Synchronous Servo Motor High Precision EnDat Encoder IP65 Rated Seal Smooth Shaft Design Natural Cooling Dynamic Performance

The Siemens SIMOTICS S 1FT6 synchronous servo motor, part number 1FT6031-4AK71-3EG1, is designed for high-performance motion control. This motor provides 1.0 Nm of torque and operates at 6000 RPM, with an output power of 0.47 kW. It features natural cooling and is built for IM B5 mounting (IM V1, IM V3). The motor includes a power and signal connector outlet on the axial non-drive end (NDE). It is equipped with an Absolute Encoder EnDat 2048 S/R (Type A-2048) and experiences a 10% derating due to the encoder. The shaft is smooth, with a circular runout tolerance of N, and it operates without a holding brake. Vibration severity grade is N, and it utilizes a Gamma sealing ring for an IP65 protection rating.

This servo motor is ideal for applications demanding high precision, dynamic response, and accurate position feedback, such as advanced robotics, automated production lines, and high-speed machinery. Key industries include semiconductor manufacturing, electronics assembly, and specialized industrial automation where reliable and precise motion is paramount.
