The MPL-B330P-MJ22AA is a low-inertia permanent-magnet AC rotary servo motor belonging to the MP-Series MPL family. It is designed for high-speed and high-response motion-control applications where accurate positioning, rapid acceleration, stable speed control, and repeatable machine movement are required.
The motor uses a 400 V-class electrical design and is commonly specified for 460 V AC servo systems. With a rated speed of up to 5000 rpm, the MPL-B330P-MJ22AA is intended for applications requiring fast cycling and dynamic movement rather than simple constant-speed motor operation.
The motor has a 100 mm frame size and a 76.2 mm magnetic stack length, providing a relatively compact mechanical package for its torque and speed capability.
The MPL-B330P-MJ22AA uses a multi-turn high-resolution absolute encoder for feedback. This allows the servo control system to monitor motor position and speed accurately during operation and provides the feedback required for closed-loop motion control.
The model is supplied with a keyed shaft extension, a circular bayonet connector facing the shaft, and no integral holding brake. It uses an IEC metric mounting arrangement with free mounting holes.
The design is particularly suitable for machinery where the motor must repeatedly accelerate, decelerate, stop, reverse, and reposition a load with controlled motion accuracy.

The MPL-B330P-MJ22AA uses a 100 mm frame size and a 76.2 mm magnetic stack length.
The 100 mm frame size is the primary dimensional classification of the motor. It is useful when checking motor mounting compatibility, machine-frame clearance, coupling arrangements, and replacement requirements.
The magnetic stack length is 76.2 mm, equivalent to approximately 3.0 inches.
The complete motor envelope includes the front flange, shaft extension, connector area, and rear motor housing. Because the exact mechanical envelope can depend on the particular motor configuration and drawing revision, an overall length should be checked against the mechanical drawing before final installation.

For replacement work, it is important not to select the motor based only on the 100 mm frame dimension. Shaft type, encoder type, connector style, brake configuration, mounting pattern, stack length, and drive compatibility should also be checked.
The MPL-B330P-MJ22AA is a high-voltage-class servo motor intended for use with compatible industrial servo drives.
Its electrical classification is approximately 400 V AC, with 460 V-class servo-system applications commonly associated with this motor family.
The motor is not intended to be connected directly to a standard industrial AC motor starter in the same manner as a conventional induction motor. It is designed to operate as part of a closed-loop servo system in which the servo drive controls motor current, torque, speed, and position.
| Electrical Parameter | Specification |
|---|---|
| Model | MPL-B330P-MJ22AA |
| Motor Type | Permanent-magnet AC servo |
| Voltage Class | 400 V AC |

One of the important characteristics of the MPL-B330P-MJ22AA is its combination of approximately 4.18 N·m continuous torque and 5000 rpm rated speed.
This combination allows the motor to perform rapid positioning movements while still providing useful continuous torque for machine loads.
The low-inertia rotor design also reduces the amount of torque required to accelerate the motor’s own rotating mass. This is particularly useful in applications involving frequent starts, stops, reversals, indexing, and short positioning movements.
Servo motor performance should always be evaluated together with the load inertia, mechanical transmission, duty cycle, acceleration profile, and servo-drive settings.

The MPL-B330P-MJ22AA uses a multi-turn high-resolution absolute encoder.
The encoder provides the servo controller with motor position and speed information. This feedback is essential for accurate closed-loop control.
The multi-turn function is particularly useful for machinery that needs to retain rotational position information across multiple motor revolutions.
The encoder also allows the servo drive to continuously compare commanded motion with actual motor movement. This supports accurate positioning and controlled acceleration and deceleration.

| Feedback Type | Absolute encoder |
| Encoder Function | Multi-turn |
| Resolution Class | High-resolution |
| Feedback Application | Position, speed and motion control |

The motor is equipped with a keyed shaft extension.
A keyed shaft is useful when the motor is connected to a coupling, pulley, gearbox, timing mechanism, or other mechanical transmission component designed for a keyed connection.
The shaft does not include an integral shaft seal. When the motor is installed in an environment where contamination, moisture, oil, or washdown exposure may occur, the complete machine sealing arrangement should therefore be considered carefully.
The coupling should be correctly aligned with the motor shaft. Excessive radial or axial loading can reduce bearing life and negatively affect servo performance.
The MPL-B330P-MJ22AA uses a circular bayonet connector positioned facing the shaft.
The bayonet-style connection provides a positive mechanical connection between the motor and its associated motor/feedback cabling.
When replacing an existing motor, the connector configuration should be checked carefully. Two motors from the same MPL family can have similar electrical ratings while using different connector arrangements.
| Connector Parameter | Specification |
|---|---|
| Model | MPL-B330P-MJ22AA |
| Connector Type | Circular bayonet |
| Connector Orientation | Facing shaft |
| Motor Connection | Servo motor power/feedback system |
| Cable Consideration | Use compatible motor and feedback cabling |
| Installation Requirement | Maintain adequate connector clearance |
| Maintenance Requirement | Check connector locking, contamination and cable condition |
The MPL-B330P-MJ22AA is a non-braked configuration.
This means the motor does not include an integral holding brake.
For applications involving vertical axes, suspended loads, or machinery that must remain mechanically stationary after servo power is removed, the machine designer may need to provide a separate mechanical holding solution or select a motor configuration with an integral brake.
The absence of a brake can also be advantageous in applications where the motor does not need to provide holding torque when disabled and where minimizing rotating or stationary motor components is important.
| Brake Parameter | Specification |
|---|---|
| Model | MPL-B330P-MJ22AA |
| Integral Brake | No |
| Brake Voltage | Not applicable |
| Holding Function | Not provided internally |
| Vertical Axis Application | Requires separate holding strategy if required |
| Emergency Stop Consideration | Machine-level safety design required |
The MPL-B330P-MJ22AA is part of the MPL low-inertia servo motor family.
Low rotor inertia is important for high-dynamic motion applications because the servo system does not have to spend as much torque accelerating the motor rotor itself.
This can improve acceleration response and allow the motor to change speed rapidly.
The advantage becomes particularly noticeable in machines that perform repetitive indexing or rapid reciprocating movement.
Typical examples include packaging equipment, pick-and-place mechanisms, electronic assembly machinery, converting equipment, and high-speed positioning systems.
The 5000 rpm rated speed makes the MPL-B330P-MJ22AA suitable for applications where rapid motor movement and short machine cycle times are important.
The high-speed capability is particularly useful for rotary mechanisms, indexing systems, high-speed feeding equipment, and compact transmission systems.
The low-inertia design supports fast acceleration and deceleration.
This allows the servo system to respond quickly to command changes and is useful for machinery with frequent speed changes.
The multi-turn absolute encoder provides detailed position feedback to the servo system.
This supports accurate positioning and repeatable machine movement.
The 100 mm frame size provides a useful combination of torque capability and relatively compact mechanical dimensions.
This makes the motor suitable for machinery where installation space is limited but a higher-performance servo motor is required.
The keyed shaft provides a conventional mechanical interface for compatible couplings, pulleys, gearboxes, and other transmission components.
The IEC metric mounting arrangement is convenient for machinery designed around metric mechanical standards.
The approximately 1.8 kW rating places the motor in a useful range for many industrial motion applications, particularly where speed and dynamic response are more important than very high continuous torque.
The MPL-B330P-MJ22AA is well suited to packaging equipment requiring synchronized movement, rapid indexing, feeding, cutting, sealing, or product positioning.
Typical mechanisms include film feeding systems, rotary indexing stations, product conveyors, label handling systems, and packaging-axis positioning mechanisms.
The combination of high speed and low inertia is useful for repetitive machine cycles.
The motor can be used for controlled movement in material-handling machinery.
Applications can include conveyor positioning, transfer mechanisms, indexing units, pick-and-place systems, and automated handling equipment.
The servo system can regulate speed and position according to the machine sequence.
Electronic assembly machines often require precise and repeatable movement.
The MPL-B330P-MJ22AA can be applied to positioning axes, feeder mechanisms, indexing systems, component handling, and other machine movements where repeatability and dynamic response are important.
Printing and converting machinery can require rapid acceleration, deceleration, synchronized movement, and accurate position control.
The high-speed capability of this motor makes it suitable for selected web-handling and rotary-motion applications when correctly matched with the machine’s load and transmission.
The motor can be used in auxiliary machine-tool axes and positioning mechanisms where closed-loop servo control is required.
The exact suitability depends on the axis load, acceleration requirements, mechanical transmission, duty cycle, and servo-drive configuration.
General automated production machinery can use the MPL-B330P-MJ22AA for indexing, positioning, rotary motion, material transfer, and coordinated machine-axis movement.
The motor is particularly useful when the machine requires repeated and accurately controlled motion rather than simple constant-speed rotation.
| Application Requirement | MPL-B330P-MJ22AA Characteristic |
|---|---|
| High-speed motion | 5000 rpm rated speed |
| Rapid acceleration | Low-inertia rotor |
| Accurate positioning | Absolute encoder feedback |
| Repetitive indexing | Servo-controlled motion |
| Compact installation | 100 mm frame |
| Moderate machine power | Approximately 1.8 kW |
| Conventional mechanical coupling | Keyed shaft |
| Metric machine construction | IEC metric mounting |
| High-cycle machinery | Brushless servo construction |
| Multi-revolution position feedback | Multi-turn absolute encoder |
Before installation, the motor should be checked against the servo drive, mechanical load, mounting arrangement, shaft configuration, connector arrangement, and feedback requirements.
The motor should not be selected solely by comparing horsepower or kilowatt ratings.
The servo drive must be compatible with the motor’s voltage class and feedback system.
The mechanical coupling should be correctly aligned, and the load should remain within the motor’s allowable radial and axial loading limits.
Cable routing should prevent excessive bending, pulling, twisting, or mechanical stress at the motor connector.
The connector should remain clean and properly secured during operation.
Because this version does not contain an integral holding brake, vertical-axis applications require particular attention to load holding and machine safety.
Routine maintenance should include inspection of motor mounting bolts, coupling alignment, shaft condition, cables, connectors, machine vibration, and abnormal temperature rise.
The encoder connection should be kept secure and free from contamination.
The motor should be monitored for unusual noise or vibration. Changes in vibration can indicate mechanical misalignment, bearing wear, coupling problems, or load-related issues.
Servo-drive alarms should also be reviewed when abnormal machine behavior occurs.
A motor that operates normally under one load may show different thermal or dynamic characteristics under another load, so maintenance should consider the complete mechanical system rather than the motor alone.
When replacing another MPL motor with the MPL-B330P-MJ22AA, several details should be compared.
The frame size should be checked first, followed by stack length, mounting arrangement, shaft type, shaft dimensions, connector configuration, feedback type, brake configuration, and motor-drive compatibility.
A motor with the same frame size is not automatically a direct replacement.
The MJ22AA configuration is particularly important because it specifies a combination involving the multi-turn absolute encoder, keyed shaft, circular bayonet connector, and no integral brake.
For this reason, suffix differences between MPL motors should not be ignored during replacement work.

The MPL-B320P provides a step upward in torque and power while retaining the 5000 rpm operating class.
The MPL-B330P-MJ22AA represents the 100 mm-frame class and provides approximately 4.18 N·m of continuous torque.
The MPL-B420P provides slightly higher continuous torque while remaining within a similar general performance category.
The MPL-B430P provides a higher torque and power level for applications requiring additional motor capacity.
The following Allen-Bradley models are useful for comparison when selecting motors for industrial motion systems. They cover different MPL motor sizes and performance levels.

These models provide a useful range for comparing motor torque, speed, frame size, and machine power requirements.
The MPL-B330P-MJ22AA is positioned between the smaller B320P class and the higher-output B420P/B430P classes.
The larger B4560F configuration is intended for substantially higher torque requirements and uses a larger mechanical package.
The MPL-B330P family contains several suffix variations. The basic motor size and performance class can be similar while the feedback, connector, shaft, or brake configuration changes.
| Model | Speed | Continuous Torque | Feedback Type | Shaft | Brake | Connector / Configuration |
|---|---|---|---|---|---|---|
| MPL-B330P-MJ22AA | 5000 rpm | Approx. 4.18 N·m | Multi-turn absolute | Keyed | No | Circular bayonet, facing shaft |
| MPL-B330P-MJ24AA | 5000 rpm | Approx. 4.18 N·m | Multi-turn absolute | Keyed | Yes | Related braked configuration |

| MPL-B330P-HJ22AA | 5000 rpm | Approx. 4.18 N·m | Encoder configuration | Keyed | No | Related feedback configuration |
The table illustrates why the complete catalog number is important.
For example, changing the encoder type can affect drive configuration, feedback wiring, commissioning, and replacement compatibility even when the motor frame and torque rating are similar.
The main engineering value of the MPL-B330P-MJ22AA is the combination of speed, torque, low rotor inertia, and absolute feedback.
A conventional motor may provide sufficient rotational power but may not provide the same positioning response required by an automated machine.
The servo motor is designed around controlled motion. The motor, encoder, servo drive, controller, and mechanical transmission operate together as a closed-loop system.
The controller commands the required movement, the servo drive controls motor current, and the encoder provides actual position and speed information.
This arrangement makes the motor suitable for machines that repeatedly execute programmed motion profiles.
For machine builders, the 100 mm frame size provides a useful mechanical package for integrating a servo motor into a machine axis.
The keyed shaft provides a familiar mechanical interface.
The multi-turn absolute feedback configuration is suitable for motion systems requiring detailed position information.
The 5000 rpm speed rating supports high-speed machine cycles.
The low-inertia design supports rapid changes in motor speed.
The approximately 1.8 kW power class also provides a practical balance between compact motor construction and useful machine-axis output.
The MPL-B330P-MJ22AA is relatively straightforward to identify because the complete catalog number describes a specific combination of motor characteristics.
When replacing the motor, technicians should compare the full catalog number rather than selecting a motor based only on the MPL-B330P prefix.
The most important replacement checks include:
These checks help prevent mechanical installation problems and incorrect feedback configuration.
The MPL-B330P-MJ22AA is a 400 V-class, 5000 rpm, low-inertia brushless servo motor in the MP-Series MPL family.
It uses a 100 mm frame, 76.2 mm magnetic stack, approximately 4.18 N·m continuous torque, and approximately 1.8 kW rated power.
Its multi-turn absolute encoder provides closed-loop feedback for position and speed control.
The keyed shaft makes it suitable for conventional mechanical transmission arrangements.
The motor does not include an integral brake, so applications requiring stationary holding after servo power removal must provide an appropriate external holding method or use a braked motor configuration.
The motor is particularly suited to packaging, material handling, electronic assembly, indexing, converting, printing-related mechanisms, and general automated production machinery.

The Allen-Bradley MPL-B330P-MJ22AA is a high-speed, low-inertia servo motor designed for industrial automation systems requiring accurate and repeatable motion.
Its 5000 rpm speed rating, approximately 4.18 N·m continuous torque, approximately 1.8 kW power rating, 100 mm frame, and multi-turn absolute encoder make it suitable for a wide range of machine-axis applications.
The motor’s low-inertia construction is particularly useful for machines that repeatedly accelerate and decelerate. Its absolute feedback system provides the information required for accurate closed-loop motion control.
The keyed shaft provides a conventional mechanical connection, while the circular bayonet connector provides the motor-side electrical interface.
Because the MJ22AA configuration does not include an integral brake, it is especially appropriate for non-braked axes where the machine’s mechanical design does not require the motor itself to provide holding force after power removal.
For replacement or retrofit work, the complete catalog number should always be matched against the existing motor and servo-drive configuration. Frame size alone is not sufficient to establish interchangeability.
In practical industrial use, the MPL-B330P-MJ22AA is best understood as a 100 mm-frame, 5000 rpm, low-inertia servo motor with approximately 1.8 kW output, approximately 4.18 N·m continuous torque, keyed shaft, multi-turn absolute feedback, and no integral brake.
This combination makes it a suitable choice for demanding automated machinery where fast response, repeatable positioning, compact mechanical installation, and reliable closed-loop motion are important.
