Ukugcwala kwemotor kusho isimo lapho amandla angempela okusebenza enjini edlula amandla alinganiselwe. Lapho i-motor igcwele kakhulu, ukusebenza kungokulandelayo: i-motor ishisa kakhulu, ijubane liyehla, futhi lingase lime; injini inomsindo ongacacile ohambisana nokudlidliza okuthile; uma umthwalo ushintsha kakhulu, ijubane lemoto lizoguquguquka .
Izimbangela zokugcwala kwezimoto zihlanganisa ukungasebenzi kwesigaba, amandla ogesi okusebenza adlula inani elivumelekile le-voltage elinganiselwe, futhi isivinini semoto siyehla noma sime ngenxa yokwehluleka kwemishini.
Ukusebenza okugcwele kwenjini kuzothinta kakhulu impilo yesevisi yemoto. Ukubonakaliswa okuqondile komthwalo omningi ukuthi amandla amanje enjini ayanda, okuholela ekushiseni okungathí sina kwe-motor winding, futhi i-insulation emazombezombe iyaguga futhi ayivumelekile ngenxa yomthwalo omkhulu wokushisa.
Ngemuva kokuthi i-motor igcwele ngokweqile, ingahlulelwa kusukela esimweni sangempela sokusonga. Ukusebenza okuqondile ukuthi ingxenye yokufakwa kwama-winding yonke imnyama, futhi ikhwalithi iyashwabana futhi icwebile. Ezimweni ezimbi kakhulu, ingxenye yokufakelwa yonke i-carbonized ibe yimpushana; Ngokuguga, ifilimu yopende yocingo olunamele iba mnyama, futhi ezimweni ezinzima, isesimweni sokuchithwa okuphelele; kuyilapho i-mica wire kanye ne-electromagnetic insulated eboshwe ngocingo, isendlalelo sokufakwa kwe-insulation sihlukanisiwe ne-conductor.
izici ze-motor windings ezigcwele ngokweqile ezihlukile ekulahlekeni kwesigaba, ukuphenduka, ukuphenduka phansi, phansi kuya phansi kanye nesigaba-to-isigaba amaphutha ukuguga kokusonteka sekukonke, kunezinkinga zekhwalithi yendawo.Ngenxa yokugcwala kwe-motor, inkinga yokushisa yesistimu yokuthwala nayo izotholakala.Injini enephutha eligcwele kakhulu izokhipha iphunga elibi lokushiswa endaweni ezungezile, futhi uma lishubile, lizohambisana nentuthu emnyama ewugqinsi.
Kungakhathaliseki ukuthi ukuhlolwa kokuhlola noma ukuhlolwa kwefekthri, okunye ukungalungi ngesikhathi senqubo yokuhlola kuzobangela ukuthi injini igcwale kakhulu futhi ihluleke.
Ngesikhathi sokuhlolwa nokuhlolwa, izixhumanisi ezithambekele kule nkinga ukuhlolwa kwe-stall ye-motor kanye nezixhumanisi ze-wiring ne-pressure application.Ukuhlolwa kwe-rotor okumile yilokho esikubiza ngokuthi ukuhlolwa kwe-short-circuit, okungukuthi, i-rotor isesimweni esimile ngesikhathi sokuhlolwa. Uma isikhathi sokuhlola siside kakhulu, ama-motor windings azoshiswa ngenxa yokushisa ngokweqile; esimweni somthamo onganele wemishini yokuhlola, uma injini iqala isikhathi eside, Okusho ukuthi, esimweni sokukhasa ngesivinini esiphansi esivame ukuhlangana naso, ama-motor windings nawo azoshisa ngenxa yokushisa ngokweqile.Inkinga evame ukwenzeka kusixhumanisi se-motor wiring iwukuxhuma injini okufanele ixhunywe inkanyezi ngokwendlela yokuxhuma i-delta, bese ucindezela i-voltage elinganiselwe ehambisana nokuxhuma kwenkanyezi, futhi ukuvuthwa kwemoto kuzosha ngesikhathi esifushane. ngenxa yokushisa ngokweqile; kukhona futhi okujwayelekile okujwayelekile Inkinga ukuhlolwa kwamamotho anamaza ahlukene kanye nama-voltages ahlukene. Abanye abakhiqizi bezimoto noma abakhiqizi bokukhanda banamandla okuvama kagesi kuphela ezinsizeni zabo zokuhlola. Uma uhlola amamotho anefrikhwensi ephezulu kunamandla efrikhwensi yamandla, ama-winding ngokuvamile azosha ngenxa ye-voltage eyeqile.
Kuhlolo lohlobo, ukuhlolwa kwerotha ekhiyiwe kuyisixhumanisi esithambekele ekulayisheni ngokweqile amaphutha. Uma kuqhathaniswa nokuhlolwa kwefekthri, isikhathi sokuhlola kanye namaphuzu okuqoqwa nawo angaphezulu, futhi ukusebenza kwemoto ngokwayo akukuhle noma iphutha lokusebenza kokuhlola nalo livame ukwenzeka. Inkinga yokulayisha ngokweqile; Ngaphezu kwalokho, ngenqubo yokuhlola umthwalo, uma umthwalo kungenangqondo, noma ukusebenza komthwalo wemoto akwanele, inkinga yekhwalithi yokulayisha ngokweqile izovela.
Ngokwethiyori, uma umthwalo usetshenziswa ngokwamandla alinganisiwe emoto, ukusebenza kwemoto kuphephile, kepha lapho i-voltage yomthombo wamandla iphezulu kakhulu noma iphansi kakhulu, izobangela ukuthi i-winding ishise futhi iphele. ; ukwanda okungazelelwe komthwalo wemoto kuzobangela ukuthi ijubane lemoto lehle ngokuzumayo noma i-Stalling iyinkinga evamile yokulayisha ngokweqile ngesikhathi sokusebenza, ikakhulukazi emithwalweni yomthelela, futhi le nkinga inkulu kakhulu.
