Description
Product Description
The Siemens 1FT7108-5SC7X-1XXX is a premium SIMOTICS S-1FT7 permanent magnet synchronous servo motor engineered for high-performance industrial motion control applications that demand exceptional torque, precision, and continuous-duty reliability. Designed for seamless integration with Siemens SINAMICS S120 servo drive systems via the DRIVE-CLiQ interface, this forced-ventilated servo motor delivers superior dynamic response, excellent overload capability, and high energy efficiency for CNC machine tools, industrial robotics, rotary tables, metal processing machinery, packaging equipment, and automated production systems.
Operating at a rated speed of 2,000 RPM, the 1FT7108-5SC7X-1XXX provides an optimum output power of 15.3 kW, 73 Nm rated torque (100 K), and 91 Nm stall torque (100 K). The motor is capable of producing up to 280 Nm maximum torque while supporting a maximum mechanical speed of 6,000 RPM, making it ideal for demanding applications requiring rapid acceleration, precise positioning, and continuous high-load operation. Forced ventilation ensures efficient cooling and dependable thermal performance.
The 1FT7108-5SC7X-1XXX family is available in numerous MLFB configurations with multiple encoder systems, shaft options (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.
