Siemens SIMOTICS S-1FK2 Synchronous Servo Motor About

The Siemens 1FK2105-4AF10-1SB0 is a SIMOTICS S-1FK2 synchronous servo motor designed for compact, high-dynamic, and precise motion-control applications. It uses permanent-magnet synchronous motor technology to provide accurate speed, torque, and positioning performance and is intended for integration with compatible Siemens SINAMICS drive systems.

The 1FK2105 frame size provides a compact and robust servo-motor solution with high power density and rapid dynamic response. The -4AF10 configuration defines the motor's electrical, mechanical, and cooling characteristics, while -1SB0 identifies the specific feedback, shaft, brake, and connection configuration. The motor is suitable for CNC machine tools, robotics, automated production systems, handling equipment, packaging machinery, assembly systems, and precision positioning applications where repeatable and responsive motion is required.

Its permanent-magnet construction supports efficient servo operation, rapid acceleration and deceleration, and reliable continuous-duty performance. The compact design makes it particularly suitable for applications where installation space is limited while maintaining accurate motion control.

For the exact 1FK2105-4AF10-1SB0 MLFB, specifications such as rated power, rated torque, rated speed, encoder/feedback type, holding-brake specification, protection rating, dimensions, and weight should be verified against the Siemens-specific datasheet rather than inferred from another 1FK2105 variant.
