Description
Product Description
The Siemens 1FT7105-5SC7X-1XXX is a high-performance SIMOTICS S-1FT7 permanent magnet synchronous servo motor designed for demanding industrial motion control applications requiring high torque, precise positioning, and continuous-duty reliability. Engineered for seamless integration with Siemens SINAMICS S120 servo drive systems through the DRIVE-CLiQ interface, this forced-ventilated servo motor delivers exceptional dynamic response, excellent overload capability, and energy-efficient performance for CNC machine tools, rotary tables, robotics, packaging machinery, metal processing equipment, and automated production systems.
Operating at a rated speed of 2,000 RPM, the 1FT7105-5SC7X-1XXX provides an optimum output power of 11.7 kW, 56 Nm rated torque (100 K), and 65 Nm stall torque (100 K). The motor delivers up to 200 Nm maximum torque while supporting a maximum mechanical speed of 6,000 RPM, making it ideal for applications requiring high torque, rapid acceleration, and continuous industrial operation. Forced ventilation ensures efficient heat dissipation and reliable performance under heavy load conditions.
The 1FT7105-5SC7X-1XXX family is available in multiple MLFB variants with different encoder technologies, shaft configurations (plain shaft or fitted key), optional holding brakes, connector orientations, vibration grades, and protection classes. All variants feature IM B5 flange mounting, integrated temperature monitoring, and DRIVE-CLiQ digital communication for fast commissioning and advanced diagnostics.
