MPL-B4540F-HK72AA Low-Inertia Servo Motor

1. Product Overview

The MPL-B4540F-HK72AA is a low-inertia brushless rotary servo motor designed for industrial motion-control and automated machinery applications.

It belongs to the MPL Low-Inertia Servo Motor Series within the broader MP-Series product family.

The motor uses a 130 mm metric frame and a 101.6 mm magnet stack, placing it in a relatively high-torque configuration within the compact MPL motor range.

The motor is rated for approximately 3000 rpm, with approximately 10.2 N·m continuous torque and 27.1 N·m peak torque.

The H K configuration is intended for applications requiring a higher-resolution feedback arrangement together with a keyless shaft.

The 72AA configuration is a no-brake version, so there is no integral 24 V DC holding brake in this particular model.

This combination makes the MPL-B4540F-HK72AA especially suitable for machines where accurate feedback and rapid servo response are important, but where an integral motor holding brake is not required.

The motor also uses a right-angle SpeedTEC DIN connector, which is useful when the motor is installed in a machine with restricted cable-routing space.

The overall design is aimed at applications requiring repeatable positioning, controlled acceleration and deceleration, coordinated motion, and stable closed-loop speed control.

---

4. Dimensions and Weight

The MPL-B4540F-HK72AA uses a 130 mm metric frame with a 101.6 mm magnet stack.

The 130 mm frame is the primary mechanical mounting dimension used when integrating the motor into a machine.

The 101.6 mm magnet stack indicates the longer motor stack used in the B4540F configuration.

Mechanical Parameter	Specification
Model	MPL-B4540F-HK72AA
Frame Size	130 mm
Frame Designation	Frame 45
Magnet Stack Length	101.6 mm
Flange Type	Metric flange
Mounting Frame	130 mm class
Shaft	Keyless
Shaft Seal	None
Connector	Right-angle SpeedTEC DIN
Connector Rotation	180°
Brake	No integral brake
Approx. Motor Weight	8.6 kg

The approximate motor weight is 8.6 kg.

This value is useful when calculating machine-frame loads, robotic-axis mass, moving-axis inertia, mounting requirements, and transportation weight.

The actual overall installation envelope should not be calculated from the frame size alone.

The shaft projection, connector position, cable bend radius, mounting flange, and any coupling attached to the motor shaft must also be considered.

For a machine with very limited installation space, the connector direction is especially important.

---

5. Motor Performance

The MPL-B4540F-HK72AA is a 3000 rpm servo motor with approximately 10.2 N·m continuous torque and 27.1 N·m peak torque.

This makes it suitable for medium-duty servo axes requiring a relatively high torque level without moving to a much larger motor frame.

Performance Parameter	Value
Model	MPL-B4540F-HK72AA
Rated Speed	3000 rpm
Maximum Speed	3000 rpm
Continuous Torque	10.2 N·m
Peak Torque	27.1 N·m
Rated Output	Approx. 2.6 kW
Rotor Inertia	Approx. 0.00052 kg·m²
Frame Size	130 mm
Stack Length	101.6 mm
Approx. Weight	8.6 kg

The continuous torque rating is important when the motor has to carry a sustained mechanical load.

The peak torque rating is more relevant during acceleration, deceleration, indexing, transient loads, and rapid changes in machine speed.

---

6. Low-Inertia Servo Construction

Low inertia is one of the key characteristics of the MPL motor family.

The rotor is designed to respond quickly to changes in commanded speed.

In a machine that repeatedly accelerates and decelerates, a lower rotor inertia can help the servo system achieve the desired motion more quickly.

This is particularly useful for:

• Indexing systems
• Packaging machines
• Assembly equipment
• Pick-and-place systems
• Printing machinery
• Labeling machinery
• Material-handling equipment
• Rotary positioning systems
• Automated production machinery

The motor is therefore better suited to dynamic motion than a conventional motor intended primarily for constant-speed operation.

---

7. High-Resolution Feedback

One of the main characteristics of the HK72AA configuration is its high-resolution feedback arrangement.

High-resolution feedback allows the servo controller to obtain more detailed information about motor position and movement.

This can be valuable when the application requires:

• Accurate positioning
• Smooth low-speed operation
• Precise indexing
• Fine motion control
• Coordinated multi-axis movement
• Repeatable acceleration and deceleration
• High-quality synchronization

The feedback system works together with the servo drive.

The controller issues a motion command, the drive supplies controlled current to the motor, and the feedback device reports the motor’s actual motion.

The control system then continuously corrects the motor command according to the difference between commanded and actual movement.

---

8. Keyless Shaft Configuration

The MPL-B4540F-HK72AA uses a keyless shaft.

This is an important difference from models such as the HJ72AA, which use a keyed shaft.

A keyless shaft is commonly used with specially designed clamping couplings or other shaft-locking arrangements.

The connection relies on the clamping mechanism rather than a traditional shaft key.

This can provide a very concentric mechanical connection when the correct coupling is used.

Keyless shaft arrangements can be useful in precision motion systems where accurate alignment and low mechanical play are important.

Typical applications include:

• Precision couplings
• Servo gearboxes
• Ball-screw drives
• Rotary positioning mechanisms
• Direct mechanical couplings
• Precision indexing systems
• High-response machine axes

The coupling must be selected specifically for the motor shaft diameter, torque, speed, and required allowable misalignment.

---

9. No Integral Brake

The MPL-B4540F-HK72AA is a no-brake configuration.

There is no integral 24 V DC holding brake on this motor.

This makes the model suitable for applications where the machine does not require a motor-mounted holding brake.

It can also be useful where another mechanical braking or locking mechanism is already installed.

The absence of a brake can simplify the motor-side configuration and eliminates the need for brake wiring at the motor.

However, this characteristic should be considered carefully for vertical axes.

If a vertical load can move under gravity when servo torque is removed, the machine may require a brake-equipped motor or an independent mechanical holding device.

---

10. SpeedTEC DIN Right-Angle Connector

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

The right-angle connector helps reduce the amount of space required for cable routing directly behind the motor.

This can be useful in compact machinery where a straight connector would interfere with the machine frame or adjacent components.

The connector arrangement also allows rotational positioning.

This gives the installer more flexibility when routing the servo cable.

Typical benefits include:

• Reduced cable-routing space
• Easier installation in compact machines
• Better compatibility with cable tracks
• Flexible cable exit direction
• Easier access during maintenance

---

11. Product Introduction

The MPL-B4540F-HK72AA is designed for servo applications where dynamic response and accurate feedback are more important than simple constant-speed operation.

A servo system normally consists of several coordinated elements.

The controller generates the motion command.

The servo drive controls the electrical power supplied to the motor.

The motor converts electrical energy into mechanical torque.

The encoder provides feedback.

The control system uses this feedback to maintain the required speed and position.

This arrangement allows the motor to perform controlled acceleration, deceleration, positioning, synchronization, and speed regulation.

The MPL-B4540F-HK72AA is particularly useful where machine motion needs to be repeatable from one production cycle to the next.

---

12. Main Product Advantages

12.1 High-Resolution Feedback

The high-resolution feedback configuration is one of the main reasons to choose the HK72AA model.

It provides detailed motor-position information for the servo control system.

This is especially useful for precise positioning and coordinated motion.

---

12.2 Low-Inertia Rotor

The low-inertia design allows fast changes in motor speed.

This is beneficial in high-cycle machinery.

The motor can respond quickly to acceleration and deceleration commands when the complete servo system is correctly tuned.

---

12.3 Strong Torque Capability

The 10.2 N·m continuous torque rating provides useful continuous load capacity.

The 27.1 N·m peak torque rating provides additional capacity for acceleration and transient load conditions.

---

12.4 3000 rpm Operating Speed

The 3000 rpm speed rating provides a useful balance between torque and speed.

It is suitable for many rotary and transmission-driven machine axes.

---

12.5 Keyless Shaft

The keyless shaft can provide a precise mechanical interface when used with a suitable clamping coupling.

This can be particularly useful in precision motion systems.

---

12.6 Compact 130 mm Frame

The 130 mm frame allows the motor to provide relatively high torque while maintaining a manageable industrial mounting envelope.

---

12.7 101.6 mm Magnet Stack

The longer magnet stack gives the B4540F configuration its higher torque capability compared with shorter-stack MPL motors.

---

12.8 Right-Angle Connector

The right-angle connector makes the motor easier to install in machines with limited cable space.

---

12.9 No-Brake Configuration

Where a brake is not required, the no-brake configuration provides a simpler motor arrangement.

It avoids unnecessary brake wiring and allows the motor to be selected specifically for non-brake applications.

---

13. Typical Applications

Packaging Machinery

Packaging equipment often requires fast, repeatable motion.

The MPL-B4540F-HK72AA can be used for product feeding, indexing, positioning, cutting, rotary mechanisms, and synchronized motion.

The low-inertia design is useful for repeated acceleration and deceleration.

---

Automated Assembly Equipment

Automated assembly systems often require accurate positioning.

The motor can control rotary positioning mechanisms, transfer systems, assembly stations, and other servo-driven axes.

The high-resolution feedback configuration can be useful where precise positioning is required.

---

Rotary Indexing Systems

Rotary indexing machines require the motor to move quickly to a defined position and then stop accurately.

The combination of low inertia, high-resolution feedback, and peak torque makes this motor suitable for such applications.

---

Material Handling

Servo-controlled material-handling equipment can use the motor for controlled movement, synchronization, and positioning.

Applications include:

• Transfer mechanisms
• Feed systems
• Indexing conveyors
• Sorting equipment
• Product positioning
• Automated handling systems

---

Printing Machinery

Printing equipment often requires synchronized movement between rollers, feeders, and other rotating components.

The feedback system allows the motor to operate as part of a coordinated motion system.

---

Labeling Machinery

Labeling systems require accurate timing between product movement and label application.

A servo motor can control the relevant feed and positioning mechanisms with repeatable motion.

---

Machine Tools

The motor can be considered for suitable auxiliary positioning and rotary axes.

The exact suitability depends on machine load, speed, torque, inertia, and required positioning performance.

---

Textile Equipment

Textile machinery often includes feeding, winding, tension-control, and positioning systems.

Servo control allows these mechanisms to operate with controlled speed and coordinated motion.

---

15. Five Same-Series or Closely Related Models

The following models are useful comparisons for the MPL-B4540F-HK72AA.

Model	Speed	Continuous Torque	Peak Torque	Feedback	Shaft	Brake	Stack	Frame	Approx. Weight
MPL-B4540F-HK72AA	3000 rpm	10.2 N·m	27.1 N·m	High-resolution	Keyless	No	101.6 mm	130 mm	8.6 kg
MPL-B4540F-HK74AA	3000 rpm	10.2 N·m	27.1 N·m	High-resolution	Keyless	24 V DC	101.6 mm	130 mm	8.6 kg
MPL-B4540F-HJ72AA	3000 rpm	10.2 N·m	27.1 N·m	Incremental	Keyed	No	101.6 mm	130 mm	8.6 kg
MPL-B4540F-HJ74AA	3000 rpm	10.2 N·m	27.1 N·m	Incremental	Keyed	24 V DC	101.6 mm	130 mm	8.6 kg
MPL-B4530K-HK72AA	4000 rpm	8.25 N·m	20.3 N·m	High-resolution	Keyless	No	76.2 mm	130 mm	Approx. 7–8 kg class

The first four models are particularly useful because they are based on the same B4540F motor platform.

The HJ models use a keyed shaft, while the HK models use a keyless shaft.

The 72AA configuration is the no-brake version, while the 74AA configuration includes a 24 V DC brake.

This makes these four models convenient for comparing feedback, shaft, and brake requirements without changing the basic motor size.

---

16. Detailed Comparison of Related Models

MPL-B4540F-HJ72AA

The HJ72AA is the most straightforward comparison with the HK72AA.

Both are no-brake B4540F motors.

The major difference is the feedback configuration and shaft arrangement.

The HJ72AA uses an incremental feedback configuration and keyed shaft, while the HK72AA uses the higher-resolution feedback configuration and keyless shaft.

The HJ72AA is therefore more suitable when a keyed mechanical connection is preferred.

---

MPL-B4540F-HJ74AA

The HJ74AA combines the incremental feedback configuration with a keyed shaft and 24 V DC brake.

It is a practical option when the application requires a motor-mounted holding brake.

---

MPL-B4540F-HK74AA

The HK74AA is one of the closest alternatives to the HK72AA.

The basic motor performance and mechanical platform are similar, but the HK74AA adds the 24 V DC holding brake.

For applications requiring high-resolution feedback and a holding brake, the HK74AA is the more appropriate configuration.

---

MPL-B4530K-HK72AA

The B4530K-HK72AA moves to a shorter magnet stack and a higher 4000 rpm speed class.

It provides approximately 8.25 N·m continuous torque and 20.3 N·m peak torque.

It is therefore a useful alternative when higher speed is more important than the additional torque provided by the B4540F motor.

---

17. Five Same-Brand Popular or Widely Used Models

The following models provide a broader comparison within the same brand’s servo-motor range.

They should not all be treated as direct replacements.

They represent different combinations of speed, torque, frame size, feedback, shaft configuration, and brake capability.

Model	Product Type	Rated Speed	Continuous Torque	Peak Torque	Feedback	Brake	Dimensions	Approx. Weight
MPL-B4530K-HK72AA	Servo Motor	4000 rpm	8.25 N·m	20.3 N·m	High-resolution	No	130 mm frame × 76.2 mm stack	Approx. 7–8 kg
MPL-B4540F-HK74AA	Servo Motor	3000 rpm	10.2 N·m	27.1 N·m	High-resolution	24 V DC	130 mm frame × 101.6 mm stack	8.6 kg
MPL-B4560F-MJ74AA	Servo Motor	3000 rpm	14.1 N·m	34.4 N·m	Multi-turn absolute	24 V DC	130 mm frame × 152.4 mm stack	11.82 kg
MPL-B520K-MJ74AA	Servo Motor	Up to 4000 rpm	Approx. 10.7 N·m	Approx. 23.2 N·m	Multi-turn absolute	24 V DC	Larger frame class	Approx. 9.8 kg
MPL-B540K-MJ74AA	Servo Motor	4000 rpm	19.4 N·m	48.6 N·m	Multi-turn absolute	24 V DC	165 mm frame × 101.6 mm stack class	Approx. 15.0 kg

The B4530K is attractive when higher speed is required.

The B4540F is a balanced option for 3000 rpm applications.

The B4560F provides greater torque while remaining within the general MPL low-inertia family.

The B520K and B540K move into larger motor classes and can be considered when the required torque exceeds the B4540F/B4560F range.

---

18. Model Selection by Application Requirement

Application Requirement	Suitable Model
3000 rpm, high-resolution feedback, no brake	MPL-B4540F-HK72AA
3000 rpm, high-resolution feedback, brake	MPL-B4540F-HK74AA
3000 rpm, incremental feedback, keyed shaft	MPL-B4540F-HJ72AA
3000 rpm, incremental feedback, keyed shaft and brake	MPL-B4540F-HJ74AA
4000 rpm, high-resolution feedback	MPL-B4530K-HK72AA
Higher torque at 3000 rpm	MPL-B4560F series
Higher torque and larger frame	MPL-B540K series
Multi-turn absolute positioning	MPL-B4560F-MJ74AA or related M-series
Vertical axis requiring holding	Brake-equipped configuration
Precision rotary positioning	HK-series configuration

---

19. Why Choose the HK72AA Configuration?

The HK72AA configuration makes sense when the machine requires a combination of high-resolution feedback and a keyless mechanical shaft.

The keyless shaft can be attractive in precision mechanical assemblies where the coupling itself provides the shaft clamping function.

The high-resolution feedback provides the control system with detailed motion information.

The absence of a brake keeps the motor configuration relatively simple when mechanical holding is not required.

This combination can be particularly attractive for horizontal positioning axes.

---

20. Benefits for Precision Motion

Precision motion is not determined by the motor alone.

The mechanical structure, coupling, bearings, transmission, servo drive, encoder feedback, control software, and machine tuning all affect final positioning performance.

However, the MPL-B4540F-HK72AA provides a strong foundation for precision servo motion because it combines low rotor inertia with high-resolution feedback.

The keyless shaft can also be useful where mechanical concentricity and coupling accuracy are important.

---

21. Benefits for High-Cycle Machinery

High-cycle machinery places significant demands on a servo motor.

The motor may accelerate and decelerate thousands of times during a production shift.

The low-inertia design helps reduce the motor’s own rotational resistance to changes in speed.

The peak torque capability provides additional capacity during rapid movement.

The high-resolution feedback allows the servo system to monitor motor position accurately throughout the cycle.

This combination makes the motor well suited to repetitive industrial automation.

---

22. Mechanical Installation

The motor should be mounted to a rigid machine structure.

The mounting flange should be correctly aligned.

The shaft coupling should be selected according to the required torque and speed.

For a keyless shaft, the coupling must be tightened according to the coupling manufacturer’s requirements.

The clamping connection should be clean and correctly aligned.

Any contamination between the shaft and coupling can reduce the reliability of the mechanical connection.

The motor should not be used to support loads beyond its allowable shaft-loading capability.

---

23. Cable Installation

The servo cable should be routed so that it is protected from excessive bending and mechanical damage.

Cable tracks should provide the required bend radius.

The connector should not be subjected to continuous pulling or twisting forces.

Because the motor uses a right-angle connector, the connector orientation should be selected before final cable routing.

This can prevent unnecessary cable loops and reduce mechanical stress on the connector.

---

24. Maintenance

Routine inspection should focus on both the motor and the machine mechanics.

Recommended inspection points include:

• Motor mounting
• Shaft coupling
• Keyless clamping connection
• Bearings
• Motor temperature
• Connector condition
• Power cable
• Feedback cable
• Cable routing
• Mechanical vibration
• Servo fault history
• Abnormal noise
• Load alignment

A sudden increase in vibration or temperature should be investigated before continued operation.

Mechanical misalignment can sometimes appear as an electrical or servo-control problem.

---

25. Environmental Considerations

The motor is intended for industrial motion-control applications.

The installation environment should nevertheless be evaluated carefully.

Factors such as temperature, humidity, dust, oil, vibration, shock, and chemical exposure can affect long-term motor performance.

The model does not use a shaft seal, so applications involving significant contamination around the shaft area require additional consideration.

If the machine is exposed to washdown, coolant, dust, or aggressive chemicals, the environmental requirements should be checked before final motor selection.

---

26. Servo Drive Considerations

The MPL-B4540F-HK72AA must be paired with a compatible servo drive.

The drive must support the motor’s voltage class, feedback arrangement, current requirements, and control method.

The drive should also be correctly sized for both continuous and peak motor requirements.

A drive that is too small may limit the available motor torque.

A drive that is incorrectly configured for the feedback system can result in feedback faults or unstable operation.

The complete servo package should therefore be considered as one system rather than treating the motor as an independent component.

30. Final Product Assessment

The MPL-B4540F-HK72AA is a strong choice for industrial servo applications that require fast dynamic response, relatively high torque, high-resolution feedback, and a precision-oriented mechanical shaft connection.

Its 130 mm frame and 101.6 mm magnet stack give it a useful balance between physical size and torque capability.

The approximately 10.2 N·m continuous torque rating makes it suitable for medium-duty servo axes, while the approximately 27.1 N·m peak torque rating provides additional capacity during acceleration and transient load conditions.

The 3000 rpm operating speed is appropriate for many industrial rotary applications.

The high-resolution feedback configuration is useful where accurate position information and repeatable motion are important.

The keyless shaft is another important feature. When combined with an appropriate clamping coupling, it can provide a precise mechanical connection for servo applications.

The motor does not include an integral brake.

That makes the HK72AA particularly suitable for horizontal axes and other applications where a motor-mounted holding brake is not required.

For vertical or gravity-loaded applications, a brake-equipped configuration or separate mechanical holding system should be considered.

The right-angle SpeedTEC DIN connector is also useful in compact machines because it gives the machine builder more flexibility when routing cables around the motor.

Overall, the MPL-B4540F-HK72AA can be described as a 130 mm-frame, 101.6 mm-stack, 3000 rpm low-inertia servo motor with approximately 10.2 N·m continuous torque, 27.1 N·m peak torque, high-resolution feedback, keyless shaft, no integral brake, and a right-angle industrial servo connector.

It is particularly well suited to precision positioning, packaging, indexing, assembly, material handling, printing, labeling, and other high-cycle industrial automation applications where rapid servo response and detailed feedback are important.
