Description
Product Description
The Siemens 1FT7085-7WF7X-1XXX is a SIMOTICS S-1FT7 High Dynamic synchronous servo motor engineered for demanding industrial motion control applications requiring high torque, precision, and continuous-duty performance. Featuring water cooling, this permanent magnet synchronous servo motor delivers 43 Nm standstill torque (100 K), 38 Nm rated torque, and 11.9 kW optimum output power at a 3000 RPM rated speed. Its high torque density, efficient thermal management, and exceptional dynamic response make it ideal for CNC machine tools, robotics, packaging machinery, printing systems, and material handling equipment.
Designed for seamless integration with Siemens SINAMICS S120 drive systems, the 1FT7085-7WF7X-1XXX provides accurate positioning, rapid acceleration, and reliable long-term operation in demanding industrial environments. The configurable "X" in 7WF7X and the "1XXX" suffix represent factory-selectable options such as encoder type, shaft configuration, holding brake, connector orientation, and mounting arrangement while maintaining the same core motor performance.
