1FK7042-2AF21-1BG2 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S 1FK7042-2AF21-1BG2 synchronous motor is an advanced industrial solution engineered for precision motion and long-term reliability. With a rated power of 0.82 kW and a rated torque of 3 Nm at 3000 rpm, this model combines compact dimensions with excellent dynamic performance. The naturally cooled, maintenance-free design ensures dependable operation even in demanding production environments. Its smooth shaft, IP65 degree of protection, and robust mechanical structure make it ideal for modern automation tasks requiring stable speed and positioning accuracy.

Overview

The SIMOTICS S-1FK7 motor series represents Siemens’ premium class of permanent-magnet synchronous motors, built for maximum versatility and energy efficiency. These motors can be perfectly matched with SINAMICS S120 or S220 drive systems to form a powerful servo solution for complex automation processes. Integrated encoder systems with absolute 24-bit resolution and DRIVE-CLiQ interfaces provide precise feedback for both speed and position control. Designed for operation without external cooling, the heat is effectively dissipated through the housing surface, ensuring high overload capacity and consistent performance under variable load conditions.

Benefits

The SIMOTICS S 1FK7 Compact motors are known for their exceptional power density, allowing space-saving installation and universal application flexibility. The High Dynamic variants offer extremely quick response due to a low-inertia rotor, while High Inertia models provide smooth control and excellent stability even with fluctuating load torques. These characteristics minimize commissioning effort and deliver superior process reliability. Whether in machine tools, robotics, packaging, or materials processing, the 1FK7042-2AF21-1BG2 ensures precise motion, long service life, and efficient energy use.

Application

Typical applications include advanced machine tools, industrial robots, automated handling equipment, woodworking and glass machining systems, as well as textile, packaging, and printing machinery. Wherever precise motion and consistent torque are essential, the SIMOTICS S 1FK7 series provides an optimal combination of performance, reliability, and efficiency.
