Ubuchwepheshe abanolwazi olushisayo 36V 48V Hub Motors ngeFactory Wholesale Price

Noma yimuphi umkhiqizo kagesi, okuhlanganisa nemikhiqizo yemoto, vele, ucacisile amandla kagesi awo alinganiselwe ukuze asebenze ngokujwayelekile, futhi noma yikuphi ukuchezuka kwamandla kagesi kuzodala imiphumela emibi ekusebenzeni okuvamile kwezinto zikagesi.
Okokusebenza okusezingeni eliphezulu, kwamukelwa amathuluzi okuvikela adingekayo.Uma amandla kagesi engajwayelekile, ugesi uyanqanyulwa ukuze uvikeleke.Kumathuluzi anembe kakhulu, ukunikezwa kwamandla kagesi okungaguquki kusetshenziselwa ukulungiswa.Kodwa-ke, amathuba emikhiqizo yezimoto, ikakhulukazi imikhiqizo yezimoto zezimboni, ukusebenzisa amadivaysi anamandla kagesi mancane kakhulu, futhi kunezimo eziningi zokuvikela ukucisha ugesi.
Kuma-motor esigaba esisodwa, kunezimo ezimbili kuphela: i-voltage ephezulu ne-voltage ephansi, kanti kumamotho ezigaba ezintathu, kunenkinga yokulinganisa kwamandla kagesi.Umthelela oqondile walokhu kuchezuka kwama-voltage amathathu ukwanda kwamanje noma ukungalingani kwamanje.
Ngokwezimo zobuchwepheshe zemoto, ukuchezuka kokuguquguquka kwe-voltage elinganiselwe yemoto akukwazi ukudlula u-10%, futhi i-torque yemoto ilingana ngokuqondile nesikwele se-voltage yokugcina yemoto.Uma i-voltage iphezulu kakhulu, i-motor core izoba sesimweni sokugcwala kazibuthe, futhi ukwanda kwe-stator current kuzoholela ekushiseni okungathi sína kokusonga, ngisho nenkinga yekhwalithi yokushiswa kwamawindi.Kodwa-ke, esimweni se-voltage ephansi, kungase kube nezinkinga ezithile ekuqaleni kwe-motor, ikakhulukazi ye-motor egijima ekulayisheni.Ukuze kuhlangatshezwane nezidingo ze-motor egijima ekulayisheni, okwamanje kumele kwandiswe, futhi umphumela wokwanda kwamanje kuzoba ukushisa noma ukushiswa kwama-winding, ikakhulukazi ekusebenzeni kwe-low-voltage yesikhathi eside, okuyinto ebucayi nakakhulu.
I-voltage engalingani ye-motor yezigaba ezintathu iyinkinga evamile yokunikezwa kwamandla.Lapho i-voltage ingalingani, nakanjani izoholela ekungeneni kwemoto okungalingani.Ingxenye engalungile yokulandelana kwe-voltage engalingani ikhiqiza insimu kazibuthe esikhaleni somoya semoto ephambene nokuzungeza kwe-rotor.Ingxenye encane yokulandelanisa okunegethivu ye-voltage ingase yenze i-current egeleza endaweni ephendukayo ibe nkulu kakhulu kuneyamanje lapho i-voltage ibhalansisiwe.Imvamisa yamanje egeleza kubha ye-rotor cishe iphindwe kabili imvamisa elinganisiwe, ngakho-ke umphumela wamanje wokucindezela kubha ye-rotor wenza ukulahlekelwa okungeziwe kwenani lokuzungeza kwe-rotor kukhulu kakhulu kunokwe-stator winding.Ukukhuphuka kwezinga lokushisa kwe-stator winding kuphakeme kunalokho kwe-stator esebenza ngaphansi kwe-voltage elinganiselwe.
Lapho i-voltage ingalingani, i-torque ye-rotor ekhiyiwe, i-torque encane kanye ne-torque enkulu ye-motor konke kuzokwehla.Uma ukungalingani kwamandla kagesi kubi kakhulu, injini ngeke isebenze ngokujwayelekile.
Lapho i-motor isebenza ngomthwalo ogcwele ngaphansi kwe-voltage engalingani, ngoba izinga lokushelela likhuphuka ngokunyuka kokulahlekelwa okwengeziwe kwe-rotor, isivinini sizokwehla kancane ngalesi sikhathi.Ngokunyuka kwe-voltage (yamanje) ukungalingani, umsindo nokudlidliza kwemoto kungase kwande.Ukudlidliza kungalimaza injini noma lonke uhlelo lokushayela.
Ukuze kuhlonzwe ngempumelelo izimbangela zokungalingani kwamandla kagesi, kungenziwa ngokutholwa kwamandla kagesi noma ukushintsha kwamanje.Amadivayisi amaningi afakwe amathuluzi okuqapha amandla kagesi, angahlaziywa ngokuqhathanisa idatha.Kulabo abangenawo amadivaysi okuqapha, ukutholwa okuvamile noma ukulinganisa kwamanje kufanele kuthathwe.Kumamotho angakwazi ukuzungeza aye phambili nangemuva, ungashintsha ngokungafanele imigqa yokuphakelwa kwamandla ezigaba ezimbili bese ubheka ukuguqulwa kwamandla, kuyilapho uhlaziya ibhalansi kagesi ngokungaqondile.Ngemva kokuqeda inkinga ye-voltage engalingani, kungase kuhilele izinkinga zekhwalithi ezifana nokujika nokujika kanye nesigaba sesigaba.
