1FK7042-2AK71-1RB0 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S 1FK7042-2AK71-1RB0 is a high-precision, high-performance synchronous motor engineered for demanding industrial applications. With a rated power of 0.94 kW and a nominal torque of 3 Nm, this compact unit delivers exceptional efficiency and motion accuracy. Its naturally cooled IMB 5 design with flange mounting (IM V1, IM V3) ensures reliable operation in environments where space and performance are both critical. The rotatable power connector, IP64 protection, and integrated holding brake make it ideal for continuous, high-speed duty cycles up to 6000 rpm.

Equipped with an AM20DQI 20-bit + 12-bit multi-turn absolute encoder using Drive-CLiQ interface technology, this model provides accurate position feedback and enhanced communication between the motor and SIEMENS SINAMICS drives. The motor’s robust mechanical structure, combined with low noise and vibration levels, ensures superior reliability and operational stability across a wide range of automation systems.

Overview

The SIMOTICS S-1FK7 series is a family of compact, permanent-magnet synchronous motors known for their adaptability and consistent torque performance. Designed for integration with SIEMENS SINAMICS S120/S220 drive systems, these motors enable advanced speed and position control while maintaining energy efficiency. They can operate without external cooling, as the heat is dissipated through the motor surface, ensuring long service life and minimal maintenance requirements. This series meets the evolving demands of modern machinery through its flexible configuration options and precision engineering.
