Description
Product Description
The Siemens 1FT7102-5AB71-1KB4 is a SIMOTICS S-1FT7 permanent magnet synchronous servo motor designed for precision motion control in high-performance industrial automation systems. Engineered for seamless integration with Siemens SINAMICS S120 servo drive systems, this motor delivers exceptional positioning accuracy, high torque density, rapid dynamic response, and dependable continuous-duty performance. It is ideally suited for CNC machine tools, industrial robotics, packaging machinery, material handling systems, semiconductor manufacturing, printing equipment, and automated production lines.
Delivering 4.08 kW of rated output power at 1,500 RPM, the motor provides 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, excellent overload capability, and smooth, accurate motion for demanding industrial applications.
The 1FT7102-5AB71-1KB4 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 1KB4 suffix denotes a specific encoder and connector configuration within the SIMOTICS S-1FT7 family while maintaining the same core mechanical and electrical specifications as other 1FT7102-5AB71 variants. The exact encoder option is determined by the Siemens MLFB configuration.
