1FK7042-2AF71-1PH1 SIEMENS Exclusive SIMOTICS S-1FK7 Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S-1FK7 synchronous motor with part number 1FK7042-2AF71-1PH1 is a premium-class servo motor engineered for precision, reliability, and long-term performance in demanding automation environments. Designed with advanced permanent-magnet technology, this motor delivers an output power of 0.82 kW at a nominal speed of 3000 rpm, ensuring smooth operation and accurate torque delivery across industrial applications. With a rated torque of 3 Nm (100K) and a 600 V DC supply, it guarantees dependable performance under continuous load conditions. The robust IMB 5 (IM V1, IM V3) flange construction and naturally cooled design make it suitable for continuous operation even in compact spaces.

Overview

The SIMOTICS S-1FK7 motor series represents Siemens’ next-generation solution for high-precision motion control. These compact, permanent-magnet synchronous motors are designed for seamless integration with SINAMICS S120 or S220 drive systems, forming a powerful, flexible automation platform. Each motor is equipped with a DRIVE-CLiQ interface and an integrated resolver for precise speed and position feedback, ensuring optimal synchronization and control accuracy. Designed for operation without external cooling, the motor efficiently dissipates heat through its enclosure, contributing to long service life and reduced maintenance.

The S-1FK7 series covers Compact, High Dynamic, and High Inertia variants, enabling tailored performance for diverse applications. Compact motors provide space-saving installation with high power density; High Dynamic models deliver fast acceleration due to low rotor inertia; and High Inertia versions ensure stable closed-loop control in systems with variable load inertia. Each variant upholds Siemens’ standards of precision, durability, and adaptability.

Applications

This motor is ideal for machine tools, robotics, packaging, printing, plastics, textile, and material-processing systems. Its versatility extends to auxiliary and positioning axes where exact speed and torque are essential. The 1FK7042-2AF71-1PH1 ensures minimal vibration, excellent control accuracy, and superior performance consistency, making it an outstanding choice for automated industrial environments seeking maximum productivity and efficiency.
