The SIEMENS SIMOTICS S 1FK7040-2AK71-1QA0 is a high-performance synchronous servo motor designed for precision, reliability, and durability in industrial automation. With a rated power of 0.69 kW and a rated speed of 6000 rpm, this motor ensures smooth and efficient operation in dynamic environments.

Its compact construction, robust materials, and naturally cooled design make it ideal for integration into modern manufacturing systems that demand consistent torque delivery and low maintenance. Engineered for optimal compatibility with SINAMICS S120/S220 drive systems, the 1FK7040-2AK71-1QA0 guarantees superior motion control and operational efficiency in various industrial applications.

Overview

SIMOTICS S-1FK7 motors are compact permanent-magnet synchronous motors developed by SIEMENS to provide a perfect balance between power density, performance, and flexibility. With a wide selection of mechanical designs, encoders, and gear options, the 1FK7 series meets the diverse requirements of today’s industrial machinery.

Designed for operation without external cooling, the heat generated during use is effectively dissipated through the motor surface, ensuring stable operation even under continuous load conditions. The 1FK7 family is known for its outstanding overload capacity, high torque consistency, and long service life, offering unmatched reliability for machine builders and automation engineers worldwide.

Design and Benefits

The 1FK7040-2AK71-1QA0 motor features a precision-engineered shaft with a feather key, an IP64 protection rating, and a rotatable power connector for flexible installation. It includes an absolute single-turn encoder (20-bit, DRIVE-CLiQ interface) for accurate position feedback, enhancing system responsiveness and stability. This motor is available without a holding brake, simplifying maintenance and reducing downtime. As part of the SIMOTICS S-1FK7 Compact range, it enables space-saving installations due to its high power density, making it suitable for universal applications.

For users requiring precise control, the High Dynamic variant offers exceptional response due to a low rotor moment of inertia, while the High Inertia version provides stable closed-loop control for fluctuating load conditions. Typical applications include machine tools, robotics, packaging, plastics, and textile machines.
