Siemens 1Fk7040-5Ak71-1Dg0 Servo Motor

Siemens SIMOTICS S synchronous servo motor, model 1FK7040-5AK71-1DG0, is a compact 1FK7 servo solution delivering 1.6 Nm of continuous torque and up to 6,000 rpm. With a mechanical power rating of about 0.69 kW in natural cooling (IM B5) configurations, it pairs a robust drive system with high-precision feedback via a 2048‑pulse encoder that enables accurate closed‑loop control. The motor is IP64 protected, designed for industrial environments, and features a power/signal connector rotatable through 270° for flexible mounting. It uses Drive‑CLiQ interface for streamlined connectivity to Siemens motion controllers and supports a smooth shaft with tolerances of N, and it is specified without an integrated holding brake (DG0 variant). Mounting is in the IM B5 class (V1/V3 variants), aligning with common industrial automation setups. Typical applications include precise axis control in robotics, CNC tooling, pick-and-place machines, packaging lines, and other automation tasks where compact size, repeatable positioning, and reliable torque are required.
