Description
Product Description
The Siemens 1FT7102-5AB71-1BB5 is a premium SIMOTICS S-1FT7 permanent magnet synchronous servo motor designed for high-performance motion control applications requiring exceptional precision, dynamic response, and long-term reliability. Optimized for operation with Siemens SINAMICS S120 drive systems, this servo motor is ideal for CNC machine tools, robotics, packaging machinery, printing equipment, material handling systems, and automated production lines.
Delivering an optimum output power of 4.1 kW at a rated speed of 1,500 RPM, the motor provides 26 Nm rated torque, 30 Nm stall torque (100 K), and a maximum torque of 120 Nm. Its permanent magnet synchronous design offers excellent efficiency, high torque density, low rotor inertia, and outstanding positioning accuracy, making it suitable for demanding industrial automation applications.
The 1FT7102-5AB71-1BB5 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. A turnable SPEED-CONNECT power connector enables fast installation and simplified maintenance. Configuration-specific options such as encoder type, connector orientation, and optional holding brake are determined by the complete Siemens MLFB ordering code.
