Siemens SIMOTICS S-1FK7 Synchronous Servo Motor About

The Siemens 1FK7040-5AK71-1EG0 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 1FK7040 frame size provides a compact and robust industrial servo-motor solution with high power density and excellent dynamic response. The -5AK71 configuration defines the motor's electrical, mechanical, and cooling characteristics, while -1EG0 identifies the specific motor configuration. The motor is intended for integration with compatible Siemens SINAMICS drive systems, providing responsive servo control, precise positioning, 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, rapid acceleration and deceleration, and repeatable motion performance.

For the exact 1FK7040-5AK71-1EG0 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 1FK7040 variant.
