Kungani isivinini semoto sikhuphuka sikhuphuka siqhutshwa yizindleko?

isandulela

 

 

"Engqungqutheleni Yasentwasahlobo ka-2023 ye-Dongfeng Motor Brand" ngo-Ephreli 10, kwakhululwa uhlobo lwamandla olusha lwe-Mach E. U-E umele ugesi, ukusebenza kahle okuphezulu, ukonga amandla kanye nokuvikelwa kwemvelo.I-Mach E yakhiwe ngokuyinhloko izinkundla ezintathu ezinkulu zomkhiqizo: ukushayela kukagesi, ibhethri kanye nesithasiselo samandla.

 

Phakathi kwabo, ingxenye ye-Mach electric drive inezici ezilandelayo:

 

  • I-Motor ene-carbon fibre camera rotor technology, ijubane lingafinyelela ku-30,000 rpm;
  • ukupholisa amafutha;
  • I-flat wire stator ene-slot engu-1 nezintambo ezingu-8;
  • Isilawuli se-SiC esizithuthukisele;
  • Ukusebenza okuphezulu kwesistimu kungafinyelela ku-94.5%.

 

Uma kuqhathaniswa nobunye ubuchwepheshe,i-carbon fiber-coated rotor kanye nesivinini esiphezulu esingu-30,000 rpm kube yizinto ezivelele kakhulu zale drive kagesi.

I-RPM Ephezulu kanye Nezindleko Eziphansi I-Linke Yangaphakathi

Ijubane eliphezulu lemoto yamandla entsha lenyukile lisuka ku-10,000rpm laya kwelejwayelekile elidumile manje elingu-15,000-18,000rpm.Muva nje, izinkampani zethule izinhlelo zokushayela kagesi ezingaphezu kuka-20,000rpm, kungani-ke ijubane lamamotho amandla amasha liya phezulu nangaphezulu?

 

Yebo, imiphumela eqhutshwa yizindleko!

 

Okulandelayo ukuhlaziya ubudlelwano phakathi kwejubane lemoto kanye nezindleko zemoto kumazinga wethiyori kanye nokulingisa.

 

Uhlelo olusha lokushayela ugesi oluhlanzekile luhlanganisa izingxenye ezintathu, injini, isilawuli semoto kanye no-gearbox.Isilawuli se-motor ukuphela kokufaka kwamandla kagesi, i-gearbox iwukuphela kokuphuma kwamandla kagesi, futhi injini iyunithi yokuguqula amandla kagesi namandla kagesi.Indlela yayo yokusebenza ukuthi isilawuli sifaka amandla kagesi (i-voltage yamanje *) enjinini.Ngokusebenzisana kwamandla kagesi namandla kazibuthe ngaphakathi kwemoto, ikhipha amandla emishini (isivinini* torque) ku-gearbox.Ibhokisi legiya lishayela imoto ngokulungisa isivinini kanye nokuphuma kwe-torque ngenjini ngenani lokunciphisa igiya.

 

Ngokuhlaziya ifomula ye-torque ye-motor, kungabonakala ukuthi i-torque T2 ephumayo ye-motor ihlotshaniswa kahle nevolumu ye-motor.

U-N inombolo yokuphenduka kwe-stator, mina ngingumshini wokufakwayo we-stator, B ubuningi be-air flux, R yi-radius ye-rotor core, futhi u-L ubude be-motor core.

 

Endabeni yokuqinisekisa inani lokujika kwemoto, okokufaka kwamanje kwesilawuli, kanye nokuminyana kwegebe lomoya wemoto, uma isidingo se-torque T2 ephumayo yenjini sincishiswa, ubude noma ububanzi bemoto. i-iron core ingancishiswa.

 

Ukuguqulwa kobude be-motor core akubandakanyi ukuguqulwa kwe-stamping die ye-stator ne-rotor, futhi ushintsho lulula, ngakho-ke ukusebenza okuvamile ukucacisa ububanzi bomgogodla nokunciphisa ubude bomgogodla. .

 

Njengoba ubude be-iron core buncipha, inani lezinto ezisebenza ngogesi (i-iron core, insimbi kazibuthe, i-motor winding) liyancishiswa.Izinto ze-electromagnetic zenza ingxenye enkulu yezindleko zemoto, ezibalelwa ku-72%.Uma i-torque ingancishiswa, izindleko zemoto zizoncishiswa kakhulu.

Ukwakhiwa kwezindleko zemoto

 

Ngenxa yokuthi izimoto zamandla amasha zinesidingo esingaguquki se-torque yamasondo, uma i-torque ephumayo yemoto izoncishiswa, isilinganiso sesivinini sebhokisi likagiya kufanele sinyuswe ukuze kuqinisekiswe i-torque yokugcina isondo yemoto.

 

n1=n2/r

T1=T2×r

I-n1 ijubane lokuphela kwesondo, i-n2 ijubane lemoto, i-T1 iyi-torque yesiphetho sesondo, i-T2 iyi-torque ye-motor, futhi r isilinganiso sokunciphisa.

 

Futhi ngenxa yokuthi izimoto ezintsha zamandla zisenesidingo sejubane elikhulu, isivinini esikhulu semoto sizoncipha ngemva kokunyuswa kwesilinganiso sejubane lika-gearbox, okungamukeleki, ngakho-ke lokhu kudinga ukuthi ijubane lemoto likhuphuke.

 

Ngamafuphi,ngemuva kokuthi i-motor inciphise i-torque futhi isheshise, ngesilinganiso sejubane esinengqondo, inganciphisa izindleko zemoto ngenkathi iqinisekisa isidingo samandla emoto.

Umthelela wokusheshisa kwe-de-torsion kwezinye izakhiwo01Ngemuva kokunciphisa i-torque nokusheshisa, ubude be-motor core buyancipha, ingabe kuzothinta amandla? Ake sibheke ifomula yamandla.

U-U yi-voltage yesigaba, mina ngiyi-stator yamanje yokufaka, i-cos∅ iyisici samandla, futhi u-η ukusebenza kahle.

 

Kungabonakala kufomula ukuthi awekho amapharamitha ahlobene nosayizi wenjini kufomula yamandla okukhipha amandla emoto, ngakho-ke ukuguqulwa kobude bomgogodla we-motor kunomphumela omncane emandleni.

 

Okulandelayo umphumela wokulingisa wezimpawu zangaphandle zenjini ethile. Uma kuqhathaniswa nejika lesici sangaphandle, ubude be-iron core buyancishiswa, i-torque ephumayo ye-motor iba yincane, kodwa amandla aphezulu okukhiphayo awashintshi kakhulu, okuqinisekisa nokutholakala okungenhla kwethiyori.

02Ukwanda kwejubane lezimoto kubeka phambili izidingo eziphakeme zokukhethwa kwama-bearings, futhi ama-bearings anesivinini esiphezulu ayadingeka ukuze kuqinisekiswe impilo yokusebenza yama-bearings.

03Ama-motor anesivinini esiphezulu afaneleka kakhulu ukupholisa uwoyela, angasusa inkathazo yokukhetha uphawu lwamafutha ngenkathi eqinisekisa ukushabalaliswa kokushisa.

04Ngenxa yejubane eliphezulu lemoto, kungabhekwa ukusebenzisa injini yocingo oluyindilinga esikhundleni semoto yocingo oluyisicaba ukuze kuncishiswe ukulahleka kwe-AC kokusonteka ngesivinini esikhulu.

05Lapho inani lezigxobo zezimoto lilungisiwe, imvamisa yokusebenza yemoto iyanda ngenxa yokwanda kwejubane. Ukuze unciphise ama-harmonics amanje, kuyadingeka ukwandisa imvamisa yokushintsha yemodyuli yamandla. Ngakho-ke, isilawuli se-SiC esinokumelana okuphezulu kokushintsha imvamisa singuzakwethu omuhle wamamotho anesivinini esikhulu.

06Ukuze unciphise ukulahleka kwe-iron ngesivinini esikhulu, kuyadingeka ukucabangela ukukhethwa kokulahlekelwa okuphansi kanye nezinto eziphezulu ze-ferromagnetic.

07Qinisekisa ukuthi i-rotor ayikwazi ukonakala ngenxa yesivinini eseqile izikhathi ezingu-1.2 isivinini esiphezulu, njengokwenza kahle kwebhuloho lokuhlukanisa kazibuthe, i-carbon fibre coating, njll.

Ukwenyuka kwesivinini semoto kungasindisa izindleko zemoto, kodwa ukukhuphuka kwezindleko kwezinye izakhi nakho kudinga ukucatshangelwa ngokulingana.Ama-motor anesivinini esikhulu azoba isiqondiso sokuthuthukiswa kwezinhlelo zokushayela ugesi. Lena akuyona nje indlela yokonga izindleko, kodwa futhi ukubonakaliswa kwezinga lobuchwepheshe lebhizinisi.Ukuthuthukiswa nokukhiqizwa kwama-motor anesivinini esikhulu kusenzima kakhulu. Ngaphezu kokusetshenziswa kwezinto ezintsha nezinqubo ezintsha, kudinga nomoya wobungcweti bonjiniyela bakagesi.
