Siemens SIMOTICS S-1FK7 Synchronous Servo Motor About

The Siemens 1FK7103-5AF71-1UH0 is a SIMOTICS S-1FK7 synchronous servo motor designed for high-performance, precise, and dynamic motion-control applications. It uses permanent-magnet synchronous motor technology to provide accurate speed, torque, and positioning performance, making it suitable for CNC machine tools, robotics, automated production systems, material-handling equipment, packaging machinery, and precision positioning applications.

The 1FK7103 frame size provides a robust industrial servo-motor solution with high power density and excellent dynamic response. The -5AF71 configuration defines the motor's electrical, mechanical, and cooling characteristics, while -1UH0 identifies the specific motor configuration. The motor is intended for integration with compatible Siemens SINAMICS drive systems, providing responsive servo control, precise positioning, rapid acceleration and deceleration, and reliable continuous-duty operation.

Typical applications include CNC axes, machine tools, robotics, material handling, assembly systems, packaging equipment, production automation, and precision positioning systems. Its permanent-magnet construction supports efficient servo operation and repeatable motion performance.

For the exact 1FK7103-5AF71-1UH0 MLFB, specifications such as rated power, rated torque, rated speed, encoder/feedback type, holding brake, IP protection rating, dimensions, and weight should be verified against the Siemens-specific datasheet rather than inferred from another 1FK7103 variant.
