46. ​​Ni irihe tandukaniro riri hagati ya moteri ya 180W na 250W?Nibihe bisabwa kubagenzuzi?Imiyoboro ya 250W igenda nini, isaba imbaraga zingana kandi zizewe mugenzuzi.

47. Kuki mubidukikije bisanzwe, kugendesha ibinyabiziga byamashanyarazi bizaba bitandukanye bitewe na moteri zitandukanye za moteri?Nkuko twese tubizi, mubihe bisanzwe, ubaze hamwe nu mutwaro wagereranijwe wa 160W, umuyoboro ugenda kuri moteri ya 250W DC ni 4-5A, naho umuvuduko wo kugenda kuri moteri ya 350W DC uri hejuru gato.

Kurugero: niba ingufu za bateri ari 48V, moteri ebyiri ni 250W na 350W, naho amanota yabyo yagereranijwe ni 80%, noneho amashanyarazi yagenwe ya moteri ya 250W agera kuri 6.5A, mugihe amashanyarazi yagenwe ya moteri ya 350W ni nka 9A.

Imikorere ya moteri rusange ni uko uko ibikorwa bigenda bitandukana nu mikorere yagenwe, agaciro ni gake.Kubijyanye numutwaro wa 4-5A, imikorere ya moteri 250W ni 70%, naho moteri ya 350W ni 60%.5Umutwaro,

Imbaraga zisohoka za 250W ni 48V * 5A * 70% = 168W

Imbaraga zisohoka za 350W ni 48V * 5A * 60% = 144W

Ariko, kugirango imbaraga zisohoka za moteri ya 350W zujuje ibyangombwa byo gutwara, ni ukuvuga kugera kuri 168W (hafi umutwaro wagenwe), inzira yonyine yo kongera amashanyarazi ni ukongera ingingo ikora neza.

48. Kuki urugendo rwibinyabiziga byamashanyarazi bifite moteri ya 350W bigufi kuruta ibya moteri 250W munsi yibidukikije?Bitewe nibidukikije bimwe, moteri yamashanyarazi ya 350W ifite moteri nini yo kugenda, bityo mileage izaba mugufi mugihe kimwe cya bateri.

49. Nigute abakora amagare yamashanyarazi bagomba guhitamo moteri?Ukurikije icyo guhitamo moteri?Ku binyabiziga byamashanyarazi, ikintu cyingenzi muguhitamo moteri yacyo ni uguhitamo imbaraga zapimwe za moteri.

Guhitamo imbaraga zapimwe za moteri muri rusange bigabanyijemo intambwe eshatu:intambwe yambere nukubara imbaraga zumutwaro P;intambwe ya kabiri ni uguhitamo mbere imbaraga zapimwe za moteri nabandi ukurikije imbaraga zumutwaro.Intambwe ya gatatu ni ukugenzura moteri yatoranijwe mbere.

Mubisanzwe, genzura ubushyuhe nubushyuhe bwambere, hanyuma urebe ubushobozi burenze, hanyuma urebe ubushobozi bwo gutangira nibiba ngombwa.Niba byose byanyuze, moteri yabanjirije yatoranijwe;niba bitanyuze, tangira kuva ku ntambwe ya kabiri kugeza unyuze.Ntukuzuze ibisabwa mumitwaro, ntoya imbaraga zapimwe za moteri, nubukungu nubukungu.

Nyuma yintambwe ya kabiri irangiye, gukosora ubushyuhe bigomba gukorwa ukurikije itandukaniro ryubushyuhe bwibidukikije.Imbaraga zapimwe zikorwa hashingiwe ko ubushyuhe bwibidukikije bwigihugu ari dogere selisiyusi 40.Niba ubushyuhe bwibidukikije buri hasi cyangwa hejuru yumwaka wose, imbaraga zapimwe za moteri zigomba gukosorwa ukoresheje neza ubushobozi bwa moteri mugihe kizaza.Kurugero, niba ubushyuhe bwimyaka buri hasi, imbaraga zapimwe za moteri zigomba kuba hejuru kurenza Pn isanzwe.Ibinyuranye, niba ubushyuhe bwimyaka buri hejuru, imbaraga zapimwe zigomba kugabanuka.

Muri rusange, iyo hagaragaye ubushyuhe bwibidukikije, moteri yikinyabiziga cyamashanyarazi igomba gutoranywa ukurikije uko ikinyabiziga kigenda.Imiterere yimodoka yamashanyarazi irashobora gutuma moteri yegera leta ikora neza, nziza.Imiterere yumuhanda muri rusange igenwa ukurikije uko umuhanda umeze.Kurugero, niba umuhanda uri muri Tianjin uringaniye, moteri ifite ingufu nkeya irahagije;niba moteri ikoresha ingufu nyinshi, ingufu zizaba impfabusa kandi mileage izaba mugufi.Niba hari umuhanda munini wimisozi muri Chongqing, birakwiye gukoresha moteri ifite imbaraga nini.

Moteri ya dogere 50.60 DC idafite imbaraga zirenze moteri ya DC ya dogere 120, sibyo?Kubera iki?Kuva ku isoko, usanga kwibeshya nkibi bikunze kuvugana nabakiriya benshi!Tekereza moteri ya dogere 60 irakomeye kurenza dogere 120.Duhereye ku ihame rya moteri idafite amashanyarazi nukuri, ntacyo bitwaye niba ari moteri ya dogere 60 cyangwa moteri ya dogere 120!Icyitwa impamyabumenyi zikoreshwa gusa kubwira umugenzuzi wa brushless igihe cyo gukora insinga ebyiri zicyiciro cyo kwita.Ntakintu nakimwe gikomeye kurusha abandi!Kimwe nukuri kuri dogere 240 na dogere 300, ntamuntu urusha undi.
