Siemens SIMOTICS S-1FT7 Synchronous Servo Motor About

The Siemens 1FT7105-5WC71-1NL5 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 1FT7105 frame size provides a robust servo solution with high power density, rapid dynamic response, and reliable continuous-duty performance. The -5WC71 configuration identifies the motor's electrical, mechanical, and water-cooling arrangement, while -1NL5 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 water-cooled construction supports efficient thermal management and high power density, making it suitable for applications with demanding continuous loads. For the exact 1FT7105-5WC71-1NL5 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 1FT7105 variant.
