Description
Product Description
The Siemens 1FT7086-5AF7X-1XXX is a high-performance SIMOTICS S-1FT7 permanent magnet synchronous servo motor designed for demanding industrial motion control applications requiring high torque, exceptional positioning accuracy, and superior dynamic response. Engineered for seamless integration with Siemens SINAMICS S120 servo drive systems through DRIVE-CLiQ, this motor delivers reliable, efficient operation for CNC machine tools, industrial robotics, packaging machinery, printing equipment, semiconductor manufacturing, material handling systems, and other advanced automation applications.
Operating at a rated speed of 3,000 RPM, the 1FT7086-5AF7X-1XXX provides 5.65 kW rated output power, 18.0 Nm rated torque, and 28 Nm stall torque (100 K). It is capable of delivering up to 120 Nm maximum torque while supporting a maximum mechanical speed of 8,000 RPM, ensuring excellent overload capability, rapid acceleration, and precise servo control. The permanent magnet rotor design offers high torque density, low inertia, and outstanding energy efficiency.
The 1FT7086-5AF7X-1XXX product family includes multiple MLFB variants with different encoder technologies, shaft versions (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 configuration depends on the complete Siemens MLFB ordering code.
