Kutheni ezi ngxaki zihlala zisenzeka kwii-rotor motor?

Kwiimeko zokungaphumeleli kweemveliso zeemoto, inxalenye ye-stator ibangelwa kakhulu kukujikeleza. Inxalenye ye-rotor inokwenzeka ukuba ibe ngoomatshini. Kwi-rotors yamanxeba, oku kubandakanya ukusilela okujikelezayo.

Xa kuthelekiswa neenjini ze-rotor zenxeba, i-aluminium rotors ephosiweyo ayinakukwazi ukuba neengxaki, kodwa emva kokuba ingxaki ivele, yingxaki enkulu ngakumbi.

Okokuqala, ngaphandle ukhuseleko overspeed, inxeba rotor kusenokwenzeka ukuba iphakheji drop ingxaki, oko kukuthi, ekupheleni rotor ukujikoza kakhulu radially deformed, nto leyo enokwenzeka kakhulu ukuphazamisa ekupheleni stator ukujikoza, uze ubangele. yonke imotor iyajika iphele kwaye ijam ngoomatshini. Ke ngoko, isantya serotor yenxeba asinakuba phezulu kakhulu, kwaye isantya esihambelanayo siqhele ukuba yi-1500 rpm okanye ngaphantsi.

Kutheni ezi ngxaki zihlala zisenzeka kwii-rotor motor?

Okwesibini, i-rotor ye-aluminium ephosiweyo ineengxaki zendawo okanye zokufudumeza ngokubanzi. Ukuba akukho ngxaki kuyilo, ngakumbi ngenxa yokuba inkqubo ye-aluminium ephosiweyo ayihambelani noyilo, i-rotor ineentsimbi ezinzulu ezaphukileyo okanye ezibhityileyo, kwaye i-motor inokufudumala kwendawo okanye enkulu xa isebenza. Kwiimeko ezinzima, i-rotor surface ijika eluhlaza okwesibhakabhaka, kwaye kwiimeko ezinzima kakhulu, ukuhamba kwe-aluminium kwenzeka.

Okwesithathu, kwii-rotors ezininzi ze-aluminium eziphosiweyo, iziphelo zizinzile. Nangona kunjalo, ukuba uyilo alunangqiqo, okanye kukho iimeko ezinjengoxinzelelo oluphezulu lwangoku kunye nokunyuka kweqondo lokushisa eliphezulu, iziphelo ze-rotor nazo zinokuba neengxaki ezifana ne-rotor ejikelezayo, oko kukuthi, ii-wind blades eziphelweni zikhubazeke kakhulu. Le ngxaki ixhaphake kakhulu kwiinjini ezimbini zeepali, kwaye ngokuqinisekileyo inxulumene ngokuthe ngqo nenkqubo yokuphosa i-aluminium. Enye ingxaki enkulu kukuba i-aluminiyam inyibilika ngokuthe ngqo, ezinye zazo zenzeke kwiindawo zokubeka i-rotor, kwaye ezinye zenzeke kwi-rotor end ring position. Ukuthetha ngeenjongo, xa le ngxaki isenzeka, kufuneka ihlalutywe ukusuka kwinqanaba loyilo, kwaye ke inkqubo yokuphosa i-aluminium kufuneka ivavanywe ngokupheleleyo.

Xa kuthelekiswa nenxalenye ye-stator, ngenxa yobume obukhethekileyo be-rotor ekuhambeni, kufuneka ihlolwe ngokwahlukileyo kumanqanaba omatshini kunye nombane, kwaye ukuqinisekiswa kokusebenza okufunekayo kufuneka kwenziwe.
