Siemens 1FK7063-5AF71-1SH0 Servo Motor: Product Overview, Technical Specifications, Applications, Advantages, and Related Models

1. Product Overview

The 1FK7063-5AF71-1SH0 is a model designation associated with the SIMOTICS S-1FK7 family of compact synchronous servo motors. This motor family is designed for industrial automation systems that require controlled rotational movement, repeatable positioning, and coordinated operation with a compatible servo drive.

Servo motors are commonly used in production machinery because they can regulate motor movement through a feedback-based control system. Depending on the machine design, they may be used to drive positioning axes, feed mechanisms, rotary tables, conveyors, and other automated components.

The complete model number is important when selecting or replacing a motor. Different variants within the same family may have different feedback systems, shaft configurations, holding brakes, connectors, protection ratings, and electrical characteristics. A similar model number does not guarantee identical mechanical dimensions or electrical compatibility.

Model-specific note: The exact technical configuration of the 1FK7063-5AF71-1SH0 should be confirmed against its nameplate and matching technical drawing. The information below describes the product family and its likely selection considerations, while unverified dimensions and model-specific values are clearly identified rather than presented as guaranteed specifications.

2. Brand and Product Series

The SIMOTICS S-1FK7 family is intended for applications that require compact motor construction and controlled motion. Motors within this family can be selected for different operating speeds, torque requirements, feedback interfaces, and mechanical installation conditions.

The 1FK7063 designation identifies the motor family and frame-size class, while the remaining characters specify the particular configuration. Those suffixes matter when choosing a replacement because feedback type, shaft design, brake arrangement, and connector configuration can affect whether a motor works with an existing machine.

For this reason, the 1FK7063-5AF71-1SH0 should be evaluated as a complete ordering code rather than selected solely by its series name or frame size.

3. Detailed Technical Parameters

The following specifications describe the principal operating characteristics of the 1FK7063-5AF71-1SH0. The motor uses a multipole resolver, a plain shaft, and an integrated holding brake.

3.1 Rated power and speed

The motor’s rated operating point is approximately 2.29 kW at 3,000 rpm. This makes it a potential choice for industrial machinery requiring controlled rotation at moderate-to-high speed.

The maximum permissible mechanical speed and inverter speed are separate limits. The mechanical limit relates to the motor’s permissible rotational speed, while the inverter limit applies to operation under the relevant drive conditions. Neither maximum value should be treated as the normal continuous operating speed without checking the application requirements.

3.2 Rated torque and maximum torque

The motor has a rated torque of approximately 7.3 Nm at a 100 K temperature rise, a static torque of approximately 11 Nm under the same temperature-rise condition, and a listed maximum torque of 35 Nm.

These figures describe different operating conditions. Rated torque is relevant to continuous operation, while maximum torque is generally associated with shorter-duration demands subject to the motor and drive limits. Motor selection should be based on the actual load profile, including starting torque, acceleration, deceleration, and operating duty cycle.

3.3 Holding brake

The 1SH0 configuration includes an integrated permanent-magnet holding brake. Its listed holding torque is approximately 13 Nm, and it uses a 24 V DC supply.

The brake is intended primarily to hold the motor shaft when the motor is stopped. It should not automatically be treated as a substitute for a service brake used for frequent dynamic stopping. For vertical axes or gravity-loaded mechanisms, the machine designer must assess the load, transmission ratio, brake capacity, stopping method, and safety requirements.

3.4 Dimensions and weight

The motor has a 63 mm shaft-height classification and a listed net weight of approximately 12.802 kg.

The shaft height is not the complete external size. For mechanical installation, the exact drawing should be used to verify motor length, flange dimensions, mounting-hole spacing, shaft diameter, shaft extension, and connector clearance. This is especially important when replacing a motor in an existing machine.

4. Product Introduction

The 1FK7063-5AF71-1SH0 is an industrial synchronous servo motor designed to operate as part of a controlled-motion system. The motor converts electrical power into rotational movement, while the servo drive regulates the current supplied to the motor according to commands from the motion controller.

Its resolver provides rotor-position feedback, allowing the drive to monitor motor movement and regulate operation. This is useful in systems where speed consistency, controlled acceleration, and repeatable positioning are important.

The motor’s compact frame allows it to be integrated into industrial equipment where space is limited. Natural cooling simplifies the motor’s cooling arrangement, while the plain shaft provides a direct mechanical interface for a suitable coupling or transmission component.

An integrated holding brake provides an additional function for applications where the motor shaft must be held while stopped. The brake must be correctly connected and controlled, and the machine’s safety system must be designed around the actual load and stopping requirements.

The IP64 enclosure rating offers protection against dust ingress to the specified level and against water splashes under defined test conditions. It is not intended to indicate suitability for immersion or high-pressure washdown.

As with other servo motors, the final performance depends on the complete system. The motor must be matched with a compatible servo drive, suitable feedback wiring, a correctly sized mechanical transmission, and appropriate control parameters.

5. Product Applications

5.1 CNC machine tools

The motor can be considered for feed axes, rotary positioning mechanisms, and auxiliary movements in CNC machinery. Its feedback-based control supports controlled movement and repeatable positioning when the mechanics and drive are properly configured.

5.2 Packaging and filling machinery

Packaging systems often require coordinated motion across conveyors, feeders, rollers, and indexing mechanisms. A servo motor can regulate movement sequences and acceleration to help achieve consistent machine cycles.

5.3 Automated assembly lines

Automated assembly equipment may use servo motors for positioning slides, transfer mechanisms, rotary tables, and component-feeding devices. Controlled movement helps coordinate individual stations and maintain repeatable part placement.

5.4 Material handling and transfer equipment

The motor may be suitable for selected transfer mechanisms and positioning systems. Application sizing should account for moving mass, acceleration, transmission ratio, friction, and required cycle time.

5.5 Printing and converting machinery

Servo-controlled rotation can be useful for roller drives, feeding mechanisms, and synchronized machine sections. The required speed range, load inertia, and tension-control method should be considered before selecting the motor.

5.6 Textile machinery

Textile equipment can require controlled feeding, winding, positioning, and coordinated movement. Motor selection should account for continuous operating time, load variation, and the frequency of acceleration and deceleration.

5.7 Automated inspection and test systems

The motor can be used in positioning mechanisms that move a component, fixture, or test assembly to a defined location. The achievable accuracy depends on the complete system, including mechanical rigidity, feedback resolution, control tuning, and external measurement equipment.

5.8 Rotary indexing and positioning equipment

Rotary tables and indexing mechanisms require controlled angular movement and repeatable stopping positions. A servo motor may provide the required motion when its torque and inertia characteristics match the application.

These are potential application categories for this motor class. Suitability for a specific machine must be confirmed through torque, speed, duty-cycle, environmental, and safety calculations.

6. Main Advantages

6.1 Feedback-based motion control

The resolver provides position feedback to the servo drive. This enables closed-loop regulation of motor movement and supports consistent speed control, controlled acceleration, and repeatable positioning.

6.2 Integrated holding brake

The integrated permanent-magnet holding brake can help hold the shaft when the motor is stopped. This can be useful in positioning systems where unintended shaft movement must be prevented during a stop or power-off condition.

The brake must be sized for the actual load and transmission ratio. It should not be assumed to provide emergency stopping capability unless the complete machine design specifically supports that function.

6.3 Compact construction

The 63 mm shaft-height class allows the motor to be incorporated into many compact machine assemblies. A smaller installation envelope can simplify machine layout, although space must still be provided for connectors, cables, and mechanical coupling.

6.4 Suitable power and speed range

The approximately 2.29 kW operating power and 3,000 rpm rated speed make the motor a potential choice for industrial feed axes, positioning mechanisms, and automated equipment. The final selection should be based on the continuous load and required acceleration profile.

6.5 Flexible mechanical integration

The plain shaft can be connected to a suitable coupling or transmission component. The selected coupling should match the shaft dimensions, torque demand, operating speed, and allowable alignment error.

6.6 Natural cooling

Natural cooling avoids the need for a separate motor cooling fan in the standard configuration. Adequate heat dissipation must still be maintained, particularly when the motor operates continuously or experiences frequent high-torque cycles.

6.7 Industrial enclosure protection

The IP64 rating provides defined protection against dust and water splashes. This is useful in suitable factory environments, but the motor should not be exposed to immersion, high-pressure cleaning, or other conditions outside its specified rating.

6.8 Maintenance and replacement planning

The complete ordering code helps technicians distinguish the required feedback, brake, shaft, and connector configuration. Recording the model and installation dimensions can make future replacement work more predictable and reduce the risk of selecting an incompatible motor.

7. Five Related Models in the Same Series

The following models belong to the same general 1FK7 motor family or share a closely related motor platform. The configurations are not identical, so each candidate should be checked before replacement.

The power and speed figures above describe the shared motor platform. Encoder options may affect the available performance, and the exact ratings should be checked for the individual order code.

How these related models differ

• 1FK7063-5AF71-1SA0: Similar resolver-based feedback, but it does not have the integrated holding brake and uses a fitted-key shaft.

• 1FK7063-5AF71-1FH0: Uses a DRIVE-CLiQ absolute encoder and includes a holding brake. It may suit a compatible control system that requires this feedback interface.

• 1FK7063-5AF71-1AG0: Uses incremental feedback and has a plain shaft, but no integrated holding brake.

• 1FK7063-5AF71-1EB2: Uses EnDat absolute feedback and a fitted-key shaft, with a different protection configuration.

• 1FK7063-5AF71-1GB0: Provides basic absolute feedback and a holding brake, subject to drive compatibility.

The closest mechanical alternative is not necessarily the best electrical alternative. Feedback interface, shaft type, brake, protection rating, and drive parameters should all be considered.

8. Five Other Models to Consider from the Same Brand

The models below provide a broader shortlist across industrial servo-motor families. They are alternatives to investigate rather than a verified ranking of the most popular models.

For these five models, the full order code and individual technical data are necessary to establish exact power, torque, speed, dimensions, and weight. Do not assume that two motors from the same brand can use the same drive parameters or mechanical mounting.

10. Installation and Maintenance Recommendations

Mechanical installation

Check the mounting flange, bolt pattern, shaft extension, coupling, and alignment before installing the motor. Incorrect alignment can increase bearing loads, create vibration, and reduce service life.

Allow sufficient room for the connectors and cables. Cable routing should not create strain at the connector or interfere with nearby moving components.

Electrical connection

Confirm that the servo drive is compatible with the motor’s electrical characteristics and resolver feedback. Use the correct power and feedback cables, and verify connector pin assignments before commissioning.

Electrical work should be performed only after the equipment has been safely isolated and the relevant safety procedures have been followed.

Holding-brake operation

The integrated holding brake should be connected and controlled according to the motor and drive requirements. Verify the brake’s supply voltage, holding torque, and control sequence.

For a vertical axis or other gravity-loaded mechanism, assess the full load-retention and safety requirements. The holding brake alone should not be assumed to provide every safety function required by the machine.

Thermal management

Monitor motor temperature under representative operating conditions. Excessive load, frequent acceleration, unsuitable drive settings, and inadequate heat dissipation can cause overheating.

Routine inspection

Inspect the motor, coupling, connectors, cables, and mounting hardware periodically. Investigate unusual noise, vibration, inconsistent positioning, or repeated drive faults rather than assuming the motor is the source of every problem.

Replacement planning

Record the full motor code, nameplate details, drive model, cable arrangement, and mechanical dimensions. These details are useful when sourcing a replacement or troubleshooting an existing installation.
