1FK7042-2AF71-1RA0 SIEMENS Exclusive SIMOTICS S-1FK7 Synchronous Motor Original Brand New

The SIEMENS 1FK7042-2AF71-1RA0 from the renowned SIMOTICS S-1FK7 series is a compact and efficient permanent-magnet synchronous motor engineered for high precision and reliability in industrial motion control systems. With a rated power of 0.82 kW and a torque of 3 Nm at 3000 rpm, this naturally cooled unit ensures consistent performance even under demanding continuous operation. Its design follows the IM B5 mounting standard and features a robust IP64 protection class, providing solid resistance against dust and splash water.

Equipped with an AM20DQI absolute encoder offering 20-bit + 12-bit multiturn resolution and integrated DRIVE-CLiQ interface, this model guarantees precise feedback for position and speed control. The rotatable power connector and keyed shaft add flexibility for various mechanical setups, while the absence of a holding brake simplifies integration in systems that prioritize smooth rotational movement. Built for long-term operation, this synchronous motor combines high torque density with low vibration for stable and silent performance.

Overview

The SIMOTICS S-1FK7 motors are compact, permanent-magnet synchronous units designed to deliver superior dynamic response in modern automation. They can be easily combined with SINAMICS S120 or S220 drives to form a highly versatile and intelligent drive system. Integrated encoders allow fine-tuned closed-loop control, ensuring that every motion is smooth, accurate, and energy-efficient.

These motors are naturally cooled through their surface, eliminating the need for additional cooling components. Their robust construction and optimized thermal design ensure a long service life even in continuous-duty environments. With multiple frame sizes, inertia options, and encoder configurations, the S-1FK7 series can be precisely tailored to diverse automation needs.

Applications and Advantages

The 1FK7042-2AF71-1RA0 is widely used in machine tools, robotics, packaging, textile, and printing machinery. Its exceptional dynamic behavior makes it suitable for rapid acceleration and deceleration cycles. The motor’s compact form factor enables space-saving installations, while its consistent torque output ensures accurate motion under variable loads. With high overload capacity and minimal maintenance requirements, it provides outstanding operational efficiency and reliability for industrial systems seeking optimized motion performance.
