Itandukaniro rinini cyane hagati yumuriro wa magneti udasubirwaho na generator ishimishije nuko umurima wacyo wa electromagnetique ukorwa na magneti maremare.Imashini idasubirwaho ni umutungo wa magneti kandi ni igice cyingenzi cyumuzunguruko muri moteri yamashanyarazi.Imiterere ya rukuruzi ya magneti maremare ntabwo ijyanye gusa nuburyo bwo gukora uruganda rutanga umusaruro, nyamara nanone bijyanye nubunini nuburyo imiterere ya rukuruzi idasubirwaho, ubushobozi bwa magnetiseri na tekinike ya magnetisme, ndetse namakuru yihariye yimikorere. ni ubushishozi cyane.Byongeye kandi, imbaraga za rukuruzi hamwe numuvuduko wa magnetomotive imbaraga za magneti zigihe kirekire zishobora gutanga muri moteri nazo ziratandukana nibintu byo guturamo cyangwa ubucuruzi, ibipimo kimwe nibibazo bya moteri ikora amashanyarazi asigaye yumuzunguruko.Ikigeretse kuri ibyo, urwego rwumuzunguruko rukuruzi ya rukuruzi ihoraho iratandukanye, uruziga rukuruzi rwa rukuruzi ruragoye cyane, kandi na flux ya magnetique yamenetse ifite igice kinini, kimwe nibicuruzwa bya ferromagnetiki byoroshye kuzuza, kandi na permeance ntabwo ari umurongo.Ibi byose byongera ubuhanga bwikigereranyo cya electromagnetic igereranya ya generator idasubirwaho, kugirango tumenye neza ko ibisubizo bibarwa biri munsi yubwa moteri itanga amashanyarazi.Kubwibyo, igishushanyo mbonera gishya kigomba gushyirwaho, kandi imiterere yumuzunguruko wa rukuruzi kimwe na sisitemu yo kugenzura bigomba kongera gusesengurwa kandi bikanozwa;uburyo bwo gushushanya bugezweho bugomba gukoreshwa, kimwe nisesengura rishya kandi nubuhanga bwo kugereranya bugomba gusuzumwa kugirango hongerwe neza ibishushanyo mbonera;uburyo bwo kwipimisha buhanitse kandi nubukorikori bugomba kwigwa.ubukorikori.
Kugenzura ibibazo
Nyuma yo gukora imashini ndende ya magneti igihe kirekire, irashobora kugumana imbaraga zayo za magneti idafite ingufu ziva hanze, icyakora nayo ituma bigora cyane guhindura no kugenzura umurima wa rukuruzi uturutse hanze.Ibi bigabanya porogaramu zikurikirana za generator zidasubirwaho.Nubwo bimeze bityo ariko, hamwe niterambere ryihuse ryo kugenzura udushya twibikoresho bya elegitoronike nka MOSFET ndetse na IGBTT, imashini itanga amashanyarazi maremare ntabwo ikenera igenzura rya magneti kandi ikenera gusa ingufu ziva mumashanyarazi mugukoresha.Imiterere ikenera guhuza tekinolojiya itatu mishya yibikoresho bya NdFeB, ibikoresho bya elegitoroniki yimbaraga hamwe na microcomputer, kugirango generator idasubirwaho ishobora gukora mubihe bishya.
Gukuba ikibazo gihoraho cya demagnetisation
Niba igishushanyo nogukoresha bidakwiye, generator yamashanyarazi maremare azaba munsi yibikorwa byigisubizo cya armature cyakozwe na inrush iriho cyangwa munsi yinyeganyeza ikomeye ya mashini mugihe ubushyuhe buri hejuru (NdFeB magnet idasubirwaho) cyangwa kugabanuka cyane (ferrite rukuruzi idasubirwaho).Rimwe na rimwe, demagnetisation idasubirwaho, cyangwa gutakaza magnetisiyoneri, birashobora kubaho, bizagabanya imikorere ya moteri yamashanyarazi kimwe no kuyigira ubusa.Kubera iyo mpamvu, birasabwa gukora ubushakashatsi kimwe no gushyiraho uburyo ndetse n’ibikoresho byo gusuzuma umutekano w’umuriro w’ibikoresho bya magneti birebire bikwiranye n’abakora moteri y’amashanyarazi, ndetse no gusuzuma uburyo bwo guhangana na demagnetisiyonike yubwoko butandukanye bwubatswe, kubijyanye no gukurikiza inzira zingana mugihe cyimiterere kandi ikanakora kugirango ikore magnetism ihoraho.Imashini itanga amashanyarazi ntabwo isuka magnetism.
Ikibazo cyo gukoresha amafaranga
Kuberako igipimo kiriho cyibicuruzwa bidasanzwe bya magneti bihoraho biracyafite igiciro cyinshi, ikiguzi cyumubyigano wisi udasubirwaho amashanyarazi asanzwe arenze ayo kubyara amashanyarazi, ariko iyi ntsinzi rwose izishyurwa neza mubikorwa byinshi kimwe nuburyo bwo kubikora moteri.Muburyo buzaza, ukurikije ibihe byihariye byo gukoresha nibisabwa, imikorere ndetse nigiciro bizagereranywa, kandi nogutezimbere urwego hamwe no kunoza uburyo bizakorwa kugirango igabanye umusaruro.Biragaragara ko igiciro cyakoreshejwe mubicuruzwa biri gutezwa imbere kirenze gato ugereranije na generator yibanze, nyamara itsinda ryacu ryizera ko hamwe nibyiza byiyongereye kubintu, ikibazo cyamafaranga kizakemuka neza.Umuyobozi w'ishami rya tekinike rya DELPHI (Delphi) muri Amerika yizera ko: “Abaguzi bibanda ku kiguzi kuri kilowatt.”Amagambo ye yerekana rwose ko isoko ryoguhumeka imashini itanga amashanyarazi igihe kirekire itazahangayikishwa nibibazo byamafaranga.
