Description
Product Description
The Siemens 1FT7102-5AB71-1BA5 is a high-performance SIMOTICS S-1FT7 permanent magnet synchronous servo motor designed for precision motion control in demanding industrial automation applications. Engineered for seamless integration with Siemens SINAMICS S120 drive systems, this servo motor delivers exceptional positioning accuracy, high torque density, and rapid dynamic response for CNC machine tools, robotics, packaging machinery, and automated manufacturing systems.
The motor delivers an optimum output power of 4.1 kW at a rated speed of 1,500 RPM, producing a rated torque of 26 Nm and a stall torque of 30 Nm (100 K). Its natural cooling design ensures efficient heat dissipation without external cooling equipment, making it suitable for continuous-duty industrial applications.
Featuring an IM B5 flange mounting, IP65 protection, plain shaft, integrated Pt1000 temperature sensor, and a high-resolution encoder, the 1FT7102-5AB71-1BA5 provides accurate speed and position feedback while ensuring long-term operational reliability. A turnable SPEED-CONNECT power connector simplifies installation and maintenance. Configuration-specific options such as encoder version or connector orientation are defined by the complete Siemens MLFB code.
