The Allen Bradley MPL-B330P-HJ74AA belongs to the MP-Series MPL family of low-inertia brushless servo motors. Its 100 mm frame and 76.2 mm magnet stack provide a substantial motor configuration for industrial motion applications requiring reliable closed-loop control.
The motor operates in the 460 V AC class and provides a 5000 RPM rated speed. Its 2000-line incremental encoder supplies position and speed feedback to the associated servo drive, allowing the control system to regulate motor movement accurately.
A major feature of the HJ74AA configuration is its 24 V DC holding brake. Compared with the brake-free HJ72AA version, this configuration is better suited to applications where the motor must hold its shaft against movement while the servo is stopped.
The keyed shaft extension, IEC metric mounting, and right-angle SpeedTEC DIN connector provide practical mechanical and electrical integration options for compatible machine designs.
For maintenance and retrofit projects involving legacy MP-Series equipment, the MPL-B330P-HJ74AA should be matched carefully with the existing drive, feedback system, mechanical load, and brake requirements.

When selecting a replacement for the MPL-B330P-HJ74AA, verify the 460 V AC voltage class, 100 mm frame, 76.2 mm stack, 5000 RPM rated speed, 2000-line incremental encoder, and 24 V DC holding brake. These parameters are essential for maintaining electrical, mechanical, and motion-control compatibility.
Industrial Motion Control Applications
The MPL-B330P-HJ74AA is suitable for automated equipment where precise rotary motion, repeatable positioning, and controlled acceleration are required.
Common applications include:
Packaging and filling machinery
Automated assembly equipment
Material handling systems
Conveyor positioning
Printing and converting machinery
Machine tools
Pick-and-place equipment
Automated inspection systems
Production machinery
Robotics and auxiliary motion axes
High-speed indexing equipment
Industrial machine upgrades and maintenance
The integrated holding brake also makes this configuration useful for applications where the motor shaft needs to remain mechanically held when the servo is stopped.
Key Performance Advantages
Low-Inertia Brushless Design
The low-inertia brushless construction provides responsive acceleration and deceleration, helping the motor handle repetitive positioning and speed-change cycles.
5000 RPM Rated Speed
The motor provides a rated speed of 5000 RPM, offering a balance between high-speed operation and controlled servo performance for industrial machinery.
2000-Line Incremental Encoder
The integrated incremental encoder supplies position and speed feedback to the servo drive, supporting closed-loop motion control.
100 mm Frame Size
The 100 mm frame provides a larger motor configuration for machinery requiring greater mechanical capacity than smaller MPL servo motor frames.
24 V DC Holding Brake
The HJ74AA version includes an integrated 24 V DC brake. The brake can help hold the motor shaft when active servo torque is unavailable.
Keyed Shaft Extension
The keyed shaft provides a secure connection for compatible couplings, pulleys, gears, and other mechanical transmission components.
Right-Angle SpeedTEC DIN Connector
The right-angle connector arrangement provides flexibility when routing motor cables through compact machine assemblies and can be rotated to suit installation requirements.
