The Allen Bradley MPL-B330P-HJ72AA is part of the MP-Series MPL family of low-inertia brushless servo motors. Its 100 mm frame and 76.2 mm magnet stack provide a substantial mechanical configuration for industrial motion applications requiring controlled rotary movement.
The motor operates in the 460 V AC class and provides a 5000 RPM rated speed. Its 2000-line incremental encoder supplies feedback to the motion-control system, allowing the servo drive to regulate motor speed and position in a closed-loop configuration.
The keyed shaft extension provides a dependable mechanical connection, while the SpeedTEC DIN right-angle connector offers flexibility for cable routing. The HJ72AA configuration does not include a brake, which should be considered when evaluating the motor for vertical axes or other load-holding applications.
Rockwell Automation lists the MPL-B330P-HJ72AA as discontinued, with the MPL-B330P-SJ72AA identified as an engineering replacement. For existing equipment, the original HJ72AA remains useful as a maintenance and replacement reference, but the replacement should be evaluated for complete system compatibility.

Key Performance Advantages
Low-Inertia Brushless Construction
The MPL-B330P-HJ72AA uses a low-inertia brushless servo design for responsive acceleration and deceleration. This is beneficial for machinery with frequent speed changes and repetitive positioning cycles.
5000 RPM Rated Speed
The motor is designed for a rated speed of 5000 RPM, providing a useful combination of rotational speed and servo control performance for industrial machinery.
2000-Line Incremental Encoder
The integrated 2000-line incremental encoder supplies motor feedback to the servo drive, supporting closed-loop speed and position control.
100 mm Frame Size
The 100 mm frame provides a larger mechanical platform than compact MPL motors, making this model suitable for applications requiring a higher-capacity servo motor configuration.
76.2 mm Magnet Stack
The 30-series stack length corresponds to a 76.2 mm magnet stack, providing the motor configuration required for its rated torque and power characteristics.
Keyed Shaft Extension
The keyed shaft allows compatible couplings, gears, pulleys, and other mechanical transmission components to be securely connected to the motor.
Flexible SpeedTEC DIN Connector
The right-angle SpeedTEC DIN connector can be rotated to accommodate different machine layouts and cable-routing requirements.
No-Brake Configuration
The HJ72AA configuration does not include an integrated holding brake. This makes it suitable for applications where a motor brake is not required.
