critical for high‑speed positioning applications. The 2000‑line encoder provides precise feedback for closed‑loop control, supporting tight position and velocity regulation. The integrated holding brake enhances safety in vertical or suspended load applications by preventing unintended shaft movement during power outages. The rugged, compact construction resists vibration and shock, suitable for continuous operation in industrial production lines. Compatibility with Allen‑Bradley Kinetix drives simplifies system integration and ensures seamless communication within Rockwell Automation’s motion control ecosystem.

The EY-1002-1-H04AA is widely used in industrial automation applications requiring precise motion control. Typical uses include robotics, packaging machinery, material handling systems, CNC equipment, X‑Y positioning tables, textile machinery, and general factory automation. It is ideal for light‑to‑medium duty applications where compact size, high speed, and accurate positioning are essential, such as assembly lines, pick‑and‑place systems, and automated sorting equipment.

Mount the motor on a rigid, flat surface using the IEC metric flange, ensuring proper alignment with the driven load to avoid excessive bearing stress. Use a rigid coupling to connect the motor shaft to the load, as flexible couplings may slip during rapid acceleration. Verify that the power supply voltage matches the motor’s 230 VAC rating, and connect the encoder and brake wiring according to the manufacturer’s guidelines. During operation, maintain ambient temperatures between 0°C and 40°C and ensure adequate ventilation to prevent overheating. Regularly inspect the motor for unusual noise, vibration, or overheating, and check wiring connections for tightness. Avoid using the holding brake for dynamic stopping, as this can cause premature brake wear. Keep the motor enclosure clean and free of dust and debris to maintain optimal performance and longevity.
