Description
Product Description
The Siemens 1FT7102-5AB71-1BA3 is a premium SIMOTICS S-1FT7 permanent magnet synchronous servo motor engineered for high-precision motion control applications. Designed to operate with Siemens SINAMICS S120 drive systems, this servo motor delivers outstanding positioning accuracy, fast dynamic response, and exceptional reliability for CNC machine tools, robotics, packaging equipment, and automated manufacturing systems.
With an optimum output power of 4.1 kW at a rated speed of 1,500 RPM, the motor provides a rated torque of 26 Nm and a stall torque of 30 Nm (100 K). Its natural cooling design eliminates the need for external cooling, ensuring efficient and dependable continuous-duty operation while reducing maintenance requirements.
The 1FT7102-5AB71-1BA3 features an 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 turnable SPEED-CONNECT power connector simplifies installation and provides secure electrical connections in demanding industrial environments. Configuration-specific encoder and connector options are determined by the complete Siemens MLFB code.
