Hiki ke paʻi ʻia ke kumu kaʻa 3D? ʻO ka holomua hou i ke aʻo ʻana i nā core magnetic motor ʻO ke kumu magnetic he mea like me ka laula me ke kiʻekiʻe magnetic permeability.Hoʻohana pinepine ʻia lākou no ke alakaʻi ʻana i ke kahua magnetic i nā ʻōnaehana uila a me nā mīkini, me nā electromagnets, transformers, motors, generators, inductors a me nā mea magnetic ʻē aʻe. I kēia manawa, ua paʻakikī ka paʻi 3D o nā cores magnetic ma muli o ka paʻakikī o ka mālama ʻana i ka pono kumu.Akā ua hōʻea mai kahi hui noiʻi me kahi kaila hana hana hoʻohui laser-based piha i ʻōlelo ʻia e hiki ke hana i nā huahana i ʻoi aku ka maikaʻi ma mua o nā composites soft-magnetic. ©3D Science Valley Pepa Keʻokeʻo
3D paʻi mea electromagnetic
ʻO ka hana hoʻohui ʻana o nā metala me nā waiwai electromagnetic kahi kahua noiʻi e kū nei.Ke kūkulu nei kekahi mau hui R&D kaʻa kaʻa a hoʻohui i kā lākou mau mea paʻi 3D ponoʻī a hoʻopili iā lākou i ka ʻōnaehana, a ʻo ke kūʻokoʻa hoʻolālā kekahi o nā kī o ka hana hou. No ka laʻana, hiki i nā ʻāpana paʻakikī paʻi paʻi 3D me nā waiwai magnetic a me ka uila ke hoʻokaʻawale i ke ala no nā motika i hoʻopili ʻia, nā mea hana, nā kaapuni a me nā pahu pahu.Hiki ke hana ʻia ia mau mīkini i loko o nā hale hana kikohoʻe me ka liʻiliʻi o ka hui ʻana a me ka hoʻoponopono ʻana, a me nā mea ʻē aʻe, no ka mea, ua paʻi ʻia nā ʻāpana he 3D.Akā no nā kumu like ʻole, ʻaʻole i hoʻokō ʻia ka ʻike o ka paʻi ʻana o 3D nui a paʻakikī.ʻO ka mea nui no ka mea aia kekahi mau koi paʻakikī ma ka ʻaoʻao o ka hāmeʻa, e like me nā ʻāpana ea liʻiliʻi no ka hoʻonui ʻana i ka mana mana, ʻaʻole e haʻi i ka hoʻopuka ʻana o nā ʻāpana multi-material.I kēia manawa, ua nānā ka noiʻi i nā mea "kumu" hou aʻe, e like me 3D-printed soft-magnetic rotors, coils coils, a me nā mea hoʻokele wela alumina.ʻO kaʻoiaʻiʻo, ʻo nā core magnetic palupalu kekahi o nā mea nui, akā ʻo ka pilikia nui e hoʻonā ʻia i ke kaʻina paʻi 3D ʻo ia ka mea e hōʻemi ai i ka poho kumu.

Aia ma luna aʻe he pūʻulu o 3D i paʻi ʻia i nā ʻāpana cubes e hōʻike ana i ka hopena o ka mana laser a me ka wikiwiki o ka paʻi ʻana i ke ʻano o ka mea magnetic.
ʻO ke kaʻina hana paʻi 3D i hoʻonui ʻia
No ka hōʻike ʻana i ka 3D paʻi magnetic core workflow, ua hoʻoholo nā mea noiʻi i nā ʻāpana kaʻina hana maikaʻi loa no ka noi, me ka mana laser, ka wikiwiki scan, ka hatch spacing, a me ka mānoanoa papa.A ua aʻo ʻia ka hopena o nā ʻāpana annealing e hoʻokō i nā poho DC haʻahaʻa, quasi-static, nā poho hysteresis a me ka permeability kiʻekiʻe.Ua hoʻoholo ʻia ka mahana annealing maikaʻi loa he 1200°C, ʻo 99.86% ka pili pili kiʻekiʻe, ʻo ka haʻahaʻa haʻahaʻa haʻahaʻa roughness ʻo 0.041mm, ʻo ka haʻahaʻa haʻahaʻa haʻahaʻa hysteresis he 0.8W/kg, a ʻo ka hopena hope loa he 420MPa. ▲ʻO ka hopena o ka hoʻokomo ʻana i ka ikehu ma luna o ka ʻeleʻele o ka ʻili 3D i pai ʻia
ʻO ka mea hope loa, ua hōʻoia ka poʻe noiʻi ʻo ka hana ʻana i nā mea hoʻohui metala i hoʻokumu ʻia i ka laser he ala kūpono no ka paʻi ʻana i ka mīkini paʻi magnetic core material.Ma ka hana noiʻi e hiki mai ana, manaʻo ka poʻe noiʻi e hōʻike i ka microstructure o ka ʻāpana e hoʻomaopopo i ka nui o ka palaoa a me ke ʻano o ka palaoa, a me kā lākou hopena i ka permeability a me ka ikaika.E noiʻi hou ka poʻe noiʻi i nā ala e hoʻomaikaʻi ai i ka geometry core paʻi 3D e hoʻomaikaʻi i ka hana.
