Siemens SIMOTICS S-1FT7 Synchronous Servo Motor About

The Siemens 1FT7086-5AC74-1NA2 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 for precise speed, torque, and position control with Siemens SINAMICS drive systems. The motor uses an IM B5 mounting arrangement and is suitable for compact machine installations requiring high dynamic response and reliable continuous operation. The -5AC74 configuration identifies the motor's electrical and mechanical arrangement, while -1NA2 specifies the particular feedback, shaft, brake, and connection configuration. The 1FT7086 frame provides high power density and robust servo performance for demanding industrial applications. Typical applications include CNC machine tools, robotics, handling systems, production automation, packaging machinery, and precision positioning equipment. The permanent-magnet design provides efficient operation, rapid acceleration, and accurate motion control. For this exact MLFB, the rated power, rated torque, rated speed, encoder type, holding-brake specification, protection rating, dimensions, and weight should be verified against the Siemens-specific datasheet rather than inferred from another 1FT7086 variant.
