1. Ukwethulwa kwenjini enesivinini esikhulu

Amamotho anesivinini esikhulu ngokuvamile abhekisela kumamotho anesivinini esingaphezu kuka-10,000 r/min.I-motor enesivinini esikhulu incane ngosayizi futhi ingaxhunyaniswa ngokuqondile nemithwalo yesivinini esikhulu, isuse isidingo samadivayisi wendabuko okwandisa isivinini semishini, ukunciphisa umsindo wesistimu nokuthuthukisa ukusebenza kahle kokudluliswa kwesistimu.Njengamanje, okuyinhloko okufinyelele isivinini esikhulu ngempumelelo ama-induction motors, ama-motor kazibuthe ahlala njalo, nama-switched reluctance motors.

Izici eziyinhloko zama-motor anesivinini esiphezulu isivinini se-rotor, imvamisa ephezulu ye-stator winding current kanye ne-magnetic flux ku-iron core, ukuminyana kwamandla aphezulu kanye nokulahlekelwa okuphezulu.Lezi zici zinquma ukuthi amamotho anesivinini esikhulu anobuchwepheshe obubalulekile nezindlela zokuklama ezehlukile kulezo zamamotho anesivinini esingaguquki, futhi ubunzima bokuklama kanye nokukhiqiza kuvame ukuphinda kabili kobamamotho anesivinini esijwayelekile.

Izindawo ezisetshenziswayo zamamotho anesivinini esikhulu:

(1) Ama-motor anesivinini esikhulu asetshenziswa ezinhlelweni ezahlukahlukene ezifana nama-centrifugal compressor kuma-air conditioner noma eziqandisini.

(2) Ngokuthuthukiswa kwezimoto eziyingxube embonini yezimoto, amajeneretha anesivinini esikhulu anosayizi omncane nesisindo esincane azokwaziswa ngokugcwele, futhi abe namathemba amahle okusebenza ezimotweni eziyingxubevange, ezondiza, imikhumbi neminye imikhakha.

(3) Ijeneretha enesivinini esikhulu eshayelwa i-turbine yegesi incane ngosayizi futhi inokuhamba okuphezulu.Ingasetshenziswa njengomthombo wamandla oyisipele kwezinye izinsiza ezibalulekile, futhi ingasetshenziswa njengomthombo wamandla ozimele noma isiteshi sikagesi esincane ukuvala ukuntuleka kokuphakelwa kukagesi endaweni eyodwa futhi inenani elibalulekile elingokoqobo.

High-speed unomphela uzibuthe motor

Amamotho kazibuthe ahlala njalo athandwa ezinhlelweni zejubane eliphezulu ngenxa yokusebenza kahle kwawo okuphezulu, amandla aphezulu, kanye nebanga elibanzi lejubane.Uma kuqhathaniswa ne-outer rotor unomphela ozibuthe motor, i-rotor yangaphakathi unomphela ozibuthe motor inezinzuzo ze-rotor radius encane nokuthembeka okuqinile, futhi isibe yisinqumo sokuqala samamotho anesivinini esikhulu.

Njengamanje, phakathi kwezinjini zikazibuthe ezinesivinini esiphezulu ezihlala unomphela ekhaya naphesheya, i-high-speed unomphela uzibuthe motor enamandla aphakeme kakhulu iyacwaningwa e-United States.Amandla angu-8MW kanti ijubane lingu-15000r/min.Kuyi-rotor yamagnetic egibele phezulu.Isembozo sokuzivikela senziwa nge-carbon fiber, futhi uhlelo lokupholisa luthatha Inhlanganisela yokupholisa umoya namanzi isetshenziselwa izinjini zejubane eliphezulu ezihambisana nezinjini zegesi.

I-Swiss Federal Institute of Technology Zurich yakhela injini kazibuthe enesivinini esiphezulu esinesivinini esiphezulu.Amapharamitha angu-500000 r/min, amandla angu-1kW, isivinini somugqa singama-261m/s, kanye nomkhono wokuvikela we-alloy usetshenziswa.

Ucwaningo lwasekhaya lwama-motor kazibuthe anesivinini esikhulu kakhulu lugxile e-Zhejiang University, Shenyang University of Technology, Harbin University of Technology, Harbin Institute of Technology, Xi'an Jiaotong University, Nanjing Aerospace Motor, Southeast University, Beihang University, Jiangsu University, Beijing Jiaotong University, Guangdong University of Technology, CSR Zhuzhou Electric Co., Ltd., njll.

Benza umsebenzi ofanele wocwaningo mayelana nezici zokuklama, izici zokulahlekelwa, amandla e-rotor nokubala kokuqina, ukuklama kwesistimu yokupholisa nokubalwa kokukhuphuka kwezinga lokushisa kwama-motor anesivinini esikhulu, futhi kwakhiqiza ama-prototypes anesivinini esiphezulu namazinga ahlukene wamandla kanye nesivinini.

Izikhombisi-ndlela eziyinhloko zocwaningo nentuthuko zamamotho anesivinini esikhulu yilezi:

Ucwaningo ngezindaba ezibalulekile zamamotho anesivinini esiphezulu kanye nama-ultra-high-speed motors;umklamo wokuhlanganisa osuselwe ku-multi-physics kanye ne-multi-disciplines;ucwaningo lwethiyori kanye nokuqinisekiswa kokuhlolwa kokulahlekelwa kwe-stator ne-rotor;izinto zikazibuthe ezihlala unomphela ezinamandla aphezulu kanye nokumelana nokushisa okuphezulu, ukuqhutshwa kwe-thermal ephezulu Ukuthuthukiswa kanye nokusetshenziswa kwezinto ezintsha ezifana ne-fiber materials;ucwaningo ngezinto ezisezingeni eliphezulu ze-rotor lamination kanye nezakhiwo;ukusetshenziswa kwama-bearings anesivinini esiphezulu ngaphansi kwamazinga ahlukene kanye nesivinini;ukuklanywa kwezinhlelo ezinhle zokushisa ukushisa;ukuthuthukiswa kwezinhlelo zokulawula izimoto ezinesivinini esikhulu;ukuhlangabezana nezidingo zezimboni Ukucutshungulwa kwe-rotor nokuhlanganisa ubuchwepheshe obusha.
