Description
Product Description
The Siemens 1FT7102-5AB71-1BB2 is a premium SIMOTICS S-1FT7 permanent magnet synchronous servo motor designed for high-performance motion control applications. Engineered for seamless integration with Siemens SINAMICS S120 drive systems, it provides exceptional positioning accuracy, fast dynamic response, and outstanding reliability for CNC machine tools, robotics, packaging machinery, material handling systems, and automated production lines.
This servo motor delivers an optimum output power of 4.1 kW at a rated speed of 1,500 RPM, producing a rated torque of 26 Nm, stall torque of 30 Nm (100 K), and a maximum torque of 120 Nm. Its permanent magnet rotor provides high torque density, excellent energy efficiency, and low rotor inertia for superior acceleration and precise motion control.
The 1FT7102-5AB71-1BB2 features natural cooling, an IM B5 flange mounting, IP65 protection, a plain shaft, an integrated Pt1000 temperature sensor, and a high-resolution encoder for precise speed and position feedback. The turnable SPEED-CONNECT power connector enables quick installation and simplified maintenance, making it ideal for demanding industrial environments. Configuration-specific encoder options are determined by the complete Siemens MLFB ordering code.
