Description
Product Description
The Siemens 1FT7102-5AB71-1BG1 is a SIMOTICS S-1FT7 permanent magnet synchronous servo motor engineered for high-precision motion control and demanding industrial automation applications. Designed for seamless integration with Siemens SINAMICS S120 drive systems, this servo motor delivers outstanding positioning accuracy, high torque density, rapid dynamic response, and reliable continuous-duty performance. It is ideal for CNC machining centers, industrial robotics, packaging equipment, material handling systems, printing machinery, and automated production lines.
Operating at a rated speed of 1,500 RPM, the motor delivers 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 provides high efficiency, low rotor inertia, excellent overload capability, and smooth, precise motion control for demanding servo applications.
The 1FT7102-5AB71-1BG1 features natural cooling, IM B5 flange mounting, a plain shaft, IP65 protection, integrated temperature monitoring, and a 24-bit absolute single-turn encoder with DRIVE-CLiQ interface (AS24DQI) for high-accuracy position and speed feedback. The 1BG1 suffix identifies a specific encoder and electrical interface configuration while maintaining the same mechanical and electrical performance characteristics as other motors in the 1FT7102-5AB71 series.
