ʻO ka hoihoi o nā kaʻa ikehu hou ua hoʻokomo i ka ikaika hou i loko o nā lālā o ke kaulahao ʻoihana.
Wahi a kahi hōʻike noiʻi a Cerui, e piʻi ana ka hana kaʻa o Kina i 35 miliona i 2025, kahi o nā kaʻa ikehu hou e ʻoi aku ma mua o 20% o ka nui o ka hana kaʻa a me ke kūʻai aku, a hiki i 7 miliona.
Inā he kaʻa wahie maʻamau a i ʻole kaʻa ikehu hou, e hoʻokō ai i ka mālama ʻana i ka ikehu, ke kaumaha māmā, ka liʻiliʻi liʻiliʻi a me ka hana kiʻekiʻe, ʻo ka hoʻokomo ʻana i nā micro-motors hoʻōla ikehu kiʻekiʻe kekahi o nā ala nui.
Ua ʻōlelo ka luna loiloi hoʻolālā nui o Yuekai Securities Research Institute, ʻo ka mākeke kūloko no nā kaʻa kaʻa kiʻekiʻe e pili ana i ka 10%.Hiki ke hoʻohana ʻia nā micromotors kiʻekiʻe a me ka mālama ʻana i ka ikehu i ʻike mua ʻia e hoʻokō i kahi "huli nui".
ʻO ka neodymium iron boron magnet ka mea nui no nā kaʻa hoʻopakele ikehu kiʻekiʻe.
ʻO ka NdFeB Magnet he kristal tetragonal i haku ʻia me ka neodymium, ka hao a me ka boron (Nd2Fe14B), kahi neodymium no 25% a 35%, hao no 65% a 75%, a ʻo ka boron ma kahi o 1%.ʻO ia ke kolu o ka hanauna o ka honua paʻa mau mea hoʻopaneʻe, a he hana maikaʻi loa ia i nā "mea hoʻokalakupua" coefficients e like me ka intrinsic coercivity, ka ikehu ikehu a me ka remanence, a he "mike aliʻi" kūpono.
I kēia manawa, i ka mākeke noi haʻahaʻa o ka magnet NdFeB kiʻekiʻe, noho ka makani makani i kahi hapa nui o ka mākeke.Me ka hoʻomohala wikiwiki ʻana o nā kaʻa ikehu hou, ua hoʻomau ʻia ka noi ʻana o NdFeB magnet i nā kaʻa micro-special automotive, a e pahū ke koi no ka hana kiʻekiʻe NdFeB magnet ma ke kahua o nā kaʻa hou a me nā ʻāpana kaʻa.
