The Allen Bradley MPL-B330P-HK72AA 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 configuration for industrial motion applications requiring accurate and repeatable rotary movement.
The motor operates in the 460 V AC class and has a 5000 RPM rated speed. A 2000-line incremental encoder provides feedback to the servo drive, allowing the control system to monitor motor movement and regulate speed and position.
A distinguishing feature of the HK72AA configuration is its keyless shaft extension. This differs from keyed-shaft MPL variants and should be considered carefully when selecting mechanical couplings or replacing an existing motor.
The motor also has no integrated brake. For applications that require shaft holding, a brake-equipped model such as the related HK74AA configuration should be evaluated.
The MPL-B330P-HK72AA has been discontinued by Rockwell Automation, with MPL-B330P-SK72AA identified as an engineering replacement. For legacy equipment, the original model remains relevant for maintenance and replacement purposes, but all electrical and mechanical characteristics should be checked before substitution.

When replacing the MPL-B330P-HK72AA, particular attention should be given to the 460 V AC voltage class, 100 mm frame, 76.2 mm magnet stack, 5000 RPM rating, 2000-line incremental encoder, keyless shaft, and no-brake configuration. These characteristics should match the existing motion-control and mechanical system before installation.
Industrial Motion Control Applications
The MPL-B330P-HK72AA is suitable for automated machinery where controlled rotary movement and repeatable positioning are essential.
Typical applications include:
Packaging and filling machinery
Automated assembly systems
Material handling equipment
Conveyor positioning
Printing and converting machinery
Machine tools
Pick-and-place systems
Automated inspection equipment
Electronics manufacturing
High-speed indexing machinery
Production-line automation
Industrial machine retrofits and maintenance
Its 5000 RPM operating capability and incremental encoder feedback make it suitable for applications requiring continuous closed-loop speed and position control.
Key Performance Advantages
Low-Inertia Brushless Construction
The MPL-B330P-HK72AA uses a low-inertia brushless servo design that supports rapid acceleration and deceleration. This is useful for machinery with frequent speed changes and repetitive motion cycles.
100 mm Frame Configuration
The 100 mm frame provides a robust mechanical platform for applications requiring a larger servo motor than compact MPL configurations.
76.2 mm Magnet Stack
The 30-series magnet stack provides a 76.2 mm active motor stack, forming part of the motor's torque and performance configuration.
5000 RPM Rated Speed
The motor is designed for a rated speed of 5000 RPM, supporting high-speed automated machinery and positioning applications.
2000-Line Incremental Encoder
The integrated 2000-line incremental encoder provides position and speed feedback to the associated servo drive for closed-loop control.
Keyless Shaft Extension
Unlike keyed MPL configurations, the HK72AA uses a keyless shaft extension. The mechanical coupling method should therefore be matched to the shaft design during machine integration or replacement.
No Integrated Brake
The HK72AA configuration does not include a holding brake. This is appropriate for applications where mechanical shaft holding is not required.
Flexible SpeedTEC DIN Connector
The right-angle SpeedTEC DIN connector can be rotated through 180 degrees, helping simplify cable routing and installation in confined machine spaces.
