That envelope is the first thing a replacement check has to match, because a higher-torque motor in the same frame does not necessarily fit the same coupling or share the same drive parameter set. ## Rating envelope and what it locks in 3.1 Nm at 1.26 kW across a 6000 rpm speed range places this in the compact mid-inertia segment of the Siemens synchronous-servo line — sized for machine-tool axes, packaging indexing, and small-format converting or pick-and-place drives where the load inertia is moderate and the cycle rate is high. Three-phase AC synchronous operation means the 1FK70437AK711EH5 is fed from a Siemens SINAMICS-class servo drive; the drive commissioning profile, motor ID, and resolver/encoder feedback map are matched at the controller side, so a swap that keeps the frame but changes the feedback device forces a re-parameterisation pass on the controller before the axis will run cleanly. ## Sourcing posture for a phased-out servo No stock-holding or immediacy claim is made here; the kit lead depends on what the surplus lot carries when the RFQ lands.","metaTitle":"Siemens 1FK70437AK711EH5 servo motor, 3.1 Nm, 1.26 kW","metaDescription":"Siemens 1FK70437AK711EH5 synchronous servo motor, 3 AC, 3.1 Nm, 1.26 kW, 6000 rpm — listed eol_hot; sourced to order against an RFQ.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Servo Motors"],"specifications":{"lifecycle_stage":"eol_hot"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/647530720402e9bdb23d5fbad456dc20.pdf","sourceUrl":null,"alternativesUrl":"https://aoctrl.com/api/mcp/products/1FK70437AK711EH5/alternatives.json"},"ai":{"faq":[{"question":"What is the listed description for 1FK70437AK711EH5?","answer":"The title row records MOTOR SYNC 3AC 3.1NM 1.26KW 6000RPM — a three-phase AC synchronous servo rated 3.1 Nm of continuous torque, 1.26 kW mechanical output, and a 6000 rpm top speed.
