Siemens SIMOTICS S-1FT7 Synchronous Servo Motor About

The Siemens 1FT7086-5AC71-1CH5 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 to provide high dynamic response, precise positioning, and reliable continuous operation. The 1FT7086 frame size offers a robust solution for demanding servo applications requiring high torque and accurate motion control. The -5AC71 configuration identifies the motor's specific electrical and mechanical arrangement, while -1CH5 defines the corresponding 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, material handling, production automation, packaging machinery, and precision positioning equipment. Its permanent-magnet technology provides high power density and efficient servo operation, while the SIMOTICS S construction supports accurate speed, torque, and position regulation. 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 rather than inferred from another 1FT7086 variant.
