Siemens SIMOTICS S-1FT7 Synchronous Servo Motor About

The Siemens 1FT7086-5AF71-1BD1 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 in demanding servo applications. The 1FT7086 frame size provides a robust and compact solution with high power density and rapid dynamic response. The -5AF71 configuration identifies the motor's electrical, mechanical, and cooling arrangement, while -1BD1 specifies the particular feedback, shaft, brake, and connection configuration. The motor is designed for integration with Siemens SINAMICS drive systems and is suitable for CNC axes, machine tools, robotics, handling equipment, production automation, packaging machinery, and precision positioning systems. Its permanent-magnet design provides efficient servo operation and accurate repeatable movement. For the exact 1FT7086-5AF71-1BD1 MLFB, the rated power, rated torque, rated speed, encoder type, holding-brake specification, protection rating, dimensions, and weight should be confirmed from the Siemens-specific datasheet, rather than inferred from another 1FT7086 variant.
