Siemens 1FK7040-2AK71-1RH2 AC Synchronous Motor

Siemens SIMOTICS S synchronous motor, model 1FK7040-2AK71-1RH2, is a 0.69 kW 600 V-class servo motor in the 1FK7 family with a rated speed of 6,000 rpm and a nominal torque of 1.6 Nm (100 K). It uses natural cooling in an IMB 5 enclosure (IM V1, IM V3), features flange mounting with a rotatable power connector for flexible installation, and carries a 20‑bit absolute encoder plus 12‑bit multiturn feedback via the DRIVE-CLiQ interface (encoder AM20DQI). The motor is IP65 protected and integrates with Siemens drives to provide precise, repeatable motion for automated applications. Typical uses include positioning and drive tasks on conveyors, packaging lines, and robotic axes where a compact, high-precision motor is advantageous and a 600 V supply is available.
