Bakeng sa li-aerospace, likoloi, kapa li-automation tsa indasteri, ho sebetsa hantle ha li-motor tse lebelo le holimo ho bohlokoa haholo. Leha ho le joalo, lebelo le phahameng kamehla le fella ka holimomaqhubu a metsiebe ho fella ka tahlehelo ea matla le ho futhumala ho feteletseng, e leng se amang ts'ebetso ea motlakase ha nako e ntse e ea.
Ke ka lebaka lenamakenete ea hona joale ea anti-eddysli fetohile tsa bohlokoa. Limakete tsena li thusa ho laola maqhubu a eddy, ho boloka lienjene li le mocheso le ho sebetsa ka mokhoa o atlehileng haholoanyane—haholo-holo ka har’a li-motor tse nang le matla a khoheli le lienjene tse tsamaisang moea. Sehloohong sena, re tla hlalosa kamoo theknoloji ena e sebetsang kateng le hore na ke hobane'ng ha lihlahisoa tsa“MagnetPower”li loketse ka ho khetheha, ka lebaka la matla a tsona a ho hanyetsa le mocheso o tlaase.
1. The Eddy Currents
Eddy currents e ile ea hlahisoa ke "MagnetPower”litabeng tsa pele).
Ka li-motor tse lebelo le phahameng, joalo ka tse sebelisoang sebakeng sa sefofane kapa li-compressor (Lebelo la Line ≥ 200m / s), maqhubu a eddy a ka fetoha bothata bo boholo. Li theha ka hare ho li-rotor le stators ha matla a khoheli a fetoha ka potlako.
Maqhubu a Eddy ha se tšitiso e nyane feela; li ka fokotsa matla a motlakase 'me li ka baka tšenyo ha nako e ntse e ea. E hlahisoa ka tsela e latelang:
- Mocheso o Feteletseng: Maqhubu a Eddy a hlahisa mocheso, o behang khatello e eketsehileng likarolong tsa motlakase. Mohlala, tahlehelo e sa fetoheng ea makenete ea limakete tse sa feleng NdFeB kapa SmCo e lula e etsahala ka lebaka la mocheso o phahameng.
- Tahlehelo ea Matla: ts'ebetso ea motlakase e fokotsehile hobane matla a ka tsamaisang motlakase a senyeha ho theha maqhubu ana a eddy.
2. Joang Anti-Eddy Current makenete Thusa
Limanete tsa hona joale tsa anti-eddyli etselitsoe ho rarolla bothata bona hang-hang. Ka ho lekanyetsa hore na maqhubu a eddy a hlaha joang le hore na a hlaha hokae, a etsa bonnete ba hore enjene e sebetsa hantle haholoanyane 'me e lula e pholile. Tsela e 'ngoe e sebetsang ea ho thibela maqhubu a eddy ke ho hlahisa limakete ka sebopeho sa lamination. Mokhoa ona o ka senya tsela ea hona joale ea eddy, ebe o thibela maqhubu a maholo, a potolohang ho theha.
3. Ke Hobane'ng ha Likopano tsa MagnetPower Tech li Iketsetse Likoloi tse Phahameng ka ho Fetisisa
Joale, a re ke re qoela ka melemo e itseng eaSetšoantšo sa MagnetPowerlikopano tsa hona joale tsa anti-eddy. Likopano tsena li nepahetse bakeng sa li-motor tse nang le matla a khoheli le li-motor tse tsamaisang moea, tse fanang ka motsoako o matla oa ho hanyetsa, ho hlahisa mocheso o tlase, le bophelo bo eketsehileng ba makoloi.
3.1 Ho hanyetsana ho Phahameng = Tšebeliso e Phahameng ka ho Fetisisa
Limakete tsa hona joale tsa anti-eddy tse ntlafalitsoeng ke "Magnet Power" ke ho sebelisa sekhomaretsi se sireletsang lipakeng tsa limakenete tse arohaneng, li eketsa ho hanyetsa motlakase, ka holimo ho 2MΩ·cm. Hoa khoneha ho senya tsela ea hona joale ea eddy. Ka hona, mocheso ha o bonolo ho hlahisoa. Sena ke sa bohlokoa ka ho khetheha ho li-motors tsa magnetic bearing. Ka ho fokotsa mocheso, limakete tsa MagnetPower li netefatsa hore li-motor li lula li sebetsa hantle ka lebelo le phahameng ntle le kotsi ea ho futhumala ho feta tekano. Hoa tšoana bakeng salienjene tse tsamaisang moea- mocheso o tlase o boloka lekhalo la moea pakeng tsa rotor le stator e tsitsitseng, e leng ntlha ea bohlokoa bakeng sa ho nepahala.

3.2 Phallo e phahameng ea makenete
Limanete li entsoe ka botenya ba 1mm 'me li na le lera le tšesaane haholo la 0.03mm. Sena se boloka molumo oa sekhomaretsi o le monyane mme molumo oa limakete o le moholo ka moo ho ka khonehang.
3.3 theko e tlase
Ts'ebetso ena e boetse e theola litlhoko le litšenyehelo tsa coercivity ha e ntse e matlafatsa botsitso ba mocheso, Haholo-holo bakeng sa limatlase tsa NdFeB. Haeba mocheso oa rotor o ka fokotsoa ho tloha ho 180 ℃ ho ea ho 100 ℃, Mokhahlelo oa makenete o ka fetoloa ho tloha ho EH ho ea ho SH. Sena se bolela hore litšenyehelo tsa limakete li ka fokotsoa ka halofo.
4. Limanete tsa MagnetPower li sebetsa joang ho High-Speed Motors
Ha re shebeng boits'oaro ba limmanete tsa hona joale tsa MagnetPower tse khahlanong le eddy ho li-motor tse nang le matla a khoheli le li-motor tse nang le moea.
4.1 Magnetic Bearing Motors: Ho tsitsa ka lebelo le phahameng
Ho li-motor tse nang le matla a khoheli, li-magnetic bearing li boloka rotor e emisitsoe, e e lumella ho potoloha ntle le ho ama likarolo tse ling. Empa ka lebaka la matla a phahameng (ho feta 200kW) le lebelo le phahameng (ho feta 150m/s, kapa ho feta 25000RPM), motlakase oa eddy ha o bonolo ho o laola. Setšoantšo sa 2 se bontša rotor e nang le lebelo la 30000RPM. Ka lebaka la tahlehelo e feteletseng ea hona joale ea eddy, mocheso o moholo o ile oa hlahisoa, oa etsa hore rotor e be le mocheso o phahameng oa ho feta 500 ° C.
Limanete tsa MagnetPower li thusa ho thibela sena ka ho fokotsa sebopeho sa hajoale sa eddy. Mocheso oa rotor o ntlafetseng ha oa ka oa feta 200 ℃ boemong bo tšoanang ba ho sebetsa.3
Fig.2 rotor ka mor'a teko ka lebelo la 30000RPM.
4.2 Air Bearing Motors: Ho nepahala ka Lebelo le Phahameng
Li-motor tse tsamaisang moea li sebelisa filimi e tšesaane ea moea e hlahisoang ke ho potoloha ka lebelo le phahameng ho tšehetsa rotor. Li-motor tsena li etselitsoe ho sebetsa ka lebelo le holimo haholo, esita le ho fihla ho 200,000RPM, ka nepo e makatsang. Leha ho le joalo, maqhubu a eddy a ka senya ka nepo ka ho hlahisa mocheso o feteletseng le ho kena-kenana le lekhalo la moea.
Ka limakete tsa MagnetPower, maqhubu a eddy a fokotsehile, ho bolelang hore koloi e lula e pholile 'me e boloka lekhalo le nepahetseng la moea le hlokahalang bakeng sa lits'ebetso tse sebetsang hantle joalo ka Hydrogen fuel cell compressor le blower.
Qetello
Ha ho tluoa ho li-motor tse lebelo le phahameng, ho fokotsa tahlehelo ea matla le ho laola tlhahiso ea mocheso ke senotlolo sa ho ntlafatsa ts'ebetso le ho lelefatsa nako ea bophelo ea lisebelisoa tsa hau. Ke moo makenete a hona joale a anti-eddy a MagnetPower a kenang teng.
Ka lebaka la ts'ebeliso ea lisebelisoa tse hanyetsanang haholo, meralo e bohlale joalo ka karohano le lamination, 'me ho tsepamisitsoe maikutlo ho fokotsa maqhubu a eddy, likopano tsena li thusa li-motor hore li tsamaee ka mokhoa o pholileng, ka katleho le nako e telele. Hore na e ka har'a li-motor tse nang le matla a khoheli, li-motor tse nang le moea, kapa lits'ebetso tse ling tsa lebelo le holimo, MagnetPower e sutumelletsa meeli ea se ka khonehang ts'ebetsong ea enjene le ho ts'epahala.
