Siemens SIMOTICS S-1FT7 Synchronous Servo Motor About

The Siemens 1FT7086-5WC71-1LG5 is a SIMOTICS S-1FT7 synchronous servo motor designed for high-performance motion control, CNC machine tools, robotics, and industrial automation applications. It is a permanent-magnet synchronous motor with water cooling, engineered for efficient heat dissipation, high power density, precise positioning, and reliable continuous operation under demanding loads. The 1FT7086 frame size provides a robust servo solution for applications requiring high dynamic response and accurate speed and torque control. The -5WC71 configuration identifies the motor's specific electrical, mechanical, and water-cooling arrangement, while -1LG5 specifies the particular feedback, shaft, brake, and connection configuration. The motor is designed for integration with Siemens SINAMICS drive systems and is suitable for CNC axes, machine tools, robotics, handling equipment, production automation, packaging machinery, and precision positioning systems. Water cooling makes this configuration particularly suitable where efficient thermal management and compact installation are important. For the exact 1FT7086-5WC71-1LG5 MLFB, the rated power, rated torque, rated speed, encoder type, holding-brake specification, protection rating, dimensions, and weight should be verified from the Siemens-specific datasheet rather than inferred from another 1FT7086 variant.
