A "2023 Dongfeng Motor Brand Conference Conference" a ranar 10 ga Afrilu, an fitar da sabon alamar wutar lantarki ta Mach E. E yana nufin lantarki, babban inganci, ceton makamashi da kare muhalli.Mach E ya ƙunshi manyan dandamalin samfura guda uku: lantarki, baturi da ƙarin makamashi.

 

Daga cikin su, sashin motar lantarki na Mach yana da halaye masu zuwa:

 

  • Motoci tare da fasahar rotor mai rufi na fiber fiber, saurin zai iya kaiwa 30,000 rpm;
  • mai sanyaya;
  • Flat waya stator tare da 1 Ramin da 8 wayoyi;
  • Mai sarrafa SiC mai haɓaka kansa;
  • Matsakaicin ingantaccen tsarin zai iya kaiwa 94.5%.

 

Idan aka kwatanta da sauran fasahohin,rotor mai rufaffen fiber carbon da matsakaicin gudun rpm 30,000 sun zama fitattun fitattun abubuwan wannan tuƙi na lantarki.

Matsakaicin saurin sabon injin makamashin ya ƙaru daga farkon 10,000rpm zuwa yanzu sanannen 15,000-18,000rpm.Kwanan nan, kamfanoni sun ƙaddamar da tsarin sarrafa wutar lantarki fiye da 20,000rpm, don haka me yasa saurin sabbin injinan makamashi ke karuwa kuma mafi girma?

 

Ee, sakamakon farashi!

 

Abubuwan da ke biyowa shine nazarin alaƙar da ke tsakanin saurin motar da farashin motar a matakan ka'ida da simulation.

 

Sabon tsarin tuƙi mai tsaftar wutar lantarki gabaɗaya ya haɗa da sassa uku, injin, mai sarrafa motar da akwatin gear.Mai sarrafa motar shine ƙarshen shigar da makamashin lantarki, akwatin gear shine ƙarshen fitarwa na makamashin inji, kuma motar ita ce juzu'in juzu'in wutar lantarki da makamashin injina.Hanyar aiki ita ce mai sarrafawa yana shigar da makamashin lantarki (na yanzu * ƙarfin lantarki) cikin motar.Ta hanyar hulɗar makamashin lantarki da ƙarfin maganadisu a cikin motar, yana fitar da makamashin inji (gudun * karfin juyi) zuwa akwatin gear.Akwatin gear yana tafiyar da abin hawa ta hanyar daidaita saurin gudu da fitarwa ta motar ta hanyar rage raguwar kaya.

 

Ta hanyar nazarin dabarar jujjuyawar motsi, ana iya ganin cewa ƙarfin fitarwar motar T2 yana da alaƙa da haɓakar motar.

N shine adadin juzu'i na stator, Ni ne shigar da halin yanzu na stator, B shine yawan juzu'in iska, R shine radius na core na rotor, L shine tsayin ainihin motar.

 

A cikin yanayin tabbatar da adadin jujjuyawar motar, shigar da halin yanzu na mai sarrafawa, da kuma jujjuyawar tazarar iska, idan buƙatun fitowar T2 na injin ɗin ya ragu, tsayi ko diamita na injin. Ƙarfe core za a iya rage.

 

Canje-canjen tsayin ɗigon motar ba ya haɗa da canji na stamping mutu na stator da rotor, kuma canjin yana da sauƙin sauƙi, don haka aikin da aka saba shine don ƙayyade diamita na ainihin kuma rage tsayin ainihin. .

 

Yayin da tsayin ƙarfe na ƙarfe ya ragu, adadin kayan lantarki (baƙin ƙarfe, ƙarfe na ƙarfe, iska mai motsi) na motar yana raguwa.Kayayyakin lantarki suna ƙididdige kaso mai yawa na farashin motar, wanda ya kai kusan 72%.Idan za a iya rage karfin wutar lantarki, za a rage farashin motar sosai.

Saboda sababbin motocin makamashi suna da ƙayyadaddun buƙatun ƙarshen dabaran, idan za a rage ƙarfin fitarwa na motar, dole ne a ƙara yawan gudun mashin ɗin don tabbatar da ƙarfin ƙarshen abin hawa.

T1=T2×r

n1 shine saurin ƙarshen dabaran, n2 shine saurin injin, T1 shine ƙarfin ƙarshen dabaran, T2 shine jujjuyawar injin, kuma r shine raguwar raguwa.

 

Kuma saboda sabbin motocin makamashi har yanzu suna da abin da ake buƙata na matsakaicin gudu, matsakaicin saurin abin hawa kuma zai ragu bayan an ƙara saurin saurin akwatin gear, wanda ba za a yarda da shi ba, don haka yana buƙatar cewa dole ne a ƙara saurin motar.

 

A takaice,bayan motar ta rage karfin juyi da sauri, tare da ma'auni mai ma'ana, zai iya rage farashin motar yayin da yake tabbatar da buƙatar wutar lantarki na abin hawa.

Tasirin saurin de-torsion akan wasu kaddarorin01Bayan rage karfin juyi da sauri, tsayin motar motar ya ragu, zai shafi ikon? Bari mu dubi tsarin wutar lantarki.

U shine wutar lantarki na zamani, Ni ne shigar da halin yanzu na stator, cos∅ shine ƙarfin wutar lantarki, kuma η shine inganci.

 

Ana iya gani daga ma'auni cewa babu wasu sigogi da suka danganci girman motar a cikin dabarar ikon fitarwa na motar, don haka canjin tsayin motar motar yana da ɗan tasiri akan ƙarfin.

 

Mai zuwa shine sakamakon siminti na halayen waje na wani injin. Idan aka kwatanta da yanayin yanayin waje na waje, tsayin ƙarfe na ƙarfe ya ragu, ƙarfin fitarwa na motar ya zama karami, amma matsakaicin ƙarfin fitarwa ba ya canzawa da yawa, wanda kuma ya tabbatar da ƙaddamar da ka'idar da ke sama.
