1FK7042-2AF71-1QA0 SIEMENS Exclusive SIMOTICS S-1FK7 Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S-1FK7 motor with part number 1FK7042-2AF71-1QA0 represents an advanced generation of compact synchronous servo motors built for precision, reliability, and long-term performance. This naturally cooled motor provides a nominal power of 0.82 kW and a torque of 3 Nm at 3000 rpm, ensuring stable and efficient motion in automation systems. Its robust IP64 protection and flexible rotatable power connector make it ideal for demanding industrial conditions where durability and flexibility are essential.

Featuring an integrated absolute single-turn 20-bit encoder with DRIVE-CLiQ interface, the 1FK7042-2AF71-1QA0 ensures accurate feedback and smooth position control. The shaft is equipped with a feather key and tolerance N, enabling secure mechanical coupling without a holding brake. Built for seamless integration, this motor pairs perfectly with the SINAMICS S120 / S220 drive systems to form a highly responsive servo solution for precision motion applications.

Overview

The SIMOTICS S-1FK7 family combines compact construction with superior energy efficiency and high dynamic performance. Each unit is designed for operation without external cooling, dissipating heat directly through the motor housing to maintain consistent thermal balance. This line of synchronous motors supports multiple encoder options, allowing users to match the configuration to their specific control requirements. With an impressive overload capacity, the 1FK7 series ensures reliability even under fluctuating or heavy loads.

These motors are particularly suitable for machine tools, robotics, packaging, textile processing, and material-handling systems. The wide product range covers compact, high-dynamic, and high-inertia versions, enabling precise adaptation to different industrial environments. Low rotor inertia provides excellent responsiveness, while strong torque control guarantees smooth operation. Their proven design results in minimal commissioning time and low maintenance requirements, helping users achieve long-term operational stability and efficiency.
