Ukususela kuhlalutyo lwamazwe amabini anengqiqo yokungabikho komthwalo kunye nomthwalo, unakongokusisiseko kuqwalaselwe ukuba phantsi komthwalo wemo yemoto, ngenxa yokuba idonsa umthwalo, iya kuhambelana nomsinga omkhulu, oko kukuthi, umthwalo wangoku wemoto uya kuba mkhulu kunomthwalo wangoku;kodwa okuLe meko ayisebenzi kuzo zonke iinjini, oko kukuthi, ezinye iinjini azinamthwalo wangoku omkhulu kunomthwalo wazo wangoku.
Kukho imisebenzi emibini yombane yengxenye ye-stator ye-asynchronous motor: enye kukufaka amandla ombane, kwaye enye kukuseka intsimi yamagnetic ejikelezayo yemoto.
Kwimeko yokungabikho komthwalo we-motor, icandelo langoku liyi-excitation current, kwaye i-current esebenzayo ehambelana nokulahlekelwa komthwalo kuncinci.Oko kukuthi, igalelo lamandla ombane lincinci kwi-no-load, kwaye i-stator yangoku isetyenziselwa ukuseka intsimi yamagnetic.
Kwimeko yomthwalo, amandla amaninzi kufuneka abe negalelo lokuqhuba umthwalo.Ngokuqhelekileyo, icandelo langoku ngokuyintloko ngumthwalo wangoku, ngoko ke umthwalo wangoku udla ngokuba mkhulu kunomthwalo okhoyo, kwaye akukho mthwalo wangoku kuphela kwe-1/4 ukuya kwi-1/2 yomthwalo wangoku.phakathi.
Ukuguqulwa kwamandla e-electromechanical ngaphakathi kwemoto yinkqubo enzima kakhulu.Ukusekwa kommandla wemagnethi njengokuphela kwendlela yokuguqula i-electromechanical kubandakanya izinto ezahlukeneyo, ezikhokelela kwinto yokuba akukho mthwalo wangoku woyilo oluthile okanye iindidi zeenjini mkhulu kunomthwalo wangoku.
Kwinqanaba lesithathu le-asynchronous motor, i-wind-phase windings isasazwa ngokulinganayo kwindawo, kwaye igalelo lesigaba sesithathu sangoku silingana.Kunokuba ube nesiqhelo esithile.Nangona kunjalo, kwezinye iimoto eziyilwe ngokukodwa, ezinje ngepali enye etshintsha isantya semoto enesantya esithile okanye inani leepali, ukusabela okuvuzayo okanye ukuvuza kukhulu kakhulu, kunye nokuhla kwamandla ombane okuvuza okubangelwa ngumthwalo. yangoku inkulu, ibangele inqanaba lokuzalisa isekethe yamagnetic phantsi komthwalo.Isezantsi kakhulu kunokungathwali mthwalo, umthamo wokuvuselela umthwalo uncinci kakhulu kunomthwalo okhoyo wokuvuselela amandla, okubangela ukuba akukho mthwalo wangoku omkhulu kunomthwalo wangoku.
I-magnetic field ye-motor-phase-motor yi-elliptical magnetic field, kwaye i-ellipticity ihluke phakathi kokungabikho komthwalo kunye nomthwalo, kwaye kaninzi unomahluko omkhulu.Ngokuqhelekileyo, i-stator ye-motor ye-asynchronous motor ineesethi ezimbini eziphambili kunye ne-axiliary windings, kwaye ii-ax zazo zihlala zihluke nge-90 ° kwindawo.I-winging encedisayo ixhunywe kwigridi yamandla ngokuhambelana neyona nto iphambili emva kokuba i-capacitor efanelekileyo ixhunyiwe kwichungechunge.Ngenxa yesiphumo sokwahlulwa kwesigaba samacandelo anje nge-capacitors, umjelo wokujika-jika okungundoqo kunye no-winding oncedisayo uyahluka nge-engile yesigaba ngexesha, kunye ne-pulse vibration yemagnethi enokubakho eveliswa yi-mawinging engundoqo kunye ne-winging encedisayo ngokulandelelana inokudityaniswa amandla ajikelezayo amagnetic, kwaye i-current induced in the rotor isekiwe.Umhlaba wemagnethi uyanyanzelwa, kwaye iindawo ezimbini zemagnethi ziyanxibelelana ukuvelisa itorque yokutsala yenjini.Uhlalutyo lwethiyori lungqina ukuba i-elliptical synthetic ejikelezayo yemagnethi yenqanaba elinye lemoto inokuboliswa ibe yizibuthe ezijikelezayo ezimbini ezijikelezayo zolandelelwano olulungileyo kunye nolandelelwano olubi.Isenzo, ukwenzela ukuba ubukhulu be-torque yokudonsa buchaphazeleke kakhulu.
Xa ukusasazwa kwendawo yomoya oyintloko kunye nokuncedisa kunye nokwahlukana kwesigaba sexesha lokuhamba kwangoku zombini i-angle yombane ye-90 degrees, i-ellipticity ye-synthetic field magnetic incinci;ukuba ubukhulu besakhono semagnethi engundoqo kunye ne-windings encedisayo iyafana, imeko ye-ellipticity encinci ye-synthetic field magnetic iguqulwa ibe yimo ejikelezayo Ukujikeleza i-magnetic field, oko kukuthi, i-motor kuphela inamandla omagnetic we-positive. ujikelezo, icandelo elingalunganga lolandelelwano nguziro, kwaye isalathiso sokwenziwa komsebenzi sikwangowona ulungileyo.Ngenxa yokuba iinxalenye zesigaba sokwahlula-hlula ezifana ne-capacitors zifikelela kumanqanaba ahlukeneyo e-offset yesigaba sangoku kwizantya ezahlukeneyo, akukho budlelwane bupheleleyo phakathi komthwalo okhoyo kunye nomthwalo wangoku we-motor yesigaba esinye.Eminye imisinga yomthwalo mikhulu kunemisinga yokungathwali mthwalo, kwaye eminye imisinga yomthwalo iya kuba nkulu kunomthwalo wangoku.
