Product Introduction: The SIEMENS 1FK6084-6AZ21-9ZZ9-Z-S29 is a component of the SIMOTICS S 1FK6 family of synchronous servo motors. Designed for use with SINAMICS drive systems, this permanent magnet motor offers high power density, excellent dynamic response, and precise positioning capabilities for demanding automation applications such as machine tools, packaging machines, and handling systems.
The SIMOTICS S 1FK6 series represents Siemens' compact and versatile solution for sophisticated motion control tasks. The 1FK6084-6AZ21-9ZZ9-Z-S29 model embodies the series' core philosophy: delivering maximum performance in a minimal footprint. As a permanently excited synchronous motor, it uses high-energy permanent magnets embedded in the rotor to generate torque. This design eliminates rotor copper losses, resulting in high efficiency, excellent torque-to-inertia ratio, and superior dynamic performance compared to asynchronous motors. The motor is engineered for seamless integration into the Totally Integrated Automation (TIA) portal, ensuring straightforward configuration, commissioning, and diagnostics when paired with compatible Siemens drives and controls.
The motor's compact design houses high-grade magnets and optimized windings, yielding a high power density. Its low rotor inertia allows for extremely fast acceleration and deceleration, which is critical for reducing cycle times in pick-and-place, indexing, and contouring applications. This enables machinery to operate at higher speeds and throughput without sacrificing precision.
A key feature of this specific model is its integrated encoder, indicated by the "Z" designations in the order code. It is typically equipped with a high-resolution sine/cosine encoder (EnDat or similar) that provides precise feedback on rotor position and speed. This feedback is essential for the drive to perform accurate closed-loop control, enabling precise positioning, smooth rotation at low speeds, and reliable synchronization in multi-axis systems.
Built for the industrial environment, the motor features a rugged housing that provides high stiffness and effective heat dissipation. The protection rating (e.g., IP64 or IP65 as per model) guards against dust and water jets. An efficient cooling design, often through natural convection or an optional external fan, ensures sustained performance even under continuous duty cycles with high overload capability, maximizing operational uptime.
