Siemens 1FK7042-2AF71-1RH0 Servo Motor

Siemens SIMOTICS S-1FK7 servo motor, model 1FK7042-2AF71-1RH0, is a 0.82 kW, 600 V synchronous servo motor (1FK7-CT) with M0 3 Nm and Nn 3,000 r/min, designed for natural cooling in MB5 construction and IM V1/IM V3 mounting. It features a flange 1 configuration and a rotatable power connector for flexible installation, a smooth shaft with tolerance N, and a built‑in holding brake for secure positioning when power is removed. The motor integrates a Drive-CLiQ interface with an AM20DQI absolute encoder that provides 20-bit single-turn and 12-bit multi-turn position data, enabling precise feedback for closed‑loop control. Protected to IP64, this SIMOTICS S-1FK7 device is part of Siemens' high‑precision servo family and is well suited for automation tasks that demand reliable torque, speed, and encoder feedback in compact enclosures.
