Kwindawo enzima yeemoto ezisebenzisa i-induction, isigqibo phakathi kwe-wound rotor kunye ne-squirrel cage rotor sibaluleke kakhulu. Njengoko amashishini avela kumacandelo ahlukeneyo ekhula exhomekeke ngakumbi kwiimoto kwimisebenzi eyahlukeneyo, ukuqonda iingcaciso zezi ntlobo zimbini ze-rotor ezisisiseko kunye nempembelelo yazo ekusebenzeni kweemoto akuyonto iluncedo nje kuphela—yinto eyimfuneko kakhulu.
Ukuvula i-Wound Rotor
Inkcazo kunye noBuchule boYilo
I-wound rotor, edla ngokubizwa ngokuba yi-slip-ring rotor, imele umsebenzi omangalisayo woyilo lobunjineli. Iqulathe isiseko se-rotor apho iingcingo ezigqunyiweyo zijikeleziswa khona, ngokuqhelekileyo kulungiselelo lwezigaba ezintathu, uphawu lwayo olucacileyo lukwikhonkco layo kwisekethe yangaphandle. Olu qhagamshelo lusekwe kusetyenziswa iseti yeeringi zokutyibilika kunye neebhrashi. Iiringi zokutyibilika, iiringi zesinyithi ezibotshelelwe kwishaft ye-rotor, zigcina unxibelelwano lombane oluqhubekayo neebhrashi ezimileyo. Olu seto lwenza ukuba kudityaniswe ii-resistors zangaphandle kwisekethe ye-rotor, uphawu oluchaphazela kakhulu ukusebenza kwemoto.
Iingenelo zokusebenza kunye nezicelo
Enye yezona zinto zibalulekileyo kwi-wound rotor kukuba iyakwazi ukuhambisa i-torque ephezulu yokuqalisa. Xa i-induction motor iqala ukusebenza, umthwalo wokuqala unokuba mkhulu kakhulu. Kwiimeko ezinjalo, i-wound rotor ibonakalisa ixabiso layo. Ngokwandisa ukumelana kwisekethe ye-rotor kusetyenziswa ii-resistors zangaphandle, umsinga wokuqala uyancitshiswa ngelixa i-torque ikhuliswa kakhulu. Oku kwenza ii-wound-rotor motors zilungele ukusetyenziswa ezifuna ukuqaliswa kwemithwalo enzima ukusuka ekumeni, njengakwii-cranes ezinkulu zoshishino. Ezi crane kufuneka ziphakamise imithwalo enzima kakhulu, kwaye i-torque ephezulu yokuqalisa ye-wound-rotor motor iqinisekisa ukusebenza kakuhle nangokutyibilikayo.
Enye into ephawulekayo nge-wound rotor kubuchule bayo bokulawula isantya. Ngokulungisa ukumelana kwisekethe ye-rotor, isantya semoto sinokulungiswa kuyo yonke i-spectrum ebanzi. Oku kuyenza ifaneleke kwizicelo apho isantya kufuneka silungiswe kakuhle ngokweemfuno ezithile zomsebenzi okhoyo. Umzekelo, kwishishini lokwenza iphepha, iimoto eziqhuba oomatshini abaqengqelekayo bephepha zifuna ulawulo oluchanekileyo lwesantya ukuqinisekisa umgangatho wephepha ohambelanayo.
