Iimpawu kunye noHlalutyo lweMbangela yeFault yeMotor Overload

Ukugqithiswa kwemoto kubhekisa kwimeko apho amandla okusebenza emoto edlula amandla alinganisiweyo.Xa i-motor igcwele kakhulu, ukusebenza kungoku kulandelayo: i-motor iyatshisa kakhulu, isantya siyehla, kwaye sinokuyeka;imotor inesandi esingavakaliyo esikhatshwa kukungcangcazela okuthile;ukuba umthwalo utshintsha ngokukhawuleza, isantya semoto siya kuguquguquka.

Izinto ezibangela ukugcwala kwemoto ziquka ukungabikho komsebenzi wesigaba, amandla ombane okusebenza angaphezulu kwexabiso elivumelekileyo lombane olinganisiweyo, kwaye isantya semoto siyehla okanye sime ngenxa yokusilela koomatshini.

Ukusebenza okugqithisileyo kwemoto kuya kuchaphazela kakhulu ubomi benkonzo yemoto.Ukubonakaliswa ngokuthe ngqo komthwalo ogqithisiweyo kukuba umsinga we-motor uba mkhulu, okhokelela ekufudumeni okukhulu kwe-motor winding, kunye ne-insulation ejikelezayo iyaguga kwaye ayisebenzi ngenxa yomthwalo ogqithisiweyo wokushisa.

Emva kokuba i-motor ilayishwe kakhulu, inokugwetywa ukusuka kwimeko yokwenyani yokujikeleza.Ukusebenza okuthe ngqo kukuba i-insulation part of the winding imnyama yonke, kwaye umgangatho u-brittle kunye ne-crisp.Kwiimeko ezinzima, inxalenye ye-insulation yonke i-carbonized ibe ngumgubo;Ngokuguga, ifilimu yepeyinti yocingo lwe-enameled iba mnyama, kwaye kwiimeko ezinzima, ikwimeko yokuchithwa okupheleleyo;ngelixa i-mica wire kunye ne-wire-isongelwe ngocingo lwe-electromagnetic, i-insulation layer yahluliwe kwi-conductor.

iimpawu ze-motor windings ezigqithisiweyo ezihluke kakhulu ekulahlekeni kwesigaba, ukujika-ukujika, ukujikeleza komhlaba kunye neempazamo zesigaba ukuya kwisigaba kukuguga kwe-winding ngokubanzi, kunokuba iingxaki zekhwalithi zendawo.Ngenxa yokugqithiswa kwemoto, ingxaki yokufudumala yenkqubo yokuthwala nayo iya kukhutshwa.I-motor enempazamo enkulu iya kukhupha ivumba elibi lokutshisa kwindawo eyingqongileyo, kwaye xa inzima, iya kukhatshwa ngumsi omnyama ongqindilili.

Ingaba luvavanyo lokuhlola okanye uvavanyo lwefektri, ezinye ii-misoperations ngexesha lenkqubo yovavanyo ziya kubangela ukuba i-motor ilayishe kwaye ingaphumeleli.

Ngethuba lokuhlola kunye novavanyo, amakhonkco ajongene nale ngxaki luvavanyo lwe-stall ye-motor kunye ne-wiring kunye ne-pressure application links.Uvavanyo lwe-rotor olumisiweyo yinto esiyibiza ngokuba luvavanyo lwe-short-circuit, oko kukuthi, i-rotor ikwimeko engatshintshiyo ngexesha lovavanyo.Ukuba ixesha lokuvavanya lide kakhulu, i-motor windings iya kutshiswa ngenxa yokushisa;kwimeko yokungonelanga komthamo wezixhobo zovavanyo, ukuba i-motor iqala ixesha elide, oko kukuthi, kwimeko yokukhasa ngesantya esiphantsi esihlala sidibana nayo, ii-motor windings ziya kutshisa kwakhona ngenxa yokutshisa.Ingxaki ehlala isenzeka kwikhonkco le-motor wiring kukudibanisa i-motor ekufuneka iqhagamshelwe yinkwenkwezi ngokwendlela yoqhagamshelo lwe-delta, kwaye ucinezele i-voltage elinganisiweyo ehambelana noqhagamshelo lwenkwenkwezi, kwaye i-motor winding iya kutshisa ngexesha elifutshane. ngenxa yokutshisa;kukwakhona okuqhelekileyo ngokwentelekiso Ingxaki luvavanyo lweemoto ezinamaza ahlukeneyo kunye nombane ohlukeneyo.Abanye abavelisi beemoto okanye abalungisi bokulungisa banombane kuphela ofumaneka rhoqo kwizixhobo zabo zovavanyo.Xa uvavanya ii-motor ezinezandi eziphakamileyo kunamandla amatyeli ombane, ii-windings zihlala zivutha ngenxa yombane ogqithisileyo.

Kuvavanyo lohlobo, uvavanyo lwe-rotor olutshixiweyo lukhonkco oluthambekele ekugqithiseni iimpazamo.Xa kuthelekiswa novavanyo lwefektri, ixesha lovavanyo kunye namanqaku okuqokelela nawo angaphezulu, kwaye ukusebenza kwemoto ngokwayo ayilunganga okanye impazamo yokusebenza kovavanyo nayo ithande ukwenzeka.Ingxaki yokugcwala;Ukongeza, kwinkqubo yovavanyo lomthwalo, ukuba umthwalo awukho ngqiqweni, okanye ukusebenza komthwalo wemoto akwanelanga, kuya kuvela ingxaki yomgangatho ogqithisiweyo wemoto.

Ngokwethiyori, ukuba umthwalo usetyenziswa ngokwamandla alinganisiweyo emoto, ukusebenza kwemoto kukhuselekile, kodwa xa i-voltage yobonelelo lwamandla iphezulu kakhulu okanye iphantsi kakhulu, iya kubangela ukuba ubushushu butshise kwaye buphele. ;ukwanda ngesiquphe komthwalo wemoto kuya kubangela ukuba isantya semoto sinciphe ngesiquphe okanye nokuba Stalling yingxaki eqhelekileyo ngokwentelekiso yomthwalo ogqithisileyo ngexesha lokusebenza, ngakumbi kwimithwalo yempembelelo, kwaye le ngxaki imbi kakhulu.
