Why is the speed of the motor getting higher and higher driven by cost?

Intshayelelo

Kwi-"2023 Dongfeng Motor Brand Spring Conference" nge-10 ka-Epreli, i-Mach E yamandla ombane entsha yakhululwa.U-E umele umbane, ukusebenza kakuhle kakhulu, ukonga umbane kunye nokukhuselwa kwendalo.IMach E ikakhulu yenziwe ngamaqonga amathathu emveliso: ukuqhuba kombane, ibhetri kunye nokongeza amandla.

Phakathi kwabo, inxalenye ye-Mach electric drive ineempawu ezilandelayo:

Imoto ene-carbon fiber coated rotor technology, isantya sinokufikelela kwi-30,000 rpm;
ukupholisa ioli;
I-Flat wire stator ene-1 slot kunye neengcingo ezi-8;
Umlawuli weSiC oziphuhlisileyo;
Ukusebenza okuphezulu kwenkqubo kunokufikelela kwi-94.5%.

Xa kuthelekiswa nezinye itekhnoloji,i-carbon fiber-coated rotor kunye nesantya esiphezulu se-30,000 rpm ibe yizona zinto zibalaseleyo ezibalaseleyo zolu kuqhuba kombane.

Mach E 30000rpm drive yombane

I-RPM ephezulu kunye neNdleko ePhantsi ye-Intrinsically Linkke

Esona santya siphezulu semoto yamandla entsha sinyukile ukusuka kwi-10,000rpm yokuqala ukuya kwi-15,000-18,000rpm ngoku eyaziwa ngokubanzi.Kutshanje, iinkampani ziqalise ngaphezulu kwe-20,000rpm iinkqubo zokuqhuba umbane, kutheni ke isantya seenjini zamandla amatsha sinyuka nangaphezulu?

Ewe, iziphumo eziqhutywa yindleko!

Oku kulandelayo luhlalutyo lobudlelwane phakathi kwesantya semoto kunye neendleko zemoto kwinqanaba lethiyori kunye nokulinganisa.

Inkqubo yamandla amatsha acocekileyo okuqhuba umbane ngokubanzi ibandakanya iinxalenye ezintathu, i-motor, isilawuli semoto kunye nebhokisi yegiya.Isilawuli semoto sisiphelo segalelo lamandla ombane, ibhokisi yegiya sisiphelo samandla oomatshini, kwaye imotor yiyunithi yokuguqula amandla ombane kunye namandla oomatshini.Indlela yayo yokusebenza kukuba umlawuli ufaka amandla ombane (okhoyo * ombane) kwimoto.Ngokudibana kwamandla ombane kunye namandla kazibuthe ngaphakathi kwimotor, ikhupha amandla oomatshini (isantya * torque) kwibhokisi yegiya.Ibhokisi yegiya iqhuba isithuthi ngokulungelelanisa isantya kunye ne-torque ephumayo yimoto ngomlinganiselo wokunciphisa igiya.

Ngokuhlalutya ifomyula ye-motor torque, kunokubonwa ukuba i-torque ye-T2 ye-motor ephumayo idityaniswa ngokufanelekileyo kunye nomthamo wemoto.

I-N linani lokujika kwe-stator, mna igalelo langoku le-stator, B yi-air flux density, R yi-radius ye-rotor core, kunye no-L ubude be-motor core.

Kwimeko yokuqinisekisa inani lokujika kwemoto, igalelo langoku lomlawuli, kunye noxinaniso lwe-flux ye-gap yomoya wemoto, ukuba imfuno ye-torque T2 ye-motor iyancitshiswa, ubude okanye ububanzi be-motor. undoqo wentsimbi unokuncitshiswa.

Ukutshintsha ubude be-motor core ayibandakanyi utshintsho lwe-stamping die ye-stator kunye ne-rotor, kwaye utshintsho lulula, ngoko ke umsebenzi oqhelekileyo kukumisela ububanzi be-core kunye nokunciphisa ubude be-core. .

Njengoko ubude bombindi wentsimbi buncipha, ubungakanani bezinto zombane (undoqo wentsimbi, intsimbi yemagnethi, imotor winding) iyancitshiswa.Izixhobo ze-electromagnetic zichaza umlinganiselo omkhulu weendleko zemoto, ezibalelwa malunga ne-72%.Ukuba i-torque ingancitshiswa, iindleko zemoto ziya kuncitshiswa kakhulu.

Ukwakhiwa kweendleko zeMoto

Ngenxa yokuba iimoto zamandla amatsha zinemfuno esisigxina yetorque yokuphela kwevili, ukuba itorque yemoto iza kuncitshiswa, umlinganiselo wesantya sebhokisi yegiya kufuneka unyuswe ukuqinisekisa ukuba ivili letorque yesithuthi.

n1=n2/r

T1=T2×r

I-n1 yisantya sokuphela kwevili, i-n2 yisantya se-motor, i-T1 yi-torque yesiphelo sevili, i-T2 yi-torque ye-motor, kunye ne-r yi-reyishini yokunciphisa.

Kwaye ngenxa yokuba iimoto zamandla amatsha zisenemfuno yesantya esiphezulu, isantya esiphezulu sesithuthi siya kuncipha emva kokuba umlinganiselo wesantya sebhokisi yegiya lonyusiwe, into engamkelekanga, ngoko oku kufuna ukuba isantya semoto sinyuswe.

Ukushwankathela,emva kokuba i-motor inciphisa i-torque kunye nesantya, kunye nomlinganiselo wesantya esifanelekileyo, inokunciphisa iindleko zemoto ngelixa iqinisekisa imfuno yamandla esithuthi.

Impembelelo yesantya sokususwa kwe-torsion kwezinye iipropathi01Emva kokunciphisa i-torque kunye nokukhawuleza, ubude be-motor core buyancipha, ngaba kuya kuchaphazela amandla?Makhe sijonge kwifomula yamandla.

U-U yi-voltage yesigaba, mna i-stator input yangoku, i-cos∅ yinto yamandla, kwaye η kukusebenza kakuhle.

Inokubonwa kwifomula ukuba akukho parameters ezinxulumene nobukhulu bemoto kwifomula yamandla ombane wokukhupha amandla, ngoko ke ukuguqulwa kobude besiseko semoto kunempembelelo encinci kumandla.

Oku kulandelayo sisiphumo sokulinganisa iimpawu zangaphandle zemoto ethile.Xa kuthelekiswa nejiko lophawu lwangaphandle, ubude bombindi wentsimbi buyancitshiswa, i-torque ephumayo yemoto iba yincinci, kodwa amandla aphezulu aphumayo awatshintshi kakhulu, nto leyo eqinisekisa ukuvela kwethiyori engentla.

Ukuthelekiswa kweegophe zeempawu zangaphandle zamandla emoto kunye netorque enobude obuhlukeneyo bentsimbi

02Ukunyuka kwesantya semoto kubeka phambili iimfuno eziphezulu zokukhethwa kweebheringi, kwaye iibherethi zesantya esiphezulu zifunekayo ukuze kuqinisekiswe ubomi bokusebenza kweebheringi.

03Iinjini ezihamba ngesantya esiphezulu zifaneleke ngakumbi ukupholisa ioli, ezinokususa inkathazo yokukhethwa kwesitywina seoli ngelixa uqinisekisa ukuchithwa kobushushu.

04Ngenxa yesantya esiphezulu se-motor, kunokuqwalaselwa ukusebenzisa i-motor yocingo olujikelezileyo endaweni ye-motor yocingo olusicaba ukunciphisa ilahleko ye-AC yokujikeleza ngesantya esiphezulu.

05Xa inani leepali zemoto lilungisiwe, ukuhamba rhoqo kweemoto kwandisa ngenxa yokunyuka kwesantya.Ukuze kuncitshiswe i-harmonics yangoku, kuyimfuneko ukwandisa ukuphindaphinda kokutshintsha kwemodyuli yamandla.Ke ngoko, isilawuli se-SiC esinokutshintsha okuphezulu kokumelana nokutshintsha liqabane elilungileyo leenjini ezinesantya esiphezulu.

06Ukuze kuncitshiswe ilahleko yentsimbi ngesantya esiphezulu, kuyimfuneko ukuqwalasela ukukhethwa kwelahleko ephantsi kunye namandla aphezulu ezixhobo ze-ferromagnetic.

07Qinisekisa ukuba i-rotor ayinakonakaliswa ngenxa yesantya esiphezulu kwi-1.2 isantya esiphezulu, njengokulungiswa kwebhuloho ye-magnetic isolation, i-carbon fiber coating, njl.

Umfanekiso wokuluka ifayibha yekhabhoni

Shwankathela

Ukunyuka kwesantya semoto kunokonga iindleko zemoto, kodwa ukonyuka kweendleko zamanye amacandelo nako kufuneka kuqwalaselwe ngokulinganisela.Iinjini ezihamba ngesantya esiphezulu ziya kuba ngumkhombandlela wophuhliso lweenkqubo zokuqhuba umbane.Oku akukuphela kwendlela yokugcina iindleko, kodwa kunye nokubonakaliswa kwenqanaba lobugcisa beshishini.Ukuphuhliswa kunye nokuveliswa kweenjini zesantya esiphezulu kusenzima kakhulu.Ukongeza ekusebenziseni izinto ezintsha kunye neenkqubo ezintsha, kukwafuna umoya wokugqwesa kweenjineli zombane.
