Allen-Bradley MPL-B560F-SK74AA Servo Motor – Detailed Product Description
1. Product Overview
The Allen-Bradley MPL-B560F-SK74AA is a high-performance AC rotary servo motor designed for industrial motion-control applications where accurate positioning, fast response, controlled acceleration, and reliable continuous operation are important.
The motor belongs to the MP-Series MPL family of low-inertia brushless servo motors. It is designed for demanding automated machinery and is particularly suitable for applications that require precise closed-loop motion rather than simple constant-speed rotation.
The MPL-B560F-SK74AA uses a 460 V armature voltage and belongs to the 400 V / 480 V class. It has a 165 mm frame size, a 152.4 mm magnet stack length, and a rated speed of 3000 rpm.
One of the most important characteristics of this model is its combination of a low-inertia motor design, single-turn high-resolution absolute encoder, keyless shaft extension, and integrated 24 V DC holding brake.
This configuration makes the motor well suited to automated machinery where the motor must respond quickly to changing motion commands while maintaining accurate position feedback.
The keyless shaft is also an important distinction from keyed-shaft configurations in the same product family. It allows the motor to be used with mechanical coupling systems designed specifically for a smooth shaft interface.

The 165 mm frame size is one of the most important mechanical selection dimensions.
The 152.4 mm magnet stack length identifies the motor’s active stack configuration and is also useful when comparing this model with other motors in the same family.
For actual machine construction, the frame size and stack length alone are not enough to determine the complete installation envelope. Shaft extension, flange geometry, connector clearance, brake housing, and mounting-hole dimensions should also be considered.
6. Dimensions and Weight
The MPL-B560F-SK74AA has a 165 mm frame size and a 152.4 mm magnet stack.
Its approximate listed product weight is 14.51 kg.
| Dimension / Weight Item | Value |
|---|---|
| Model | MPL-B560F-SK74AA |
| Frame Size | 165 mm |
| Frame Size in Inches | 6.50 in |
| Magnet Stack Length | 152.4 mm |
| Magnet Stack in Inches | 6.0 in |
| Approx. Weight | 14.51 kg |
| Shaft Configuration | Keyless |
| Mounting | IEC metric flange |
| Connector | Right-angle DIN connector |
| Complete Motor Envelope | Depends on mechanical configuration |
The 14.51 kg weight should be considered when designing motor mounting brackets, machine frames, lifting arrangements, and maintenance procedures.
For machines using several motors, the total installed motor mass can also become significant.
When designing the mechanical structure, the motor weight should therefore be considered together with the gearbox, coupling, cables, brake, and driven mechanism.
7. Product Model Number Explanation
The model number MPL-B560F-SK74AA identifies a specific motor configuration within the MPL family.
| Model Code | General Identification |
|---|---|
| MPL | MPL low-inertia brushless servo motor family |
| B | Motor configuration |
| 5 | Frame-size classification |
| 60 | Magnet-stack designation |
| F | Motor configuration designation |
| S | Single-turn feedback configuration |
| K | Keyless shaft configuration |
| 74 | 24 V DC brake configuration |
| AA | Product configuration / revision designation |
The letter K is particularly important because this model uses a keyless shaft.
The S designation is associated with the single-turn high-resolution feedback configuration.
The 74 portion identifies the configuration with a 24 V DC holding brake.
8. Keyless Shaft Design
One of the major differences between the MPL-B560F-SK74AA and keyed-shaft versions is the use of a keyless shaft extension.
A keyless shaft can be advantageous when the machine uses a precision coupling or another clamping-type mechanical connection.
Instead of relying on a traditional shaft key, the mechanical transmission is selected to grip the shaft securely through the appropriate coupling arrangement.
This can provide a clean mechanical interface and is useful in applications where precise coupling alignment is important.
Typical applications include:
- Servo couplings
- Precision gearboxes
- Belt-drive systems
- Rotary tables
- Indexing systems
- Feed mechanisms
- Machine-tool axes
- Automated positioning systems
The coupling should always be selected according to the actual shaft dimensions, torque, speed, radial load, axial load, and required positioning accuracy.
9. Single-Turn High-Resolution Encoder
The MPL-B560F-SK74AA uses a single-turn high-resolution absolute encoder.
The encoder provides the servo drive with information about the motor shaft’s actual position.
This feedback is essential for closed-loop motion control.
The encoder configuration is characterized by:
- Single-turn absolute operation
- High-resolution position feedback
- 1024 Sin/Cos cycles per revolution
- Hiperface communication protocol
The feedback system allows the control system to compare the commanded motor position with the actual motor position.
This is what enables the servo system to correct motion errors and maintain accurate positioning.
10. Benefits of Single-Turn Feedback
Single-turn feedback is particularly useful for machines where accurate angular position within one motor revolution is important.
Typical applications include:
- Rotary indexing
- Positioning tables
- Feed mechanisms
- Packaging axes
- Assembly machines
- Machine-tool axes
- Conveyor synchronization
- Rotary transfer equipment
For applications requiring absolute position information across many motor revolutions, a multi-turn configuration may be more appropriate.
This is why the single-turn and multi-turn versions of the MPL family should be selected according to the actual machine motion requirements.
11. 24 V DC Holding Brake
The MPL-B560F-SK74AA includes a 24 V DC holding brake.
The brake is designed to hold the motor shaft in position when the machine is stopped or when the servo system is not actively producing torque.
This feature is particularly useful for vertical or gravity-loaded axes.
Typical applications include:
- Vertical lifting
- Z-axis mechanisms
- Elevating platforms
- Vertical transfer systems
- Pick-and-place equipment
- Material handling
- Vertical machine axes
The brake is primarily a holding function.
The application should not assume that a holding brake alone provides complete machine safety. If the machine involves personnel protection or a hazardous vertical load, additional safety and mechanical protection should be incorporated into the machine design.
12. SpeedTEC DIN Connector
The motor uses a SpeedTEC DIN connector in a right-angle configuration.
The connector can be rotated through approximately 180 degrees.
This is useful when the motor is installed inside a compact machine where cable access is limited.
The adjustable connector can help with:
- Cable routing
- Machine-space optimization
- Connector accessibility
- Cable bend management
- Servo cabinet organization
- Multi-axis machine installation
A properly planned cable route can reduce mechanical stress on the connector and make maintenance easier.
13. Product Introduction
The MPL-B560F-SK74AA is designed for applications where ordinary motor operation is not enough.
A conventional motor may be used when the main requirement is simply to rotate a load.
A servo motor, by contrast, is intended to provide controlled motion.
The servo system continuously monitors motor feedback and adjusts motor torque and speed according to the commanded motion.
This makes the MPL-B560F-SK74AA appropriate for applications where the machine must know where the motor is, how fast it is moving, and how accurately it is following the commanded motion.
The low-inertia construction further improves dynamic response.
When the machine repeatedly accelerates, stops, reverses, or indexes, a low-inertia motor can respond more quickly than a motor with a significantly higher rotor inertia.
This makes the MPL-B560F-SK74AA a practical choice for automated machinery with demanding motion profiles.
14. Main Product Advantages
14.1 Low-Inertia Design
The low-inertia design is one of the most important advantages of the MPL series.
Lower rotor inertia can allow faster acceleration and deceleration, especially when the motor is correctly matched to the mechanical load.
This can help reduce cycle time in high-speed automation.
14.2 High-Resolution Feedback
The 1024 Sin/Cos encoder provides detailed position information to the servo system.
This supports accurate positioning, speed control, and repeatable motion.
14.3 3000 rpm Rated Speed
The 3000 rpm speed rating makes the motor suitable for many industrial machine axes.
It provides sufficient speed for applications such as feeding, indexing, rotary positioning, and automated material movement.
14.4 Approximately 26.8 N·m Continuous Stall Torque
The motor provides a substantial continuous stall torque capability for its frame class.
This makes it suitable for applications with significant acceleration requirements and relatively demanding mechanical loads.
Actual operating torque depends on speed, temperature, duty cycle, drive configuration, and mechanical load.
14.5 Integrated 24 V DC Brake
The integrated holding brake is a major advantage for vertical and gravity-loaded mechanisms.
It provides a convenient method of holding the shaft when motor torque is not being actively applied.
14.6 Keyless Shaft
The keyless shaft provides compatibility with appropriate precision coupling systems.
This can be useful where the mechanical designer prefers a clamping-style shaft connection.
14.7 Rotatable Right-Angle Connector
The right-angle connector can simplify installation in compact machinery.
The approximately 180-degree rotational adjustment gives additional freedom when routing motor cables.
14.8 IEC Metric Mounting
The IEC metric mounting arrangement is useful for industrial machine construction using metric mechanical standards.
This can simplify mechanical integration into equipment designed around metric dimensions.
15. Main Applications

16. Typical Machine System
A servo motor normally works as part of a complete motion-control system.
| System Component | Function |
|---|---|
| MPL-B560F-SK74AA | Provides controlled rotary mechanical motion |
| Servo Drive | Supplies controlled current and voltage to the motor |
| Motion Controller | Generates movement commands |
| Encoder | Provides position feedback |
| Brake Circuit | Controls the 24 V DC holding brake |
| Coupling | Connects the motor to the mechanical load |
| Gearbox | Changes speed and torque when required |
| Machine Controller | Coordinates machine operation |
| Safety System | Handles machine safety functions |
The motor should not be selected independently from the drive.
Motor voltage, current, feedback type, brake configuration, speed, torque, inertia, and cable requirements should all be compatible with the complete servo system.
17. Mechanical Installation
The MPL-B560F-SK74AA uses IEC metric flange mounting with free mounting holes.
During installation, the motor flange should be correctly aligned with the machine.
The motor should not be forced into position through the shaft or coupling.
Correct alignment is important because excessive mechanical misalignment can increase bearing loads and reduce service life.
The keyless shaft also requires an appropriate coupling.
The coupling must be capable of transmitting the required torque at the required speed while maintaining proper alignment.
18. Thermal Considerations
Servo motors can generate substantial heat during high-load operation.
Motor temperature depends on several factors:
- Continuous torque
- Peak torque
- Operating speed
- Acceleration frequency
- Duty cycle
- Ambient temperature
- Installation orientation
- Mechanical load
- Cooling conditions
The machine designer should provide adequate clearance around the motor and avoid unnecessary heat accumulation.
A motor that operates continuously close to its maximum thermal capability may require additional attention to cooling and duty-cycle management.
19. Brake Application Considerations
The 24 V DC brake is particularly valuable in vertical applications.
However, the brake should be treated as part of the overall machine design.
The control sequence should ensure that the brake is not repeatedly used as a dynamic stopping device unless the application has specifically been designed for that type of operation.
For a vertical axis, the machine designer should consider:
- What happens when servo power is removed.
- Whether the mechanical load can move under gravity.
- How quickly the brake engages.
- Whether an additional mechanical holding device is required.
- Whether the application requires a separate safety-rated stopping function.
20. Five Recommended Same-Series or Related Models
The following models are useful alternatives or comparison points within the MPL family.
| Model | Series | Feedback | Speed | Brake | Shaft | Frame / Stack | Approx. Weight |
|---|---|---|---|---|---|---|---|
| MPL-B560F-SJ74AA | MPL low-inertia servo | Single-turn high-resolution | 3000 rpm | 24 V DC | Keyed | 165 mm / 152.4 mm | Approx. 14.5 kg class |
| MPL-B560F-SK74AA | MPL low-inertia servo | Single-turn high-resolution | 3000 rpm | 24 V DC | Keyless | 165 mm / 152.4 mm | Approx. 14.51 kg |
| MPL-B560F-SJ72AA | MPL low-inertia servo | Single-turn high-resolution | 3000 rpm | No brake configuration | Keyed | 165 mm / 152.4 mm | Approx. 14.5 kg class |
| MPL-B560F-MK74AA | MPL low-inertia servo | Multi-turn high-resolution | 3000 rpm class | 24 V DC | Keyless configuration | 165 mm / 152.4 mm class | Configuration dependent |
| MPL-B580F-SK74AA | MPL low-inertia servo | Single-turn high-resolution | 3000 rpm | 24 V DC | Keyless | 165 mm / 203.2 mm | Configuration dependent |
Among these models, the MPL-B560F-SJ74AA is one of the closest comparisons because it has a similar frame and stack configuration while using a keyed shaft.
The MPL-B560F-SK74AA is the better choice when the application specifically requires a keyless shaft arrangement.
The MPL-B560F-MK74AA is more appropriate when multi-turn feedback is preferred.
The MPL-B580F-SK74AA uses a longer magnet stack and can therefore be considered when a higher torque-capability configuration within the same general frame family is required.
21. Comparison of Recommended Models
| Model | Main Feature | Feedback | Shaft | Brake | Frame | Stack |
|---|---|---|---|---|---|---|
| MPL-B560F-SJ74AA | Single-turn, keyed shaft | Single-turn | Keyed | 24 V DC | 165 mm | 152.4 mm |
| MPL-B560F-SK74AA | Single-turn, keyless shaft | Single-turn | Keyless | 24 V DC | 165 mm | 152.4 mm |

22. Five Popular Models from the Same Brand
The following products represent useful products to consider when building or expanding a broader industrial automation and motion-control system.
| Model | Product Type | Main Function | Typical Application | Key Parameter | Dimensions | Weight |
|---|---|---|---|---|---|---|
| MPL-B560F-SK74AA | Servo Motor | Precision rotary motion | Packaging, material handling, machine axes | 3000 rpm, 26.8 N·m class | 165 mm frame / 152.4 mm stack | 14.51 kg |
| MPL-B560F-SJ74AA | Servo Motor | Closed-loop rotary motion | Positioning and indexing | 3000 rpm, single-turn feedback | 165 mm frame / 152.4 mm stack | Approx. 14.5 kg class |

| 2198-H025-ERS | Servo Drive | Servo motor control | Motion-control systems | High-performance servo drive | Drive-specific | Configuration dependent |
| 1756-L81E | Programmable Controller | Machine control | Industrial automation | Programmable controller | Controller-specific | Configuration dependent |
The first three models are direct motion-product comparisons.
The servo drive and programmable controller are not replacement motors. They are included because they are important components in a complete industrial motion-control architecture.
23. MPL-B560F-SK74AA vs. MPL-B560F-SJ74AA
The two models are closely related but differ in the shaft configuration.
| Parameter | MPL-B560F-SK74AA | MPL-B560F-SJ74AA |
|---|---|---|
| Product Series | MPL | MPL |
| Frame Size | 165 mm | 165 mm |
| Magnet Stack | 152.4 mm | 152.4 mm |
| Rated Speed | 3000 rpm | 3000 rpm |
| Feedback | Single-turn high-resolution | Single-turn high-resolution |
| Brake | 24 V DC | 24 V DC |
| Shaft | Keyless | Keyed |
| Connector | Right-angle DIN | Right-angle DIN |
| Mounting | IEC metric | IEC metric |
| Continuous Stall Torque | Approx. 26.8 N·m | Approx. 26.8 N·m |
| Approx. Weight | 14.51 kg | Approx. 14.5 kg class |
| Best Selection Reason | Keyless coupling arrangement | Keyed coupling arrangement |
The main selection decision between these two models is therefore the mechanical shaft interface.
If the machine is already designed around a keyed coupling, the SJ configuration may be the more convenient choice.
If the mechanical design uses a keyless coupling or clamping connection, the SK configuration is more suitable.
24. MPL-B560F-SK74AA vs. Multi-Turn Models
A single-turn model and a multi-turn model should not be treated as identical products.
The main difference is the way the encoder handles position information.
A single-turn encoder provides highly accurate position information within one motor revolution.
A multi-turn encoder is designed for applications where position information across multiple revolutions is important.
| Selection Factor | MPL-B560F-SK74AA | Multi-Turn MPL Configuration |
|---|---|---|
| Feedback | Single-turn | Multi-turn |
| Position Reference | Within one revolution | Across multiple revolutions |
| Typical Application | Indexing, positioning, rotary motion | Long-travel or multi-revolution positioning |
| Brake | 24 V DC | Configuration dependent |
| Shaft | Keyless | Configuration dependent |
| Frame | 165 mm | Depends on model |
| Stack | 152.4 mm | Depends on model |
The correct choice depends on the machine’s position-control requirements.
25. Applications Where the Motor Has a Strong Advantage
The MPL-B560F-SK74AA is particularly attractive for machines with frequent movement.
For example, a packaging machine may move a product forward, stop, reposition, reverse, and repeat the same operation thousands of times.
A servo motor must handle these changing commands smoothly.
The low-inertia construction helps the motor respond rapidly, while the encoder provides continuous position feedback.
This combination makes the motor well suited to high-cycle automation.
26. High-Speed Positioning Applications
The 3000 rpm rated speed makes the motor suitable for applications where the machine needs relatively fast rotary movement.
Potential applications include:
- Rotary indexing
- High-speed feeding
- Automated positioning
- Conveyor synchronization
- Cutting
- Packaging
- Printing
- Assembly
The final achievable machine speed depends on the mechanical transmission, load inertia, acceleration profile, servo drive, and machine controller.
27. Advantages in Packaging Equipment
Packaging machinery often places several demands on a motor at the same time.
The motor may need to:
- Start rapidly
- Stop precisely
- Repeat the same position
- Synchronize with another axis
- Maintain speed
- Reverse direction
- Operate for long periods
The MPL-B560F-SK74AA addresses these requirements through its low-inertia construction, high-resolution feedback, 3000 rpm speed capability, and substantial torque capability.
The 24 V DC holding brake also provides additional flexibility for machine axes where shaft holding is required.
28. Advantages in Material Handling
Material-handling systems often contain conveyors, lifts, positioning axes, and transfer mechanisms.
The motor’s servo feedback allows these movements to be controlled more precisely than a simple open-loop motor.
The holding brake is particularly useful when the axis has a vertical component.
The keyless shaft can also be convenient when the mechanical system uses a precision coupling.
29. Advantages in Automated Assembly
Automated assembly equipment depends heavily on repeatability.
A component may need to be moved into exactly the same position hundreds or thousands of times.
The servo system can continuously monitor the motor position and adjust the output accordingly.
This makes the MPL-B560F-SK74AA suitable for:
- Component positioning
- Transfer systems
- Rotary indexing
- Pick-and-place mechanisms
- Assembly stations
- Automated feeders
30. Maintenance Considerations
Although the motor is designed for industrial use, proper maintenance is still important.
Regular inspection should include:
- Motor mounting
- Coupling alignment
- Shaft condition
- Connector condition
- Cable condition
- Brake operation
- Motor temperature
- Abnormal vibration
- Abnormal noise
- Positioning accuracy
- Mechanical backlash
The motor should also be kept within its intended operating conditions.
A sudden increase in vibration, temperature, noise, or positioning error may indicate a mechanical, electrical, feedback, or load-related problem.
31. Common Installation Mistakes
Incorrect Coupling Selection
Because this model has a keyless shaft, the coupling must be designed for the appropriate shaft interface.
Using an unsuitable coupling can cause slipping, vibration, or excessive shaft loading.
Poor Shaft Alignment
Misalignment can increase bearing loads and may shorten motor life.
The motor and driven machine should be aligned carefully.
Excessive Radial or Axial Load
The mechanical load applied to the shaft should remain within the motor’s allowable limits.
Incorrect Brake Sequence
The holding brake should be controlled in coordination with the servo system.
Insufficient Cable Clearance
The connector area should have enough room for proper cable routing and maintenance access.
Poor Thermal Management
The motor should have adequate space for heat dissipation.
Continuous operation under heavy load can increase motor temperature.

The MPL-B560F-SK74AA is a powerful and versatile industrial servo motor for applications that require accurate closed-loop rotary motion.
Its 165 mm frame and 152.4 mm magnet stack place it in a substantial motor size category within the MPL family.
The 3000 rpm rated speed makes it suitable for a wide range of automated machine axes, while the approximately 26.8 N·m continuous stall torque provides substantial torque capability for demanding motion applications.
The single-turn high-resolution encoder provides accurate position feedback and supports closed-loop servo operation.
The keyless shaft is one of the most distinctive mechanical characteristics of this particular model.
It makes the motor a good candidate for applications using precision clamping couplings or other keyless transmission arrangements.
The integrated 24 V DC holding brake is another important advantage, particularly for vertical axes and other applications where the motor shaft must remain stationary when active servo torque is removed.
The right-angle, rotatable connector provides additional flexibility during machine installation and cable routing.
Overall, the MPL-B560F-SK74AA is best suited to industrial machinery where accurate positioning, rapid response, reliable feedback, controlled speed, and mechanical holding are all important.
It can be considered for packaging machinery, automated assembly, material handling, machine tools, printing and converting equipment, indexing systems, positioning mechanisms, and other automated production machinery.
