A permanent-magnet synchronous servomotor of this frame is built around a resolver or encoder feedback loop on the drive side, which is why the order-code suffix (the -1PH3 segment) carries the encoder / shaft / holding-brake permutation — drop the motor onto the matching SINAMICS drive topology and the controller handles the commutation and the safety stop without further wiring. ## Why the eol_hot flag changes the procurement decision For a spare-parts buy this shifts the sourcing question: confirm the encoder variant on the nameplate (the -1PH3 suffix is the differentiator, not the frame), then pull an RFQ against the available independent stock — lead time and pricing are confirmed at quote rather than off a published lead-time ladder.","metaTitle":"Siemens 1FK7042-5AF71-1PH3 Servo Motor, 1FK7 Compact","metaDescription":"Siemens 1FK7042-5AF71-1PH3 1FK7 compact synchronous servo motor, listed at 5.73 kgs, lifecycle stage eol_hot.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Servo Motors"],"specifications":{"title":"1FK7042-5AF71-1PH3","Part #":"1FK7042-5AF71-1PH3","Weight":"5.73 kgs","Category":"Motors","description":"1FK7042-5AF71-1PH3 - 1FK7 COMPACT SYNCHRONOUS MOTOR by SIEMENS","Sub Category":"Servo Motors","Top Category":"Motors & Motor Controls","lifecycle_stage":"eol_hot"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2,578.93","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/647530720402e9bdb23d5fbad456dc20.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/1FK7042-5AF71-1PH3","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/1FK7042-5AF71-1PH3 when reusing this data.
