Siemens SIMOTICS S-1FT7 Synchronous Servo Motor About

The Siemens 1FT7086-5AC71-1FA0 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 natural cooling, engineered for precise speed, torque, and position control. The 1FT7086 frame size provides a robust servo solution for demanding applications requiring high dynamic response and reliable continuous operation. The -5AC71 configuration identifies the motor's specific electrical and mechanical design, while -1FA0 specifies the corresponding feedback, shaft, brake, and connection configuration. The motor is intended for integration with Siemens SINAMICS drive systems and is suitable for CNC axes, machine tools, robotics, handling systems, production automation, packaging machinery, and precision positioning equipment. Its permanent-magnet technology provides high power density, efficient operation, and excellent servo controllability. The SIMOTICS S construction is designed for reliable industrial service and accurate repeatable movement. For this exact 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, as these specifications can differ between individual 1FT7086 variants.
