Mamiriro uye dhizaini yemotokari yemagetsi yakachena yakasiyana neyechinyakare mukati memoto injini inotyairwa. Iyo zvakare yakaoma system engineering. Inoda kubatanidza tekinoroji yebhatiri remagetsi, mota yekutyaira tekinoroji, tekinoroji yemotokari uye yemazuva ano yekudzora dzidziso kuti uwane yakakwana yekudzora maitiro. Muchirongwa chekusimudzira chesainzi yemotokari yemagetsi uye tekinoroji, nyika inoramba ichitevedzera R&D dhizaini ye "matatu akatwasuka uye matatu akatwasuka", uyezve inosimbisa tsvakiridzo payakajairwa tekinoroji ye "matatu akatwasuka" maererano nehunyanzvi hwekushandura tekinoroji. "pure electric drive", ndiko kuti, tsvagiridzo yemotokari yemotokari uye hurongwa hwayo hwekutonga, bhatiri remagetsi nehurongwa hwayo hwekutarisira, uye powertrain control system. Mumwe nemumwe mukuru anogadzira anogadzira nzira yake yekuvandudza bhizinesi zvinoenderana nehurongwa hwenyika hwekusimudzira.
Munyori anoronga matekinoroji akakosha mukuvandudza kwesimba idzva remagetsi, achipa hwaro hwekufungidzira uye referensi yekugadzira, kuyedza, uye kugadzirwa kweiyo powertrain. Urongwa uhwu hwakakamurwa kuita zvitsauko zvitatu zvekuongorora akakosha matekinoroji emagetsi dhiraivha mune powertrain yemotokari dzemagetsi dzakachena. Nhasi, isu tichatanga kusuma musimboti uye kupatsanurwa kwemagetsi ekutyaira matekinoroji.
Mufananidzo 1 Key Links muPowertrain Development
Parizvino, iwo epakati kiyi matekinoroji eiyo yakachena yemagetsi mota powertrain inosanganisira anotevera mapoka mana:
Mufananidzo 2 Iyo Core Key Technologies yePowertrain
Tsanangudzo yeDriving Motor System
Zvinoenderana nechimiro chebhatiri remagetsi emotokari uye zvinodiwa zvesimba remotokari, inoshandura simba remagetsi rinobuda ne-on-board simba rekuchengetedza simba rekugadzira magetsi kuita magetsi emagetsi, uye simba racho rinoendeswa kumavhiri ekutyaira kuburikidza nemudziyo wekufambisa, uye zvikamu. simba remagetsi remotokari rinoshandurwa kuita simba remagetsi uye rinodzoserwa mumudziyo wekuchengetedza simba kana mota ikabhureka. Iyo yemagetsi yekutyaira system inosanganisira mota, transmission mechanism, mota controller uye zvimwe zvinhu. Dhizaini yematekinoroji emagetsi emagetsi ekutyaira system anonyanya kusanganisira simba, torque, kumhanya, voltage, transmission ratio yekudzikisa, magetsi ekupa capacitance, kubuda simba, voltage, ikozvino, nezvimwe.
1) Mota controller
Iyo inonziwo inverter, inoshandura yakananga ikozvino kupinza neiyo simba bhatiri paki kuita inochinjana ikozvino. Core components:
◎ IGBT: simba remagetsi switch, musimboti: kuburikidza nemutongi, dzora IGBT bhiriji ruoko kuti uvhare imwe frequency uye kutevedzana switch kuti igadzire matatu-chikamu chinochinjisa ikozvino. Nekudzora magetsi emagetsi switch kuti avhare, iyo alternating voltage inogona kushandurwa. Ipapo iyo AC voltage inogadzirwa nekudzora kutenderera kwebasa.
◎ Firimu capacitance: kusefa basa; ikozvino sensor: kuona ikozvino kwematatu-chikamu mhepo.
2) Kudzora uye kutyaira redunhu: komputa inodzora bhodhi, kutyaira IGBT
Basa remutongi wemota ndere kushandura DC kuita AC, kugamuchira chiratidzo chega chega, uye kuburitsa simba rinoenderana uye torque. Core components: power electronic switch, film capacitor, current sensor, control drive circuit kuvhura ma switch akasiyana, gadzira macurrents munzira dzakasiyana, uye kugadzira alternating voltage. Naizvozvo, tinogona kupatsanura sinusoidal alternating ikozvino kuita rectangles. Nzvimbo ye rectangles inoshandurwa kuva voltage ine urefu hwakafanana. Iyo x-axis inoziva hurefu hwekutonga nekudzora kutenderera kwebasa, uye pakupedzisira inoona kutendeuka kwakaenzana kwenzvimbo. Nenzira iyi, iyo DC simba inogona kudzorwa kuvhara IGBT bhiriji ruoko pane imwe frequency uye kutevedzana chinja kuburikidza nemutongi kugadzira matatu-chikamu AC simba.
Parizvino, zvikamu zvakakosha zvedunhu redhiraivha zvinotsamira pane zvinotengeswa kunze kwenyika: capacitors, IGBT / MOSFET switch chubhu, DSP, machipisi emagetsi uye maseketi akabatanidzwa, anogona kugadzirwa akazvimirira asi ane husimba husina simba: maseketi akakosha, masensa, majoini, anogona inogadzirwa yakazvimiririra: magetsi emagetsi, diode, inductors, multilayer circuit board, insulated waya, radiators.
3) Mota: shandura-nhatu-chikamu chinochinjisa ikozvino kuita muchina
◎ Chimiro: kumberi uye kumashure ekupedzisira mavhavha, mabhomba, shafts uye mabhengi
◎ Magnetic wedunhu: stator musimboti, rotor musimboti
◎ Dunhu: stator mhepo, rotor conductor
4) Kutumira Chishandiso
Iyo giya bhokisi kana inodzikisira inoshandura iyo torque yekumhanya inobuda nemota kuita kumhanya uye torque inodiwa nemotokari yese.
Rudzi rwekutyaira mota
Iwo mota dzekutyaira dzakakamurwa kuita zvikamu zvina zvinotevera. Parizvino, AC induction motors uye magineti echigarire synchronous motors ndiwo akajairika marudzi emagetsi matsva emagetsi emagetsi. Saka isu tinotarisa pane tekinoroji yeAC induction mota uye yekusingaperi magineti synchronous mota.

1) AC Induction Asynchronous Motor
Iyo yekushanda musimboti we AC inductive asynchronous mota ndeyekuti mhepo inotenderedza ichapfuura nepakati pe stator slot uye rotor: yakarongedzerwa nematepi simbi mashiti ane yakakwirira magineti conductivity. Iwo matatu-chikamu magetsi achapfuura nepamhepo. Maererano nemutemo weFaraday's electromagnetic induction law, inotenderera magnetic field ichagadzirwa, ndicho chikonzero nei rotor ichitenderera. Iwo matatu makoiri e stator akabatanidzwa pane imwe nguva ye120 madhigirii, uye ikozvino-inotakura conductor inogadzira magineti akaipoteredza. Kana iyo matatu-phase magetsi emagetsi aiswa kune iyi yakakosha gadziriro, iyo magineti inochinja munzira dzakasiyana nekuchinja kwealternating current panguva yakatarwa, ichigadzira magnetic field ine uniform inotenderera intensity. Iyo inotenderera yekumhanya yemagnetic field inonzi synchronous speed. Ngatitii kondakita yakavharwa yakaiswa mukati, maererano nemutemo waFaraday, nokuti magnetic field inoshanduka, Iyo loop inonzwa simba re electromotive, iro richaita ikozvino muchiuno. Mamiriro ezvinhu aya akafanana neazvino anotakura loop mundima yemagineti, achigadzira simba remagetsi pachiuno, uye Huan Jiang anotanga kutenderera. Kushandisa chimwe chinhu chakafanana nekeji ye squirrel, nhatu-phase alternating current inobudisa magnetic field inotenderera kuburikidza ne stator, uye ikozvino ichave yakakonzerwa mu squirrel cage bar yakapfupiswa nemhete yekupedzisira, saka rotor inotanga kutenderera, iyo iri. nei mota ichinzi induction mota. Nerubatsiro rweelectromagnetic induction pane kuti yakabatana zvakananga kune rotor kupinza magetsi, insulating iron core flakes inozadzwa murotor, kuitira kuti diki saizi iron inovimbisa kushoma eddy ikozvino kurasikirwa.
2) AC synchronous mota
Iyo rotor ye synchronous mota yakasiyana neiyo asynchronous mota. Iyo magineti yechigarire inoiswa pane rotor, iyo inogona kukamurwa kuva pamusoro akaiswa mhando uye yakamisikidzwa mhando. Iyo rotor inogadzirwa nesilicon simbi sheet, uye magineti echigarire akaiswa mukati. Iyo stator inobatanidzwawo nealternating current ine phase musiyano we120, iyo inodzora ukuru uye chikamu che sine wave alternating current, kuitira kuti magnetic field inogadzirwa ne stator inopesana neiyo inogadzirwa ne rotor, uye magnetic field. munda uri kutenderera. Nenzira iyi, stator inokwezva nemagneti uye inotenderera ne rotor. Cycle mushure mekutenderera inogadzirwa ne stator uye rotor absorption.
Mhedziso: Iyo mota yemotokari yemotokari dzemagetsi yatove iyo huru, asi haina imwechete asi yakasiyana. Imwe neimwe mota drive system ine yayo yakazara index. Imwe neimwe sisitimu inoiswa mune iripo yemagetsi mota drive. Mazhinji acho maasynchronous motors uye anogara magineti synchronous motors, nepo vamwe vachiedza kushandura kusada mota. Zvakakodzera kutaura kuti mota dhiraivha inobatanidza tekinoroji yemagetsi emagetsi, tekinoroji yemagetsi, tekinoroji yedhijitari, otomatiki yekudzora tekinoroji, sainzi yemidziyo uye zvimwe zvirango kuratidza zvizere mashandisirwo uye tarisiro yekusimudzira yezvidzidzo zvakawanda. Mukwikwidzi akasimba mune mota dzemagetsi mota. Kuti utore nzvimbo mune ramangwana mota dzemagetsi, marudzi ese emotor haafanire kungokwidziridza chimiro chemota, asi zvakare kugara uchiongorora hungwaru uye dhijitari maficha ekutonga system.
