Vim li cas cov teeb meem no ib txwm tshwm sim ntawm lub cev muaj zog rotors?

Hauv qhov tsis ua hauj lwm ntawm cov khoom siv lub cev muaj zog, qhov stator feem ntau yog tshwm sim los ntawm kev winding. Qhov rotor feem ntau yuav yog txhua yam. Rau qhov txhab rotors, qhov no kuj suav nrog winding tsis ua haujlwm.

Piv nrog rau lub qhov txhab rotor motors, cam khwb cia txhuas rotors tsis tshua muaj teeb meem, tab sis thaum muaj teeb meem tshwm sim, nws yog ib qho teeb meem loj dua.

Ua ntej, tsis muaj kev tiv thaiv overspeed, lub qhov txhab rotor feem ntau yuav muaj teeb meem ntawm pob poob, uas yog, qhov kawg ntawm lub rotor winding yog deformed heev radially, uas yog heev yuav cuam tshuam qhov kawg ntawm stator winding, thiab tom qab ntawd ua rau. tag nrho lub cev muaj zog winding kom hlawv tawm thiab mechanically jam. Yog li ntawd, qhov ceev ntawm lub qhov txhab rotor lub cev muaj zog tsis tuaj yeem siab dhau, thiab qhov ceev synchronous feem ntau yog 1500 rpm lossis tsawg dua.

Vim li cas cov teeb meem no ib txwm tshwm sim ntawm lub cev muaj zog rotors?

Qhov thib ob, cov cam khwb cia txhuas rotor muaj teeb meem hauv zos lossis tag nrho cov cua sov. Yog tias tsis muaj teeb meem nrog kev tsim, nws yog ntau dua vim tias cov txheej txheem txhuas cam khwb cia tsis ua raws li tus qauv tsim, lub rotor muaj qhov tawg loj lossis nyias nyias, thiab lub cev muaj zog muaj cua sov hauv zos lossis txawm tias loj thaum khiav. Hauv qhov xwm txheej hnyav, lub rotor nto tig xiav, thiab nyob rau hauv cov xwm txheej hnyav dua, txhuas ntws tshwm sim.

Thib peb, rau feem ntau cam khwb cia txhuas rotors, qhov kawg yog qhov ruaj khov. Txawm li cas los xij, yog tias tus qauv tsim tsis tsim nyog, lossis muaj cov xwm txheej xws li qhov siab tam sim no thiab qhov kub thiab txias siab, lub rotor kawg kuj tseem muaj teeb meem zoo ib yam li lub rotor winding, uas yog, cov cua ntawm qhov kawg yog deformed heev radially. Qhov teeb meem no muaj ntau dua nyob rau hauv ob-ncej motors, thiab tau kawg nws yog ncaj qha ntsig txog cov txheej txheem txhuas casting. Lwm qhov teeb meem loj yog tias cov txhuas yog ncaj qha melted, qee qhov tshwm sim hauv rotor slots, thiab qee qhov tshwm sim ntawm rotor kawg lub nplhaib txoj hauj lwm. Lub hom phiaj hais lus, thaum qhov teeb meem no tshwm sim, nws yuav tsum tau soj ntsuam los ntawm cov qauv tsim, thiab tom qab ntawd cov txheej txheem aluminium casting yuav tsum tau soj ntsuam tag nrho.

Piv nrog rau ib feem ntawm stator, vim qhov tshwj xeeb ntawm lub rotor nyob rau hauv cov lus tsa suab, nws yuav tsum tau soj ntsuam cais los ntawm cov neeg kho tshuab thiab hluav taws xob theem, thiab yuav tsum tau ua raws li qhov tsim nyog kev soj ntsuam xyuas.
