Siemens 1FK7101-5AF71-1AG0 Servo Motor

Applications

The Siemens 1FK7101-5AF71-1AG0 Servo Motor is part of the Siemens 1FK7 family of permanent-magnet synchronous servo motors, developed for industrial motion-control applications requiring accurate positioning, controlled speed, and repeatable movement. When paired with a compatible servo drive and automation controller, it can support coordinated motion in a range of industrial machines.

Typical application areas include:

• CNC Machine Tools: Supports controlled axis movement and repeatable positioning in automated machining operations.

• Packaging Machinery: Helps coordinate feeding, filling, sealing, and product-handling movements when correctly sized for the application.

• Automated Assembly Equipment: Supports controlled motion in assembly stations and production machinery.

• Material Handling Systems: Can be integrated into suitable servo-driven handling mechanisms and automated equipment.

• Printing and Converting Machinery: Supports synchronized movement in applications requiring coordinated machine axes.

• General Industrial Automation: Provides servo motion for machines that require controlled acceleration, speed regulation, and positioning.

Application suitability depends on the motor's verified torque and speed ratings, electrical characteristics, feedback interface, mechanical configuration, and drive compatibility.

Key Advantages

1. Accurate Positioning

The Siemens 1FK7 servo motor family is designed for motion-control tasks requiring repeatable positioning. When paired with an appropriately configured drive and controller, the motor can support precise movement in automated machinery.

2. Responsive Motion Performance

Servo systems can respond to changing speed and position commands, making them useful for applications with frequent acceleration, deceleration, and positioning cycles. Overall performance depends on motor sizing, drive tuning, and machine mechanics.

3. Integration with Industrial Automation

The motor can be incorporated into compatible servo-drive and control architectures. For Siemens-based installations, confirm the appropriate drive configuration and motor data before commissioning.

4. Broad Application Potential

Servo motors are widely used in packaging, machine tools, assembly equipment, and material handling systems. The 1FK7 family offers options for different motion-control requirements, subject to individual model specifications.

5. Clear Identification for Replacement

The complete ordering code helps distinguish motor configurations during maintenance and procurement. Matching the full code is important because similar-looking motors may differ in winding, feedback, connection, or mechanical details.

6. Defined Mechanical Reference

The specified 100 mm shaft height provides an initial reference for equipment integration. A complete fit assessment must also consider shaft dimensions, mounting geometry, connectors, and available installation space.
