Nā noi o nā neodymium magnets i nā kaʻa uila
I kēia lā, ua hoʻonui nui ʻia nā noi o nā neodymium magnets i nā kaʻa uila, ʻoi aku ka nui o ka ulu ʻana o nā koi e noho nei me nā kaʻa uila i ka mākeke automotive honua.
Aia nā kaʻa uila a me nā ʻenehana hou hou i ka mua a he kuleana koʻikoʻi nā magnet e pāʻani i ka wā e hiki mai ana o ka ʻoihana honua a me ka halihali.Hana ʻia nā magnet Neodymium ma ke ʻano he stator a i ʻole ʻāpana o kahi kaʻa uila kuʻuna ʻole e neʻe.ʻO nā rotors, ka ʻāpana neʻe, he hui electromagnetic neʻe e huki ana i nā pods ma loko o ka paipu.
I nā kaʻa uila, ʻoi aku ka maikaʻi o nā neodymium magnets ke ʻoi aku ka liʻiliʻi a me ka māmā o nā kaʻa.Mai ka mīkini e wili ai i kahi disiki DVD a i nā huila o kahi kaʻa hybrid, hoʻohana ʻia nā magnet neodymium a puni ke kaʻa.
Hiki i ka neodymium magnet me kahi haʻahaʻa haʻahaʻa o ka coercivity ke hoʻomaka e nalowale i ka ikaika inā wela a ʻoi aku ma mua o 80°C.Ua hoʻomohala ʻia nā magnet neodymium coercivity kiʻekiʻe e hana i nā mahana a hiki i 220 ° C, me ka liʻiliʻi o ka nalowale.ʻO ka pono no ka haʻahaʻa haʻahaʻa haʻahaʻa i nā noi neodymium magnet i alakaʻi i ka hoʻomohala ʻana i nā helu he nui e hoʻokō i nā koi o ka hana.
I nā kaʻa āpau a me nā hoʻolālā e hiki mai ana, ʻoi aku ka maikaʻi o ka nui o nā kaʻa uila a me nā solenoids i nā helu pālua.Loaʻa lākou, no ka laʻana, ma:
-Nā kaʻa uila no nā puka makani.
- Nā motika uila no nā wipers makani.
-ʻO nā ʻōnaehana pani puka.
ʻO kekahi o nā mea koʻikoʻi i nā kaʻa uila he neodymium magnets.ʻO ka magnet ka mea maʻamau o ka ʻāpana o ke kaʻa a hāʻawi i ka mana hōʻole e hana i kahi neʻe pōʻai a laina laina.
ʻOi aku ka maikaʻi o nā neodymium magnets i nā kaʻa uila ma mua o nā ʻano magnets ʻē aʻe, ʻoi aku hoʻi i nā kaʻa hana kiʻekiʻe a i ʻole he mea koʻikoʻi ka hōʻemi ʻana i ka nui.Me ka hoʻomanaʻo ʻana i ka manaʻo o nā ʻenehana hou a pau e hōʻemi i ka nui holoʻokoʻa o ka huahana, aia paha e lawe koke kēia mau mīkini i ka mākeke holoʻokoʻa.
Hoʻohana nui ʻia nā magnet Neodymium i ka ʻoihana kaʻa, a lilo i koho koho no ka hoʻolālā ʻana i nā noi magnetic hou no kēia ʻāpana.
Ke hoʻomau nei ka neʻe ʻana o ka honua i ka electrification o nā kaʻa.I ka makahiki 2010, hiki i ka 7.2 miliona ka nui o nā kaʻa uila ma nā alanui o ka honua, a ʻo 46% aia ma Kina.Ma ka 2030, manaʻo ʻia ka nui o nā kaʻa uila e pehu i 250 miliona, kahi ulu nui i ka manawa pōkole.
He kuleana koʻikoʻi ka mana o ka honua rare i nā kaʻa i hoʻohana ʻia e nā ʻenekini puhi ahi a me nā ʻenekini uila.ʻElua mau mea koʻikoʻi i loko o kahi kaʻa uila e hōʻike ana i nā mea hoʻokalakupua honua;nā kaʻa a me nā mea ʻike.ʻO Motors ka manaʻo.
Loaʻa i nā kaʻa uila uila (EVs) ka hoʻoikaika ʻana mai kahi kaʻa uila ma mua o ka ʻenekini hoʻopau i loko.ʻO ka mana e hoʻokele ai i ke kaʻa uila mai kahi pūʻolo pākahi traction nui.No ka mālama ʻana a me ka hoʻonui ʻana i ke ola pākaukau, pono e hana maikaʻi ke kaʻa uila.
ʻO nā mākēneki kekahi mea nui i nā kaʻa uila.E holo ana ke kaʻa i ka wā e wili ai ka wili uea, i hoʻopuni ʻia e nā magnet ikaika.ʻO ke au uila i hoʻokomo ʻia i loko o ka coil e hoʻokuʻu i kahi māla magnetic, e kūʻē ana i ke kahua magnetic i hoʻokuʻu ʻia e nā magnet ikaika.Hoʻokumu kēia i kahi hopena hoʻopailua, e like me ka hoʻokomo ʻana i ʻelua mau mākēneki pole ʻākau ma hope o kekahi.
ʻO kēia hoʻokuke ʻana ke kumu o ka wili i ka wili a i ʻole ka ʻōwili ʻana i ka wikiwiki kiʻekiʻe.Hoʻopili ʻia kēia huila i kahi axle a ʻo ka hoʻohuli ʻana i nā huila o ke kaʻa.
Ke hoʻomau nei ka ʻenehana Magnet e hoʻokō i nā koi hou o nā kaʻa uila.I kēia manawa, ʻo ka magnet maikaʻi loa i hoʻohana ʻia i nā kaʻa no nā kaʻa hybrid a me nā kaʻa uila (ma ke ʻano o ka ikaika a me ka nui) ʻo Rare Earth Neodymium.ʻO Dysprosium i hoʻohui ʻia i ka palena palaoa i hoʻonui i ka ikehu kiʻekiʻe, e hopena i nā ʻōnaehana liʻiliʻi a ʻoi aku ka maikaʻi.
Hoʻohana ka awelika hybrid a i ʻole kaʻa uila ma waena o 2 a me 5 kg o Rare Earth magnet, ma muli o ka hoʻolālā.Hōʻike ʻia nā magnet rare earth i:
- Nā ʻōnaehana hoʻomehana, hoʻoheheʻe a me ka ea (HVAC);
-Ka hoʻokele, ka lawe ʻana a me nā kaʻa;
-Hybrid engine a i ʻole ʻāpana kaʻa uila;
- Nā ʻike e like me ka palekana, nā noho, nā kāmera, a me nā mea ʻē aʻe;
- Puka a me nā puka makani;
- Pūnaehana leʻaleʻa (nā mea haʻi'ōlelo, radio, etc.);
-Nā ʻōhua kaʻa uila
-ʻO nā ʻōnaehana hoʻoheheʻe a me nā ʻōnaehana no nā Hybrids;
Ma ka 2030, ʻo ka ulu ʻana o nā kaʻa uila e hoʻonui i ka noi no nā ʻōnaehana magnetic.I ka ulu ʻana o ka ʻenehana EV, hiki ke neʻe aku nā noi magnet i loaʻa mai nā mea hoʻokalakupua honua i nā ʻōnaehana ʻē aʻe e like me ka reluctance hoʻololi a i ʻole nā ʻōnaehana magnetic ferrite.Eia nō naʻe, ke manaʻo ʻia nei e hoʻomau ka neodymium magnets i ka hana koʻikoʻi i ka hoʻolālā ʻana o nā ʻenekini Hybrid a me ke keʻena kaʻa uila.No ka hoʻokō ʻana i kēia koi hoʻonui i manaʻo ʻia no ka neodymium no nā EV, manaʻo nā mea loiloi mākeke:
- Hoʻonui i ka huahana e Kina a me nā mea hana neodymium ʻē aʻe;
-Ka hoʻomohala ʻana i nā waihona hou;
- Ka hana hou ʻana o nā magnet neodymium i hoʻohana ʻia i nā kaʻa, nā uila a me nā noi ʻē aʻe;
Hana ʻo Honsen Magnetics i kahi ākea o nā mea magnet a me nā hui magnetic.Nui nā mea no nā noi kikoʻī.No ka ʻike hou aku e pili ana i kekahi o nā huahana i ʻōlelo ʻia ma kēia loiloi, a i ʻole no nā hui magnet bespoke a me nā hoʻolālā magnet, e ʻoluʻolu e kelepona mai iā mākou ma o ka leka uila o ke kelepona.
