Ma ka
i kēia manawa, ua hoʻohana nui ʻia ʻo NdFeB i nā ʻano āpau, e like me nā robots,
nā kaʻa ʻenehana, nā mea hana hale, nā pepeiao pepeiao, a pēlā aku
hoʻolauna i ka hoʻohana ʻana o NdFeB mau mākēneki mau i nā kaʻa ikehu hou.
ʻO nā kaʻa ikaika hou ka nui o nā kaʻa hybrid a me nā kaʻa uila maʻemaʻe.
Hoʻohana nui ʻia nā mea hoʻohana kiʻekiʻe NdFeB paʻa i ka hoʻokele
nā kaʻa o nā kaʻa ikehu hou. Hoʻokele kaʻa kūpono no nā kaʻa ikehu hou
ʻO ka mea nui e hoʻokomo i nā kaʻa hoʻokalakupua mau, AC asynchronous motors a
ke hoʻololi ʻana i ka magnetic i waena o lākou, aia ka mīkini paʻa paʻa synchronous
e lilo i kaʻa kaʻa nui ma muli o kona ākea ākea, mana kiʻekiʻe
ka nui, ka liʻiliʻi, a me ka pono kiʻekiʻe. Loaʻa iā NdFeB mau mākēneki mau ka
nā hiʻohiʻona o ka huahana ikehu magnetic kiʻekiʻe, kiʻekiʻe intrinsic coercive ikaika
a me ka remanence kiʻekiʻe, hiki ke hoʻomaikaʻi maikaʻi i ka mana a me ka torque
ka nui o nā kaʻa, a hoʻohana nui ʻia i nā rotors kaʻa magnet mau loa.
EPS
(Electric Power Steering System) ʻo ia ka mea hoʻohana i ka mea mau loa
magnets (0.25kg / kaʻa) i hoʻohui i ke kaʻa kaʻa. Ka mana-kōkua
ʻO ka micromotor i ka EPS he mīkini magnet mau loa, nona nā koi kiʻekiʻe no
hana, kaumaha a me ka leo. No laila, nā mea magnet mau i loko
ʻO ka EPS ka nui o nā kiʻekiʻe kiʻekiʻe i hoʻopaʻa ʻia a i ʻole nā mea hoʻokalakupua NdFeB.
In
hoʻohui i ke kaʻa hoʻokele o nā kaʻa ikehu hou, nā kaʻa ma ke koena o
ʻO ke kaʻa he micro-motors. Loaʻa i nā micro-motors nā koi haʻahaʻa i ka magnetism.
I kēia manawa, ʻo ka ferrite ka mea nui. Eia nō naʻe, ʻoi aku ka maikaʻi o ka hoʻohana ʻana i nā kaʻa
Hoʻonui ʻia ka NdFeB e 8-50%. Hoʻemi ʻia ka hoʻohana mana e 10% a me ka
Ua ho'ēmiʻia ke kaumaha ma mua o 50%, i lilo i ka ulu ulu o
nā mīkini micro i ka wā e hiki mai ana.
No ka mea
Eia kekahi laʻana, ʻo nā mea ʻike like ʻole ma nā kaʻa kahi hiʻohiʻona kahi e loaʻa ai nā magnet mau loa NdFeB
pili i nā kaʻa ikehu hou. ʻO nā mea ʻike e hoʻohana nui i nā magnet mau loa
i loko o: mamao naʻau, brake naʻau, noho kāʻei naʻau, etc
hoʻohana i nā mea ʻike Hall. I loko o nā mea ʻike Hall, hoʻohana ʻia nā magnet mau loa e hana
nā māla magnetic e hana i nā mea Hall e hoʻohua i nā au offset, no laila
e hana ana i ka ikaika electromotive, me ka miniaturization a me ka hoʻohui ʻana o
ʻO ka hoʻomohala ʻana o ka Hall sensor, ke koho ʻana i nā magnet mau loa e hoʻohana i ka NdFeB
nā mākēneki paʻa me nā waiwai magnetic maikaʻi a me ka liʻiliʻi.
Kaʻa
ʻO nā mea haʻiʻōlelo kekahi wahi ʻē aʻe kahi i hoʻohana ʻia ai nā magnet mau loa NdFeB
nā kaʻa ikehu hou. ʻO ka hana o nā magnet mau loa he hopena pololei
ma ka maikaʻi o ka leo o nā mea leo. ʻOi aku ke kiʻekiʻe o ka mākēneki flux density o
nā magnet mau loa, ʻoi aku ka kiʻekiʻe o ka naʻau o nā mea ʻōlelo a ʻoi aku ka maikaʻi
ka mea kuewa. ʻO ka ʻōlelo maʻamau, ʻo ia ka mea haʻiʻōlelo He maʻalahi ke hana a
kani, aole lepo ka leo. ʻO nā mākēneki mau o nā mea ʻōlelo ma ka
ʻO ka mākeke ka nui o AlNiCo, ferrite a me NdFeB. ʻO nā waiwai magnetic o
ʻOi aku ka maikaʻi o ka NdFeB ma mua o ka AlNi a me ka ferrite. ʻOi aku no ka kiʻekiʻe
nā mea ʻōlelo, hoʻohana ka hapa nui o lākou i ka NdFeB.
ʻO kā mākou
Hāʻawi ka hui i nā ʻano NdFeB, NdFeB i hoʻopaʻa ʻia, injection molded magnetic
nā apo, ferrite magnetic tile, NdFeB ikaika magnetic tile, etc. Hāʻawi mākou
nā lawelawe maʻamau no nā mea kūʻai aku, e ʻoluʻolu e hoʻokaʻaʻike mai iā mākou inā pono ʻoe.
