1FK7042-2AF21-1RH1 SIEMENS Exclusive SIMOTICS S-1FK7 Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S-1FK7 motor, model 1FK7042-2AF21-1RH1, represents a premium solution for precision motion control in industrial automation. Delivering a nominal power of 0.82 kW and a rated torque of 3 Nm at 3000 rpm, this naturally cooled synchronous motor ensures excellent performance and stability even under demanding conditions. With a 20-bit + 12-bit multi-turn DRIVE-CLiQ encoder (AM20DQI), smooth shaft, and integrated holding brake, it offers remarkable positioning accuracy and operational safety. Built with IP65 protection and a robust IMB5 construction, it performs reliably in environments where durability and long service life are essential.

Overview

The SIMOTICS S-1FK7 family combines compact design with high torque density, enabling efficient installation even in space-restricted machines. When paired with the SINAMICS S120 or S220 drive systems, it forms an advanced motion platform offering precise control, fast response, and exceptional energy efficiency. Designed for surface cooling, the motor efficiently dissipates heat through its housing, eliminating the need for external cooling equipment and reducing maintenance overhead.

Design & Performance

This servo motor features a lightweight yet rigid construction that enhances responsiveness while minimizing vibration. The rotatable power connector allows flexible cable routing, and the integrated absolute encoder ensures accurate position feedback for synchronized multi-axis motion. Offering superior overload capacity and seamless integration into automation architectures, the 1FK7042-2AF21-1RH1 delivers consistent performance across diverse applications such as robotics, packaging, woodworking, textile production, and precision machine tools.

Applications & Benefits

• Ideal for robots, handling systems, and CNC machinery
• Space-saving installation through exceptional power-to-size ratio
• High dynamic response with low rotor inertia
• Reliable closed-loop control for heavy or variable load conditions
• Low maintenance and easy commissioning through standardized interfaces
