Siemens 1FT6105-8SF71-4UB0 Synchronous Servo Motor for 1FT6 Series

The Siemens 1FT6105-8SF71-4UB0 (1FT6105-8SF71-4UB0) is a permanent-magnet synchronous AC servo motor engineered for precise velocity, positioning, and torque control in demanding motion applications. Operating within the Siemens 1FT6 motor family, this unit is engineered for seamless integration with compatible drive systems such as Siemens SIMODRIVE 611 and SINAMICS converters. It delivers dynamic response and reliable performance across computer numerical control machinery, machine tool feed axes, automated production lines, robotics, and industrial material handling systems. Built for dependable operation in rigorous factory environments, this compact motor features a robust housing that provides essential environmental resistance and effective thermal dissipation during continuous duty cycles. With a net weight of approximately 10 kg, it offers a well-balanced power-to-weight ratio for automated axis drive assemblies. Routine replacement or preventative maintenance with this exact model restores factory-calibrated dynamic accuracy, operational stability, and minimal downtime across critical production machinery. When servicing or replacing drive components, verify existing motor specifications and mechanical mounting arrangements against system documentation to ensure proper alignment and system compatibility.
