1FK7044-4CH71-1QB2 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S 1FK7044-4CH71-1QB2 is an exclusive high-performance synchronous motor designed to meet the exacting requirements of modern automation and machinery applications. Delivering a nominal power of 1.4 kW and a rated speed of 4500 rpm, this motor combines efficiency, reliability, and advanced features in a compact design. Its naturally cooled construction ensures stable operation without the need for additional cooling systems, while the robust IP65 protection rating guarantees safe performance even in challenging industrial environments. The flange IP67 and rotatable power connector allow flexible integration, making this motor ideal for diverse mechanical configurations.

Overview

The SIMOTICS S‑1FK7 series offers compact permanent-magnet synchronous motors suitable for a wide range of applications. These motors can be easily combined with the SINAMICS S120/S220 drive system to create a highly functional and powerful automation solution. Integrated encoders, including the AS20DQI Absolute Encoder with Drive-CLiQ interface, provide precise speed and position control tailored to the needs of any machine. With a high overload capability and durable design, these motors ensure reliable performance under demanding operational conditions.

Benefits and Applications

The 1FK7044-4CH71-1QB2 motor excels in both dynamic and high-inertia applications. Its compact design allows for space-saving installation, while offering extremely high power density. High-dynamic variants ensure rapid response with minimal rotor inertia, ideal for precise motion control. High-inertia versions provide robust closed-loop performance for machines with heavy or variable loads. Typical applications include machine tools, robots and handling systems, wood, glass, ceramics and stone working machinery, packaging, plastics, textile machines, printing machines, and auxiliary axes.

Its holding brake and shaft with fitted key (tolerance N) facilitate reliable torque transmission, while the IP65/67 degrees of protection and durable design ensure long-term operational stability in harsh industrial environments.
