SIMOTICS S synchronous motor 1FK7 Compact series Basic absolute encoder DRIVE-CLiQ interface Plain shaft design IP64 protection 10% derating

Product description

The Siemens 1FK7034-5AK71-1VG0 is a SIMOTICS S synchronous servo motor from the 1FK7 Compact series. It delivers 1.6 Nm of torque at 6000 rpm with a 0.63 kW power output, naturally cooled. This model features a rotatable 270° power/signal connector plug and an integrated basic absolute encoder (16 S/R, encoder A-16) with a DRIVE-CLiQ interface. Due to the absolute encoder, a 10% derating applies. It has a plain shaft with tolerance N, no holding brake, and an IP64 degree of protection.

This servo motor is designed for high-precision positioning and motion control tasks in advanced automation applications. The basic absolute encoder provides immediate position feedback upon power-up, eliminating the need for homing routines and improving system efficiency. It's suitable for industries like robotics, packaging, and automated assembly.
