Siemens SIMOTICS S-1FT7 Synchronous Servo Motor About

The Siemens 1FT7084-5AF71-4FE1 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 motor belongs to the 1FT7084 frame size and uses an IM B5 mounting arrangement, making it suitable for integration into compact machine-tool and automation assemblies. The -5AF71 configuration identifies the motor's electrical and mechanical characteristics, while the -4FE1 suffix specifies the particular feedback and connection configuration. The motor is compatible with Siemens SINAMICS drive systems and is intended for applications requiring accurate speed, torque, and position regulation. Its robust construction and servo-oriented design make it suitable for CNC axes, machine handling, packaging equipment, production lines, and precision automation. For this exact MLFB, the rated power, torque, speed, encoder type, holding-brake configuration, dimensions, and weight should be verified against the Siemens-specific datasheet, as these values can vary between 1FT7084 variants.
