Siemens SIMOTICS S-1FT7 Synchronous Servo Motor About

The Siemens 1FT7084-5AF74-1NH3 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 naturally cooled permanent-magnet synchronous motor delivering 4.55 kW rated output power, 20 Nm rated torque, and a rated speed of 3,000 RPM. The motor uses an IM B5 mounting arrangement with a recessed flange for compact installation and includes a KTY temperature sensor for thermal monitoring. It is equipped with a rotatable power connector and an incremental SIN/COS encoder with 1 Vpp signal and 2,048 signals per revolution, with Drive-CLiQ interface. The motor has a plain shaft with a holding brake, accuracy tolerance N, and vibration severity grade A+R. Its IP64 protection rating makes it suitable for demanding industrial environments. The 1FT7084 family is engineered for precise speed, torque, and position control and is compatible with Siemens SINAMICS drive systems. It is well suited for CNC axes, machine tools, production automation, robotics, handling systems, and precision positioning applications requiring reliable dynamic performance and accurate feedback. The closely matching 1FT7084-5AF70-1NH3 configuration confirms the 4.55 kW, 3,000 RPM, 20 Nm specification and the same encoder, brake, and protection arrangement.
