Description
Product Description
The Siemens 1FT7102-5AB71-1BH2 is a SIMOTICS S-1FT7 permanent magnet synchronous servo motor engineered for precision motion control and demanding industrial automation applications. Designed for seamless integration with Siemens SINAMICS S120 drive systems, this high-performance servo motor delivers excellent positioning accuracy, high torque density, rapid acceleration, and reliable continuous-duty operation. It is ideally suited for CNC machine tools, industrial robotics, packaging equipment, material handling systems, printing machinery, textile 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 motor design provides high efficiency, low rotor inertia, smooth operation, and excellent overload capability for precision motion control applications.
The 1FT7102-5AB71-1BH2 features natural cooling, IM B5 flange mounting, a plain shaft, IP65 protection, integrated Pt1000 temperature monitoring, and an absolute multi-turn encoder with DRIVE-CLiQ interface. The 1BH2 suffix identifies a specific encoder and electrical connection variant within the SIMOTICS S-1FT7 series while maintaining the same mechanical and electrical performance as other motors in the 1FT7102-5AB71 family.
