Siemens SIMOTICS S-1FT7 Synchronous Servo Motor About
The Siemens 1FT7087-7AF71-1MH1 is a SIMOTICS S-1FT7 synchronous servo motor designed for high-performance motion control, CNC machine tools, robotics, and demanding industrial automation applications. It uses permanent-magnet synchronous motor technology for precise speed, torque, and position control and is designed for integration with Siemens SINAMICS drive systems. The 1FT7087 frame size provides a robust servo solution with high power density, rapid dynamic response, and reliable continuous-duty performance. The -7AF71 configuration identifies the motor's electrical, mechanical, and cooling arrangement, while -1MH1 specifies the particular feedback, shaft, brake, and connection configuration. The motor is suitable for CNC axes, machine tools, robotics, handling equipment, production automation, packaging machinery, and precision positioning systems requiring accurate and repeatable motion. Its permanent-magnet construction supports efficient servo operation and excellent dynamic response. For the exact 1FT7087-7AF71-1MH1 MLFB, the rated power, rated torque, rated speed, encoder type, holding-brake specification, protection rating, dimensions, and weight should be verified from the Siemens-specific datasheet rather than inferred from another 1FT7087 variant.
