1FK7042-2AF71-1CG0 SIEMENS Exclusive SIMOTICS S-1FK7 Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S-1FK7 synchronous motor with part number 1FK7042-2AF71-1CG0 is engineered for precision, reliability, and efficiency in demanding automation environments. Delivering a rated power of 0.82 kW at 600 V DC and a nominal torque of 3 Nm at 3000 rpm, this naturally cooled motor ensures consistent performance with excellent thermal management. Its compact structure, flange-mount design (IMB 5 / IM V1 / IM V3), and rotatable power connector make installation easy and flexible across multiple applications.

Equipped with a high-resolution 24-bit + 12-bit multiturn absolute encoder featuring DRIVE-CLiQ interface, the 1FK7042-2AF71-1CG0 delivers precise position feedback and superior motion control accuracy. The motor’s plain shaft offers smooth power transmission, while its IP64 protection rating safeguards against dust and splash water, ensuring long-term reliability in industrial settings. It is designed for operation without external cooling — dissipating heat directly through the motor housing for efficient, maintenance-free operation.

Overview

The SIMOTICS S-1FK7 motor series represents Siemens’ latest generation of compact permanent-magnet synchronous motors, perfectly suited for high-performance servo applications. Available in various configurations and combined with compatible encoders, these motors meet the evolving requirements of modern machines. When paired with the SINAMICS S120 or S220 drive systems, they form a high-efficiency solution offering dynamic response, precise control, and dependable torque delivery.

Each SIMOTICS S-1FK7 variant is optimized for specific use cases — Compact, High Dynamic, or High Inertia. The Compact type saves space while maintaining high power density. The High Dynamic version features minimal rotor inertia for rapid acceleration, while the High Inertia version ensures stable performance under fluctuating loads. All models deliver robust closed-loop control with minimal commissioning effort and exceptional smoothness during operation.

Applications

This versatile synchronous motor is ideal for machine tools, robotics, packaging systems, printing machines, and material-handling equipment. It also performs exceptionally in wood, glass, ceramics, and textile processing, where continuous, reliable operation and exact speed control are essential. Its compactness, flexibility, and consistent torque output make it a preferred choice for OEMs and automation integrators seeking long-lasting performance and energy efficiency.
