Kwimveliso yemizi-mveliso yanamhlanje, iimoto zombane zisetyenziswa kakhulu. Iintlobo ezahlukeneyo, iifom zevolthi kunye namanqanaba evolthi yeemoto zombane zivela ngokungenasiphelo. Oku kulandelayo yingcaciso emfutshane yezizathu zokusebenza kwesigaba esinye kunye namanyathelo okuthintela.
Ulwahlulo lweemoto
Iimoto zombane zinokwahlulwa zibe ziimoto zeDC, iimoto ezingasebenziyo kunye neemoto ezihambelanayo ngokwezakhiwo ezahlukeneyo kunye nemigaqo yokusebenza. Iimoto ezihambelanayo zinokwahlulwa zibe ziimoto ezihlala zihleli ezihambelanayo zemagnethi, iimoto ezingasebenziyo ezingafuniyo kunye neemoto ezihambelanayo zehysteresis. Iimoto ezingasebenziyo zinokwahlulwa zibe ziimoto ezisetyenziswayo kunye neemoto ze-AC commutator. Iimoto ezisetyenziswayo zahlulwa zibe ziimoto ezingasebenziyo zesigaba sesithathu, iimoto ezingasebenziyo zesigaba esinye kunye neemoto ezingasebenziyo zepole ezinombala. Iimoto ezisetyenziswayo ze-AC zahlulwa zibe ziimoto ezisetyenziswayo zesigaba esinye,Iimoto ze-AC kunye ne-DC ezinjongo zimbini kunye neemoto ezigxothayo.
Iingozi ezibangelwa kukusebenza kwesigaba esinye seemoto ezingasebenziyo ezinamanqanaba amathathu
Iimoto ezingasebenziyo ezinamanqanaba amathathu zineendlela ezimbini zokuxhuma: uhlobo lwe-Y kunye nohlobo lwe-Δ. Xa imoto eqhagamshelwe yi-Y isebenza kwisigaba esinye, umbane kwisigaba esiqhagamshelweyo ngu-zero. Imisinga yesigaba sezinye izigaba ezibini iba yimisinga yomgca. Kwangaxeshanye, iya kubangela ukushukuma kwe-zero point kwaye umbane wayo wesigaba uya kwanda.
Xa i-motor enentambo yohlobo lwe-Δ iqhagamshelwe ngaphakathi, i-motor itshintsha ibe yintambo yohlobo lwe-V phantsi kwesenzo sombane wesigaba sesithathu, kwaye umsinga wesigaba sesibini uyanda ngamaxesha ali-1.5. Xa i-motor enentambo yohlobo lwe-Δ iqhagamshelwe ngaphandle, ilingana nee-windings zesigaba sesibini eziqhagamshelwe ngokulandelelana kwaye iqela lesithathu le-windings liqhagamshelwe ngaxeshanye phakathi kwe-voltages zemigca emibini. Umsinga kwisibiniiiwindingsiqhagamshelwe kuthotho ayitshintshanga. Umbane owongezelelweyo weqela lesithathu uza kwandiswa ngamaxesha ali-1.5.
Ngamafutshane, xa injini isebenza kwisigaba esinye, umsinga wayo wokujika uyanda ngokukhawuleza, kwaye isigqubuthelo sokujika kunye nesinyithi sishushu ngokukhawuleza, sitshisa i-insulation yokujika size sitshise i-motor winding, nto leyo echaphazela imisebenzi eqhelekileyo yemveliso. Ukuba imeko yendawo ayilunganga, imeko-bume ejikelezileyo iya kuqokelelana. Kukho izinto ezinokutsha ezinokubangela umlilo ngokulula kwaye zibangele iziphumo ezibi ngakumbi.
Izizathu zokusebenza kwe-motor yesigaba esinye kunye namanyathelo okuthintela
1.Xa i-motor ingakwazi ukuqala, kukho isandi esirhabaxa, kwaye iqokobhe linyuke ubushushu okanye isantya siyancipha kakhulu ngexesha lokusebenza, kwaye ukunyuka kobushushu kuyanda, umbane kufuneka unqunyulwe ngoko nangoko kwaye unobangela wokungasebenzi kakuhle kufuneka ufunyanwe ngononophelo. Qinisekisa ukuba imeko engentla ibangelwa kukungabikho kwesigaba.
2.Xa umgca wamandla wesekethe ephambili ubhityile kakhulu okanye ujongene nomonakalo wangaphandle, umbane wesigaba esithathu semoto uya kubangela ukusebenza kwesigaba esinye ngenxa yokutsha kwesigaba okanye ukubetha kwamandla angaphandle. Umthamo wokuthwala okhuselekileyo womgca wamandla oyintloko wemoto uphindwe kayi-1.5 ukuya kwi-2.5 kunombane olinganisiweyo wemoto, kwaye umthamo wokuthwala okhuselekileyo womgca wamandla unxulumene ngokusondeleyo nendlela yokubeka umgca wamandla. Ingakumbi xa ihambelana okanye idibana nombhobho wobushushu, isithuba kufuneka sibe ngaphezu kwama-50cm. Umthamo wokuthwala okhuselekileyo wentambo yamandla onokusebenza ixesha elide kwi-70°C ukunyuka kobushushu ngokubanzi unokuhlolwa yincwadi yemiyalelo yombane. Ngokwamava angaphambili, umthamo wokuthwala okhuselekileyo weentambo zobhedu yi-6A nge-milimitha yesikwere, kwaye lowo weentambo ze-aluminium yi-4A nge-milimitha yesikwere. Ukongeza, kufuneka kusetyenziswe amalungu okutshintshana kobhedu-aluminium xa kudibana ucingo lwethusi-aluminium, ukuze kuthintelwe ukuxinana phakathi kwezinto zobhedu-aluminium kwaye kuchaphazele ukumelana kwamalungu.
3. Uqwalaselo olungalunganga lweswitshi yomoya okanye isithinteli sokuvuza lunokubangela ukusebenza kwemoto ngesigaba esinye. Ukuba uqwalaselo lweswitshi yomoya luncinci kakhulu, kusenokuba kungenxa yokuba umbane wamandla mkhulu kakhulu ukuba ungatshisa oonxibelelwano bangaphakathi beswitshi yomoya, nto leyo ebangela ukuba ukumelana noqhagamshelwano lwesigaba kukhulu kakhulu, okwenza ukusebenza kwemoto yesigaba esinye. Umlinganiselo wamandla otshintshi yomoya kufuneka ube yi-1.5 ukuya kwi-2.5 ngokuphindwe kabini kunomlinganiselo wamandla otshintshi wemoto. Ukongeza, ngexesha lokusebenza kwemoto, kufuneka kujongwe ukuba umlinganiselo weswitshi yomoya uncinci kakhulu, okanye umgangatho weswitshi yomoya ngokwawo unengxaki, kwaye kufuneka kutshintshwe iswitshi yomoya efanelekileyo.
4. Umgca woqhagamshelo phakathi kwezinto ezikwikhabhinethi yokulawula uyatsha, nto leyo enokubangela ukuba imoto isebenze kwisigaba esinye. Izizathu zokutsha komgca woqhagamshelo zezi zilandelayo:
① Umgca woqhagamshelo ubhityile kakhulu, xa umbane we-motor overload unyuka, unokutshisa umgca woqhagamshelo. ② Izihlanganisi kuzo zombini iziphelo zomgca woqhagamshelo azihambelani kakuhle, nto leyo ebangela ukuba umgca woqhagamshelo ushushu kakhulu, nto leyo etshisa umgca woqhagamshelo. Kukho umonakalo omncinci kwizilwanyana, njengokunyuka kweempuku phakathi kwemigca emibini, okubangela umjikelo omfutshane phakathi kwemigca kunye nokutshisa umgca woqhagamshelo. Isisombululo sesi: ngaphambi kokuqala umsebenzi ngamnye, ikhabhinethi yokulawula kufuneka ivulwe ukuze kujongwe ngononophelo ukuba umbala womgca ngamnye woqhagamshelo utshintshile na, kwaye ingaba ulusu lobushushu luneempawu zokutsha na. Umgca wombane uxhotyiswe ngokufanelekileyo ngokomthamo womthwalo wemoto, kwaye isihlanganisi siqhagamshelwe ngokweemfuno zenkqubo.
Ukuguqulwa
Ekwakhiweni, kufuneka silandele ngokungqongqo imiqathango yeenkqubo ezahlukeneyo zokwakha ukuqinisekisa umgangatho wokufakelwa. Ukugcinwa rhoqo kwezixhobo ezahlukeneyo kunye nokuhlolwa rhoqo kunye nokulungiswa ngexesha lokusebenza ngokuqinisekileyo kuya kuthintela ilahleko ezingeyomfuneko kunye neengozi ezibangelwa kukusebenza kwenjini kwinqanaba elinye.
