Description
Product Description
The Siemens 1FT7102-5AF7X-1XXX is a premium SIMOTICS S-1FT7 permanent magnet synchronous servo motor designed for demanding motion control applications requiring high continuous torque, outstanding positioning accuracy, and rapid dynamic response. Optimized for operation with Siemens SINAMICS S120 servo drive systems, this naturally cooled motor is ideal for CNC machine tools, industrial robotics, packaging equipment, printing presses, material handling systems, and high-performance automation applications. It combines high torque density, low rotor inertia, and advanced encoder technology to deliver reliable and efficient motion control.
Operating at a rated speed of 3,000 RPM, the 1FT7102-5AF7X-1XXX delivers 6.28 kW rated output power, 20.0 Nm rated torque, and 30 Nm stall torque (100 K). The motor is capable of producing up to 120 Nm maximum torque while supporting maximum mechanical speeds up to 8,000 RPM, making it ideal for applications requiring high overload capacity, rapid acceleration, and precise positioning. Its permanent magnet rotor ensures excellent efficiency and smooth servo performance.
The 1FT7102-5AF7X-1XXX family includes numerous MLFB variants with different encoder systems, shaft versions (plain shaft or keyed shaft), optional holding brakes, connector orientations, vibration grades, and protection ratings. All variants feature natural cooling, IM B5 flange mounting, DRIVE-CLiQ communication, and integrated motor temperature monitoring. The exact configuration depends on the complete Siemens MLFB ordering code.
