Yeyiphi ibhayisekile yombane eyiyeyona ilungileyo? Iigiya iimoto? phakathi kwedrive motor? Imoto engaphambili?
Imoto ye-e-bike idityanisiwe kwisakhelo kwaye ayinakutshintshwa ngokulula njengezinye izinto, yiyo yonke into ekufuneka uyazi ngaphambi kokuba uthenge ibhayisekile yakho elandelayo
Ezona motor ze-e-bike ezilungileyo ziya kulinganisa izikali phakathi kwamandla nobunzima, ukubonelela ngoncedo oluphezulu ngaphandle kokulinganisa ibhayisekile kwaye uyibambe umva. Ewe, i-e-bike motors iza njengenxalenye yebhayisekile ngokwayo kwaye ayikabiyonxalenye onokuyitshintsha kwaye uyihlaziye, Eyona bhayisekile yombane ihamba phambili ke kubalulekile ukuba wazi ukuba ungena phi xa ukhetha ezona bhayisikile zombane.
I-e-bhayisekile izinzile kwaye izinzile ngokwayo njengenxalenye exabisekileyo kwikamva lokuhamba ngebhayisikile. Apho intengiso yayilawulwa ziibhayisikile zombane zokuhamba, ngoku ityebile ngeebhayisikile ezihamba phambili zombane kunye neebhayisikile ezilungileyo kakhulu zegrabile zombane.
Kuzo zonke izibonelelo zeebhayisikile ze-e, zinokudala ukudideka kunye noxinzelelo lobunini, ezibangelwa yiteknoloji ethe kratya egobayo yokunika amandla ezi bhayisekile. Njengazo zonke izinto zombane, ingcinga kukuba ukuthengwa kokulibaziseka kungcono, kukuvumela ukuba uxhamle ekuthatheni iteknoloji yamva nje.
Kodwa ukuba awunalo nofifi lokuba ungaqala ngaphi, silapha ukuze sincede ekupheliseni isiphithiphithi esijikeleze ezona moto zihamba ngeebhayisikile, kunye nezinto abanokukwazi ukuzenza.
Ibhayisikile yokuzingela yombane inokuxhotyiswa ngazo naziphi na ezi ndidi zintathu zeemoto, nganye ihambisa ukusebenza okungafaniyo kwiindawo ezahlukeneyo. Imoto yehabhu yangasemva (ibekwe kwivili elingasemva) ivelisa amandla amakhulu ekrwada kwaye lukhetho olusebenzayo njengoko ludinga ukugcinwa okuncinci kwaye ihlala ixabisa ngexabiso eliphantsi. Nangona kunjalo, i-torque yayo ephantsi iyenza buthathaka xa inyuka umzila.
Imoto esembindini yokuqhuba (ibekwe phakathi kweepali zebhayisikile) ine-torque eyomeleleyo xa kuthelekiswa nemoto yehabhu yangasemva. Ke, inokunyuka ngcono kwaye ngokulula. Kwicala elisezantsi, iibhayisekile ezinolu hlobo lweemoto zinokubiza kakhulu kwaye zifuna ulondolozo ngakumbi.
Okokugqibela, i-motor mid drive drive ibonelela ngolawulo olululo kunye nokusebenza phakathi kwezi ntlobo zintathu. Njengenguqulo ephuculweyo yemoto esembindini, inamandla ngakumbi kwaye isebenza ngokufanelekileyo ngakumbi xa ucanda ukunyuka. Kodwa njengoko kulindelwe, iza nexabiso elikhulu nangona ifuna ulondolozo oluncinci.
Inkqubo yeelebhali yangaphakathi ye-Bafang ibiza le MM G510.1000, kwaye uyilo lwenza uphuculo oluninzi ngaphezulu kwedrive yam endiyithandayo, i-BBSHD. I-BBSHD yikhithi eslayidayo malunga nayo nayiphi na ifreyimu oyithandayo, kodwa i-Ultra Max ifuna iqokobhe lobunini ukuyinyusa (jonga ngezantsi).
Into yokuqala ephumayo kumntu obukele ngokungaqhelekanga kukuba i-Ultra inemoto enobubanzi obukhulu. Oku kwonyusa inani lokuphakanyiswa kwemagnethi ekujikelezeni irotor, ngaphandle kweewatt ezongezelelweyo ezisetyenzisiweyo kuyo, xa kuthelekiswa neewatts ezifanayo ezisetyenziswa kwimoto encinci enobunzima obunobhedu obufanayo. Enye into encedisayo kukusebenza ngokukuko, kuba "isantya semagnethi eshukumayo" sikhawuleza kwi-RPM.
Oko kuthetha ukuba… umlawuli uzakufaka ii-amps eziphezulu kwii-electromagnets kwi-stator de iimagnethi ezisisigxina kwi-rotor zijikeleze ngokwaneleyo ukufikelela kwisantya esiphezulu se-motors, ebizwa ngokuba yi "Kv" yentsimbi (cofa apha ye "motor tech, funda imigaqo").
Ngokukhawuleza iimagnethi zidlulana, zishiyana ukufinyela kweewatts… ezithi zisetyenziswe koomazibuthe. Usebenziso oluninzi lwee-pulses ezincinci 'zinokubonelela ngamandla afanayo asetyenzisiweyo, xa kuthelekiswa nokusebenzisa iipulse ezinde ezimbalwa, kodwa… ukusebenzisa iipulse ezinde "kwi" kuya kutshisa i-MOSFET's kulawulo, kunye ne-electromagnets kwi-stator.
Qaphela ukuba i-Ultra Max stator incinci kune-BBSHD, kodwa ubukhulu bukhulu ngokwaneleyo ukuba bunobhedu obuninzi.
Enye into ekufuneka uyiqaphele kukuba i-BBS02 kumfanekiso ongentla isebenzisa oko kubizwa ngokuba yi "Surface Permanent Magnets" / SPM kwi-Rotor, kwaye i-Ultra (kunye ne-BBSHD) isebenzisa isitayile esifaka iimagnethi kumgama omncinci kude Umphezulu weRoror. Olu hlobo lubonwa rhoqo kwezi ntsuku, kwaye lubizwa ngokuba yi “Interior Permanent Magnet” motor / IPM.
Olu luyilo luvumela iimagnethi ukuba ziqhubeke zipholile, nto leyo ibalulekile kuba enye yezithintelo kwindlela ii-amps ezinokusebenziseka ngayo yimoto bubushushu obuveliswa "yimisinga eddy". Isiseko se-stator senziwe kwisitaki seepleyiti zentsimbi ezibhityileyo kakhulu ukunciphisa imisinga eddy, eveliswayo nangaliphi na ixesha isinyithi esineentsimbi sidlula ngokukhawuleza kumazibuthe.
Sebenzisa i-stator-core eyenziwe ngamacwecwe amade aluhlaza (agalelwe i-lacquer ngombane ukwahlula ipleyiti enye kwenye) yindlela ebiza iindleko yokufezekisa umda wobushushu obukhoyo ngoku, kodwa… ngokungafaniyo ne-stator-core Iimagnethi zizinto eziqinileyo zesinyithi. Ngoyilo lweemoto ezindala ze-SPM, umzimba womazibuthe ngokwawo uba sisiseko sobushushu benkunkuma.
Nge-IPM, iimagnethi ezisisigxina ziya "kwenza umazibuthe" icandelo elincinci lesinyithi phakathi kwabo kunye nee-electromagnets kwi-stator. Oku kugcina amandla omazibuthe kwisithuba somoya kwinqanaba elamkelekileyo, ngelixa ubeka oomazibuthe abasisigxina umgama omfutshane kude nesikhewu somoya. Iimagnethi ezisisigxina zinokuphulukana namandla azo ombane ukuba zishushu kakhulu, ke… ngokwenza oku, ungasebenzisa ii-amps ezininzi "zethutyana lokuphakama" ngaphandle kokutshisa iimagnethi.
