1FK7042-2AF71-1RB1-ZY84 SIEMENS Exclusive SIMOTICS S-1FK7 Compact Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S-1FK7 motor is a premium-grade synchronous servo motor engineered for precision, durability, and performance. With a rated power of 0.82 kW and a rated speed of 3000 r/min, this compact model combines exceptional torque delivery (3 Nm at 100 K) with excellent energy efficiency. It operates on 600 V DC and features a naturally cooled design in construction type IMB5 (IM V1, IM V3) with flange 1, ensuring efficient heat dissipation during continuous operation. The integrated absolute encoder (AM20DQI, 20 + 12-bit multiturn Drive-CLiQ) provides precise feedback for advanced position and speed control. Designed for reliability in demanding industrial environments, this motor features IP65 protection and includes a holding brake and rotatable power connector for flexible installation.

Overview

The SIMOTICS S-1FK7 series from SIEMENS represents the next generation of compact permanent-magnet synchronous motors. These motors are optimized for applications requiring high accuracy, fast response, and compact dimensions. They integrate seamlessly with SINAMICS S120 and S220 drive systems, forming a powerful, intelligent automation solution. Each motor offers multiple encoder and mechanical configuration options, enabling engineers to select the ideal configuration for virtually any machine architecture. Designed for operation without external cooling, the S-1FK7 series dissipates heat effectively through the motor surface, ensuring consistent performance even under high load conditions.

Design and Advantages

The 1FK7042-2AF71-1RB1-ZY84 features a robust shaft with feather key (tolerance N) and a rugged mechanical housing designed for extended service life. This compact servo motor minimizes installation space while maximizing mechanical power density. The compact design supports universal applications such as packaging machinery, robotics, material handling, woodworking, and textile production. Advanced rotor technology ensures low inertia, delivering high dynamic response and accurate positioning. Meanwhile, the high-inertia variants within the same series provide superior control for systems with variable load moments.

The SIMOTICS S-1FK7 family offers a complete portfolio to match high-speed, high-precision automation environments, supporting simplified commissioning, reliable motion control, and seamless digital integration. Whether in machine tools, robotic arms, printing systems, or auxiliary axes, this motor delivers the dependable performance and flexibility expected from SIEMENS engineering.
