Injinii-shaft ilungisiwe ukwenzela ukuba ingajikelezi, kwaye i-current inamandla.Ngeli xesha, yangoku yi-rotor yangoku evaliweyo.Iinjini ze-AC ngokubanzi, kubandakanywa iimotho zokumodareyitha rhoqo, azivumelekanga ukuba zime.Ngokophawu lwangaphandle lwe-AC motor, xa i-AC motor itshixiwe, "i-subversion current" iya kuveliswa ukutshisa i-motor.
I-current-rotor current kunye neyokuqala yangoku ilingana nexabiso, kodwa ubude bemoto yokuqala yangoku kunye ne-rotor evaliweyo yangoku iyahluka.Ixabiso eliphezulu lexesha lokuqala livela ngaphakathi kwe-0.025 emva kokuba i-motor iqhutywe, kwaye ibola ngokukhawuleza ngokuhamba kwexesha., isantya sokubola sinxulumene nexesha elingaguqukiyo lemoto;ngelixa i-rotor yangoku ye-motor ingaboli ngokuhamba kwexesha, kodwa ihlala ingatshintshi.
Ukusuka kuhlalutyo lwemeko yemoto, sinokuyahlula ibe ngamazwe amathathu: ukuqala, ukusebenza okulinganiselweyo kunye nokuvalwa.Inkqubo yokuqala ibhekisa kwinkqubo yokutshintsha i-rotor ukusuka kwi-static ukuya kwisantya esilinganiselweyo xa i-motor inamandla.
Malunga nemoto eqala ngoku
Isiqalo sangoku sihambelana nokutshintsha kwe-rotor ukusuka kwi-static state ukuya kwimeko eqhubayo ngeli xesha xa i-motor inikwe amandla phantsi kwemeko ye-voltage elinganisiweyo.Yinkqubo yokutshintsha imo yokunyakaza ye-motor rotor, oko kukuthi, ukutshintsha inertia ye-rotor, ngoko ke umbane ohambelanayo uya kuba mkhulu.Xa uqala ngokuthe ngqo, i-current current ye-motor ngokuqhelekileyo i-5 ukuya kwi-7 yamaxesha angoku.Ukuba isiqalo sangoku semoto sikhulu kakhulu, siya kuba nefuthe elibi kakhulu kumzimba wemoto kunye negridi yamandla.Ke ngoko, kwiinjini ezinkulu kunye neziphakathi, ukuqala kwangoku kuya kukhawulelwa malunga namaxesha ama-2 angoku alinganiselweyo ngokuqala okuthambileyo.Uphuculo oluqhubekayo lwenkqubo yokulawula iimoto kunye neendlela ezahlukeneyo zokuqalisa ezinjengokuqala okuguquguqukayo kunye nokwehla kwenqanaba lokuqala kuyisombulule ngcono le ngxaki.
Malunga nemoto yokumisa yangoku
Ngokwenyani, kunokuqondwa ukuba i-rotor yangoku itshixiwe ngumlinganiselo wangoku xa i-rotor igcinwa imile, kwaye i-rotor itshixiwe yimeko apho i-motor isakhupha i-torque xa isantya singu-zero, esiqhelekileyo sinomatshini okanye sisenziwa.
Xa i-motor igcwele kakhulu, oomatshini abaqhutywayo bayasilela, ukuthwala konakalisiwe, kwaye i-motor inokusilela kakhulu, i-motor ayinakukwazi ukujikeleza.Xa i-motor itshixiwe, amandla ayo aphantsi kakhulu, kwaye i-rotor yangoku itshixiwe inkulu, kwaye i-motor winding inokutshiswa ixesha elide.Nangona kunjalo, ukuze uvavanye ukusebenza kwemoto, kuyimfuneko ukwenza uvavanyo lwe-stall kwi-motor, oluqhutyelwa kuzo zombini uhlobo lovavanyo kunye nokuhlolwa kwemoto.
Uvavanyo lwe-rotor oluvaliweyo luyi-locked current ukulinganisa i-rotor evaliweyo yangoku, ixabiso le-torque evaliweyo kunye nokulahleka kwe-rotor evaliweyo kwi-voltage elinganisiweyo.Ngokuhlalutya i-current-rotor current kunye ne-balance yesigaba sesithathu, inokubonakalisa i-stator kunye ne-rotor windings ye-motor, kunye ne-stator kunye ne-rotor.Ingqiqo yesekethe yamagnetic eyenziweyo kunye neengxaki ezithile zomgangatho.
Ngexesha lovavanyo lohlobo lwemoto, kukho amanqaku ombane amaninzi alinganiswa ngovavanyo lwerotor etshixiweyo.Xa i-motor ivavanywa kumzi-mveliso, indawo yombane iya kukhethwa ukulinganisa.Ngokubanzi, umbane wovavanyo ukhethwa ngokwesine ukuya kwisinye kwisihlanu sombane olinganisiweyo wemoto, njengaxa umbane olinganisiweyo uyi-220V, i-60V ikhethwe ngokufanayo njengombane wovavanyo, kwaye xa umbane olinganisiweyo uyi-380V, I-100V ikhethwe njengombane wovavanyo.
