Isingeniso:
Ku-aerospace, izimoto, noma ezishintshayo zezimboni, ukusebenza kahle kwamamotho anesivinini esikhulu kubaluleke kakhulu. Kodwa-ke, isivinini esiphezulu sihlala siholela phezuluimisinga eddybese kuba nomphumela wokulahlekelwa amandla kanye nokushisa ngokweqile, okunomthelela ekusebenzeni kwemoto ngokuhamba kwesikhathi.
Yingakho kei-anti-eddy yamanje uzibuthessebebalulekile. Lawa mazibuthe asiza ukulawula ama-eddy currents, agcine izinjini zishisa futhi zisebenza kahle kakhulu—ikakhulukazi kumamotho kazibuthe athwalayo kanye namamotho aphethe umoya. Kulesi sihloko, sizochaza ukuthi lobu buchwepheshe busebenza kanjani nokuthi kungani imikhiqizo ye“I-MagnetPower”zifaneleka kakhulu, ngenxa yokumelana kwazo okuphezulu kanye nokukhiqizwa kokushisa okuphansi.
1. I-Eddy Currents
I-Eddy currents yethulwa ngu “I-MagnetPower”ezindabeni zangaphambili).
Kumamotho anesivinini esikhulu, njengalawo asetshenziswa ku-aerospace noma kuma-compressor (Isivinini somugqa ≥ 200m/s), ama-eddy currents angaba inkinga enkulu. Zakha ngaphakathi kwama-rotors nama-stators njengoba insimu kazibuthe ishintsha ngokushesha.
Imisinga ye-Eddy ayikona nje ukuphazamiseka okuncane; zinganciphisa ukusebenza kahle kwezimoto futhi zingadala nomonakalo ngokuhamba kwesikhathi. Kuboniswa ngokulandelayo:
- Ukushisa Okudlulele: Imisinga ye-Eddy ikhiqiza ukushisa, okubeka ukucindezeleka okwengeziwe ezingxenyeni zezimoto. Isibonelo, ukulahlekelwa okungenakuhlehliswa kazibuthe odonsa unomphela i-NdFeB noma i-SmCo kuhlala kwenzeka ngenxa yezinga lokushisa eliphezulu.
- Ukulahlekelwa Amandla: ukusebenza kahle kwenjini kwehlisiwe ngenxa yokuthi amandla anganika amandla injini ayamoshwa ekudaleni lawa ma-eddy currents.
2. Indlela Ozibuthe Bamanje Be-Anti-Eddy Abasiza Ngayo
Anti-eddy ozibuthe wamanjezenzelwe ukubhekana ngqo nalolu daba. Ngokukhawulela ukuthi ama-eddy currents akheka kanjani futhi kuphi, aqinisekisa ukuthi injini isebenza kahle kakhulu futhi ihlala ipholile. Enye indlela ephumelelayo yokuvimba ama-eddy currents ukukhiqiza omazibuthe esakhiweni se-lamination. Le ndlela ingakwazi ukuphula indlela yamanje ye-eddy, bese ivimbela imisinga emikhulu, ejikelezayo ukuba yakheke.
3. Kungani Imihlangano ye-MagnetPower Tech Ilungele Izimoto Ezihamba Ngesivinini
Manje, ake singene ezinzuzweni ezithile zeI-MagnetPowerimihlangano yamanje ye-anti-eddy. Le mihlangano ilungele izinjini ezithwala kazibuthe kanye namamotho aphethe umoya, anikezela ngenhlanganisela yokumelana okuphezulu, ukukhiqizwa kokushisa okuphansi, nokwenyuka kwempilo yemoto.
3.1 Ukumelana Okuphezulu = Ukusebenza Okukhulu
Ozibuthe bamanje be-anti-eddy abathuthukiswe "Amandla Kazibuthe" ukusebenzisa ingcina yokufaka insulating phakathi kwezingqimba zozibuthe abahlukanisiwe, bandisa ukumelana nogesi, ngaphezu kuka-2MΩ·cm. Kusebenza kahle ukuphula indlela yamanje ye-eddy. Ngakho-ke, ukushisa akulula ukukhiqizwa. Lokhu kubaluleke kakhulu kuma-motor magnetic bearing. Ngokunciphisa ukushisa, omagnethi beMagnetPower baqinisekisa ukuthi izinjini ziqhubeka nokusebenza kahle ngesivinini esiphezulu ngaphandle kwengozi yokushisa ngokweqile. Kuyafana forizinjini ezithwala umoya-ukushisa okuphansi kugcina igebe lomoya phakathi kwe-rotor ne-stator lizinzile, okuyiphuzu eliyinhloko lokunemba.

3.2 I-flux ephakeme kazibuthe
Ozibuthe bakhiwe ngogqinsi oluyi-1mm futhi bafaka ungqimba oluncane kakhulu oluyi-0.03mm. Lokhu kugcina ivolumu yeglue incane futhi umthamo wozibuthe mkhulu ngangokunokwenzeka.
3.3 izindleko eziphansi
Le nqubo iphinde yehlise izimfuno zokuphoqelela kanye nezindleko ngenkathi ithuthukisa ukuzinza okushisayo, Ikakhulukazi kozibuthe be-NdFeB. Uma izinga lokushisa le-rotor lingancishiswa lisuka ku-180 ℃ liye ku-100 ℃, Ibanga lamazibuthe lingashintshwa lisuka ku-EH liye ku-SH. Lokhu kusho ukuthi izindleko zikamazibuthe zingancishiswa ngesigamu.
4. Ozibuthe beMagnetPower basebenza kanjani kumaMotor anesivinini esikhulu
Ake sibheke ukuziphatha kozibuthe be-MagnetPower bamanje be-anti-eddy kumamotho kazibuthe aphethe kanye namamotho aphethe umoya.
4.1 I-Magnetic Bearing Motors: Ukuzinza ngesivinini esikhulu
Kumamotho kazibuthe athwalayo, amandla kazibuthe agcina i-rotor imisiwe, eyivumela ukuthi ijikeleze ngaphandle kokuthinta ezinye izingxenye. Kodwa ngenxa yamandla aphezulu (ngaphezu kuka-200kW) kanye nesivinini esikhulu (ngaphezu kuka-150m/s, noma ngaphezulu kuka-25000RPM), i-eddy current akulula ukuyilawula. I-Fig.2 ibonisa i-rotor enesivinini se-30000RPM. Ngenxa yokulahlekelwa okwedlulele kwamanje kwe-eddy, kuye kwakhiqizwa ukushisa okukhulu, okwenza i-rotor ithole izinga lokushisa eliphezulu elingaphezu kuka-500°C.
Ozibuthe beMagnetPower basiza ukuvimbela lokhu ngokunciphisa ukwakheka kwamanje kwe-eddy. Ukushisa kwe-rotor ethuthukisiwe akuzange kudlule i-200℃ esimweni esifanayo sokusebenza.3

4.2 Ama-Air Bearing Motors: Ukunemba ngesivinini esikhulu
Izinjini ezithwala umoya zisebenzisa ifilimu elincanyana lomoya elikhiqizwa ukuzungezisa ngesivinini esikhulu ukusekela i-rotor. Lawa ma-motor aklanyelwe ukusebenza ngesivinini esikhulu kakhulu, aze afike ku-200,000RPM, ngokunemba okuyisimangaliso. Kodwa-ke, ama-eddy currents angamosha lokho kunemba ngokudala ukushisa okudlulele futhi aphazamise igebe lomoya.
Ngozibuthe be-MagnetPower, imisinga ye-eddy iyancishiswa, okusho ukuthi injini ihlala ipholile futhi igcina igebe eliqondile lomoya elidingekayo ekusebenzeni okuphezulu kwezinhlelo zokusebenza ezifana ne-Hydrogen fuel cell compressor ne-blower.
Isiphetho
Uma kukhulunywa ngamamotho anesivinini esikhulu, ukunciphisa ukulahleka kwamandla nokulawula ukukhiqizwa kokushisa kuyisihluthulelo sokuthuthukisa ukusebenza nokwelula isikhathi sokuphila semishini yakho. Kulapho omagnethi bamanje be-anti-eddy be-MagnetPower bangena khona.
Ngenxa yokusetshenziswa kwezinto ezimelana kakhulu, amadizayini ahlakaniphile afana nokuhlukaniswa kwezigaba kanye ne-lamination, nokugxila ekwehliseni ama-eddy currents, lezi zinhlanganisela zisiza izinjini zisebenze ngokupholile, ngempumelelo kakhudlwana, futhi isikhathi eside. Kungakhathaliseki ukuthi izinjini ezithwele kazibuthe, izinjini eziphethe umoya, noma ezinye izinhlelo zokusebenza ezinesivinini esikhulu, i-MagnetPower icindezela imingcele yalokho okungenzeka ekusebenzeni kahle kwezimoto nokuthembeka.
