MPL-B330P-MK72AA Low-Inertia Servo Motor – Detailed Product Description and Technical Specifications

1. Product Overview

The MPL-B330P-MK72AA is a low-inertia brushless AC rotary servo motor belonging to the MP-Series MPL family. It is designed for high-speed, high-response motion control applications where accurate positioning, rapid acceleration and deceleration, and repeatable dynamic performance are required.

This model uses a 100 mm metric frame, a 76.2 mm magnet stack, a rated speed of 5000 rpm, and a continuous output torque of 4.18 Nm. The motor has a continuous rated output of approximately 1.8 kW and a peak torque capability of 11.1 Nm.

The MPL-B330P-MK72AA uses an absolute multi-turn high-resolution encoder with 1024 Sin/Cos cycles per revolution and Hiperface feedback protocol. This feedback arrangement allows the servo system to continuously monitor motor position and speed for closed-loop motion control.

Unlike brake-equipped versions, this particular model is configured without an integral holding brake. It also uses a keyless shaft extension, making it different from keyed-shaft variants within the same MPL-B330P family.

The motor is equipped with a right-angle SpeedTEC DIN connector. The connector can be rotated through 180 degrees, providing additional flexibility when routing motor cables inside a machine enclosure.

The 100 mm frame dimension is one of the most important mechanical identification points for this motor. The 76.2 mm magnet stack length identifies the active motor stack configuration.

The complete external envelope should not be estimated only from the frame size and stack length. The shaft extension, connector arrangement, flange, rear feedback assembly, and other mechanical features contribute to the final installed dimensions. For machine design, the manufacturer’s dimensional drawing should therefore be used for the exact mounting envelope.

---

4. Torque and Power Characteristics

The MPL-B330P-MK72AA provides approximately 4.18 Nm of continuous torque and 11.1 Nm of peak torque.

The continuous torque rating represents the motor’s ability to produce sustained torque under the specified operating conditions. The higher peak torque rating is intended for short-duration acceleration, deceleration, positioning, and transient load requirements.

Performance Parameter	Value
Continuous Torque	4.18 Nm
Peak Torque	11.1 Nm
Rated Speed	5000 rpm
Continuous Power	1.8 kW
Rotor Inertia	0.00012 kg·m²
Frame Size	100 mm
Magnet Stack	76.2 mm
Weight	Approx. 4.72 kg

The combination of 4.18 Nm continuous torque and 5000 rpm rated speed places this motor in the medium-capacity portion of the MPL low-inertia family.

Its 11.1 Nm peak torque provides additional acceleration capability when properly matched with the servo drive, mechanical load, duty cycle, and thermal conditions.

---

5. Low-Inertia Motor Design

The MPL series is designed around a low-inertia motor construction. Low rotor inertia is particularly useful in applications where the motor must change speed quickly.

A lower rotor inertia means that the servo drive does not have to overcome as much internal rotational inertia when accelerating the motor. This can improve the dynamic response of the complete motion system, particularly when the driven load is also relatively low in inertia.

Typical applications include indexing, pick-and-place equipment, packaging mechanisms, electronic assembly equipment, high-speed material handling, and other machines requiring frequent motion changes.

The MPL-B330P-MK72AA has a published rotor inertia of approximately 0.00012 kg·m², making inertia matching an important consideration when selecting the motor for a particular mechanical system.

---

6. Encoder and Feedback System

The motor incorporates an absolute multi-turn high-resolution encoder.

The published feedback specification identifies a resolution of 1024 Sin/Cos cycles per revolution and a Hiperface feedback protocol.

The encoder provides the servo drive with motor position and speed information. This feedback is fundamental to closed-loop servo control because the drive uses the measured motor position and velocity to regulate the commanded motion.

The absolute multi-turn capability is particularly useful in applications where the control system needs reliable position information over multiple motor revolutions.

Feedback Parameter	Specification
Feedback Type	Absolute multi-turn encoder
Resolution	1024 Sin/Cos cycles/rev
Protocol	Hiperface
Feedback Function	Position and speed monitoring
Control Type	Closed-loop servo control
Application	High-speed positioning and synchronized motion

For machine builders, encoder compatibility is an important selection point. The motor and servo drive must be matched according to the supported feedback interface, motor family, firmware requirements, and system architecture.

---

7. Keyless Shaft Design

One of the most important differences between MPL-B330P-MK72AA and some other MPL-B330P configurations is the shaft design.

This model is specified with a keyless shaft extension.

A keyless shaft can be advantageous where the machine designer uses a suitable clamping hub, shrink disc, precision coupling, or other shaft connection method designed for a smooth servo shaft.

The absence of a shaft key does not mean that the motor is intended to be connected directly to a load without proper mechanical coupling. The coupling must be correctly selected for torque, speed, radial load, axial load, alignment, and acceleration requirements.

---

8. No Integral Brake

The MPL-B330P-MK72AA is a no-brake configuration.

This is important when selecting the motor for vertical axes, lifting systems, gravity-loaded mechanisms, or machines that require a mechanical holding function when power is removed.

Because this model does not include an integral holding brake, the machine designer must determine whether an external mechanical brake or another load-holding method is required.

For horizontal axes and many rotary applications, a brake may not be necessary. For vertical axes, however, the load-holding requirements should be evaluated separately from the servo motor’s dynamic braking or regenerative capabilities.

---

9. Connector Configuration

The motor uses a SpeedTEC DIN connector in a right-angle configuration.

The connector is designed to provide flexibility during machine integration, especially where cabinet space, cable routing, and motor orientation are important.

The connector can be rotated through approximately 180 degrees, allowing the cable exit direction to be adjusted to suit the machine layout.

Connector Parameter	Specification
Connector Family	SpeedTEC DIN
Configuration	Right-angle
Rotation	180° rotatable
Connection Purpose	Motor power/feedback system interface
Installation Benefit	Flexible cable routing
Machine Integration	Suitable for compact servo motor installations

This type of connector arrangement can reduce interference with adjacent machine components and simplify cable routing around the motor.

---

10. Mechanical Dimensions

The most important published dimensional information for the motor is its 100 mm frame size and 76.2 mm magnet stack length.

Mechanical Dimension	Specification
Frame Size	100 mm
Frame Classification	Frame 3
Magnet Stack Length	76.2 mm
Magnet Stack	3.0 in
Mounting Standard	IEC metric
Mounting Flange	Metric flange
Mounting Hole Style	Type FF, free mounting holes
Shaft	Keyless
Shaft Seal	No
Connector	Right-angle SpeedTEC DIN
Overall Length	Refer to exact mechanical drawing
Installed Envelope	Depends on shaft and connector configuration

The 100 mm frame is a useful first-stage dimensional reference when checking compatibility with an existing machine.

However, the 100 mm frame size should not be interpreted as the complete outside diameter or complete motor length. For an accurate mechanical replacement, the flange, bolt pattern, shaft extension, shaft diameter, rear connector arrangement, and overall length must all be checked.

---

11. Weight

The published product information for this specific model lists a weight of approximately 4.72 kg.

Some technical tables for the broader MPL-B330P family list approximately 4.6 kg for a standard B330P configuration, while distributor listings for the specific MK72AA model show approximately 4.72 kg.

For equipment layout and shipping calculations, approximately 4.72 kg can be used as a practical reference for this specific model, while the exact packaged weight should be verified separately if required.

Weight Item	Approximate Value
Motor Weight	4.72 kg
Weight in Pounds	Approx. 10.4 lb
Frame Size	100 mm
Magnet Stack	76.2 mm

---

12. Product Applications

Packaging Machinery

The motor is well suited to packaging machines where rapid indexing, synchronized movement, and repeated acceleration and deceleration are required.

Typical mechanisms can include indexing systems, film handling, cutters, feeders, rotary stations, sealing mechanisms, and positioning axes.

The high-speed 5000 rpm rating allows the motor to support compact transmission arrangements and high-cycle machine operation when the mechanical design is correctly matched to the motor.

---

Material Handling

The motor can be used in automated material handling equipment requiring controlled acceleration and accurate positioning.

Examples include conveyor positioning, transfer mechanisms, indexing units, automated handling modules, and rotary transfer systems.

The low-inertia design is particularly useful when the machine repeatedly changes speed rather than running continuously at a fixed speed.

---

Electronic Assembly Equipment

Electronic assembly machines often require precise movement and short cycle times.

Servo motors from this class can be used for positioning stages, component handling, indexing tables, feeder mechanisms, and other motion axes where repeatable servo positioning is required.

The absolute multi-turn feedback system provides the control system with continuous motor position information.

---

Automated Production Machinery

The motor can also be applied to general industrial automation equipment.

Typical examples include automated assembly machines, inspection systems, indexing machines, machine modules, special-purpose production equipment, and synchronized servo axes.

The 1.8 kW continuous power rating provides a useful capacity range for medium-duty servo axes without moving into the larger physical size of higher-capacity motor families.

---

Printing and Converting Equipment

Printing and converting machinery frequently requires coordinated rotary motion and accurate speed control.

Applications may include web handling, cutting, slitting, feeding, indexing, and other mechanisms where motor speed and position need to be controlled by a servo drive.

The 5000 rpm rating can be useful in applications where the motor must operate at high speed while maintaining closed-loop control.

---

Machine Tools

The motor can also be considered for auxiliary motion functions in machine tools and automated machining equipment.

Potential applications include indexing, tool-related auxiliary mechanisms, positioning axes, feeders, and other controlled rotary movements.

The final suitability depends on the required torque curve, duty cycle, mechanical transmission, load inertia, and environmental conditions.

---

13. Main Advantages

High-Speed Operation

The motor has a rated speed of 5000 rpm, providing a substantial speed range for high-cycle automation equipment.

High-speed operation can reduce the need for large transmission ratios in some machine designs and can help achieve short machine cycle times.

---

Low Rotor Inertia

The low-inertia construction is one of the main characteristics of the MPL family.

A lower rotor inertia can improve acceleration and deceleration response when the motor is appropriately matched to the load.

This is particularly useful for indexing and repetitive positioning applications.

---

High Peak Torque

The motor provides approximately 11.1 Nm peak torque compared with 4.18 Nm continuous torque.

The higher short-duration torque capability gives the servo system additional capacity during acceleration and deceleration events.

---

Compact 100 mm Frame

The 100 mm frame provides a useful balance between motor output and physical machine size.

For machine builders, this can simplify the design of compact servo axes while still providing 1.8 kW continuous power.

---

Absolute Multi-Turn Feedback

The absolute multi-turn encoder provides detailed position feedback to the servo control system.

This is useful for machines requiring accurate positioning and coordinated motion between multiple servo axes.

---

Flexible Connector Orientation

The 180° rotatable right-angle SpeedTEC DIN connector provides flexibility when designing cable routing.

This can be particularly useful where the motor is installed close to machine guards, linear guides, gearboxes, or other mechanical components.

---

Keyless Shaft

The keyless shaft configuration provides an alternative mechanical connection arrangement for machines using suitable clamping-type couplings or hubs.

This can be useful when the machine design requires a smooth shaft interface.

---

No Brake Configuration

The absence of a brake reduces the motor configuration to a drive-only servo motor without an integrated holding brake.

This can be suitable for horizontal axes and applications where a separate holding brake is not required.

It also makes it important to evaluate external load-holding requirements before using the motor on a vertical or gravity-loaded axis.

---

14. Servo Drive Compatibility

The MPL-B330P-MK72AA belongs to the MPL servo motor family and has been specified for use with several servo drive families.

Published technical information identifies compatibility with drive families including:

Servo Drive Family	Typical Role
Kinetix 5500	Modern integrated servo motion applications
Kinetix 6200 / 6500	Modular and coordinated motion systems
Kinetix 6000	Multi-axis motion systems
Kinetix 300	Compact servo applications
Kinetix 350	Compact EtherNet-based motion applications
Kinetix 2000	Multi-axis motion control
Kinetix 7000	High-power motion applications
Ultra 3000	Earlier servo motion systems

Compatibility should always be confirmed against the exact drive catalog number, firmware, feedback interface, motor cable, voltage requirements, and application configuration.

---

15. Recommended Same-Series or Related Models

The following models are representative MPL-family or closely related motor choices. They can be used for comparison when selecting a motor with different torque, power, frame, speed, or inertia characteristics.

Model	Rated Speed	Continuous Torque	Peak Torque	Continuous Power	Rotor Inertia	Approx. Weight	Frame / Size
MPL-B310P	5000 rpm	1.58 Nm	3.61 Nm	0.77 kW	0.000044 kg·m²	2.7 kg	Approx. 63 mm class
MPL-B320P	5000 rpm	3.05 Nm	7.91 Nm	1.5 kW	0.000078 kg·m²	3.7 kg	Approx. 80 mm class
MPL-B330P	5000 rpm	4.18 Nm	11.1 Nm	1.8 kW	0.00012 kg·m²	Approx. 4.6–4.7 kg	100 mm
MPL-B420P	5000 rpm	4.74 Nm	13.5 Nm	1.9 kW	0.00026 kg·m²	4.3 kg	100 mm class
MPL-B430P	5000 rpm	6.55 Nm	19.8 Nm	2.2 kW	0.00038 kg·m²	5.5 kg	Approx. 115 mm class

The MPL-B310P is a smaller and lower-output alternative, suitable where the machine requires less torque and lower motor inertia.

The MPL-B320P provides a middle step in continuous torque and power, making it useful when the B310P is too small but the B330P is not required.

The MPL-B330P represents the same basic motor performance class as the subject model. The exact suffix determines features such as shaft configuration, brake configuration, connector configuration, and feedback options.

The MPL-B420P provides slightly higher continuous and peak torque while maintaining a 5000 rpm rating.

The MPL-B430P moves into a higher torque and power range and can be considered where the B330P capacity is insufficient.

---

16. Five Representative Same-Brand Models

The following are representative models from the same brand and are useful for comparison across different motor sizes and performance ranges.

Model	Motor Type / Series	Rated Speed	Continuous Torque	Peak Torque	Power	Rotor Inertia	Approx. Weight	Dimension Reference
MPL-B310P	MPL Low-Inertia Servo	5000 rpm	1.58 Nm	3.61 Nm	0.77 kW	0.000044 kg·m²	2.7 kg	Approx. 63 mm class
MPL-B320P	MPL Low-Inertia Servo	5000 rpm	3.05 Nm	7.91 Nm	1.5 kW	0.000078 kg·m²	3.7 kg	Approx. 80 mm class
MPL-B420P	MPL Low-Inertia Servo	5000 rpm	4.74 Nm	13.5 Nm	1.9 kW	0.00026 kg·m²	4.3 kg	100 mm class
MPL-B430P	MPL Low-Inertia Servo	5000 rpm	6.55 Nm	19.8 Nm	2.2 kW	0.00038 kg·m²	5.5 kg	Approx. 115 mm class
MPL-B4540F	MPL Servo Motor	3000 rpm	10.2 Nm	27.1 Nm	2.6 kW	0.00052 kg·m²	8.6 kg	Larger-frame class

These models should be regarded as representative comparison products rather than a strict ranking of market popularity.

The MPL-B310P emphasizes compact size and low inertia.

The MPL-B320P provides more torque while retaining the high-speed characteristics of the low-inertia family.

The MPL-B420P increases torque capacity while maintaining 5000 rpm operation.

The MPL-B430P provides a further increase in torque and continuous power.

The MPL-B4540F is intended for a substantially higher torque range and a lower rated speed, making it more suitable for applications where torque capacity is more important than 5000 rpm operation.

---

17. Comparison with MPL-B330P-MJ72AA and Other B330P Configurations

The MPL-B330P family contains several suffix variations.

The core B330P motor characteristics can remain similar while the suffix identifies different mechanical or electrical configuration options.

For the MPL-B330P-MK72AA, the important configuration features are:

Configuration Item	MPL-B330P-MK72AA
Motor Family	MPL-B330P
Voltage	460 V
Rated Speed	5000 rpm
Continuous Torque	4.18 Nm
Peak Torque	11.1 Nm
Power	1.8 kW
Encoder	Absolute multi-turn
Encoder Resolution	1024 Sin/Cos cycles/rev
Brake	No brake
Shaft	Keyless
Connector	SpeedTEC DIN, right-angle
Connector Rotation	180°
Frame	100 mm
Stack	76.2 mm
Weight	Approx. 4.72 kg

This makes the model particularly identifiable as a 100 mm, 76.2 mm stack, 5000 rpm, 1.8 kW, no-brake, keyless-shaft, absolute multi-turn encoder configuration.

---

18. Machine Design Considerations

When installing this motor, the mechanical load should be evaluated before selecting the final servo drive parameters.

The most important factors include load torque, acceleration torque, reflected inertia, operating speed, duty cycle, stopping requirements, mechanical coupling, and ambient temperature.

The motor should not be selected solely from the continuous torque number.

For example, a machine may require only 2 Nm during steady-state operation but require substantially more torque during acceleration. In such a case, the peak torque requirement and acceleration time become important selection criteria.

---

19. Inertia Matching

Servo system performance depends strongly on the relationship between motor inertia and reflected load inertia.

The MPL-B330P-MK72AA has approximately 0.00012 kg·m² rotor inertia.

If the machine uses a gearbox, belt drive, screw mechanism, pulley, or other transmission, the load inertia seen by the motor can be significantly different from the physical inertia measured at the load.

Therefore, the machine designer should calculate the load inertia as reflected through the transmission.

Good inertia matching can improve servo tuning, reduce overshoot, improve settling time, and reduce unnecessary motor heating.

---

20. Vertical-Axis Applications

Because this particular model does not include an integral holding brake, vertical-axis applications require special attention.

A servo motor can generate torque while powered and controlled, but this should not automatically be treated as a mechanical safety holding method.

If the load can fall under gravity when motor power is removed, an appropriately rated external holding mechanism may be required.

The holding mechanism should be selected according to the machine’s safety requirements, load mass, transmission ratio, stopping conditions, and applicable machinery standards.

---

21. Cable and Connector Considerations

The right-angle SpeedTEC DIN connector should be considered during machine layout.

Adequate clearance should be maintained around the connector so that the cable does not experience excessive bending or mechanical stress.

The ability to rotate the connector through approximately 180 degrees can help route cables toward the machine cable tray or drag-chain system.

Cable selection should match the motor, drive, current rating, feedback requirements, cable length, installation environment, and flexing requirements.

---

22. Thermal Considerations

Servo motors generate heat as a normal part of operation.

Motor heating is influenced by continuous torque, RMS current, speed, ambient temperature, installation orientation, surrounding components, duty cycle, and ventilation.

The 1.8 kW rating should therefore be considered together with the actual machine duty cycle.

A motor operating at intermittent high torque may have a different thermal profile from a motor operating continuously near its rated torque.

Proper mounting and sufficient heat dissipation are important when the motor is installed in a compact machine enclosure.

---

23. Maintenance Considerations

The motor is designed for industrial servo applications, but correct maintenance remains important.

The motor mounting bolts should remain properly secured, especially on machines with significant vibration or repeated acceleration and deceleration.

The motor shaft and coupling should be inspected for signs of misalignment, excessive vibration, abnormal noise, or mechanical wear.

The connector should be protected from excessive mechanical stress, contamination, and improper cable routing.

The feedback system should also be checked if the machine develops position errors, following errors, unexpected servo faults, or unstable motion.

---

24. Typical Fault Symptoms and Possible Areas to Check

Symptom	Possible Area to Inspect
Motor does not rotate	Drive enable, motor power circuit, feedback connection
Servo fault during startup	Encoder connection, drive configuration, feedback compatibility
Position error	Encoder feedback, mechanical coupling, tuning, load inertia
Excessive vibration	Mechanical alignment, servo tuning, coupling, load resonance
Motor overheating	Continuous load, duty cycle, ambient temperature, ventilation
Excessive noise	Bearing condition, coupling alignment, mechanical resonance
Unexpected stopping	Drive fault, feedback fault, overload, control command
Poor acceleration	Torque requirement, drive sizing, inertia ratio, tuning
Position drift	Feedback system, mechanical slip, coupling, control configuration
Mechanical movement after power loss	Lack of integral brake and insufficient external holding mechanism

These symptoms should be investigated systematically rather than assuming that the motor itself is defective.

---

25. Suitable Application Profile

The MPL-B330P-MK72AA is particularly suitable for machines requiring a combination of:

• 5000 rpm high-speed operation.
• Approximately 1.8 kW continuous motor output.
• 4.18 Nm continuous torque.
• 11.1 Nm peak torque.
• Low rotor inertia.
• Absolute multi-turn feedback.
• 100 mm metric frame construction.
• Keyless shaft connection.
• No integral holding brake.
• Flexible right-angle connector positioning.
• Closed-loop servo positioning.

A typical machine may use this motor for an axis that must repeatedly accelerate, move to a commanded position, decelerate, stop, and then reverse direction.

---

26. Product Selection Advantages

From a machine engineering perspective, the main advantages of the MPL-B330P-MK72AA are its combination of high speed, moderate power, low rotor inertia, high peak torque, and absolute multi-turn feedback.

The 100 mm frame keeps the motor within a relatively compact mechanical envelope while providing 1.8 kW continuous output.

The 5000 rpm speed rating is useful for high-cycle applications where the motor may operate at high rotational speed.

The absolute multi-turn encoder provides detailed position feedback for closed-loop control.

The keyless shaft provides a different mechanical connection option from keyed-shaft versions, which can be advantageous when using precision clamping couplings.

The absence of an integral brake simplifies the motor configuration for applications where a holding brake is unnecessary.

28. Final Product Description

The MPL-B330P-MK72AA is a 100 mm-frame, low-inertia industrial rotary servo motor designed for high-speed closed-loop motion control.

With a 5000 rpm rated speed, 4.18 Nm continuous torque, 11.1 Nm peak torque, and 1.8 kW continuous power rating, it provides a useful combination of speed and torque for automated machinery.

Its approximately 0.00012 kg·m² rotor inertia supports fast dynamic response, particularly when the driven load is properly matched to the motor.

The absolute multi-turn encoder, 1024 Sin/Cos cycles per revolution, and Hiperface feedback protocol provide the position and speed feedback required for accurate servo control.

The 100 mm metric frame and 76.2 mm magnet stack provide a clearly defined mechanical configuration for machine integration.

The keyless shaft distinguishes this model from keyed-shaft variants, while the absence of an integral brake makes it appropriate for applications where an external holding mechanism is not required.

The right-angle SpeedTEC DIN connector with 180-degree rotation provides additional flexibility during machine installation and cable routing.

Overall, the MPL-B330P-MK72AA is a high-speed, low-inertia servo motor configuration intended for automated machinery requiring precise positioning, repeated acceleration and deceleration, coordinated motion, and reliable closed-loop feedback.

Its strongest technical characteristics are the combination of 5000 rpm speed, 1.8 kW continuous power, 4.18 Nm continuous torque, 11.1 Nm peak torque, low rotor inertia, absolute multi-turn feedback, 100 mm frame size, 76.2 mm stack length, keyless shaft, and no-brake configuration.

For replacement work, the exact suffix MPL-B330P-MK72AA should be matched carefully rather than replacing it solely with another B330P model, because shaft configuration, brake configuration, feedback arrangement, connector arrangement, and other options can differ between suffixes.
