Nayiphi na imveliso yombane, kubandakanywa iimveliso zemoto, ngokuqinisekileyo, ichaza umbane olinganisiweyo ngokusebenza kwayo kwesiqhelo.Nakuphi na ukutenxa kombane kuya kubangela iziphumo ezibi ekusebenzeni okuqhelekileyo kwesixhobo sombane.

Kwizixhobo eziphezulu, izixhobo eziyimfuneko zokukhusela zisetyenziswa.Xa i-voltage yonikezelo lwamandla ingaqhelekanga, ukunikezelwa kombane kunqunyulwa ukukhusela.Kwizixhobo ezichanekileyo, unikezelo lwamandla ombane rhoqo lusetyenziselwa ukulungiswa.Iimveliso zeemoto, ngakumbi kwiimveliso zeemoto zemizi-mveliso, ukubanakho ukusebenzisa isixhobo sombane esingaguqukiyo sincinci kakhulu, kwaye kukho iimeko ezininzi zokukhusela umbane.

Kwinqanaba elinye lemoto, kukho iimeko ezimbini kuphela zombane ophezulu kunye nombane ophantsi, ngelixa i-motor yesigaba sesithathu, kukho ingxaki ye-voltage balance.Ukubonakaliswa okuthe ngqo kwempembelelo yale miqobo mithathu yombane kukunyuka kwangoku okanye ukungalingani kwangoku.

Iimeko zobugcisa zemoto zichaza ukuba ukuphambuka okuphezulu kunye nangaphantsi kwe-voltage elinganisiweyo ye-motor ayikwazi ukudlula i-10%, kwaye i-torque ye-motor ilingana nesikwere se-motor terminal voltage.Xa i-voltage iphezulu kakhulu, i-iron core ye-motor iya kuba kwimeko ye-saturation magnetic, kwaye i-stator yangoku iya kwanda.Kuya kukhokelela ekufudumeni okunzulu kwe-winding, kunye nengxaki yomgangatho wokutshisa okutshisayo;kwaye kwimeko ye-voltage ephantsi, enye kukuba kunokubakho iingxaki ngokuqala kwe-motor, ngakumbi kwi-motor esebenza phantsi komthwalo, ukuze ihlangabezane nomthwalo osebenzayo we-motor, i-current kufuneka yandiswe, kwaye isiphumo sokunyuka kwangoku kwakhona kukufudumeza kunye nokutshiswa kwee-windings, ngakumbi kwi-long-term low-voltage operation, ingxaki inzima kakhulu.

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 engalinganiyo lidala intsimi yamagnetic kwi-gap yomoya wemoto echasa ukujika kwe-rotor.Inxalenye encinci yolandelelwano olubi kumbane inokubangela ukuba umsinga ngokujija ube mkhulu kakhulu kunaxa umbane ulungelelanisiwe.I-frequency yangoku equkuqelayo kwimivalo ye-rotor iphantse iphindwe kabini i-frequency rated frequency, ngoko ke umphumo wangoku wokucudisa kwii-rotor bars wenza ukulahleka kokunyuka kwee-rotor windings kukhulu kakhulu kunoko kwe-stator windings.Ukunyuka kweqondo lokushisa kwe-stator winding kuphezulu kunoko xa usebenza kwi-voltage elinganayo.

Xa i-voltage ingalingani, i-torque ye-stall, i-torque encinci kunye ne-torque ephezulu ye-motor iya kuncitshiswa.Ukuba ukungalingani kwamandla ombane kunzulu, i-motor ayiyi kusebenza kakuhle.

Xa i-motor isebenza ngomthwalo opheleleyo phantsi kwe-voltage engalinganiyo, ekubeni i-slip inyuka ngokunyuka kokulahleka okongeziweyo kwe-rotor, isantya siya kuncipha kancinci ngeli xesha.Njengoko i-voltage (yangoku) ingalingani inyuka, ingxolo kunye nokungcangcazela kwemoto kunokunyusa.Ukungcangcazela kungonakalisa imotor okanye inkqubo yonke yokuqhuba.

Ukuze uchonge ngokufanelekileyo unobangela wombane wemoto ongalinganiyo, unokuthi uqhutywe ngendlela yokufumanisa umbane wombane okanye ukuhluka kwangoku.Uninzi lwezixhobo zixhotyiswe ngesixhobo sokubeka iliso sombane, esinokuhlalutywa ngokuthelekisa idatha.Kwimeko apho kungekho sixhobo sokubeka iliso, ukufumanisa rhoqo okanye umlinganiselo wangoku kufuneka usetyenziswe.Kwimeko yokutsala izixhobo, umgca wesigaba sesibini sombane unokutshintshwa ngokungaqhelekanga, utshintsho lwangoku lunokubonwa, kwaye ibhalansi yombane inokuhlalutywa ngokungathanga ngqo.
