Siemens SIMOTICS S-1FT7 Synchronous Servo Motor About

The Siemens 1FT7086-5AC74-1MH4 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 from the 1FT7 series, engineered for precise speed, torque, and position control with Siemens SINAMICS drive systems. The motor uses a naturally cooled construction and an IM B5 mounting arrangement, making it suitable for compact machine installations. The -5AC74 configuration identifies the motor's electrical and mechanical design, while -1MH4 specifies the particular feedback, shaft, brake, and connection arrangement. The motor is suitable for demanding applications requiring high dynamic response, accurate positioning, and reliable continuous operation, including CNC machine tools, robotics, handling equipment, production automation, packaging machinery, and precision positioning systems. Its permanent-magnet technology provides high power density and efficient servo operation. For this exact 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 1FT7086 variant.
