Definition and what the motor does
The 1FK7022-5AK71-1TG3 from Siemens is a 1FK7 compact synchronous servo motor — a brushless permanent-magnet rotor in a low-inertia housing built for high dynamic response on positioning axes, feed drives, and small-format machine tool spindles where fast acceleration and repeatable torque matter more than peak continuous output.
Sourcing posture and what to expect on an RFQ
Because no successor is in the ledger, the procurement question is not "what replaces it" but "how much buffer should I hold" — a controls integrator pulling this motor out for a running line usually pairs the order with a nameplate-and-PO traceable declaration pack to satisfy the supplier-quality check at goods-in.
