Siemens SIMOTICS S-1FT7 Synchronous Servo Motor About

The Siemens 1FT7084-5SH71-1BB0 is a SIMOTICS S-1FT7 synchronous servo motor designed for high-performance motion control, CNC machine tools, high-speed spindles, and industrial automation. It is a permanent-magnet synchronous motor with forced ventilation, providing a rated torque of 27 Nm at a rated speed of 4,500 RPM and approximately 12.7 kW rated output power. The motor is engineered for high dynamic response, precise speed and position control, and reliable operation in demanding industrial environments. It uses an IM B5 mounting arrangement and is intended for integration with Siemens SINAMICS drive systems. The 1FT7084-5SH71 family is specifically associated with 27 Nm and 4,500 RPM performance. The motor is suitable for CNC spindle systems, machine tools, robotics, material handling, production automation, and precision positioning applications. The exact encoder type, holding-brake configuration, protection rating, dimensions, and weight depend on the final MLFB suffix and should be verified against the Siemens-specific datasheet before procurement. The -1BB0 configuration identifies the specific feedback, shaft, brake, and connection arrangement of this motor variant.
