That combination puts it in the high-pole-count, low-inertia corner of the family: pair it with a SINAMICS S120 or S210 drive module, encoder and resolver feedback resolved through the motor connector, and confirm the rated point on the speed-torque curve against the application duty cycle before sizing. Lifecycle is flagged EOL hot: the part is still moving through last-time-buy or hot-stock channels while the platform is wound down. Independent distributors quote it against an RFQ rather than from a published catalog line; lead time and lot traceability are confirmed at quote time, not on the page. ## Where this stator lands in a panel or machine 1FK7-series synchronous servos of this frame are typically specified where positioning bandwidth and dynamic stiffness matter more than continuous torque — small CNC auxiliary axes, indexing tables, high-speed pick-and-place modules, and the feed/spindle-drive pair on a converted tool-room mill. The motor body is the standard SIMOTICS shaft-and-flange interface for this stator length; the holding-brake option (resolver / absolute encoder variant) is part of the order-code suffix and must be confirmed against the BOM before quoting. Pairs of SIMOTICS servos from the same frame family — 1FK7042-5AF71-1DB0, 1FK7042-5AF21-1UA0 and 1FK7042-5AK71-1KG3 — are nearby entries in the same family tree. They share the 1FK7 mounting envelope but differ in stack length, rated torque and feedback option; a panel that was originally specified against one of those codes may not be a direct drop-in for the 1FK70434CH711QG0 — the order-code suffix and the drive-side parameter block both have to match the substituted motor. ## Sourcing posture for an EOL-hot stator Most quotes arrive as lot-specific offers tied to the available factory-pulled or surplus inventory; pricing and date-code traceability are both confirmed at RFQ time. Lead-time stability on EOL-hot parts is exposure-dependent — request the date code, the test report, and the encoder / brake configuration in writing before committing the BOM line.","metaTitle":"Siemens 1FK70434CH711QG0 Servo Motor, 3.1 Nm, 1.23 kW, EOL","metaDescription":"Siemens 1FK70434CH711QG0 synchronous servo, 3.1 Nm / 1.23 kW / 4500 rpm, lifecycle hot EOL.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Servo Motors"],"specifications":{"title":"1FK70434CH711QG0","Part #":"1FK7043-4CH71-1QG0","Weight":"5.90 kgs","Category":"Motors","description":"MOTOR SYNC 3AC 3.1NM 1.23KW 4500RPM|MOTOR SYNC 3AC 3.1NM 1.23KW 4500RPM","Sub Category":"Servo Motors","Top Category":"Motors & Motor Controls","lifecycle_stage":"eol_hot"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$720.09","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/647530720402e9bdb23d5fbad456dc20.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy 1FK70434CH711QG0 and how do I get a price?","answer":"Independent distribution quotes against the BOM line — submit an RFQ with the full order-code suffix, target quantity and needed date code."},{"question":"Does 1FK70434CH711QG0 drop into a panel specified around 1FK7042-5AF71-1DB0 without rewiring?","answer":"Not as a guaranteed drop-in.
