1FK7042-2AF71-1UB1 SIEMENS Exclusive SIMOTICS S-1FK7 Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S-1FK7 synchronous motor with the model number 1FK7042-2AF71-1UB1 represents the latest generation of compact, high-efficiency servo motors for precise motion control in modern industrial automation. Delivering a continuous rated power of 0.82 kW and a torque of 3 Nm at 3000 rpm, this naturally cooled motor ensures reliable operation and excellent performance consistency. With a holding brake, feather-key shaft, and resolver featuring DRIVE-CLiQ interface, it offers accurate feedback and stable performance even under demanding load conditions. Built to the IP65 protection standard, this motor is ideal for harsh industrial environments requiring durability and long service life.

Overview

The SIMOTICS S-1FK7 motor series combines compact dimensions with superior power density, enabling flexible installation even in space-restricted applications. Designed to work seamlessly with SINAMICS S120 and S220 drive systems, these motors form a dynamic and highly functional drive solution for advanced machine architectures. Each motor integrates an encoder system tailored for precise speed and position control, allowing for smooth and efficient automation. The motors are air-cooled by surface dissipation, removing the need for external fans and reducing maintenance overhead.

With its high overload capability and adaptable configuration options, the 1FK7 series is a dependable choice for continuous operation. Whether implemented in high-speed packaging lines or robotic arms, this motor ensures energy-efficient motion and stable control accuracy.

Design and Benefits

The 1FK7042-2AF71-1UB1 features a rotatable power connector and flange-mounted construction (IMB 5) that simplifies integration into existing assemblies. Its compact housing saves installation space without sacrificing mechanical strength. The motor family offers several versions — Compact, High Dynamic, and High Inertia — each optimized for specific performance profiles. These variants enable fast acceleration, smooth torque regulation, and robust closed-loop control in varying load conditions.

Key advantages include:

• Compact design with high torque-to-volume ratio
• Integrated resolver feedback for precise synchronization
• Reduced commissioning time and effortless setup with SINAMICS drives
• Low maintenance due to naturally cooled design
• Excellent energy efficiency and operational reliability

Applications

Typical fields of use include CNC machine tools, robotics, handling systems, and automation solutions in packaging, woodworking, glass and ceramics, textiles, and printing industries. The SIEMENS SIMOTICS S-1FK7 motor delivers stable performance and smooth dynamics wherever precision and dependability are critical.
