Description
Product Description
The Siemens 1FT7102-5AB71-1BE0 is a premium SIMOTICS S-1FT7 permanent magnet synchronous servo motor engineered for demanding industrial motion control applications requiring exceptional precision, high torque density, and superior dynamic performance. Designed for seamless integration with Siemens SINAMICS S120 drive systems, this servo motor is ideal for CNC machining centers, industrial robotics, packaging equipment, material handling systems, printing machinery, and automated manufacturing lines.
Delivering 4.1 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 design ensures high efficiency, rapid acceleration, low rotor inertia, and outstanding positioning accuracy for high-performance automation applications.
The 1FT7102-5AB71-1BE0 features natural cooling, IM B5 flange mounting, IP65 protection, a plain shaft, integrated Pt1000 temperature monitoring, and a high-resolution encoder for precise speed and position feedback. The 1BE0 suffix designates a specific encoder and electrical interface configuration within the SIMOTICS S-1FT7 series while maintaining identical mechanical performance. Encoder configuration is determined by the complete Siemens MLFB ordering code.
