The MPL-B330P-MJ74AA combines a compact 100 mm frame with the high-speed performance expected from the MP-Series low-inertia servo family. Its 76.2 mm magnet stack, 1.8 kW continuous rated power, 4.18 Nm continuous torque, and 5000 RPM speed rating make it suitable for machines requiring responsive and repeatable axis movement.
The multi-turn absolute encoder is an important part of the motor's control architecture. It provides high-resolution position feedback and allows the servo system to monitor the motor's position across multiple revolutions.
The MJ74AA configuration is also clearly distinguished by its keyed shaft, multi-turn feedback, and 24 V DC brake. These details are important when selecting a replacement because closely related MPL-B330P models can have different shaft, feedback, and brake configurations.

Key Performance Advantages
Low-inertia servo construction
The MP-Series low-inertia design helps the motor respond quickly to changes in speed and position commands, making it appropriate for dynamic machine axes.
Multi-turn absolute feedback
The high-resolution absolute encoder provides position information over multiple revolutions. This supports precise closed-loop motion control and repeatable positioning.
5000 RPM speed capability
The motor is rated for 5000 RPM, making it suitable for high-cycle machinery and applications where rapid axis movement is required.
4.18 Nm continuous torque
The MPL-B330P-MJ74AA provides 4.18 Nm of continuous torque and 11.1 Nm peak torque, giving the motor useful dynamic capability for demanding machine movements.
Integrated 24 V DC brake
The built-in holding brake provides mechanical shaft holding when required. It is particularly useful on vertical or gravity-loaded axes.
Keyed shaft extension
The keyed shaft provides a positive mechanical connection for compatible couplings and driven components.
Flexible connector arrangement
The SpeedTEC DIN right-angle connector can be rotated through 180 degrees, giving machine designers additional flexibility when routing motor cables.
Technical FAQs
1. What type of servo motor is the MPL-B330P-MJ74AA?
It is an Allen Bradley MP-Series low-inertia brushless rotary servo motor intended for closed-loop industrial motion control.
2. What is the voltage rating of the MPL-B330P-MJ74AA?
The motor has a 460 V AC armature-voltage rating and belongs to the 400 V AC voltage class.
3. What is the rated speed of this servo motor?
The MPL-B330P-MJ74AA has a rated speed of 5000 RPM. Its maximum listed speed is also 5000 RPM.
4. What feedback device is installed in the motor?
The motor uses a multi-turn high-resolution absolute encoder with Sin/Cos feedback and Hiperface protocol. This provides detailed position feedback for the servo-control system.
5. Does the MPL-B330P-MJ74AA have a holding brake?
Yes. It includes an integrated 24 V DC holding brake. The brake is intended primarily for holding the shaft/load rather than replacing the servo drive's normal controlled stopping function.
6. Does this model use a keyed shaft?
Yes. The MPL-B330P-MJ74AA has a keyed shaft extension and no shaft seal in its standard configuration.
7. What is the magnet stack length?
The motor has a 30-series magnet stack measuring 76.2 mm, or 3.0 inches.
8. Which servo drives are compatible with the MPL-B330P-MJ74AA?
Compatible Allen Bradley motion platforms include Kinetix 5500, Kinetix 6200/6500, Kinetix 6000, Kinetix 300, Kinetix 350, Kinetix 2000, Kinetix 7000, and Ultra 3000, subject to the complete motor and drive configuration.
9. What are the continuous and peak torque ratings?
The continuous torque rating is 4.18 Nm, while the peak torque rating is 11.1 Nm.
10. What should be checked before replacing an existing servo motor with the MPL-B330P-MJ74AA?
The voltage class, feedback technology, shaft configuration, brake option, frame size, magnet stack length, connector arrangement, speed rating, and servo-drive compatibility should all be verified. Matching only the frame size is not sufficient to establish electrical and control compatibility.
