1FK7044-4CH71-1QB0 SIEMENS Exclusive High Dynamic Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S 1FK7044-4CH71-1QB0 is a premium-grade synchronous servo motor engineered for precision, performance, and durability in industrial automation. Delivering a rated power of 1.4 kW and a rated torque of 4.5 Nm at 4500 rpm, this model combines compact dimensions with high dynamic response. Its naturally cooled design and IP64 protection make it ideal for demanding applications across production environments. Equipped with an absolute encoder singleturn 20-bit with DRIVE-CLiQ interface (AS20DQI) and a fitted key shaft, the motor ensures accurate speed and position feedback. The rotatable power connector and integrated holding brake add convenience and safety to the installation and operation process, offering flexible integration into existing motion control systems.

Overview

The SIMOTICS S-1FK7 motor series from Siemens represents a new generation of compact, permanent-magnet synchronous motors designed to meet the growing needs of high-performance machinery. Each model can be tailored through a wide range of encoder systems, gearbox options, and frame sizes to match specific applications. The motors deliver exceptional efficiency and stability even under high loads, making them suitable for continuous-duty operation. When paired with SINAMICS S120 or S220 drive systems, the 1FK7 series provides a fully integrated drive solution with smooth torque delivery, precise motion control, and superior system diagnostics.

Design and Benefits

The 1FK7044-4CH71-1QB0 features a robust and compact construction optimized for energy efficiency and easy mounting. Its low rotor moment of inertia delivers high dynamic performance, allowing quick acceleration and deceleration for precise machine movements. The natural cooling system eliminates the need for external fans, reducing maintenance while maintaining optimal operating temperature. With flexible flange mounting (IMB5, IMV1, IMV3) and durable materials, this model ensures long operational life and reliability in harsh environments.

• High power density for compact machine design
• Flexible configuration options for versatile applications
