Description
Product Description
The Siemens 1FT7102-5AB71-1BG4 is a SIMOTICS S-1FT7 permanent magnet synchronous servo motor engineered for demanding motion control and industrial automation applications. Designed for seamless integration with Siemens SINAMICS S120 drive systems, this high-performance servo motor delivers outstanding positioning accuracy, excellent torque density, rapid acceleration, and dependable continuous-duty operation. It is ideal for CNC machine tools, robotics, packaging equipment, material handling systems, printing machinery, and automated manufacturing lines.
Operating at a rated speed of 1,500 RPM, the motor provides 4.08 kW rated output power, 26 Nm rated torque, 30 Nm stall torque (100 K), and 120 Nm maximum torque. Its permanent magnet synchronous design ensures high efficiency, low rotor inertia, excellent overload capability, and smooth, accurate motion control for precision industrial applications.
The 1FT7102-5AB71-1BG4 features natural cooling, IM B5 flange mounting, IP65 protection, a plain shaft, integrated Pt1000 temperature monitoring, and a 24-bit absolute multi-turn encoder with DRIVE-CLiQ interface (AM24DQI). The 1BG4 suffix identifies a specific encoder and connector configuration within the SIMOTICS S-1FT7 series while maintaining the same core mechanical and electrical performance.
