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 ezinje ngokuguquka kwamaza okutshintsha kunye nokuqalisa ukwehla kuyisombulule ngcono le ngxaki.
Malunga nemotor stall 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.
