Umkhombandlela weMagnetization: Ngokwesicelo sakho
I-Magnetic rotor, okanye i-rotor yemagnethi esisigxina yindawo engemiyo yenjini. I-rotor yinxalenye ehambayo kwi-motor yombane, i-generator kunye nokunye. Iirotor zemagneti ziyilwe ngeepali ezininzi. Ipali nganye iyatshintshana kwipolarity (emantla nakumazantsi). Izibonda ezichasayo zijikeleza malunga nendawo ephakathi okanye i-axis (ngokusisiseko, i-shaft iphakathi). Olu luyilo oluphambili lweerotors. I-motor magnetic esisigxina enqabileyo yomhlaba inoluhlu lweenzuzo, ezifana nobukhulu obuncinci, ubunzima obulula, ukusebenza okuphezulu kunye neempawu ezilungileyo. Izicelo zayo zibanzi kakhulu kwaye zanda kuyo yonke imimandla yenqwelomoya, indawo, ukhuselo, ukwenziwa kwezixhobo, imveliso yeshishini kunye nezolimo kunye nobomi bemihla ngemihla.
Ukudityaniswa kweMagnetic ludibaniso olungaqhagamshelwanga olusebenzisa umhlaba wemagnethi ukuhambisa itorque, amandla okanye intshukumo ukusuka kwelinye ilungu elijikelezayo ukuya kwelinye. Udluliselo lwenzeka ngesithintelo esingeso-magnetic esinezithintelo ngaphandle konxibelelwano lwasemzimbeni. I-couplings zimbini ezichasayo zeediski okanye ii-rotors ezifakwe kwiimagnethi.
Injongo yokusika imagnethi yonke ibe ziziqwenga ezininzi kwaye uyisebenzise kunye kukunciphisa ilahleko yeeddi. Sibiza ezi magnethi zinobubele "Lamination". Ngokuqhelekileyo, amaqhekeza amaninzi, ngcono umphumo wokunciphisa ilahleko ye-eddy. I-lamination ayiyi kutshabalalisa ukusebenza kwemagnethi ngokubanzi, kuphela i-flux eya kuchaphazeleka kancinci. Ngokuqhelekileyo silawula izikhewu zeglue ngaphakathi kobunzima obuthile usebenzisa indlela ekhethekileyo yokulawula i-gap nganye inobunzima obufanayo.
Igama leMveliso: Linear Motor Magnet Izinto eziphathekayo: Iimagnethi zeNeodymium / iimagnethi zomhlaba eziRare Ubungakanani: Umgangatho okanye ulungiselelwe Ukwaleka: Isilivere, iGolide, iZinc, iNickel, iNi-Cu-Ni. Ubhedu njl. Ubume: Imagnethi yebhloko ye-Neodymium okanye eyenziwe ngokwezifiso
I-Halbach array sisakhiwo semagnethi, esisisakhiwo esifanelekileyo kubunjineli. Injongo kukuvelisa eyona ndawo inamandla yemagnethi enelona nani lincinci lemagnethi. Ngomnyaka we-1979, xa uKlaus Halbach, umphengululi waseMelika, eqhuba iimvavanyo zokukhawulezisa i-electron, wafumana esi sakhiwo sikhethekileyo samagnetic esisisigxina, saphucula ngokuthe ngcembe esi sakhiwo, kwaye ekugqibeleni wenza into ebizwa ngokuba yi-magnetic "Halbach".
Injini yemagnethi esisigxina ngokubanzi ingahlelwa ngokwemagnethi alternating current (PMAC) motor kunye nemagnethi esisigxina yangoku (PMDC) motor ngokwefomu yangoku. Imoto ye-PMDC kunye ne-PMAC motor inokwahlulwa ngakumbi ukuze ibrashi/i-brushless motor kunye ne-asynchronous/synchronous motor, ngokulandelelanayo. Imincili yemagnethi esisigxina inokunciphisa kakhulu ukusetyenziswa kwamandla kunye nokomeleza ukusebenza kwemoto.
Kukho iindlela ezininzi zokusetyenziswa kweemagnethi ezisisigxina kwizicelo zeemoto, kubandakanya ukusebenza kakuhle. Ushishino lweemoto lugxile kwiindidi ezimbini zokusebenza kakuhle: ukusebenza kakuhle kwamafutha kunye nokusebenza kakuhle kumgca wokuvelisa. Iimagnethi zinceda kuzo zombini.
I-N pole kunye ne-S pole yemagnethi zicwangciswe ngokutshintshanayo. Ipali ye-N enye kunye nepali enye zibizwa ngokuba zipere zeepali, kwaye iimotor zinokuba nazo naziphi na iperi yezibonda. Iimagnethi zisetyenziswa kubandakanya i-aluminiyam nickel cobalt umazibuthe osisigxina, iimagnethi ezisisigxina zeferrite kunye noomazibuthe onqabileyo bomhlaba osisigxina (kubandakanya imagnethi esisigxina yesamarium cobalt kunye neodymium iron boron umazibuthe osisigxina). Umkhombandlela wemagneti wahlulwe kwi-parallel magnetization kunye ne-radial magnetization.
Amandla omoya abe ngowona mthombo wamandla acocekileyo unokwenzeka emhlabeni. Kangangeminyaka emininzi, uninzi lombane wethu beluvela kumalahle, i-oyile kunye nezinye izibaso zefosili. Nangona kunjalo, ukudala amandla kobu butyebi kubangela umonakalo omkhulu kwindawo yethu kwaye kungcolise umoya, umhlaba kunye namanzi. Oku kuqatshelwa kuye kwenza abantu abaninzi baphendukela kumandla aluhlaza njengesisombululo.
Umazibuthe we-neodymium oneqondo eliphantsi lokunyanzeliswa unokuqalisa ukuphulukana namandla ukuba ubushushu obungaphezulu kwe-80°C. Ukunyanzeliswa okuphezulu kwemagnethi ye-neodymium iphuhliswe ukuba isebenze kumaqondo obushushu ukuya kuthi ga kwi-220 ° C, kunye nelahleko encinci engenakubuyiselwa. Imfuno yomlinganiso wobushushu obuphantsi kwizicelo zemagnethi ye-neodymium ikhokelele kuphuhliso lwamabakala amaninzi ukuhlangabezana neemfuno ezithile zokusebenza.
Inxalenye enkulu kunye nebalulekileyo ye-MRI & NMR yimagnethi. Iyunithi echonga eli bakala lamagnetic libizwa ngokuba yiTesla. Enye iyunithi eqhelekileyo yokulinganisa isetyenziswa kwiimagnethi yiGauss (1 Tesla = 10000 Gauss). Okwangoku, iimagnethi ezisetyenziselwa ukucinga nge-magnetic resonance imaging zikuluhlu lwe-0.5 Tesla ukuya kwi-2.0 Tesla, oko kukuthi, i-5000 ukuya kwi-20000 Gauss.
