njinga yamoto
Kodi njinga yamagetsi ndiyiti yabwino kwambiri? magiya mota? mid drive mota? kutsogolo galimoto?
E-njinga yamagalimoto ndiyophatikizika ndi chimango ndipo sichingasinthidwe mosavuta monga zinthu zina, ndiye Nazi zonse zomwe muyenera kudziwa musanagule njinga yamagetsi yotsatira
Ma motor e-bicycle abwino kwambiri azitha kuyeza sikelo pakati pa mphamvu ndi kulemera, kuti apereke chithandizo chazitali kwambiri osalemetsa njingayo ndikuyibweza. Zachidziwikire, ma motokala a e-njinga amabwera ngati gawo la njinga yokha ndipo sanakhalebe gawo limodzi lomwe mutha kusinthana ndikusintha, Njinga zamagetsi zabwino kwambiri zapakatikati chifukwa chake ndikofunikira kudziwa zomwe mukulowa posankha njinga zamagetsi zabwino kwambiri.
E-njinga yakhazikika bwino ndipo imadzikhazikitsa ngati gawo lofunika m'tsogolo mwa njinga. Kumene msika unali wolamulidwa ndi njinga zamagetsi zoyendera, tsopano uli ndi njinga zamagetsi zamagetsi zabwino kwambiri komanso njinga zamagetsi zabwino kwambiri.
Pazabwino zonse zama e-bikes, amathanso kubweretsa chisokonezo komanso nkhawa za umwini, zomwe zimayambitsidwa ndi njira yokhotakhota yolimbitsa njinga izi. Monga zinthu zonse zamagetsi, lingaliro ndikuti kugula kochedwetsa ndibwino, kukulolani kuti mupindule pakujambula ukadaulo waposachedwa.
Koma ngati simukudziwa komwe mungayambire, ndiye kuti tili pano kuti tithandizire kuthetsa chisokonezo chokhudza ma motokala abwino kwambiri a e-bike, ndi zomwe angathe.
Njinga yamagetsi yosaka yamagetsi imatha kukhala ndi mitundu itatu yamtundu uliwonse yamagalimoto, iliyonse imapereka magwiridwe antchito osiyanasiyana m'malo osiyanasiyana. Magalimoto oyenda kumbuyo (omwe amayikidwa kumbuyo kwa gudumu lakumbuyo) amatulutsa mphamvu yayikulu yaiwisi ndipo ndichisankho choyenera chifukwa amafunikira kukonza kocheperako ndipo nthawi zambiri amakhala pamtengo wotsika mtengo. Komabe, kutsika kwake kumapangitsa kukhala kofooka mukamakwera njanji.
Njinga yamagalimoto yapakatikati (yomwe ili pakati pa zoyendetsa njinga zamoto) imakhala ndi makokedwe olimba poyerekeza ndi mota wakumbuyo wakumbuyo. Chifukwa chake imatha kukwera bwino komanso mosavuta. Pazovuta, njinga zamoto zamtunduwu zitha kukhala zotsika mtengo ndipo zimafunikira kukonza zambiri.
Pomaliza, mota wama Ultra mid drive umawongolera ndikuchita bwino pakati pa mitundu itatu. Momwe mtundu wamagalimoto wapakatikati umasinthidwa, umakhala wamphamvu kwambiri komanso wothandiza makamaka mukamadutsa phiri. Koma monga zikuyembekezeredwa, zimadza ndi mtengo wokwera ngakhale zimafunikira kukonza pang'ono.
Dongosolo lolembera mkati la Bafangs limatcha iyi MM G510.1000, ndipo kapangidwe kake kamasintha zina zingapo pagalimoto yomwe ndimakonda, BBSHD. BBSHD ndi chida chomwe chimangoyenda pafupifupi chimango chilichonse chomwe mumakonda, koma Ultra Max imafuna chipolopolo kuti chikwere (onani pansipa).
Chinthu choyamba chomwe chimatuluka mwa owonera wamba ndikuti Ultra ili ndi mota yayikulu yayikulu. Izi zimapangitsa kuchuluka kwamagetsi komwe maginito amagwiritsa ntchito potembenuka mozungulira, popanda ma watt ena owonjezera omwe amagwiritsidwa ntchito, poyerekeza ndi ma watt omwewo omwe amagwiritsidwa ntchito pamakina ang'onoang'ono okhala ndi mkuwa womwewo. China chomwe izi zimathandizira ndichabwino, popeza "kuthamanga kwamagetsi kwamagetsi" ndikofulumira kwa RPM yomwe yapatsidwa.
Zomwe zikutanthawuza ndikuti ... wowongolera adzagwiritsa ntchito ma ampu apamwamba pamagetsi amagetsi mu stator mpaka maginito okhazikika mu rotor akuyenda mwachangu mokwanira kuti afikire liwiro lamphamvu la motors, lotchedwa "Kv" la kumulowetsa (dinani apa za "motor tech, phunzirani mawu").
Kuthamanga kwa maginito kumadutsirana, ndikufupikitsa ma watts ali… omwe amagwiritsidwa ntchito pamagetsi yamagetsi. Kugwiritsa ntchito tinthu tating'onoting'ono tambiri 'kumatha' kupereka mphamvu zonse zomwe zimagwiritsidwa ntchito, poyerekeza kugwiritsa ntchito nyemba zazing'ono zochepa, koma… kugwiritsa ntchito nyemba zazitali "kutulutsa" kutenthe MOSFET mu woyang'anira, komanso ma elektromagneti mu stator.
Dziwani kuti Ultra Max stator ndi yocheperako kuposa BBSHD, koma m'mimba mwake ndi yayikulu mokwanira kuti imakhala ndi mkuwa wochulukirapo.
China chomwe tiyenera kudziwa ndichakuti BBS02 yomwe ili pachithunzipa pamwambapa imagwiritsa ntchito zomwe zimatchedwa "Surface Permanent Magnets" / SPM pa rotor, ndipo Ultra (pamodzi ndi BBSHD) imagwiritsa ntchito kalembedwe komwe amaika maginito patali pang'ono ndi Pamwamba pa ozungulira. Mtunduwu ukuwoneka kwambiri masiku ano, ndipo umatchedwa "Interior Permanent Magnet" mota / IPM.
Kupanga kumeneku kumapangitsa maginito kuti azizizira kwambiri, zomwe ndizofunikira chifukwa chimodzi mwazomwe zingagwiritse ntchito ma amps oyendetsa galimoto ndi kutentha komwe kumapangidwa ndi "ma eddy current". Phata la stator limapangidwa kuchokera pakatundu kakang'ono kwambiri kazitsulo kuti muchepetse mafunde akuthwa, omwe amapangidwa nthawi iliyonse chitsulo chachitsulo chikadutsa mwachangu maginito.
Kugwiritsa ntchito stator-core yomwe imapangidwa ndi mbale zopapatizidwa (zokutidwa ndi lacquer kuti ipatuleko mbale imodzi ndi inzake) ndi njira yotsika mtengo yokwaniritsira kutentha kwaposachedwa, koma ... mosiyana ndi laminated stator-core , maginito ndizitsulo zolimba zazitsulo. Ndi kapangidwe ka mota wakale wa SPM, thupi la maginito limakhala gwero la kutentha kwanyengo.
Ndi IPM, maginito okhazikika "azigwiritsa ntchito maginito" gawo laling'ono lazitsulo pakati pawo ndi ma elekitiroma mu stator. Izi zimapangitsa kuti mphamvu yamaginito ikhale yolumikizana ndi mpweya pamlingo wovomerezeka, pomwe ikayika maginito okhazikika patali pang'ono ndi mpweya. Maginito okhazikika atha kutaya mphamvu zamaginito ngati atentha kwambiri, chifukwa chake ... pochita izi, mutha kugwiritsa ntchito ma "amp" apamwamba osapitilira maginito.
