1FK7043-4CK71-1QB2 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S 1FK7043-4CK71-1QB2 is a premium-grade synchronous motor engineered for exceptional precision, efficiency, and durability in industrial automation environments. With a rated power of 1.3 kW and a torque of 3.5 Nm at 6000 rpm, this high-dynamic model ensures reliable performance across a wide range of motion control applications. The motor’s naturally cooled design and IMB 5 (IM V1, IM V3) mounting configuration provide optimal heat dissipation and mechanical stability. Featuring an absolute single-turn 20-bit encoder with DRIVE-CLiQ interface and integrated holding brake, the 1FK7043-4CK71-1QB2 guarantees accurate feedback and smooth operation in synchronized systems.

Overview

The SIMOTICS S-1FK7 series from Siemens represents a new generation of compact, permanent-magnet synchronous motors. Designed for maximum flexibility, these motors can be seamlessly combined with SINAMICS S120 or S220 drive systems to deliver a complete motion control solution. Available in various configurations and encoder types, the series supports precise speed and position control for complex machine automation. The motors operate without external cooling, relying on surface heat dissipation to maintain optimal temperature, while offering superior overload capacity for demanding cycles. Each model in the range is built for efficiency, high responsiveness, and adaptability to different industrial environments.

Design and Benefits

The 1FK7043-4CK71-1QB2 is part of the SIMOTICS S-1FK7 High Dynamic line, known for its outstanding acceleration due to its low rotor inertia. It ensures rapid response times and high control precision, making it ideal for motion-intensive applications such as robotics, packaging, and CNC machining. The robust design, combined with IP65/IP67 protection, guarantees long service life even in challenging industrial conditions. This motor is also engineered for easy installation and integration into modular systems. Its compact dimensions allow space-saving assembly without compromising performance, and its flexible encoder options provide tailored control for various industrial setups.
