Hall mīkiniʻimi

Ke Hall kanawai o ke kumu no ka hoʻohanaʻana i na loea no ole-hui ke kau helu keleponaʻana pae o ka kokekau, ka hele a me ka mämä holo o ka kuapo o ferromagnetic mea.

He aha ka ka Hall mīkiniʻimi, e mea hiki ke hoomaopopo, e ike i keʻano o ka hanaʻana hookoia 'ia i loko o laila. I ka manawa o ka hooholo ana o ka pono ma ka una honua kino i loko o ka lonikū ala e hiki aku ia i kaʻume mākenēki ke kahua ia lŘlŘ i ka hopena haʻawina o ka una honua i loko o ke ala e hiki aku transverse i kaʻikena neʻe, kekahi ikehu like ua hana. Ua ua kena ae la ma ke Lorentz kānāwai, a hoʻokau i ka mea i aie ai i ka aoao o ka meaʻume mākenēki kula tokonositeli kamaʻilioʻana i ka hoʻololi i nā kihi o ka una honua. Ke kūponoʻiaʻana ma ka pololei hapaʻauhau i ka nui o ka maʻi lele huina hoonui o ka kahua ikaika a me kaʻikena H • I.

I ka wa e kaawale aku oʻume mākenēki ke kahua ma ka huina'ine koko, aole ia e ana ei. Ka wā iʻume mākenēki kahua Lorentz koa a komo i loko o ka rejection o na electrons a me ka mea, anuenue o ko lākou mau trajectories. Mau alanui i ka kumu o ka hoʻomāhuahua o ka hopena maikaʻi 'āhewa' ana ma kekahiʻaoʻao o ka una honua. Ke kuʻaoʻao o ka una honua lawelawe 'ana me ke kahua o ka hoʻomāhuahua o ka uncompensated maikaʻi kauoha. I ka lehulehu o ka 'āhewa' ana ma luna o ka ili o ke ku pono maka o ka papa o ke kumu o ka uila kula i loko o ka transverse kuhikuhi, a i kapaia ka Hall kula. Ke kaʻina hanaʻana a hiki i ka malama ana pūnaewele a e hōʻike 'transverse EMF ole compensate no na koa a i ua loaʻa ma kaʻume mākenēki kahua. A laila, lele akula wahi kaʻina 'ano, i ka i electrons hoʻoneʻe i loko o ka laua olelo ana me na kihi o ka papa, e like me ia ma ka wa e kaawale aku oʻume mākenēki kahua.

Hall mīkiniʻimi, e pono

Ka mea uholo uilaʻia o ka Hall mīkiniʻimi no e ua hanaʻia, ke lawe e ia kiʻekiʻe ole wale, akā, e like me ka mea uuku e like me ka hiki kalele iho ma luna o nā aiee o ka mahana, ikeia like me ka Hall kaʻi lau waiwai, a me ka neʻe maila nā nā moku halihali mokulele hiki. No ka koho o ka mea uholo uilaʻia (ka pale kaua - e e ka Hall mīkiniʻimi) e alakai ai kona wahi o ka hana.

Ka Hall kaʻi lau waiwai ua ho'ākāka 'ia ma ka pono no ka ana o kaʻume mākenēki kahua hoʻokomo, i ka pono ma ka hāpana a me ka mea i kona mānoanoa. Me ka ike ana o ka waiwai o ka Hall kaʻi lau waiwai, he mea hiki, e hookupaa aku i ka lehulehu o ka uku ole nā moku halihali mokulele i loko o ke kino o ka papa, i mea inversely hapaʻauhau i ka huina hoonui o ka Hall kaʻi lau waiwai o ka huina'ine kauoha.

Semiconductors i ana pili i ke alo o ka lolouila conduction aie i ka mea i ka mea, i nui kiekie ae lawe ka hoʻoneʻe ma mua o kēlā mau semiconductors i ho'āʻo pa-type conductivity. Mai poina i ka ike i ka physical waiwai o ka mea uholo uila lako hiki e paha i ka mea hou i, ke kaumaha ma muli mea a me ke ano ehia na impurities e e hoʻolauna i loko o ia mau mea.

Hall mīkiniʻimi enehana no ka manufacturing

E hana i kekahi mea uholo uila papaberena hookahi no ka hana i loko o ka Hall mīkiniʻimi hiki e like penei:

1. Hall inu aniani papa i ka makemake kinona o ka hookahi aniani hookolokolo.

2. E kiʻi i ka Hall papa a hiki i ka kūpapakū ma kaʻawa i ka thinnest papa o ka mea uholo uila mea.

Laulā Hall nā mea e loaʻa ka mea nalo

E ho ohana i laina Hall nā mea e loaʻa ka mea nalo e hoʻomano māhele aku i loko o ka palapala:

-ʻikena nā mea e loaʻa ka mea nalo;

- actuators me ka ee iaaanu aey māmā holo;

- hooponopono i puhi ai a me ka 'ohana ka palekana Hawaii;

- wahi nā mea e loaʻa ka mea nalo;

- pele nā mea e loaʻa ka mea nalo;

- Hawaii brushless DC ;

- contactless potentiometers;

- kuapo makau mīkiniʻimi;

- detectors ferromagnetic kino;

- kamakawiwo ole nā mea e loaʻa ka mea nalo;

- tachometer.

Information hookuu aku la i loko o ka pauku, e e kōkua ai i ka mea heluhelu i loko o ka hanana o ke kūkā ma ka mea he Hall mīkiniʻimi.
