1FK7040-2AK71-1RH1-ZJ23 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S 1FK7040-2AK71-1RH1-ZJ23 is a high-performance synchronous servo motor designed to deliver exceptional precision, reliability, and long-term efficiency in industrial automation. It provides an output power of 0.69 kW and operates at 6000 rpm with a torque rating of 1.6 Nm, perfectly suited for demanding motion control applications. The naturally cooled construction and IP65 degree of protection ensure optimal operation under challenging environmental conditions. Featuring a rotatable power connector, smooth shaft, and integrated holding brake, this motor combines robust engineering with modern usability for a wide range of automation systems.

Overview

The SIMOTICS S-1FK7 motor series is known for its compact design and high power density, making it an ideal solution for modern industrial machinery that requires accurate and dynamic motion control. These motors are permanent-magnet synchronous types that offer efficient performance, smooth operation, and excellent torque-to-weight ratio. The range of encoders and gearboxes available allows the system to be precisely configured for various applications, while compatibility with the SINAMICS S120/S220 drive system enhances system integration and overall functionality. With integrated encoder systems such as the 20-bit + 12-bit multi-turn absolute encoder (AM20DQI) using DRIVE-CLiQ interface, the motor ensures precise position and speed feedback for superior control accuracy.

Design

The 1FK7040-2AK71-1RH1-ZJ23 motor includes a J23 ALPHA SP+ SP 075S-MF1 planetary gearing (1 stage, i=5) configuration, offering excellent torque transmission and smooth performance without the use of a feather key. Its compact IMB 5 mounting design (IM V1, IM V3) allows easy installation in space-limited applications. The robust mechanical design guarantees durability, while the motor’s natural cooling system provides efficient thermal management. Thanks to its low rotor moment of inertia, the system delivers rapid acceleration and deceleration, ideal for dynamic industrial processes. These design aspects make the SIMOTICS S-1FK7 series both powerful and energy-efficient, contributing to long-term operational reliability and reduced maintenance requirements.

Applications

The 1FK7040-2AK71-1RH1-ZJ23 is suitable for a wide range of industrial uses, including machine tools, robotic systems, packaging and printing equipment, as well as wood, glass, ceramics, and stone processing machinery. It is also frequently used in auxiliary axes where high precision and repeatability are critical. With its consistent performance and adaptability, this motor supports both compact system integration and high-speed dynamic applications, setting a benchmark in motion technology.
