Intshayelelo:
Kwi-aerospace, i-automotive, okanye i-automation ye-industrial, ukusebenza kakuhle kweenjini ezinesantya esiphezulu kubaluleke kakhulu. Nangona kunjalo, isantya esiphezulu sihlala sikhokelela phezuluimisinga eddykwaye emva koko kubangele ilahleko yamandla kunye nokufudumeza, okuchaphazela ukusebenza kwemoto ngokuhamba kwexesha.
Kunjalo ngobaumazibuthe wangoku anti-eddysziye zabaluleka. Ezi magnethi zinceda ukulawula imisinga yeeddy, ukugcina iimotor zishushu kwaye zisebenza ngokufanelekileyo-ingakumbi kwiimotor ezithwala imagnethi kunye neemotor ezithwala umoya. Kweli nqaku, siza kuchaza ukuba le teknoloji isebenza njani kwaye kutheni iimveliso ze“IMagnetPower”zifaneleke ngokukodwa, ngenxa yokumelana kwazo okuphezulu kunye nesizukulwana sobushushu obuphantsi.
1. I-Eddy Currents
Eddy imisinga yaziswa ngu "IMagnetPower”kwiindaba zangaphambili).
Kwiimoto ezihamba ngesantya esiphezulu, njengalezo zisetyenziselwa i-aerospace okanye i-compressors (Isantya somgca ≥ 200m / s), i-eddy currents ingaba yingxaki enkulu. Benza ngaphakathi kwee-rotors kunye ne-stators njengoko i-magnetic field itshintsha ngokukhawuleza.
Imisinga ye-Eddy ayiyongxaki nje encinci; banokunciphisa ukusebenza kwemoto kwaye banokubangela nomonakalo ekuhambeni kwexesha. Iboniswe ngokulandelayo:
- Ubushushu obugqithisileyo: Imisinga ye-Eddy ivelisa ubushushu, obubeka uxinzelelo olongezelelweyo kwiindawo zemoto. Umzekelo, ilahleko yemagnethi eNgabuyiselekiyo yeemagnethi ezisisigxina i-NdFeB okanye i-SmCo ihlala isenzeka ngenxa yobushushu obuphezulu.
- Ilahleko yaMandla: ukusebenza kakuhle kwemoto kuye kwehliswa ngenxa yokuba amandla anokuthi anike amandla imotor ayachithwa ekudaleni le misinga yeeddy.
2. Uncedo lwemagnethi yangoku yeAnti-Eddy
Anti-eddy imagnethi yangokuziyilelwe ukujongana ngqo nalo mba. Ngokunciphisa indlela kunye nendawo eyenzeka ngayo imisinga ye-eddy, baqinisekisa ukuba i-motor iqhuba ngokufanelekileyo kwaye ihlala ipholile. Enye indlela esebenzayo yokuthintela imisinga yeeddy kukuvelisa iimagnethi kwisakhiwo se-lamination. Le ndlela inokwaphula indlela yangoku ye-eddy, kwaye emva koko inqande imisinga emikhulu, ejikelezayo ukuba yenze.
3. Kutheni ii-Assemblies zeMagnetPower Tech zifanelekile kwiiMoto eziPhezulu
Ngoku, makhe sintywizise kwiingenelo ezithile zeI-MagnetPower'siindibano zangoku ezichasene ne-eddy. Ezi ndibano zifanelekile kwiinjini ezithwele imagnethi kunye neemotor ezithwele umoya, zibonelela ngokudityaniswa kokumelana okuphezulu, ubushushu obuphantsi, kunye nokwanda kobomi bemoto.
3.1 Ukuxhathisa okuphezulu = Ukusebenza okuphezulu
Iimagnethi zangoku ezichasene ne-eddy eziphuhliswe yi "Magnet Power" kukusebenzisa i-insulating glue phakathi kweengqimba zeemagnethi eziqhekekayo, zandisa ukuxhathisa kombane, ngaphezu kwe-2MΩ · cm. Kusebenza ngokufanelekileyo ukwaphula indlela yangoku eddy. Ngoko ke, ubushushu akulula ukuveliswa. Oku kubaluleke ngakumbi kwiinjini zokuthwala imagnethi. Ngokunciphisa ubushushu, iimagnethi zeMagnetPower ziqinisekisa ukuba iimotor zihlala zihamba kakuhle ngesantya esiphezulu ngaphandle komngcipheko wobushushu obugqithisileyo. Kuyafana nakwiiinjini zomoya-ubushushu obuphantsi bugcina i-gap yomoya phakathi kwe-rotor kunye ne-stator ezinzile, eyona ngongoma ephambili yokuchaneka.

3.2 Umjikelo wemagnethi ephezulu
Iimagnethi zenziwa ngobukhulu obuyi-1mm kwaye zibonisa umaleko obhityileyo wokugquma oyi-0.03mm. Oku kugcina umthamo weglue omncinci kwaye umthamo wemagnethi mkhulu kangangoko.
3.3 ixabiso eliphantsi
Le nkqubo ikwathoba iimfuno zokunyanzeliswa kunye neendleko ngelixa uphucula uzinzo lwe-thermal, Ngokukodwa kwimagnethi ye-NdFeB. Ukuba ubushushu be-rotor bunokuncitshiswa ukusuka kwi-180 ℃ ukuya kwi-100 ℃, ibakala lemagnethi lingatshintshwa ukusuka kwi-EH ukuya kwi-SH. Oku kuthetha ukuba iindleko zemagnethi zinokucuthwa ngesiqingatha.
4. Iimagnethi zeMagnetPower zisebenza njani kwiiMoto ezikwisantya esiphezulu
Makhe sijonge indlela yokuziphatha kweMagnetPower's anti-eddy yemagnethi yangoku kwiimotor ezinemagnethi kunye neemotor ezithwala umoya.
4.1 I-Magnetic Bearing Motors: Uzinzo kwisantya esiphezulu
Kwiimoto ezithwala imagnethi, imagnethi igcina irotor inqunyanyisiwe, iyivumela ukuba ijikeleze ngaphandle kokuchukumisa naziphi na ezinye iindawo. Kodwa ngenxa yamandla aphezulu (ngaphezu kwe-200kW) kunye nesantya esiphezulu (ngaphezu kwe-150m / s, okanye ngaphezulu kwe-25000RPM), i-eddy current ayilula ukuyilawula. Umfanekiso we-2 ubonisa i-rotor enesantya se-30000RPM. Ngenxa yelahleko egqithisileyo yangoku, ubushushu obukhulu benziwa, obangela ukuba i-rotor ibe nobushushu obuphezulu obungaphezulu kwama-500°C.
Iimagnethi zeMagnetPower zinceda ukuthintela oku ngokunciphisa ukwakheka kwe-eddy yangoku. Ukushisa kwe-rotor ephuculweyo akuzange kudlule i-200 ℃ kwimeko efanayo yokusebenza.3
Umfanekiso we-2 i-rotor emva kovavanyo ngesantya se-30000RPM.
4.2 IiMoto ezithwala umoya: Ukuchaneka kwisantya esiphezulu
Iimotor ezithwala umoya zisebenzisa ifilimu encinci yomoya eveliswa ngokujikeleza ngesantya esiphezulu ukuxhasa i-rotor. Ezi motors ziyilelwe ukusebenza ngesantya esiphezulu kakhulu, ukuya kuthi ga kwi-200,000RPM, ngokuchaneka okumangalisayo. Nangona kunjalo, imisinga ye-eddy inokuphazamisana nokuchaneka ngokuvelisa ubushushu obugqithisileyo kunye nokuphazamisa umsantsa womoya.
Ngoomazibuthe beMagnetPower, imisinga yeeddy iyancitshiswa, nto leyo ethetha ukuba imoto ihlala ipholile kwaye igcina umsantsa womoya ochanekileyo ofunekayo ekusebenzeni okuphezulu kwezicelo ezifana ne-Hydrogen fuel compressor kunye ne blower.
Ukuqukumbela
Xa kuziwa kwiinjini ezinesantya esiphezulu, ukunciphisa ilahleko yamandla kunye nokulawula ukuveliswa kobushushu ngundoqo ekuphuculeni ukusebenza kunye nokwandisa ubomi besixhobo sakho. Kulapho imagnethi ye-anti-eddy yangoku yeMagnetPower ingena khona.
Enkosi kusetyenziso lwezixhobo ezixhathisayo eziphezulu, uyilo olukrelekrele njengokwahlulahlulwa kunye nokwahlulahlula, kunye nokujolisa ekunciphiseni imisinga yeeddy, ezi ndibano zinceda iimotor ukuba zibaleke zipholile, zisebenza kakuhle, kwaye ixesha elide. Nokuba kwiinjini ezithwele imagnethi, iimotor ezithwele umoya, okanye ezinye izinto ezinesantya esiphezulu, iMagnetPower ityhala imida yento enokwenzeka ekusebenzeni kakuhle kwemoto kunye nokuthembeka.
