The 1FK7 high-dynamic family is the short-stack, low-inertia end of Siemens' synchronous servo lineup — the rotor is built for aggressive acceleration profiles, and the frame is sized for machine-axis duty where cycle time matters more than continuous torque. ## Lifecycle status and what it means for the BOM line For a line-down or a long-lead replacement build, that translates into independent-distribution sourcing — surplus stock and broker-channel lots are the realistic supply path, and lead time is whatever the open market carries on the day of the RFQ. ## Where this frame sits against sibling 1FK7 motors A drop-in substitution against a 1FK7042-series motor requires a shaft-and-flange check as well as a torque-check; the frame length and the inertia both shift between the 1FK7042 and the 1FK7044, so a panel that was qualified against a 1FK7042 cannot accept this motor without mechanical and drive-parameter re-qualification.","metaTitle":"Siemens 1FK7044-4CF71-1QH0 Servo Motor, 7.71 kg","metaDescription":"1FK7044-4CF71-1QH0 Siemens 1FK7 high-dynamic synchronous servo motor, 7.71 kg, lifecycle stage EOL/hot.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Servo Motors"],"specifications":{"Part #":"1FK7044-4CF71-1QH0","Weight":"7.71 kgs","Category":"Motors","Sub Category":"Servo Motors","Top Category":"Motors & Motor Controls","lifecycle_stage":"eol_hot"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$883.92","priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/647530720402e9bdb23d5fbad456dc20.pdf","sourceUrl":null,"alternativesUrl":"https://aoctrl.com/api/mcp/products/1FK7044-4CF71-1QH0/alternatives.json"},"ai":{"faq":[{"question":"Can 1FK7044-4CF71-1QH0 drop into a panel built around 1FK7042-5AF71-1DB0?","answer":"Not without re-qualification — the 1FK7044 frame is longer and heavier (7.71 kg vs 5.44 kg for 1FK7042-5AF71-1DB0), and the shaft, flange, and torque profile do not match a 1FK7042-designated machine without mechanical rework and drive-parameter adjustment."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/1FK7044-4CF71-1QH0","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/1FK7044-4CF71-1QH0 when reusing this data.
