Siemens SIMOTICS S-1FT7 Synchronous Servo Motor About

The Siemens 1FT7084-5AF74-1NB1 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, providing approximately 4.55 kW rated output power, 20 Nm rated torque, and a rated speed of 3,000 RPM. The 1FT7084 family is a compact servo motor range intended for precise speed, torque, and position control in demanding automation systems. The motor is designed for integration with Siemens SINAMICS drive technology and offers high dynamic response and reliable continuous operation. The -5AF74 configuration identifies the electrical and mechanical motor variant, while the -1NB1 suffix defines the specific encoder, shaft, brake, and connection configuration. It is suitable for CNC axes, machine tools, robotics, material handling, packaging machinery, and precision positioning systems. The compact construction and permanent-magnet technology provide high power density and efficient servo performance. Exact encoder type, holding-brake specification, protection rating, dimensions, and weight should be verified against the Siemens MLFB-specific documentation before procurement. The 1FT7084-5AF7x family is listed as a 4.55 kW, 3,000 RPM, 20 Nm SIMOTICS S-1FT7 servo motor.
