Me ka ulu ikaika ʻana o ka ʻoihana uila, hoʻololi mālie ka ʻike kūlana o kekahi mau mea hoʻolālā mai ke ana hoʻopili kumu a i ke ana hoʻopili ʻole ma oMea ʻike kūlana Hall a me ka magnet.Pehea mākou e koho ai i kahi magnet kūpono e like me kā mākou huahana a me kā mākou hana?Maʻaneʻi mākou e hana i kahi kānana maʻalahi.
ʻO ka mea mua, pono mākou e hoʻoholo i ka mea magnet.I kēia manawa, hoʻohana nui ʻia ka samarium cobalt magnet a me ka neodymium iron boron i ka sensor kūlana hale.ʻO ka ʻokoʻa nui ma waena o nā magnet ʻelua, ʻo ia ka mea ma muli o ka nui like NdFeB magnet ʻoi aku ka ikaika ma mua o nā magnet samarium cobalt;ʻoi aku ka liʻiliʻi o ka huakaʻi wela o ka samarium cobalt ma mua o ka Nd-Fe-B;ʻoi aku ka ikaika o ka pale ʻana o ka samarium cobalt ma mua o ka Nd-Fe-B, akā ma ka maʻamau, aia kahi uhi ma waho o ka magnet, hiki ke hoʻoponopono i ka pilikia o ka oxidation;ʻoi aku ka maikaʻi o ka pale wela o ka samarium cobalt magnet ma mua o ka NdFeB magnet, akā hiki ke piʻi aku ka nui o ke kūpaʻa mahana no nā mea magnet ʻelua ma mua o 200 ℃.No laila, i ke koho ʻana i ke ʻano o ka magnet, pono mākou e loiloi i ka hui pū ʻana me ka hana kumukūʻai, ka mahana hana a me ke ʻano hana.Ma keʻano laulā, hiki ke hoʻohana hou ʻia ʻo NdFeB, no ka mea, ʻoi aku ka maikaʻi o nā hiʻohiʻona magnetic field.Eia nō naʻe, i ka hana ʻana i kahi ākea ākea, ʻōlelo ʻia e koho i ka samarium cobalt magnet ma muli o kona liʻiliʻi thermal drift.
Eia hou, pono mākou e hoʻoholo i kekahi mau palena kumu o ka magnet.Wahi a ka ʻike kūlana hoʻāʻo a me ka neʻe ʻana o ka mea, hoʻoholo mākou inā he diametrical a axial paha ke kuhikuhi magnetization o ka magnet.Eia kekahi, ua hoʻoholo ʻia inā e koho i kahimākia huinahaa i ʻole amākēneki pahue like me ka hoʻonohonoho hoʻonohonoho.ʻOiaʻiʻo, i kekahi manawa pono mākou e hana i ke ʻano o ka magnet e like me ke ʻano.Aia kekahi kumu e koi ai e pili ana i ka flux magnet, ʻo ia kā mākou hopohopo i ka koho magnet.ʻO ka ʻoiaʻiʻo, pono mākou e loiloi iā ia ma nā ʻaoʻao ʻelua:
1. E hōʻailona maopopo ʻia ka ikaika o ke kahua mākēneki i hoʻokomo ʻia e ka mea ʻike kūlana o ke keʻena ponoʻī a me ka laulā o ke kahua magnetic i kēlā me kēia ʻaoʻao.
2. Hoʻoholo ʻia ka mamao ma waena o ka magnet a me ka sensor ponoʻī e ke ʻano huahana.E like me nā ʻaoʻao ʻelua i luna a me ka hoʻololi ʻana o ka pihi magnetic i ke kiʻi ma lalo nei ma ke ʻano he laʻana, hiki iā mākou ke hoʻoholo i ka ikaika o ke kahua magnetic o ka magnet koi.
ʻO ka mea hope loa, pono mākou e hoʻomaopopo ʻaʻole ia he manaʻo ʻoiai ka lōʻihi o ka hāʻule ʻana o ke kahua magnetic i nā koi o ka sensor, hiki i ka magnet ke mamao loa mai ka sensor.ʻOiai ʻo ka sensor ponoʻī he hana calibration, pono mākou e hoʻomaopopo i ka wā e mamao loa ka magnet mai ka sensor, paʻakikī ka hāʻawi ʻana o ka māla magnetic ponoʻī e hōʻoia i ka linearity a kokoke i ka linearity.'O ia ho'i, me ka ho'ololi 'ana i ke kūlana a me ka ho'oka'awale 'ole o ke kahua magnetic pono'ī, e lilo ke ana 'ana i mea pa'akikī a pa'akikī loa ka calibration, no laila 'a'ole e ho'emi ka huahana.
ʻO ka mea i luna nei he loiloi maʻalahi o ka koho magnet i nā noi sensor Hall.Manaʻo mākou e kōkua ia iā ʻoe.Inā he mau nīnau ʻē aʻe kāu i ka wā o ka hoʻomohala ʻana, e ʻoluʻolu e kelepona mai iā mākou,ʻO Ningbo Horizon Magnetics.Hiki iā mākou ke kamaʻilio hou a hāʻawi iā ʻoe i ke kākoʻo ʻenehana.
