Siemens SIMOTICS S-1FT7 Synchronous Servo Motor About

The Siemens 1FT7084-5SC71-1BA1 is a SIMOTICS S-1FT7 synchronous servo motor designed for high-performance motion control, CNC machine tools, and industrial automation applications. It is a naturally cooled permanent-magnet synchronous motor with a rated torque of 27 Nm, rated speed of 2,000 RPM, and approximately 5.65 kW rated output power. The motor uses an IM B5 mounting arrangement with a conventional flange compatible with 1FT6/1FK7 mounting concepts and a rotatable power connector. The 1FT7 design provides high dynamic response, accurate speed and position control, and reliable continuous operation. This motor family is intended for integration with Siemens SINAMICS drive systems and is suitable for demanding servo applications requiring precise torque and positioning performance. Typical applications include CNC machine tools, robotics, handling systems, production automation, packaging machinery, and precision positioning equipment. The -5SC71-1BA1 configuration specifies the particular electrical, feedback, shaft, and connection arrangement. Exact encoder type, brake configuration, protection rating, dimensions, and weight should be verified against the MLFB-specific Siemens datasheet before procurement. The 1FT7084-5SC71 family is documented as a 27 Nm, 2,000 RPM SIMOTICS S-1FT7 motor.
