Siemens 1FK7063-5AF71-1SG0 Servo Motor

1. Product Overview

The 1FK7063-5AF71-1SG0 belongs to the SIMOTICS S-1FK7 family of compact synchronous servo motors. It is designed for industrial motion-control applications that require controlled rotation, repeatable movement, and accurate coordination with a compatible servo drive.

Servo motors are widely used in automated machinery because they can regulate torque, speed, and position through a feedback-based control system. Depending on the machine configuration, they may drive feed axes, transfer mechanisms, rotary positioning tables, packaging equipment, and other mechanical assemblies.

The motor’s complete ordering code is important when selecting a replacement. Models within the same series may have different feedback devices, shaft designs, holding brakes, connectors, protection ratings, and electrical characteristics. A similar-looking motor is not necessarily a direct replacement.

Technical accuracy note: The general series characteristics can be described, but not every specification for the exact 1FK7063-5AF71-1SG0 configuration can be independently confirmed here. Unverified values are identified below rather than presented as guaranteed specifications. In particular, the final dimensions and weight should be confirmed using the nameplate and the exact dimensional drawing.

2. Brand and Product Series

The 1FK7 series is intended for applications where a compact motor must provide controlled movement and reliable feedback to the drive system. The family includes different motor sizes and configurations, allowing engineers to select a model according to torque, speed, installation space, feedback requirements, and mechanical load.

The resolver-based feedback arrangement is a key consideration for the SG0 configuration. The replacement drive must support the appropriate feedback interface, and the feedback cable and connector pinout must match the motor.

The absence of an integrated holding brake is also important. If the motor drives a vertical axis or a load that must remain stationary when electrical power is removed, the machine may need a separate holding mechanism or a suitable braking solution.

3. Technical Parameters

The following table summarizes the main specifications associated with this motor configuration. The rated torque and static torque are listed separately because they describe different operating conditions.

Understanding the rated torque

The 11 Nm figure is the motor’s approximate static torque at a specified temperature rise, not its rated continuous torque at 3,000 rpm. The rated torque is approximately 7.3 Nm under the stated 100 K temperature-rise condition.

This distinction matters when sizing the motor. Continuous load torque, acceleration torque, peak torque, operating speed, and duty cycle should all be considered. A motor that can briefly produce a required torque may not be able to sustain that torque continuously without exceeding its thermal limits.

Dimensions and weight

The 63 mm shaft height identifies the motor’s frame-size class. It does not specify the complete external dimensions of the motor.

For installation or replacement, obtain the exact drawing and verify the flange diameter, mounting-hole pattern, shaft diameter, shaft extension, motor body length, connector clearance, and cable-routing space. The weight is approximately 11.5 kg, but the exact figure should be confirmed against the specific unit’s technical documentation.

4. Product Description

The 1FK7063-5AF71-1SG0 is designed to convert electrical energy into controlled rotational motion. In a typical installation, the motor operates with a servo drive and motion controller. The controller sends movement commands, while the drive regulates motor current to produce the required torque and speed.

The resolver provides rotor-position feedback to the drive. This allows the control system to coordinate motor movement with the commanded operating profile. Depending on the system design, the motor can support controlled acceleration, deceleration, speed regulation, and positioning.

Its compact frame makes it suitable for machinery where installation space is limited. Natural cooling reduces the need for separate forced-air cooling hardware, although sufficient heat dissipation must still be maintained. The plain shaft provides a mechanical interface for a suitable coupling or transmission component.

The motor is intended for integration into a complete machine rather than standalone operation. Correct performance depends on drive compatibility, feedback wiring, mechanical alignment, load inertia, and appropriate commissioning settings.

The IP64 protection rating provides protection against dust ingress to the specified level and against water splashes under defined test conditions. It does not mean that the motor is suitable for immersion or high-pressure washdown.

5. Product Applications

5.1 CNC machines and machine tools

Servo motors are commonly used to drive machine-tool feed axes, rotary tables, positioning mechanisms, and auxiliary movements. The feedback system supports controlled movement and repeatable positioning when the motor is paired with a compatible drive and properly configured control system.

5.2 Packaging and filling machinery

Packaging systems frequently require synchronized movement of conveyors, feeding mechanisms, rollers, and product-positioning assemblies. Servo control allows the machine to coordinate movement sequences and adjust acceleration and speed according to the production cycle.

5.3 Automated assembly equipment

In assembly machinery, servo motors can drive transfer units, positioning slides, rotary indexing tables, and component-feeding mechanisms. Repeatable movement helps maintain consistent part placement and timing between machine stations.

5.4 Material-handling systems

Servo motors can be used in automated transfer mechanisms, conveyor positioning, and handling equipment. Motor selection should account for the weight of the moving load, transmission ratio, acceleration requirements, friction, and expected operating cycle.

5.5 Printing and converting machinery

Controlled motor rotation can support roller drives, material feeding, and synchronization between machine sections. The suitability of this model depends on the required speed range, load inertia, tension-control requirements, and drive capabilities.

5.6 Textile machinery

Textile equipment may use servo motors for controlled feeding, positioning, and coordinated mechanical movements. Proper sizing is important where the machine requires frequent acceleration or continuous operation over long production shifts.

5.7 Inspection and test equipment

Servo motors can drive positioning stages and rotary mechanisms used to bring a component or test fixture to a defined position. The required repeatability depends on the complete mechanical and control system, not just the motor.

These examples describe possible applications for this class of servo motor. The exact SG0 configuration should be selected only after checking its electrical, mechanical, and environmental suitability for the intended machine.

6. Product Advantages

6.1 Closed-loop motion control

Resolver feedback enables the drive to monitor rotor position and control motor movement. This supports consistent speed regulation and repeatable positioning when the system is configured correctly.

6.2 Compact installation

The 63 mm shaft-height class is useful for machinery that requires a compact motor footprint. The final installation space must still account for the motor body, connectors, cables, and coupling.

6.3 Natural cooling

The natural-cooling design avoids the need for a separate cooling fan in the standard motor configuration. This can simplify installation and reduce the number of auxiliary components, provided the motor operates within its thermal limits.

6.4 Industrial motion capability

The approximately 2.29 kW power class and 3,000 rpm rated speed make the motor a potential choice for industrial feed and positioning systems. The actual application must be sized using continuous torque, peak torque, inertia, speed, and duty-cycle calculations.

6.5 Plain-shaft connection

The plain shaft can be connected to a compatible coupling or transmission component. The selected coupling must match the shaft dimensions and transmitted torque, and it must accommodate the required alignment tolerances.

6.6 Flexible connector orientation

The connector arrangement can help simplify cable routing in compact machinery. Proper routing and strain relief remain necessary to prevent cable damage and interference with moving machine parts.

6.7 Dust and splash protection

The IP64 rating provides a defined level of protection against dust and water splashes. This can be useful in suitable industrial environments, but the motor should not be exposed to conditions beyond its specified protection limits.

6.8 Useful for maintenance of existing machinery

Identifying the complete motor code can help maintenance teams locate the correct replacement configuration. Checking the feedback system, shaft design, brake requirement, connectors, and mounting dimensions reduces the risk of ordering a mechanically similar but electrically incompatible motor.

7. Five Related Models in the Same Series

The following models are related to the 1FK7063-5AF71 family. They differ in feedback type, shaft design, holding brake, or protection configuration.

The figures shown describe the related motor platform and the listed configurations. Confirm the exact ratings and any configuration-dependent performance reduction before using a model in a machine.

Choosing a related model

• 1FK7063-5AF71-1AG0: Worth considering when an incremental SIN/COS encoder and a plain shaft are appropriate.

• 1FK7063-5AF71-1SA0: A resolver-based comparison model, but its fitted-key shaft differs from the SG0 plain shaft.

• 1FK7063-5AF71-1GB0: A candidate when absolute feedback and an integrated holding brake are required.

• 1FK7063-5AF71-1EB2: A candidate for systems requiring an EnDat absolute encoder and a different protection configuration.

• 1FK7063-5AF71-1FH0: Worth evaluating when a DRIVE-CLiQ absolute encoder and holding brake are required.

None of these should be assumed to be a direct replacement without checking the motor-drive combination, mechanical interface, and control requirements.

8. Five Other Models from the Same Brand

The following models provide additional options to investigate across compact servo motors and other industrial servo-motor families. They are comparison candidates, not a verified ranking of sales popularity.

These models do not share identical technical specifications. Their rated power, torque, speed, dimensions, feedback systems, and weights must be verified individually before they are used as alternatives.

9. Installation and Maintenance Considerations

Regular maintenance should include inspection of the mounting hardware, coupling, cables, connectors, and surrounding mechanical components. Abnormal vibration, unusual noise, rising temperature, or inconsistent positioning should be investigated rather than automatically attributed to motor failure.

Electrical inspections must be performed with appropriate isolation and safety procedures. Any replacement or reconnection should follow the relevant drive and machine commissioning requirements.

10. Final Summary

The 1FK7063-5AF71-1SG0 is a compact synchronous servo motor in the SIMOTICS S-1FK7 series. Its principal characteristics include approximately 2.29 kW optimal operating power, 3,000 rpm rated speed, 7.3 Nm rated torque at a 100 K temperature rise, approximately 11 Nm static torque at a 100 K temperature rise, 5.6 A rated current, natural cooling, resolver feedback, a plain shaft, no integrated holding brake, and IP64 protection.

Its main advantages are closed-loop motion control, a compact frame, natural cooling, and flexible integration into industrial machinery. Potential applications include CNC equipment, packaging machinery, automated assembly systems, material handling, printing equipment, and positioning mechanisms.

When selecting a replacement or related model, the most important factors are the exact shaft dimensions, mounting arrangement, feedback interface, brake requirement, protection rating, continuous torque, peak torque, and compatibility with the existing servo drive.

The overall dimensions should be taken from the drawing for the exact order code, and the motor weight should be confirmed against the supplied unit. This is especially important when the motor must fit an existing machine without mechanical modification.
