Description
Product Description
The Siemens 1FT7102-5AB71-1BB1 is a high-performance SIMOTICS S-1FT7 permanent magnet synchronous servo motor designed for precision motion control in demanding industrial automation environments. Engineered for seamless compatibility with Siemens SINAMICS S120 drive systems, this servo motor delivers exceptional dynamic response, high positioning accuracy, and reliable continuous-duty performance for CNC machinery, robotics, packaging systems, printing equipment, and material handling applications.
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 120 Nm maximum torque. Its permanent magnet rotor ensures high efficiency, low rotor inertia, and rapid acceleration for demanding servo applications.
The 1FT7102-5AB71-1BB1 features natural cooling, IM B5 flange mounting, IP65 protection, a plain shaft, integrated Pt1000 temperature sensor, and a high-resolution encoder for precise speed and position feedback. A turnable SPEED-CONNECT connector simplifies installation and maintenance. Configuration-specific options such as encoder type or connector orientation depend on the complete Siemens MLFB configuration.
