Description
Product Description
The Siemens 1FT7084-5AF7X-1XXX is a premium SIMOTICS S-1FT7 permanent magnet synchronous servo motor engineered for high-performance industrial motion control applications requiring exceptional torque, precision, and dynamic response. Designed for seamless integration with Siemens SINAMICS S120 servo drive systems via DRIVE-CLiQ, this motor delivers reliable positioning accuracy, high overload capability, and excellent energy efficiency for CNC machine tools, industrial robotics, packaging equipment, material handling systems, printing machinery, and automated manufacturing lines.
Operating at a rated speed of 3,000 RPM, the 1FT7084-5AF7X-1XXX delivers 4.55 kW rated output power, 14.5 Nm rated torque, and 20 Nm stall torque (100 K). The motor can generate up to 81 Nm maximum torque while supporting a maximum mechanical speed of 8,000 RPM, providing rapid acceleration, outstanding overload performance, and highly accurate servo control. Its permanent magnet rotor offers high torque density, low inertia, and superior dynamic characteristics.
The 1FT7084-5AF7X-1XXX family includes numerous MLFB variants with different encoder systems, shaft configurations (plain shaft or fitted key), optional holding brakes, connector orientations, vibration grades, and protection classes. All variants feature natural cooling, IM B5 flange mounting, integrated temperature monitoring, and DRIVE-CLiQ communication for simplified commissioning and diagnostics. The exact motor configuration is determined by the complete Siemens MLFB ordering code.
