Description
Product Description
The Siemens 1FT7102-5AB71-1BL1 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 exceptional positioning accuracy, high torque density, rapid acceleration, and reliable continuous-duty operation. It is ideally suited for CNC machine tools, industrial robotics, packaging machinery, material handling systems, printing equipment, semiconductor manufacturing, and automated production 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 up to 120 Nm maximum torque. Its permanent magnet synchronous motor design ensures high efficiency, low rotor inertia, smooth operation, and excellent overload capability, making it ideal for high-performance positioning and speed control applications.
The 1FT7102-5AB71-1BL1 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 1BL1 suffix identifies a specific encoder and connector configuration within the SIMOTICS S-1FT7 family while maintaining the same core mechanical and electrical performance. The exact encoder resolution and feedback type are defined by the complete Siemens MLFB ordering code.
