1FK7040-2AK71-1FG1-ZJ17 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S 1FK7040-2AK71-1FG1-ZJ17 is a high-precision synchronous servo motor that delivers outstanding torque stability, dynamic performance, and energy efficiency. Designed for modern automation environments, it combines compact construction with excellent mechanical durability, ensuring consistent performance across diverse industrial applications. With a rated power of 0.69 kW, torque of 1.6 Nm (100 K), and a speed of 6000 rpm, this motor guarantees reliable motion control for precision machinery. The naturally cooled frame in IMB 5 (IM V1, IM V3) configuration allows flexible installation in confined spaces, while its rotatable power connector enhances accessibility during integration.

Overview

SIMOTICS S-1FK7 motors are compact, permanent-magnet synchronous units engineered to provide superior precision and adaptability. The 1FK7 series integrates seamlessly with SINAMICS S120 and S220 drive systems, forming a powerful motion platform that enables efficient, intelligent control across multiple axis configurations. The embedded 22-bit + 12-bit multiturn absolute encoder with DRIVE-CLiQ interface (AM22DQ) offers precise position and speed feedback, improving motion accuracy while reducing commissioning time. The high overload capacity and direct heat dissipation through the motor surface extend service life and ensure dependable operation even under intensive duty cycles.

Design and Benefits

This version of the 1FK7 motor includes a plain shaft with tolerance N and IP65 protection, offering resilience against dust and moisture. Coupled with an ALPHA SP+ SP 100S-MF2 planetary gear unit (2 stages, ratio 50:1 with feather key), it provides high torque multiplication and smooth rotational transmission. Compact dimensions and high power density minimize installation space, while flexible mounting enables integration into robotics, packaging, and CNC machinery. The motor’s low rotor inertia ensures fast response and stable closed-loop control in applications requiring rapid positioning and speed changes.

Applications

Typical applications include machine tools, robots and handling systems, wood, glass, ceramics and stone processing equipment, packaging and textile machines, printing units, and auxiliary axes in automation systems. By delivering reliable performance and precise control, the 1FK7040-2AK71-1FG1-ZJ17 supports the demands of today’s high-speed production lines and advanced manufacturing technology.
