1FK7042-2AF21-1RG1-ZJ09 SIEMENS Exclusive SIMOTICS S-1FK7 Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S-1FK7 synchronous motor with part number 1FK7042-2AF21-1RG1-ZJ09 delivers premium performance, precision, and durability for advanced industrial automation. Designed as a compact, permanent-magnet motor, it provides exceptional energy efficiency, low maintenance requirements, and stable torque performance across a wide speed range. With a power rating of 0.82 kW and a nominal speed of 3000 rpm, it is ideally suited for applications demanding accuracy and consistent operation. The motor features a naturally cooled configuration, a smooth shaft, and an absolute encoder (20-bit + 12-bit multi-turn) with DRIVE-CLiQ interface for precise feedback and system integration.

Overview

The SIMOTICS S-1FK7 motor series represents a new generation of compact synchronous drives that combine high torque density with flexible configuration options. These motors can be perfectly matched to individual applications through a wide selection of encoders, gear units, and mounting variants. When paired with SINAMICS S120 or S220 drive systems, the result is a powerful, responsive, and intelligent motion-control solution for modern automation lines. The S-1FK7 motors are engineered for operation without external cooling—heat is dissipated through the motor surface, providing a simple yet effective thermal design that ensures long service life and reliable performance even under demanding duty cycles.

Benefits and Applications

The S-1FK7 Compact motors offer space-saving installation with excellent power density, making them ideal for universal machinery. High Dynamic variants provide rapid acceleration thanks to low rotor inertia, while High Inertia models ensure stable closed-loop control under variable loads. Typical applications include machine tools, robotics, handling systems, packaging lines, and production equipment in the wood, glass, ceramic, stone, textile, and printing industries. Combined with an ALPHA SP+ SP 075S-MF1 planetary gearing unit (1 stage, ratio 10, feather key), this motor offers precise motion and efficient power transmission for automated systems.
