Description
Product Description
The Siemens 1FT7084-5SF7X-1XXX is a high-performance SIMOTICS S-1FT7 permanent magnet synchronous servo motor engineered for precision motion control and demanding industrial automation applications. Designed for seamless integration with Siemens SINAMICS S120 servo drive systems through the DRIVE-CLiQ interface, this forced-ventilated servo motor delivers high torque density, rapid dynamic response, and exceptional positioning accuracy for CNC machine tools, industrial robotics, rotary tables, packaging equipment, and automated production systems.
Operating at a rated speed of 3,000 RPM, the 1FT7084-5SF7X-1XXX delivers an optimum output power of 7.20 kW, 23 Nm rated torque (100 K), and 27 Nm stall torque (100 K). The motor is capable of producing up to 81 Nm maximum torque while supporting a maximum mechanical speed of 8,000 RPM, making it ideal for applications requiring high-speed operation, rapid acceleration, and continuous-duty performance.
The 1FT7084-5SF7X-1XXX product family includes numerous MLFB variants with multiple encoder options, shaft configurations (plain shaft or fitted key), optional permanent-magnet holding brakes, connector orientations, vibration grades, and IP protection classes. All variants feature IM B5 flange mounting, integrated motor temperature monitoring, and DRIVE-CLiQ communication for simplified commissioning and diagnostics.
