Description
Product Description
The Siemens 1FT7102-5AB71-1BD1 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, it offers exceptional dynamic response, high positioning accuracy, and dependable long-term performance for CNC machine tools, robotics, packaging machinery, printing equipment, material handling systems, and automated production lines. The 1BD1 configuration includes a specific encoder and connection variant within the SIMOTICS S-1FT7 product family while maintaining the same core motor performance.
Operating at a rated speed of 1,500 RPM, the motor delivers 4.1 kW rated output power, 26 Nm rated torque, 30 Nm stall torque (100 K), and 120 Nm maximum torque. Its permanent magnet rotor design provides high torque density, low rotor inertia, excellent energy efficiency, and outstanding acceleration for demanding servo applications.
The motor features natural cooling, IM B5 flange mounting, IP65 enclosure protection, a plain shaft, integrated Pt1000 temperature monitoring, and a high-resolution encoder for accurate speed and position feedback. The turnable SPEED-CONNECT power connector enables quick installation and simplified maintenance in industrial environments. Encoder version and connection options are determined by the complete Siemens MLFB configuration.
