SIMOTICS S 1FK7 Compact design Includes holding brake Absolute encoder with Drive-Cliq Naturally cooled IP64 protection Plain shaft

Product description

The Siemens SIMOTICS S 1FK7042-5AK71-1FH3 is a compact synchronous servo motor featuring a 3.0 Nm torque, 6000 rpm speed, and 1.02 kW power output, naturally cooled. It is equipped with an absolute encoder (2048 P/REV) with a Drive-Cliq interface and a plain shaft with tolerance N. This model includes a holding brake, a degree of protection IP64, and a RAL7016 paint finish. Similar to other 1FK7 compact motors, it experiences a 10% performance reduction due to the absolute encoder.

This motor is well-suited for applications requiring precise motion control and the ability to hold position when power is removed, such as in vertical axes of CNC machines, robotics, and automated assembly lines. Industries benefiting from this include manufacturing, packaging, and material handling.
