1FK7042-2AF71-1CH1-ZJ17 SIEMENS Exclusive SIMOTICS S-1FK7 Compact Synchronous Motor Original Brand New

The SIEMENS 1FK7042-2AF71-1CH1-ZJ17 from the SIMOTICS S-1FK7 series represents the next level of precision and reliability in industrial automation. This synchronous motor delivers a rated power of 0.82 kW at 3000 r/min and a torque of 3 Nm, ensuring stable and consistent performance under demanding load conditions. Its naturally cooled, compact construction enables flexible installation in tight spaces while maintaining excellent thermal efficiency and long service life.

Equipped with a 24-bit + 12-bit multiturn absolute encoder using the DRIVE-CLiQ interface, the motor provides exceptional feedback accuracy for motion control systems. The plain shaft with N-tolerance, integrated holding brake, and IP65 degree of protection make it suitable for harsh industrial environments. Combined with the ALPHA SP+ SP 100S-MF2 planetary gear unit (ratio 50:1, with feather key), it delivers optimized torque transmission and smooth rotational output for dynamic applications.

Overview

The SIMOTICS S-1FK7 family includes compact permanent-magnet synchronous motors engineered for precision, reliability, and energy efficiency. Designed to operate seamlessly with SINAMICS S120 / S220 drive systems, these motors create an advanced servo solution with intelligent control and adaptive performance. Their integrated encoder systems allow precise position and speed control across diverse industrial sectors. Thanks to natural convection cooling, the heat is efficiently dissipated through the motor housing, eliminating the need for external cooling mechanisms.

Design and Benefits

The robust mechanical design of the 1FK7042-2AF71-1CH1-ZJ17 ensures consistent operation with minimal maintenance. High power density allows space-saving installation without compromising performance. The compact motor body and reinforced bearings deliver outstanding smoothness during acceleration and deceleration cycles. Users benefit from short commissioning times, reduced vibration, and excellent overload capacity.

This motor excels in applications such as CNC machinery, robotic arms, packaging systems, printing equipment, and precision handling systems. With its modular compatibility, engineers can select from multiple inertia variants — Compact, High Dynamic, or High Inertia — to match specific system demands. The result is an exceptionally versatile motion solution that combines dynamic responsiveness with superior energy efficiency and mechanical durability.
