1FK7042-2AF21-1RH0 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S synchronous motor 1FK7042-2AF21-1RH0 is a high-precision, compact servo solution engineered to deliver reliable torque and efficiency across a broad range of industrial motion control systems. With a rated power of 0.82 kW, a rated torque of 3 Nm, and a nominal speed of 3000 rpm, this naturally cooled motor provides consistent performance in demanding automation environments. Designed with an absolute encoder (20-bit + 12-bit multi-turn) and a DRIVE-CLiQ interface, it ensures precise feedback for smooth, synchronized operation. Its durable IP64 protection and smooth shaft construction guarantee reliable performance even under continuous duty conditions.

Overview

The SIMOTICS S-1FK7 series represents SIEMENS’ innovation in permanent-magnet synchronous motor technology, combining compact dimensions with exceptional dynamic behavior. These motors are compatible with SINAMICS S120/S220 drive systems, enabling a fully integrated servo solution with advanced control functionality. Depending on the configuration, encoders for both speed and position control can be selected to match application-specific requirements. Heat dissipation occurs efficiently through the motor surface, eliminating the need for external cooling systems and simplifying installation.

Offering a high overload capacity, the 1FK7 motors excel in maintaining stable operation under fluctuating loads, while their robust mechanical design minimizes vibration and mechanical wear. The precise rotor construction reduces inertia, ensuring faster acceleration and deceleration cycles, ideal for high-speed or repetitive industrial processes.

Design and Benefits

The SIMOTICS S 1FK7 Compact motor series delivers excellent space-saving installation due to its high power density and modular construction. It can be applied universally across numerous automation sectors.
The High Dynamic variant is optimized for rapid acceleration and deceleration, offering smooth and responsive performance in robotic or machine-tool applications, while the High Inertia variant ensures stable closed-loop control for systems with variable or heavy load inertia.

This motor is suitable for machine tools, packaging lines, handling systems, and industrial robots. It is also a dependable choice for machinery in wood, glass, ceramics, and textile processing, where precise torque and long-term reliability are essential. Its integration capability with SINAMICS drives allows seamless control architecture and simplified commissioning for OEMs and system integrators.
