SIMOTICS S-1FT7 Synchronous Motors Compact 1FT7102-5AB71-1KA0

Product Description

The Siemens 1FT7102-5AB71-1KA0 is a SIMOTICS S-1FT7 permanent magnet synchronous servo motor engineered for high-precision motion control in demanding industrial automation applications. Designed for seamless integration with Siemens SINAMICS S120 drive systems, this servo motor delivers outstanding positioning accuracy, high torque density, rapid dynamic response, and reliable continuous-duty performance. It is ideal for CNC machine tools, robotics, packaging equipment, material handling systems, semiconductor manufacturing, printing machinery, and automated production lines.

With a rated output power of 4.08 kW at 1,500 RPM, the motor delivers 26 Nm rated torque, 30 Nm stall torque (100 K), and up to 120 Nm maximum torque. Its permanent magnet synchronous design provides high efficiency, low rotor inertia, smooth operation, and excellent overload capability, making it suitable for demanding positioning, interpolation, and synchronized motion applications.

The 1FT7102-5AB71-1KA0 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 1KA0 suffix denotes a specific encoder and connector configuration within the SIMOTICS S-1FT7 family while maintaining the same electrical and mechanical performance as other variants in the series.
