Iyo yakakosha yemagetsi mota yemagetsi kutonga ndeye mota control.Mubepa rino, musimboti wenyeredzi-delta kutanga unowanzoshandiswa muindasitiri unoshandiswa kukwenenzvera kudzora mota dzemagetsi, kuitira kuti 48V yemagetsi drive system inogona kuve iyo huru fomu ye10-72KW mota dhiraivha simba.Kuita kwemotokari yese kunovimbiswa, uye panguva imwe chete, mutengo wemagetsi emotokari madiki uye mini mota wakaderedzwa zvakanyanya,
Muchidzidzo chechangobva kuitika, ndakaona kuti kutonga kwemotokari dzemagetsi ndiko kutonga kwemotokari.Nekuti ruzivo rwakabatanidzwa muchinyorwa chino rwakakura uye rwakadzama, kana musimboti uye maitiro ekugadzirisa mota yekudzora chirongwa zvakatsanangurwa zvizere zvakadzama, maererano nemabhuku anoverengwa iye zvino nemunyori, ruzivo ruzivo rwakakwana kugadzira monograph. nemapeji anopfuura zana uye mazwi anopfuura 100,000.Kuti ubvumire vaverengi pa-self-media kuti vanzwisise uye vagone nzira yakadaro yekusimudzira mukati mezviuru zvemashoko.Ichi chinyorwa chichashandisa chaiyo mienzaniso kutsanangura maitiro ekugadzirisa iyo yemagetsi mota mota scheme.
Mienzaniso inotsanangurwa pano yakabva paBaojun E100, BAIC EC3, uye BYD E2.Chete maparamita anotevera emhando mbiri idzi anofanirwa kuve ane hukama, uye chete mota yekudzora inogadziriswa kuti ikwidze kuita 48V/144V DC dual-voltage bhatiri system, AC 33V/99V dual-voltage mota uye seti yemadhiraivha. .Pakati pavo, simba remagetsi emagetsi emutyairi wemotokari ndiyo kiyi yehurongwa hwese hwekugadzirisa, uye munyori ari kuidzidza zvakanyatsonaka uye zvakadzama.
Nemamwe manzwi, mota dzeBaojun E100, BAIC EC3, uye BYD E2 dzinongoda kuvandudzwa kusvika pa29-70KW motor control system.Ava ndivo vamiriri veA00 mini-mota, iyo A0 diki mota, uye iyo A compact pure yemagetsi mota.Ichi chinyorwa chichashandisa maindasitiri matatu-chikamu asynchronous mota yekudzora nzira yekuishandisa kune kutonga kwemagetsi mota mota kuburikidza nenyeredzi-delta, V/F + DTC matatu-chikamu asynchronous induction mota control.
Nekuda kwekugumira kwenzvimbo, chinyorwa ichi hachizotsananguri misimboti yenyota katatu uye zvichingodaro.Ngatitangei neakajairika mota simba muindasitiri mota control.Iyo inowanzo shandiswa 380V three-phase asynchronous motor is 0.18~315KW, simba diki iri Y connection, simba repakati iri △ connection, uye simba repamusoro i380/660V mota.Kazhinji, 660V mota ndiwo makuru mota pamusoro pe300KW.Hazvirevi kuti mota dziri pamusoro pe300KW hadzigone kushandisa 380V, asi kuti hupfumi hwavo hauna kunaka.Ndiyo ikozvino inodzikamisa hupfumi hwemotokari uye dunhu rekutonga.Kazhinji 1 square millimeter inogona kupfuura 6A ikozvino.Kana iyo matatu-phase asynchronous induction mota yagadzirwa, mota yayo inomonereka tambo inotemerwa.Ndiko kuti, kufamba kwazvino kunotarwa.Kubva pakuona kwemaindasitiri mota, 500A ndiyo yakakosha kukosha kwehupfumi hwayo.
Kudzokera kumota yemagetsi mota, iyo PWM matatu-chikamu voltage ye48V bhatiri system ndeye 33V.Kana iyo yehupfumi yemota yemaindasitiri iri 500A, iyo yakanyanya kukosha yehupfumi ye48V mota yemagetsi ingangoita 27KW kune matatu-chikamu induction mota.Panguva imwecheteyo, tichifunga nezvemaitiro emagetsi emotokari, nguva yekusvika pakakwirira ikozvino ipfupi kwazvo, kazhinji isingasviki maminetsi mashoma, kureva kuti, 27KW inogona kuitwa mune yakawandisa mamiriro.Kazhinji iyo yekuremedza mamiriro ndeye 2 kusvika 3 nguva dzeyakajairika mamiriro.Kureva kuti, yakajairika kushanda mamiriro 9 ~ 13.5KW.
Kana isu tikangotarisa padanho revoltage uye ikozvino kugona kuenderana.Iyo 48V system inogona chete kuva mukati me30KW sezvo kutyaira kwakanaka kuri iko kwakanyanya kushanda mamiriro.
Nekudaro, kune dzakawanda nzira dzekudzora dzematatu-chikamu asynchronous mota.Motokari dzemagetsi dzine huwandu hwakasiyana-siyana hwekumhanya (inenge 0-100%) uye torque control range (inenge 0-100%).Pasi pemamiriro ekushanda akaomarara, mota dzemagetsi parizvino dzinonyanya kushandisa VF kana DTC control.Kana nyeredzi-delta control ikaunzwa, inogona kukonzera mhedzisiro isingatarisirwe.
Mukutonga kwemaindasitiri, iyo nyeredzi-delta control voltage ndeye 1.732 nguva, inova masangana kwete musimboti.Iyo 48V sisitimu haikwidzire PWM frequency modulation kuita AC 33V, uye mota yakagadzirwa zvinoenderana neindasitiri mota voltage level i57V.Asi isu tinogadzirisa nyeredzi-delta control voltage level kusvika katatu, inova mudzi we9.Ipapo yaizova 99V.
Kureva kuti, kana mota yakagadzirwa se99V AC matatu-chikamu asynchronous mota ine delta yekubatanidza uye 33V Y yekubatanidza, iyo mota yekumhanya inogona kugadziridzwa kubva pa0 kusvika 100% mukati mesimba renji re20 kusvika 72KW pasi pehupfumi. mamiriro.Kazhinji kumhanya kwakanyanya kwemota i12000RPM), torque regulation iri 0-100%, uye frequency modulation ndeye 0-400Hz.
Kana chirongwa chakadaro chekugadzirisa chichigona kuitika, saka mota dzeA-kirasi uye mota diki dzinogona kuwana kuita kwakanaka kuburikidza nemota imwe.Isu tinoziva kuti mutengo we48V mota system (mukati meiyo yepamusoro kukosha kwe30KW) ingangoita zviuru zvishanu zveyuan.Mutengo weiyo optimization chirongwa mune ino pepa hauzivikanwe, asi haiwedzeri zvinhu, asi inongoshandura nzira yekudzora uye inounza maviri maviri voltage mazinga.Kuwedzera kwayo mutengo kunodzoreka zvakare.
Zvechokwadi, pachava nezvinetso zvitsva zvakawanda muchirongwa chekutonga chakadaro.Matambudziko makuru dhizaini yemota, dhizaini yemutyairi, uye zvakanyanya zvinodikanwa zvekuchaja uye kuburitsa hunhu hweiyo yakakwira-voltage bhatiri pack.Matambudziko aya anodzoreka uye kune magadzirirwo aripo.Semuenzaniso, mota dhizaini inogona kugadziriswa nekugadzirisa chiyero chepamusoro uye yakaderera voltage voltage mazinga.Tichazvikurukura pamwe chete munyaya inotevera.
