Air core coil
Ubume obungundoqo kunye nokwakheka
Izinto zocingo:ngokuqhelekileyo ucingo lobhedu okanye i-aluminium (ukuchasana okuphantsi, ukuqhuba okuphezulu), umphezulu unokuthi ube nesilivere okanye ufakwe ngepeyinti yokukhusela.
Indlela yokuphelisa:i-spiral winding (i-single okanye i-multi-layer), imilo ingaba yi-cylindrical, i-flat (i-coil ye-PCB) okanye i-ring.
Uyilo olungenasiseko:i-coil igcwele umoya okanye i-non-magnetic support material (efana nesakhelo seplastiki) ukuphepha ukulahleka kwe-hysteresis kunye nesiphumo sokugcwalisa okubangelwa yintsimbi yentsimbi.
Iiparamitha eziphambili kunye nokusebenza
I-Inductance:ngaphantsi (xa kuthelekiswa neekhoyili zentsimbi), kodwa inokunyuswa ngokunyusa inani lokujika okanye indawo yekhoyili.
Umgangatho womgangatho (ixabiso le-Q):Ixabiso le-Q liphezulu kwii-frequencies eziphezulu (akukho lahleko ye-iron core eddy yangoku), ifanelekile kwizicelo zerediyo (RF).
Umthamo osasaziweyo:I-coil turn-to-turn capacitance inokuchaphazela ukusebenza kwe-high-frequency, kwaye izithuba ezijikelezayo kufuneka ziphuculwe.
Ukuchasa:Ukumiselwa kwezinto zocingo kunye nobude, ukuxhathisa kwe-DC (DCR) kuchaphazela ukusetyenziswa kwamandla.
Izinto eziluncedo nezingeloncedo
Izinto eziluncedo:
Ukusebenza okugqwesileyo okuphezulu-frequency: akukho lahleko yentsimbi, ilungele iRF kunye neesekethe ze-microwave.
Akukho saturation yamagnetic: inductance ezinzileyo phantsi kwangoku ephezulu, ifanelekile kwi-pulse kunye neemeko eziphezulu ezinamandla.
I-Lightweight: isakhiwo esilula, ubunzima obulula, ixabiso eliphantsi.
Izinto ezingeloncedo:
I-inductance ephantsi: ixabiso le-inductance lincinci kakhulu kuneekhoyili zentsimbi kwivolumu efanayo.
Amandla omhlaba wemagnethi abuthathaka: kufuna ujiko olukhulu lwangoku okanye ngaphezulu ukuvelisa umhlaba ofanayo wemagnethi.
Iimeko zosetyenziso oluqhelekileyo
Iisekethe eziphezulu zamaza:
I-RF choke, i-LC resonant circuit, i-eriyali ehambelana nenethiwekhi.
Iinzwa kunye nobhaqo:
Izixhobo zokujonga isinyithi, ii-sensor zangoku ezingaqhagamshelwanga (i-Rogowski coils).
Izixhobo zonyango:
Iikhoyili zegradient kwiinkqubo zeMRI (ukuphepha ukuphazamiseka kwamagnetic).
Ii-elektroniki zamandla:
I-high frequency transformers, iikhoyili zokutshaja ezingenazintambo (ukuphepha ukufudumeza kwe-ferrite).
Iinkalo zophando:
Iikhoyili zeHelmholtz (ukuvelisa iindawo ezifanayo zemagnethi).
FAQ
A: Singumzi mveliso.
A: Sineminyaka engama-20 yamava okuvelisa entwasahlobo kwaye sinokuvelisa iintlobo ezininzi zemithombo. Ithengiswa ngexabiso eliphantsi kakhulu.
A: Ngokubanzi iintsuku ezi-5-10 ukuba iimpahla zikhoyo. Iintsuku ezi-7-15 ukuba iimpahla azikho kwisitokhwe, ngobuninzi.
