1FK7042-2AF71-1CH1-ZX50 SIEMENS Exclusive SIMOTICS S-1FK7 Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S-1FK7 motor with part number 1FK7042-2AF71-1CH1-ZX50 represents a highly efficient and compact synchronous servo motor designed for precision, performance, and reliability. Delivering 0.82 kW nominal power at 3000 rpm and a rated torque of 3 Nm, this motor operates with a 600 V DC supply and features a naturally cooled configuration for consistent thermal stability. The device includes a rotatable power connector, absolute encoder AM24DQI with 24-bit + 12-bit multiturn resolution, and a robust plain shaft with standard tolerance N, offering smooth and efficient torque transmission under varying load conditions.

Overview

The SIMOTICS S-1FK7 series consists of compact permanent-magnet synchronous motors engineered to meet the evolving requirements of modern automation. Each unit can be perfectly matched with SINAMICS S120/S220 drive systems for a complete motion-control solution. Thanks to integrated encoders for both position and speed control, these motors ensure exceptional feedback precision and rapid dynamic response. The 1FK7 Compact variant allows space-saving installation while maintaining excellent performance, making it an ideal choice for machine builders who demand reliability and high operational efficiency.

Design

Constructed with precision engineering, the 1FK7042-2AF71-1CH1-ZX50 features a high-grade mechanical design with an IP65 protection class for rugged environments. Its RAL 3004 Magenta paint finish enhances durability and corrosion resistance. The motor’s naturally cooled aluminum housing dissipates heat efficiently without external fans, reducing maintenance and ensuring long-term reliability. The optional holding brake adds an extra layer of control for safety-critical applications.

Compatible with a wide variety of machine configurations, this synchronous motor excels in machine tools, robotics, packaging systems, and material processing equipment. Its combination of low rotor inertia, high torque accuracy, and compact footprint make it the preferred choice for industries that prioritize precision, speed, and energy efficiency.
