1FK7042-2AC71-1PA1 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S 1FK7042-2AC71-1PA1 is a high-precision synchronous servo motor engineered for efficiency, performance, and long-term durability. Designed for natural cooling, this compact and robust motor delivers a continuous torque of 3 Nm and a nominal speed of 2000 rpm. With a rated power of 0.59 kW at a 600V DC link voltage, it ensures stable operation and smooth performance even under high load conditions. The design follows the IMB5 mounting style (IM V1, IM V3), featuring a rotatable power connector and a two-pole resolver with DRIVE-CLiQ interface for precise communication with SINAMICS drive systems. Built to IP65 protection standards, it guarantees superior resistance to dust and moisture, making it ideal for demanding industrial environments.

Overview

The SIMOTICS S-1FK7 series represents a family of permanent-magnet synchronous motors developed for applications that demand compact design, high power density, and dynamic control. With a wide selection of mechanical configurations, feedback options, and compatible gearboxes, these motors provide maximum flexibility for integration into various automation setups. When paired with SINAMICS S120 or S220 drive systems, the result is a highly coordinated and energy-efficient system that delivers precision motion control across complex production lines. Each motor is designed for operation without external cooling, efficiently dissipating heat through its housing, while maintaining excellent overload capacity for continuous, reliable performance.

Benefits

SIMOTICS S-1FK7 Compact motors offer a space-saving structure and a high power-to-size ratio, making them ideal for installations where footprint is limited. The High Dynamic variant provides exceptionally fast response characteristics due to its low rotor inertia, while the High Inertia version enhances control stability under varying load conditions. Together, these configurations ensure optimal flexibility, low commissioning effort, and smooth operation across diverse automation systems.

Applications

This motor series is perfectly suited for high-precision industrial tasks, including CNC machine tools, robotics, and automated handling systems. It is also widely used in packaging, printing, woodworking, and textile machinery, where reliability and repeatable accuracy are essential. With its robust design and Siemens engineering excellence, the 1FK7042-2AC71-1PA1 stands as a dependable component for advanced motion control and energy-efficient automation.
