Description
Product Description
The Siemens 1FT7085-7SF7X-1XXX is a SIMOTICS S-1FT7 High Dynamic synchronous servo motor engineered for demanding industrial motion control applications requiring high torque, exceptional positioning accuracy, and continuous-duty operation. Featuring forced ventilation cooling, this permanent magnet synchronous servo motor delivers 34 Nm standstill torque (100 K), 23 Nm rated torque, and 7.2 kW optimum output power at a 3000 RPM rated speed.
Designed for seamless integration with Siemens SINAMICS S120 drive systems, the 1FT7085-7SF7X-1XXX is ideal for CNC machine tools, industrial robotics, packaging equipment, printing machinery, material handling systems, and automated production lines. The configurable "X" and "1XXX" suffixes allow selection of encoder type, shaft design, holding brake, electrical connector, and mounting options while maintaining the same core motor performance.
