Noi o NdFeB mau Magnets ma na kaa ikehu hou

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.
