1FK7043-4CH71-1UA0 SIEMENS Exclusive High-Precision Synchronous Servo Motor Original Brand New

The SIEMENS 1FK7043-4CH71-1UA0 is a member of the advanced SIMOTICS S-1FK7 motor family, engineered to provide high torque density, precise performance, and exceptional reliability in demanding industrial environments. With a rated power output of 1.2 kW and a rated speed of 4500 rpm, this synchronous motor ensures accurate motion control and smooth operation across a wide variety of automation applications. The motor’s compact, naturally cooled design and IP64 protection class make it ideal for integration into machine tools, handling systems, and automated production lines.

It features a rotatable power connector, a shaft with fitted key, and a multi-pole resolver with DRIVE-CLiQ interface, offering enhanced connectivity and streamlined installation.

Overview

The SIMOTICS S-1FK7 series represents a new generation of permanent-magnet synchronous motors designed for energy efficiency and mechanical precision. Thanks to its compact dimensions and high torque density, the 1FK7043-4CH71-1UA0 can be easily incorporated into confined spaces without sacrificing performance. When paired with SINAMICS S120 or S220 drive systems, this motor forms a complete high-performance servo solution for automation tasks that demand quick response and reliable torque output.

The integrated encoder systems enable accurate speed and position control, making it suitable for continuous operation where precision and durability are essential. Its ability to dissipate heat through its motor surface allows for operation without external cooling, maintaining steady thermal performance even under intensive load cycles.

Benefits

• Compact construction with extremely high power density for space-saving machine integration.
