1FK7043-4CK71-1CG1 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

This is a premium high-performance synchronous motor designed for demanding industrial applications. This advanced motor delivers a rated power output of 1.3 kW with a rated torque of 3.5 Nm at a speed of 6000 rpm, ensuring consistent performance in high-speed and high-precision environments. Its compact and naturally cooled construction (IMB 5/IM V1/IM V3) allows for flexible installation in modern automation systems. The motor features an absolute encoder 24-bit + 12-bit multi-turn with DRIVE-CLiQ interface (AM24DQI), offering precise position and speed feedback. With a plain shaft, IP65 degree of protection, and rotatable power connector, this SIMOTICS S motor is engineered for durability, versatility, and easy integration into advanced drive systems.

Overview

The SIMOTICS S-1FK7 motor series represents a new generation of compact, permanent-magnet synchronous motors optimized for performance, efficiency, and reliability. These motors can be seamlessly integrated with SINAMICS S120 or S220 drive systems to form a powerful motion control solution. Depending on the application, the integrated encoder systems support precise speed and position control, ensuring accuracy even in dynamic load conditions. With an excellent overload capacity and natural convection cooling, the motor model operates efficiently without external cooling devices, reducing both energy consumption and maintenance complexity.

Design and Benefits

The SIMOTICS S-1FK7 family is available in three variants — Compact, High Dynamic, and High Inertia — each designed to match specific mechanical requirements. The Compact motor variant ensures space-saving installation thanks to its high power density, while the High Dynamic version delivers exceptionally fast acceleration through its low rotor moment of inertia. The High Inertia version provides robust control for variable loads, minimizing tuning efforts during commissioning. Overall, the motor offers precision motion, outstanding efficiency, and reliability for continuous industrial operation.
