1FK7042-2AF71-1UA1 SIEMENS Exclusive SIMOTICS S-1FK7 Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S-1FK7 synchronous motor (1FK7042-2AF71-1UA1) is a high-performance drive solution engineered for precise motion control, energy efficiency, and durability in industrial environments. With a rated power of 0.82 kW and a rated speed of 3000 rpm, this compact motor delivers 3 Nm nominal torque under 600 V DC supply. The naturally cooled design with protection class IP65 ensures reliable operation in challenging applications, making it ideal for integration in modern automation systems where precision and responsiveness are critical.

Overview

The SIMOTICS S-1FK7 series consists of permanent-magnet synchronous motors that combine compact size, robust construction, and superior control performance. This family of motors offers a comprehensive range of mechanical and electrical options, allowing seamless adaptation to various industrial requirements. When paired with SINAMICS S120 or S220 drive systems, the S-1FK7 motors form a highly dynamic and efficient motion package suitable for applications demanding fast acceleration, stable speed regulation, and repeatable precision.

Each motor features integrated encoder systems with DRIVE-CLiQ interface for accurate position and speed feedback. The compact frame and feather-key shaft design simplify installation while minimizing space usage. The absence of a holding brake reduces complexity for continuous-duty applications. The excellent thermal design enables effective surface cooling without external fans, supporting long-term performance and low maintenance.

Design and Benefits

The 1FK7042-2AF71-1UA1 motor represents the Compact type (CT) within the S-1FK7 range. It is engineered for naturally cooled environments, featuring a rotatable power connector and multi-pole resolver for flexible configuration. Its advanced electromagnetic design allows high overload capability and low vibration during operation. As part of the SIMOTICS family, this motor ensures consistent performance, reduced commissioning effort, and optimal integration with motion controllers.

Typical applications include machine tools, robotics, packaging machinery, printing systems, and material-handling equipment. Industries such as wood, glass, ceramics, and plastics manufacturing rely on these motors for their stability, compactness, and fast dynamic response. The S-1FK7 motors are also valued for energy efficiency and precise torque output, which contribute to lower operating costs and improved productivity.
