1FK7042-2AK71-1RA0 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S 1FK7042-2AK71-1RA0 is a high-precision synchronous motor engineered for exceptional speed control and efficiency in modern industrial automation systems. Built with superior mechanical integrity, this model delivers a rated power of 0.94 kW and a rated torque of 3 Nm at 6000 rpm. It is designed for natural cooling and constructed in an IMB 5 mounting design, suitable for both IM V1 and IM V3 positions. The rotatable power connector and Drive-CLiQ compatible encoder ensure seamless integration with SINAMICS drive systems, providing a reliable and flexible automation solution.

This advanced synchronous motor is part of the renowned SIMOTICS S-1FK7 family — compact permanent-magnet motors known for their high torque density, outstanding precision, and extended service life. The 1FK7042-2AK71-1RA0 variant is IP64 rated, ensuring excellent protection against dust and splashing water, making it ideal for demanding production environments. Its 20-bit + 12-bit multi-turn absolute encoder (AM20DQI) enhances position feedback accuracy, ensuring smooth and repeatable performance under continuous operation.

Overview

SIMOTICS S-1FK7 motors are compact, high-performance synchronous motors optimized for dynamic and precise motion control. These motors can be perfectly adapted to a wide variety of industrial applications thanks to the diverse selection of shaft types, encoders, and gear options. When paired with SINAMICS S120 or S220 drives, the combination forms a complete motion system with advanced functionality, scalability, and diagnostic capabilities. Heat dissipation occurs naturally through the motor surface, eliminating the need for external cooling systems while maintaining high thermal efficiency and overload capacity.
