Description
Product Description
The Siemens 1FT7105-5AF7X-1XXX is a high-performance SIMOTICS S-1FT7 permanent magnet synchronous servo motor engineered for demanding industrial motion control applications requiring high continuous torque, exceptional positioning accuracy, and superior dynamic response. Designed for seamless integration with Siemens SINAMICS S120 servo drive systems via the DRIVE-CLiQ interface, this naturally cooled servo motor delivers outstanding efficiency and reliability for CNC machine tools, industrial robotics, packaging machinery, printing equipment, material handling systems, and automated production lines.
Operating at a rated speed of 3,000 RPM, the 1FT7105-5AF7X-1XXX delivers 8.80 kW rated output power, 28 Nm rated torque (100 K), and 50 Nm stall torque (100 K). The motor is capable of producing up to 200 Nm maximum torque while supporting a maximum mechanical speed of 6,000 RPM, providing excellent overload capability, rapid acceleration, and highly accurate motion control. The permanent magnet rotor design ensures high torque density, low inertia, and high operating efficiency of up to 94%.
The 1FT7105-5AF7X-1XXX product family includes numerous MLFB variants featuring different encoder technologies, shaft configurations (plain shaft or fitted key), optional holding brakes, connector orientations, vibration grades, and protection ratings. All variants feature natural cooling, IM B5 flange mounting, integrated temperature monitoring, and DRIVE-CLiQ communication. The exact motor configuration depends on the complete Siemens MLFB ordering code.
