1FK7042-3BK71-1BG1 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S 1FK7042-3BK71-1BG1 is an advanced permanent-magnet synchronous motor designed to deliver precision, reliability, and high-speed operation in a compact footprint. Engineered for dynamic industrial applications, this model offers a rated power of 0.94 kW at 600 V DC, with a nominal torque of 3 Nm and a top speed of 6000 rpm. The naturally cooled design with an IMB 5 (IM V1, IM V3) mounting configuration ensures effective heat dissipation and stable performance during continuous operation.

Built with a rotatable power connector, a smooth shaft with tolerance N, and an IP65 protection rating, the 1FK7042-3BK71-1BG1 motor ensures secure integration into demanding environments. The integrated 24-bit single-turn absolute encoder (AS24DQI) with DRIVE-CLiQ interface provides accurate position feedback, guaranteeing superior motion control and synchronization. This motor belongs to the SIMOTICS S High Inertia family, delivering optimized control behavior even under variable load conditions.

Overview

SIMOTICS S-1FK7 motors are compact, permanent-magnet synchronous motors that combine high torque density with precise motion performance. Their scalable options, including diverse encoder types and gearbox combinations, enable perfect adaptation across multiple industrial requirements. These motors integrate seamlessly with the SINAMICS S120/S220 drive systems, forming a complete servo solution that offers reliable speed and position control with minimal setup effort.

Heat is dissipated directly through the motor surface, allowing operation without external cooling and ensuring long-term stability. The robust mechanical structure and precise design deliver superior overload capability and long service life, meeting the evolving demands of modern automation systems.
