1FK7043-4CF21-1CA0 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New
The SIEMENS SIMOTICS S 1FK7043-4CF21-1CA0 is a premium high-performance synchronous motor built for precision motion and dynamic industrial automation. This exclusive model delivers a rated power of 0.94 kW and torque of 3.3 Nm at 3000 rpm, providing exceptional control accuracy and reliability for demanding applications. Its naturally cooled design with IP64 protection ensures long-term durability even in harsh production environments. Featuring a rotatable power connector and an absolute 24-bit + 12-bit multiturn encoder (AM24DQI) with DRIVE-CLiQ interface, this motor guarantees precise position feedback and smooth synchronization with SINAMICS S120 or S220 drive systems.
Overview
The SIMOTICS S-1FK7 series represents a compact range of permanent-magnet synchronous motors designed for the latest generation of machine automation. Each motor combines high torque density with minimal installation space, enabling energy-efficient operation and flexible integration into modern systems. The 1FK7043-4CF21-1CA0 variant supports universal configuration options including different encoders, shaft designs, and gear units to match specific performance requirements. Its compact frame size IMB 5 (IM V1, IM V3) and precise construction make it suitable for vertical or horizontal installation without additional cooling equipment. By dissipating heat through its metal surface, this motor achieves consistent performance and superior thermal management.
Design and Application
Built with advanced rotor technology, the SIMOTICS S 1FK7 High Dynamic type ensures quick acceleration and outstanding motion response. The low rotor moment of inertia enables excellent servo accuracy, while its closed-loop control system supports consistent torque stability across variable loads. The motor’s shaft with fitted key (N tolerance) allows direct mechanical coupling and easy maintenance. Without a holding brake, it is ideal for axes that require continuous or repetitive movement with high responsiveness.
Typical applications include machine tools, robotic handling, packaging and printing equipment, wood and stone processing, and textile machinery. When paired with SINAMICS drives, the 1FK7 motors form a powerful system solution for automated production lines, combining reliability, performance, and compact design to meet evolving industrial requirements.
