1FK7042-2AF71-1RH1-ZK23 SIEMENS Exclusive SIMOTICS S-1FK7 Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S-1FK7 motor with product code 1FK7042-2AF71-1RH1-ZK23 is a premium compact synchronous servo motor engineered for advanced automation environments. Delivering a nominal power of 0.82 kW and a torque of 3 Nm at 3000 r/min, it provides precise and reliable performance for dynamic motion control applications. The design features a 600 V DC supply, natural cooling, IMB 5 construction, and a plain shaft with standard tolerance N. Equipped with a high-resolution AM20DQI multiturn encoder with DRIVE-CLiQ interface, this motor guarantees exceptional positioning accuracy and feedback consistency in every operation.

Overview

The SIMOTICS S-1FK7 series represents a new generation of permanent-magnet synchronous motors offering an optimal balance of compactness, power density, and efficiency. These motors integrate seamlessly with SINAMICS S120 or S220 drive systems, forming a high-performance automation solution for modern machine tools and industrial equipment. Built for operation without external cooling, heat is dissipated effectively through the motor housing, ensuring reliable long-term operation and minimal maintenance needs. The robust IP65 protection level and anthracite primer paint finish provide extra durability against environmental stress.

Design and Benefits

The 1FK7042-2AF71-1RH1-ZK23 belongs to the compact line within the SIMOTICS S-1FK7 family, providing high torque in a space-saving footprint. It features a rotatable power connector for flexible installation and a built-in holding brake for additional safety during precision stops. The motor’s extremely low rotor inertia enables fast acceleration and deceleration, making it ideal for tasks requiring rapid movement and repeatable precision. Its advanced construction ensures smooth, quiet operation, reducing vibration and improving control accuracy in demanding industrial applications.

Typical use cases include automation cells, robotics, packaging lines, textile production, and CNC machine tools. Combined with Siemens’ proven drive technology, this synchronous servo motor helps improve productivity, energy efficiency, and system reliability across a wide range of applications.
