Description
Product Description
The Siemens 1FT7102-5AB71-1BK0 is a SIMOTICS S-1FT7 permanent magnet synchronous servo motor designed for high-precision motion control in demanding industrial automation applications. Optimized for seamless integration with Siemens SINAMICS S120 drive systems, this high-performance servo motor delivers outstanding positioning accuracy, excellent torque density, rapid dynamic response, and reliable continuous-duty operation. It is ideal for CNC machine tools, industrial robotics, packaging machinery, material handling equipment, printing systems, and automated production lines.
The motor delivers 4.08 kW rated output power at 1,500 RPM, producing 26 Nm rated torque, 30 Nm stall torque (100 K), and up to 120 Nm peak torque. Its permanent magnet synchronous design ensures high efficiency, low rotor inertia, smooth operation, and excellent overload capability for precision motion control applications.
The 1FT7102-5AB71-1BK0 features natural cooling, IM B5 flange mounting, a plain shaft, IP65 protection, integrated Pt1000 temperature monitoring, and a high-resolution absolute encoder with DRIVE-CLiQ interface. The 1BK0 suffix identifies a specific encoder and connector configuration within the SIMOTICS S-1FT7 product family while maintaining identical mechanical and electrical performance characteristics. The exact encoder variant is determined by the complete Siemens MLFB ordering code.
