1FK7043-4CK71-1BG0 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S  is a high-performance synchronous servo motor designed for precision, durability, and energy efficiency. With a rated power of 1.3 kW and a torque of 3.5 Nm, it provides excellent acceleration and consistent torque output across a broad speed range of up to 6000 rpm.

This motor features natural cooling, a rotatable power connector, and a robust flange-mounted design (IMB 5, IM V1, IM V3) for flexible installation in industrial systems. The plain shaft design with a 24-bit single-turn absolute encoder (AS24DQI) using DRIVE-CLiQ interface ensures high-resolution feedback for accurate positioning and control. Built with IP64 protection, the motor guarantees reliable performance even in demanding environments.

Overview

The SIMOTICS S-1FK7 series from SIEMENS represents a new generation of compact, permanent-magnet synchronous motors known for their versatility and integration with the SINAMICS S120 and S220 drive systems. This model supports precise motion control and outstanding power density, enabling manufacturers to achieve optimal performance with smaller installation space. The integrated encoder systems allow for smooth speed and position feedback, ensuring precise motion control in dynamic applications. Designed for operation without external cooling, the heat generated is efficiently dissipated through the motor housing, supporting longer operational life and reduced maintenance needs.

Design and Benefits

The 1FK7043-4CK71-1BG0 motor combines compact design with robust construction, making it suitable for a wide range of industrial applications. Its high dynamic response results from the low rotor inertia, while the optional configurations for various load conditions make it ideal for automation tasks. The SIMOTICS S-1FK7 family includes Compact, High Dynamic, and High Inertia types—each optimized for different performance requirements. These motors provide exceptional efficiency, stability, and precision, reducing commissioning time and offering superior closed-loop control characteristics.

Applications include: CNC machine tools, robotics and handling systems, packaging and textile machines, glass and stone processing, printing equipment, and auxiliary axis control in multi-axis setups.
