Product description

The Siemens 1FT6081-8AF71-4EB4 is a SIMOTICS S synchronous servo motor from the 1FT6 family, delivering 8.0 Nm of torque at 3000 rpm. It features natural cooling and IM B5 mounting. This model is equipped with an absolute encoder (EnDat 2048 S/R) for precise positioning, a feather key, and a holding brake for secure stops. Due to the absolute encoder, a 10% derating is applied. It has a Gamma sealing ring providing an IP65 rating.

This servo motor is designed for high-precision automation tasks where exact positioning and dynamic response are crucial. Applications include advanced machine tools, precision assembly systems, and automated inspection equipment. The absolute encoder ensures immediate position data upon startup, and the holding brake adds safety and stability.

Frequently asked questions

What is the purpose of the 10% derating on the Siemens 1FT6081-8AF71-4EB4?

The 10% derating is applied because the absolute encoder (EnDat 2048 S/R) consumes slightly more power than an incremental encoder. This ensures the motor operates within its thermal limits under all conditions.
