Designed for natural cooling and equipped with a rotatable power connector, this motor offers flexible installation and easy integration into existing machine architectures. The IP64-rated construction ensures excellent protection against dust and splashing water, extending operational lifespan in industrial environments.

Overview

The SIMOTICS S-1FK7 family represents the next generation of compact, permanent-magnet synchronous motors optimized for flexible and high-precision motion tasks. The 1FK7044-4CF71-1UB0 model combines robust performance with compact dimensions, making it suitable for machine tools, automation systems, and robotics. It supports high dynamic response due to a low rotor moment of inertia, ensuring quick acceleration and precise positioning. The integrated encoder system enables accurate speed and position feedback, while compatibility with SINAMICS S120/S220 drives creates a powerful motion control ecosystem. These motors are designed for maintenance-free operation, dissipating heat effectively through the housing without external cooling. Their wide range of variants allows seamless adaptation to diverse industrial processes, supporting consistent output even in continuous operation.

Design and Application

The motor includes a resolver multi-pole with DRIVE-CLiQ interface, a shaft with fitted key (tolerance N), and a holding brake for secure operational stability. The rugged mechanical design and natural convection cooling make it ideal for integration into machinery used in packaging, printing, and material handling industries. Its versatility also extends to applications in robotics, woodworking, glass processing, textiles, and auxiliary axes. Every component reflects Siemens’ precision engineering—ensuring superior dynamic response, reduced commissioning time, and extended service life in demanding industrial environments.
