1FK7042-2AF71-1PB1 SIEMENS Exclusive SIMOTICS S-1FK7 Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S-1FK7 1FK7042-2AF71-1PB1 is a high-precision synchronous servo motor engineered for dynamic industrial performance and reliability. Designed with a rated power of 0.82 kW and a torque output of 3 Nm at 3000 rpm, this motor provides outstanding motion control for demanding applications. Its compact and naturally cooled construction ensures quiet operation, reduced maintenance, and long-term durability even under continuous duty conditions. With an IP65 protection rating and integrated holding brake, it delivers robust performance in harsh environments.

Overview

The SIMOTICS S-1FK7 series represents SIEMENS’ premium line of permanent-magnet synchronous motors, developed for high-efficiency automation. These motors are optimized for precise speed and position control through their integrated encoder systems and can be combined seamlessly with SINAMICS S120 / S220 drive systems. Their design allows flexible adaptation to a wide range of industrial requirements — whether for compact spaces, dynamic movement, or systems requiring precise torque regulation.

Constructed for natural convection cooling, the 1FK7 motors dissipate heat effectively through the housing, enabling stable thermal performance without additional cooling equipment. This results in energy-efficient operation and a long service life. The integrated DRIVE-CLiQ interface and 2-pole resolver ensure reliable communication with the drive system, while the feather-key shaft connection provides stable mechanical coupling for smooth power transmission.

Key Benefits and Applications

The SIMOTICS S-1FK7 series is available in Compact, High Dynamic, and High Inertia variants, allowing users to choose the ideal balance of speed, torque, and control precision. Compact models deliver high power density for space-restricted installations. High Dynamic versions excel in rapid-response environments thanks to their low rotor inertia, while High Inertia options provide exceptional control stability for variable load systems.

Typical applications include CNC machine tools, robotic arms, packaging lines, textile production, printing systems, and material-handling equipment. These motors provide precise positioning, smooth motion, and consistent power delivery, enabling manufacturers to achieve faster cycle times and improved production efficiency.
