Introduction

The Allen-Bradley MPL-A210V-HJ72AA MP-Series MPL 240V AC Rotary Servo Motor is a low-inertia brushless servo motor designed for industrial automation and precision motion-control applications. Its 75 mm frame and 25.4 mm magnet stack provide a compact motor platform for machines that require responsive rotary motion.

The motor has a 3500 RPM rated speed, making it suitable for applications where controlled speed, positioning accuracy, and dynamic response are more important than extremely high rotational speed. Compared with higher-speed MPL configurations, the HJ72AA is well suited to machinery requiring a practical combination of speed and torque.

A key feature of this model is its 2000-line incremental encoder. The encoder provides position and speed feedback to a compatible servo drive, allowing the motion-control system to regulate motor operation in a closed-loop configuration. This is important for applications such as indexing, positioning, coordinated motion, and automated production equipment.

The motor uses a keyed shaft extension. This mechanical configuration provides a positive connection for suitable couplings, pulleys, gears, and other driven components. Proper shaft alignment and appropriate mechanical loading should be maintained during installation to help protect the motor bearings and ensure stable operation.

The SpeedTEC DIN right-angle connector provides additional flexibility during machine installation. Its 180-degree rotational capability allows the connector orientation to be adjusted according to available space and cable-routing requirements.

The HJ72AA configuration is supplied without a motor brake. This should be considered carefully when selecting the motor for vertical axes or applications where the load must remain mechanically held after servo power is removed. Where a brake is required, a compatible MPL configuration with the appropriate brake option should be selected.

The motor uses IEC metric mounting with free mounting holes, allowing it to be installed on compatible machine structures. The compact 75 mm frame is useful for automation equipment where cabinet and machine-space requirements are important.

For replacement applications, the complete catalog number MPL-A210V-HJ72AA should be verified. Other MPL-A210V motors can have different speeds, feedback systems, brake options, and other configuration characteristics. Matching the complete catalog number helps ensure that the replacement motor has the required electrical, mechanical, and feedback characteristics.
