1FK7042-2AF21-1CB0 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S synchronous motor with part number 1FK7042-2AF21-1CB0 is an advanced, high-precision servo motor engineered for superior efficiency and performance in modern automation systems. With a power rating of 0.82 kW and a nominal speed of 3000 rpm, this motor delivers stable torque output of 3 Nm under continuous operation. It features a natural cooling system and IP64 protection, ensuring reliable performance even in demanding industrial conditions. The integrated 24-bit + 12-bit multi-turn absolute encoder with DRIVE-CLiQ interface (encoder type AM24DQI) guarantees exceptional positioning accuracy and feedback precision. The rotatable power connector and holding brake enhance flexibility and operational safety, making this model ideal for precise motion control applications.

Overview

The SIMOTICS S-1FK7 series is designed as a family of compact, permanent-magnet synchronous motors built for accuracy, dynamic response, and durability. These motors can be perfectly adapted to a variety of machine configurations through numerous options, including gearbox interfaces and encoder selections. When combined with SINAMICS S120 or SINAMICS S220 drive systems, they form a powerful, fully integrated motion solution with enhanced functionality and system intelligence. The 1FK7-CT motors operate efficiently without external cooling, with heat dissipated directly through the motor housing, supporting high overload capabilities and long service life.

Design and Benefits

The SIMOTICS S-1FK7 Compact motors feature a robust, space-saving design that supports universal installation. They are well-suited for automation tasks requiring precision, dynamic control, and efficiency. Their high power density enables compact machine layouts without compromising torque output. With low rotor inertia, the High Dynamic variants achieve fast acceleration and rapid response, while the High Inertia models provide exceptional stability for fluctuating load conditions. Minimal commissioning effort and disturbance compensation make these motors ideal for demanding industrial applications.

Applications

Typical applications include machine tools, robotics, handling systems, and production equipment for wood, glass, ceramics, and textiles. They are also widely used in packaging, printing, and auxiliary drive systems requiring precise, repeatable motion. The 1FK7042-2AF21-1CB0 embodies Siemens’ engineering excellence, providing the performance and reliability required in high-precision manufacturing environments.
