Description
Product Description
The Siemens 1FT7102-5AB71-1KA3 is a SIMOTICS S-1FT7 permanent magnet synchronous servo motor engineered for precision motion control in demanding industrial automation applications. Designed for seamless integration with Siemens SINAMICS S120 servo drive systems, this motor delivers outstanding positioning accuracy, high torque density, rapid acceleration, and reliable continuous-duty operation. It is an excellent choice for CNC machine tools, robotics, packaging machinery, material handling systems, semiconductor manufacturing equipment, printing machinery, 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 technology ensures high efficiency, low rotor inertia, smooth motion, and excellent overload capability for demanding servo applications.
The 1FT7102-5AB71-1KA3 features natural cooling, IM B5 flange mounting, a plain shaft, IP65 protection, integrated Pt1000 temperature monitoring, and a high-resolution encoder with DRIVE-CLiQ interface. The 1KA3 suffix designates a specific encoder and connector configuration within the SIMOTICS S-1FT7 product family while maintaining the same core mechanical and electrical characteristics as other 1KA-series variants.
