Kukho iindidi ezimbini zeemotor zokungeniswa kwe-AC eziqhele ukusetyenziswa kushishino: iimotor zesigaba esinye kunye neemotor zepolyphase.Phakathi kwamaqela e-polyphase, i-motor-phase induction motors isetyenziswa kakhulu.Kwiseti ye-motor yesigaba esisodwa, amaqela angaphantsi amahlanu ahlukeneyo aqhelekileyo asetyenziswa, ahlula-isigaba, i-capacitor-start (i-CS i-variant of motor-phase motor), i-shaded pole (i-shaded pole)), i-capacitor engunaphakade ( I-PSC, i-capacitor ehlala isigxina) kunye ne-capacitor start-capacitor run (i-capacitor start-capacitor run, i-CSCR yinto eyahlukileyo ye-PSC motor).
Ngokuqhelekileyo, inqanaba lokwahlula, i-capacitor-start, kunye ne-capacitor-start capacitor-run motors azibandakanyi kwiimeko zokulawula isantya esiguquguqukayo ngenxa yokuba zonke zinesiqalo sokujikeleza okanye uqhagamshelwano olufuna ukufikelela kwi-75% yesantya esipheleleyo somthwalo we-motor ngaphambi kokuqala. ukujikajika kuqhawulwe, e Xa ulawula isantya, kudla ngokuba ngaphantsi kwama-75%.Ukuba i-starter switch ayivuli, abafowunelwa okanye i-starter winding iya kutshisa ngokukhawuleza kwaye i-motor iya kutshisa kwaye imise.
Xa uthatha isigqibo sokuba zeziphi iinjini zokungeniswa eziza kuzisebenzisa, kukho iindlela zoomatshini ezivumela ezi motor ukuba zifikelele kwisantya esiphezulu, ezinokuthi zisetyenziswe ngokwethiyori ukuba azizange zicothe ngokwaneleyo ukuba ziphinde zibandakanye abafowunelwa bokuqala ngexesha lomsebenzi oqhelekileyo.Eminye i-motor, ipali enomthunzi, i-capacitors ehlala isigxina kunye ne-polyphase, lolona khetho lufanelekileyo lokukhetha imoto eya kulawulwa ngesantya.Imoto yepali enomthunzi yeyona nto inoqoqosho kwezi zintathu ukuba zisetyenziswe ngenxa yoyilo lwayo, kodwa ifumaneka kuphela phantsi kwe-1/4 yamandla ehashe.Ikwanayo ne-torque ephantsi yokuqala kunye ne-torque kwaye ayisebenzi kakuhle ngenxa yemida.Ngoko ke, ekusebenzeni kwesigaba esisodwa esinamandla angaphezu kwe-1/4 kunye / okanye i-torque ephezulu yokusebenza, i-motor capacitor ehlala isigxina isoloko isetyenziswa.Olu hlobo lwenjini yenye yeenjini zesigaba esinye ezibiza kakhulu, kodwa zithembeke kakhulu, zikwazi ukubaleka kakuhle nokuqalisa, kwaye zivumela isantya ukuba silawulwe ngekhompyutha.Iimotor zecapacitor ezahlulwe ngokusisigxina zisebenza kufutshane nenqanaba lesithathu lemotor.indlela yokusebenza.
Iinjini zamanqanaba amathathu ziyafumaneka kwinxalenye kunye namandla apheleleyo ehashe, kodwa ngokubanzi, ukongiwa kwamandla akuyi kudlula iindleko zazo de zingene kuluhlu lwamandla ehashe ngokubanzi.Isebenza ngokusisiseko ngendlela efanayo nenqanaba elinye lemoto, hayi intambo enye eshushu, kodwa ezintathu, isantya solawulo kufuneka sihluke kumlawuli wesigaba esinye, kwaye imisebenzi yenqanaba elinye kunye nenqanaba lesithathu lihluke kancinci.
Kukho iindlela ezine ngokubanzi zokulawula isantya senjini.Eyona ilula yinjini yesantya esiguqukayo.Amaqela amathathu aseleyo lulawulo lwesantya sesixhobo, ulawulo oluluqilima kunye nezixhobo zoomatshini.Indlela nganye yodwa kwaye ifumaneka kulo lonke ishishini.sebenzisa.Nokuba sisiphi na isicelo, jonga ngokubanzi kumenzi wemoto ukuba uthini umgangatho wolawulo lwesantya, njengoko ezinye iinjini azixhotyiselwanga ukulawula isantya.Kwakhona, qaphela zonke iinkxalabo zokhuseleko ezifana nokukhuselwa kwe-thermal overload njengenxalenye yenkqubo yokulawula isantya.Ngokuqhelekileyo kukho ubushushu obuninzi obuveliswa yimoto, xa usebenzisa umlawuli wesantya, ukukhusela iingozi okanye umonakalo, kucetyiswa ukuba umkhuseli ogqithisiweyo unokuba yinxalenye yemoto okanye umlawuli ngokwawo.
ukuququmbela
Njengokusetyenziswa kweiinjini zoshishinoiye yavela kwiminyaka, ngoko ke baneendlela zokulawula isantya, ukufumana ukhetho olufanelekileyo lokulawula isantya, luhlobo luni lwemoto enokuthi luyithathe, kunye neendleko / izithintelo zobuchule ezibandakanyekayo, abanye abalawuli banokungabizi kakhulu, Hayi njengomsebenzisi onobungane. njengabanye abalawuli, kodwa uyawenza umsebenzi.
