1FK7042-2AF71-1CH1-ZJ23 SIEMENS Exclusive SIMOTICS S-1FK7 Synchronous Motor Original Brand New

The SIEMENS 1FK7042-2AF71-1CH1-ZJ23 SIMOTICS S-1FK7 motor is a premium synchronous servo solution that combines compact construction with high-efficiency performance for precision automation tasks. Delivering 0.82 kW nominal power and 3 Nm torque at 3000 rpm, this naturally cooled motor provides superior power density and smooth control in demanding industrial environments. Designed with an integrated AM24DQI 24-bit + 12-bit multiturn absolute encoder and DRIVE-CLiQ interface, it ensures precise feedback and reliable positioning accuracy.

Engineered for universal applications, the SIMOTICS S-1FK7 series integrates seamlessly with the SINAMICS S120 and S220 drive systems to deliver optimized control dynamics and system flexibility. Its IP65-rated housing provides protection against dust and moisture, while the plain shaft with holding brake and ALPHA SP+ SP 075S-MF1 planetary gearing (1 stage, i = 5) delivers reliable torque transmission for continuous duty operation. The motor’s naturally cooled design efficiently dissipates heat through its surface, ensuring consistent thermal performance without external fans.

Overview

SIMOTICS S-1FK7 motors are compact, permanent-magnet synchronous motors designed to meet the growing demands of modern machine generations. With multiple configurations, encoder options, and gear combinations, these motors can be tailored to a wide range of automation needs. When paired with SINAMICS drives, they form a complete motion control system capable of high-speed, high-precision performance across various industrial sectors.

Design and Applications

The 1FK7 Compact motors are built for space-saving installations with exceptional power density and robust construction. High Dynamic variants offer rapid acceleration with low rotor inertia, while High Inertia versions provide stable operation under variable load conditions. This versatility makes the SIMOTICS S-1FK7 family ideal for machine tools, robotic arms, packaging lines, wood and textile machines, and other precise servo-driven applications. Each motor is optimized for minimal commissioning time, excellent closed-loop control, and reliable operation in continuous use.

Built on Siemens’ decades of motor innovation, the 1FK7042-2AF71-1CH1-ZJ23 ensures outstanding performance, durability, and compatibility with advanced automation systems worldwide. Its precise engineering delivers maximum efficiency and control for industries requiring consistent motion accuracy and long-term dependability.
