1FK7040-2AK71-1QB1 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S 1FK7040-2AK71-1QB1 is a premium synchronous servo motor engineered for precision, efficiency, and durability in demanding industrial automation environments. It delivers a continuous power of 0.69 kW and operates at a rated speed of 6000 rpm, making it ideal for high-performance applications that require stability and responsiveness. With a natural cooling design and IP65 protection, this motor ensures reliable operation even in challenging environments. The integrated absolute encoder AS20DQI with DRIVE-CLiQ interface allows accurate position feedback and seamless integration with modern SIEMENS drive systems. Its flange-mounted IMB 5 structure, combined with a rotatable power connector and holding brake, provides flexibility and convenience during installation and operation.

Overview

The SIMOTICS S-1FK7 motor series represents the latest generation of compact permanent-magnet synchronous motors. These motors combine exceptional power density with high dynamic response, ensuring fast acceleration and precision across a broad range of automation tasks. Their modular configuration enables compatibility with various gearboxes and encoder types, making them suitable for nearly all mechanical and electrical system requirements. When combined with the SINAMICS S120 or S220 drive system, the 1FK7 series forms a robust motion control solution that supports speed and position regulation with high reliability. The integrated encoder systems are optimized for both torque control and precision feedback, supporting the highest demands of modern manufacturing.

Design and Benefits

The SIEMENS SIMOTICS S-1FK7 Compact motor line features an extremely compact design that allows space-saving installation in machinery. The high power-to-size ratio ensures energy-efficient performance while maintaining operational smoothness. Its naturally cooled housing efficiently dissipates heat through the surface, eliminating the need for external cooling systems. The series offers three design variants: Compact, High Dynamic, and High Inertia—each tailored to specific performance requirements. The Compact model is suited for universal applications, while the High Dynamic type provides ultra-fast acceleration due to a low rotor moment of inertia. The High Inertia version offers excellent closed-loop control stability, ideal for heavy or variable load conditions. The entire SIMOTICS S-1FK7 range minimizes commissioning efforts and ensures long-term reliability for continuous industrial use.

Application

This motor is widely used in machine tools, robotic systems, packaging machines, textile machinery, and precision automation processes. Its consistent performance, precision control, and flexible configuration make it the preferred choice for engineers aiming to enhance productivity while maintaining energy efficiency.
