Description
Product Description
The Siemens 1FT7105-5SF7X-1XXX is a high-performance SIMOTICS S-1FT7 permanent magnet synchronous servo motor designed for demanding industrial motion control applications requiring high torque, precision positioning, and continuous-duty reliability. Designed for seamless integration with Siemens SINAMICS S120 servo drive systems through the DRIVE-CLiQ interface, this forced-ventilated servo motor delivers exceptional dynamic response, high overload capability, and outstanding energy efficiency for CNC machine tools, industrial robots, rotary tables, packaging machinery, metal processing equipment, and automated production systems.
Operating at a rated speed of 3,000 RPM, the 1FT7105-5SF7X-1XXX delivers an optimum output power of 15.1 kW, 48 Nm rated torque (100 K), and 65 Nm stall torque (100 K). The motor can generate up to 200 Nm maximum torque while supporting a maximum mechanical speed of 6,000 RPM, providing excellent acceleration, high positioning accuracy, and reliable continuous operation under heavy-duty conditions.
The 1FT7105-5SF7X-1XXX family is available in numerous MLFB variants with multiple encoder systems, shaft configurations (plain shaft or fitted key), optional permanent-magnet holding brakes, connector orientations, vibration grades, and protection classes. All variants feature IM B5 flange mounting, integrated temperature monitoring, and DRIVE-CLiQ communication for simplified commissioning and advanced diagnostics.
