No ka māhele SmCo magnet, Sm2Co17 makemake nui aku ma mua o SmCo5, ma muli o ke kumu kūʻai kiʻekiʻe a me ka haʻahaʻa haʻahaʻa magnetic waiwai oSmCo5 magnet. ʻOkoʻa ka ʻenehana hana ʻoi aku ka hana wili ma waena o SmCo5 a me Sm2Co17. No ka SmCo5 magnet, hoʻohana ʻia ka wili pulu a i ʻole ka wili pōleʻa e hana i nā mea maka e lilo i pauka, akā he mau hemahema kēia ʻenehana me ka haʻahaʻa haʻahaʻa, haʻahaʻa haʻahaʻa ma waena o nā pūʻulu, a laila kiʻekiʻe ke kumu kūʻai. I ka hana ʻana i ke kaʻina hana arc, ua maʻalahi ka magnet i ka magnetize hapa a lilo ka ʻili o ka arc magnet i lepo. Hoʻohana ʻia ka milling Jet e hana i ka pauka no ka magnet Sm2Co17. ʻO ka mea maʻamau e hana ʻia ke ʻano arc e ka ʻoki uwea EDM me ka haʻahaʻa haʻahaʻa a me ka hoʻomanawanui ma kahi o +/- 0.1 mm, a i kekahi manawa e waiho ʻia nā ala uea molybdenum ma ka ʻili o ka radius. ʻO ke ʻano wili ʻana he mea ʻē aʻe e wili ai i ka ʻili R e loaʻa ai ke ahonui a me ka maʻalahi.
ʻO ka sealless magnetic drive pump a me ka hoʻopili ʻana ʻo ia kekahi mākeke noi nui no nā mea hoʻokalakupua SmCo. Hoʻohui ʻia nā mākēneki SmCo arc a i ʻole nā papana ma luna o ka impeller i loko o ka hale i hoʻopaʻa ʻia me ka hermetically a ma waho o ka hale. Ma muli o nā waiwai magnetic kiʻekiʻe o Sm2Co17 segment magnets, ʻo ka huki ʻana o ka magnet drive a me ka impeller magnet e hiki ai i ka torque piha o ke kaʻa ke hāʻawi ʻia i ka impeller. Hoʻopau kēia ʻano hoʻolālā mag-drive pump i ka pono no ka sila ʻana o ka shaft, a laila pale i nā wai kemika corrosive a i ʻole ke kinoea e pakele ai a leak a laila e hōʻeha i nā mea hana a me ke kaiapuni. Nui nā mea hana kaulana o nā pāpaʻi magnetically-driven a i ʻole couplings ma ka honua likeʻIwaki, Pan World,ʻo Sundyne, Magnatex, DST Dauermagnet-SystemTechnik, etc.
