Ubuchwephesha obunamava ashushu 36V 48V Hub Motors ngeFactory Wholesale Price

Nayiphi na imveliso yombane, kubandakanywa iimveliso zemoto, ngokuqinisekileyo, ichaze amandla ombane ayo alinganisiweyo ukuze asebenze ngokwesiqhelo, kwaye nakuphi na ukutenxa kwamandla ombane kuya kubangela iziphumo ezibi ekusebenzeni okuqhelekileyo kwezixhobo zombane.
Kwizixhobo ezikumgangatho ophezulu, izixhobo zokukhusela eziyimfuneko zamkelwe.Xa i-voltage yonikezelo lwamandla ingaqhelekanga, ukunikezelwa kombane kunqunyulwa ukukhusela.Kwizixhobo ezichanekileyo, umbane ongapheliyo-voltage usetyenziselwa ukulungiswa.Nangona kunjalo, ukuba nokwenzeka kweemveliso zeemoto, ngakumbi iimveliso zeemoto zemizi-mveliso, ukusebenzisa izixhobo ze-voltage rhoqo zincinci kakhulu, kwaye kukho iimeko ezininzi zokukhusela umbane.
Kwiimotor zesigaba esisodwa, kukho iimeko ezimbini kuphela: i-voltage ephezulu kunye ne-voltage ephantsi, ngelixa i-motor-phase modules, kukho ingxaki yokulinganisela kwamandla.Impembelelo ethe ngqo kwezi zintathu zokutshintshwa kwamandla ombane kukunyuka kwangoku okanye ukungalingani kwangoku.
Ngokweemeko zobugcisa zemoto, ukutenxa kokuguquguquka kombane olinganisiweyo wemoto ayinakudlula i-10%, kwaye i-torque yemoto ihambelana ngokuthe ngqo kwisikwere se-terminal voltage yemoto.Xa i-voltage iphezulu kakhulu, i-motor core iya kuba kwimo ye-saturation yamagnetic, kwaye ukonyuka kwe-stator yangoku kuya kukhokelela ekufudumeni okunzulu kwe-winding, kunye nengxaki yomgangatho wokutshisa ukuvutha.Nangona kunjalo, kwimeko yombane ophantsi, kunokubakho iingxaki ekuqaleni kwemoto, ngakumbi kwimoto ebalekayo.Ukuze kuhlangatyezwane neemfuno zemoto esebenza kumthwalo, umsinga kufuneka ukwandiswe, kwaye isiphumo sokunyuka kwangoku kuya kuba kukufudumeza okanye ukutshisa i-winding, ngakumbi ekusebenzeni kwexesha elide le-voltage ephantsi, nto leyo enzulu ngakumbi.
I-voltage engalinganiyo yenqanaba lesithathu lemoto yingxaki yobonelelo lwamandla.Xa i-voltage ingalingani, ngokuqinisekileyo iya kukhokelela kwi-motor engalinganiyo yangoku.Icandelo elibi lokulandelelana kwe-voltage engalungelelananga livelisa intsimi yamagnetic kwisithuba somoya wemoto echasene nokujikeleza kwe-rotor.Inxalenye encinci yolandelelwano olubi lombane lunokwenza ukuba umbane oqukuqelayo ube mkhulu kunomjelo xa umbane ulinganisiwe.I-frequency yangoku equkuqelayo kwi-rotor bar iphantse iphindwe kabini i-frequency rated, ngoko umphumo wangoku wokucudisa kwi-rotor bar yenza ilahleko eyongeziweyo yexabiso le-rotor ejikelezayo enkulu kakhulu kune-stator winding.Ukunyuka kweqondo lokushisa kwe-stator winding kuphezulu kune-stator ehamba phantsi kwe-voltage elinganayo.
Xa i-voltage ingalingani, i-torque ye-rotor evaliweyo, i-torque encinci kunye ne-torque ephezulu yemoto iya kuncipha.Ukuba ukungalingani kwe-voltage kunzulu, i-motor ayiyi kusebenza ngokuqhelekileyo.
Xa i-motor isebenza ngomthwalo opheleleyo phantsi kwe-voltage engalinganiyo, ngenxa yokuba isantya se-slip sanda ngokunyuka kokulahleka okongeziweyo kwe-rotor, isantya siya kuncipha kancinci ngeli xesha.Ngokunyuka kwe-voltage (okwangoku) ukungalingani, ingxolo kunye nokunyakaza kwemoto kunokunyuka.Ukungcangcazela kungonakalisa imotor okanye inkqubo yonke yokuqhuba.
Ukuze kuchongwe ngokukuko oonobangela bokungalingani kwamandla ombane weemoto, oku kunokwenziwa ngokubhaqwa kombane wobonelelo lwamandla okanye utshintsho lwangoku.Uninzi lwezixhobo zixhotyiswe ngezixhobo zokubeka iliso kwi-voltage, ezinokuhlahlelwa ngokuthelekisa idatha.Kulabo abangenazo izixhobo zokubeka iliso, ukufunyanwa rhoqo okanye ukulinganisa kwangoku kufuneka kwamkelwe.Kwiimoto ezinokujikeleza phambili nangasemva, ungatshintsha ngokungenasizathu imigca yonikezelo lwamandla ezigaba ezibini kwaye ujonge utshintsho lwangoku, ngelixa uhlalutya ngokungathanga ngqo ibhalansi yombane.Emva kokuphelisa ingxaki yombane ongalinganiyo, kunokubandakanya iingxaki ezisemgangathweni ezifana nokujika kunye nesigaba ukuya kwisigaba.
