Product Overview
The Allen-Bradley MPL-A220T-EJ74AA Servo Motor is a high-performance MP-Series Low-Inertia 230V AC Rotary Servo Motor designed for precision motion control in demanding industrial automation systems. As part of the Rockwell Automation MP-Series servo motor family, this model delivers excellent positioning accuracy, fast dynamic response, and smooth torque output for high-speed machine applications. Unlike the MPL-A220T-EJ72AA, the MPL-A220T-EJ74AA is equipped with an integrated 24 V DC holding brake, making it particularly suitable for vertical-axis applications and machinery requiring secure load holding during power loss or emergency stops.
The motor features a 75 mm IEC metric frame size, 230 V AC operation, 6000 RPM rated speed, 50.8 mm magnet stack length, single-turn high-resolution encoder, keyed shaft, and a SpeedTEC right-angle rotatable DIN connector for quick installation and reliable electrical connections. Its low-inertia rotor provides rapid acceleration and deceleration, helping reduce machine cycle times while maintaining exceptional motion accuracy.
Designed for seamless integration with Allen-Bradley Kinetix servo drives, the MPL-A220T-EJ74AA is widely used in packaging machinery, robotic systems, CNC equipment, electronic assembly machines, semiconductor manufacturing, pharmaceutical production, printing machinery, and precision material handling equipment.
With a compact 75 mm frame size and an approximate weight of 2 kg, the servo motor offers high power density while minimizing installation space requirements.
