Description
Product Description
The Siemens 1FT7102-5AB71-1BG3 is a SIMOTICS S-1FT7 permanent magnet synchronous servo motor designed for high-precision motion control and demanding industrial automation applications. Optimized for operation with Siemens SINAMICS S120 drive systems, this motor delivers exceptional positioning accuracy, high torque density, fast dynamic response, and reliable continuous-duty performance. It is ideally suited for CNC machine tools, industrial robotics, packaging machinery, material handling systems, printing equipment, and automated manufacturing 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 up to 120 Nm maximum torque. Its permanent magnet synchronous design provides high efficiency, low rotor inertia, and excellent overload capability for precise speed and position control in demanding servo applications.
The 1FT7102-5AB71-1BG3 features natural cooling, IM B5 flange mounting, IP65 protection, a plain shaft, integrated Pt1000 temperature monitoring, and an absolute multi-turn 24-bit encoder with DRIVE-CLiQ interface (AM24DQI) for highly accurate motion feedback. The 1BG3 suffix denotes a specific encoder and connector configuration within the SIMOTICS S-1FT7 product family while maintaining the same core motor performance.
