Ukuba uye wafumana ithuba lokuthatha inxaxheba kuvavanyo lweemoto, unokuba nokuqonda okunzulu kwetekhnoloji yokuguqulwa kwamaza. Ngokukodwa abo baye bafumana izixhobo zovavanyo zakudala banokuziva ngcono itekhnoloji yokuguqulwa kwamaza.
Nokuba luvavanyo lokuhlola iimoto okanye uvavanyo lohlobo, inkqubo yokuqalisa imoto iya kuba namava. Ngokukodwa kwimeko yamandla amakhulu emoto kunye nomthamo wegridi encinci, ukuqala kwemoto akukho mthwalo kuya kuba nzima kakhulu. Inkqubo yovavanyo ifana nale, kwaye inkqubo yokubeka i-motor ekusebenzeni nayo inokucingelwa.
Uvavanyo lwestall kukuqinisekisa ukuba i-motor rotor ikwimo emileyo. Luvavanyo lweempawu zokuqalisa iimoto kunye neempawu zokugcwala. Kwiimotor frequency kwimizi-mveliso, ukuqala kuhlala kuyinto ebaluleke kakhulu, ngakumbi kwezinye iimeko ezikhethekileyo. Ngenxa yeemeko ezinje ngeemeko zokusebenza okanye imiqobo yokusebenza kwezixhobo, kuhlala kukho unikezelo lwamandla amatyeli emveliso kuphela, kwaye ngokuqinisekileyo iimotor frequency zefektri ziya kukhethwa.
Iifektri ezininzi zeemoto, ngakumbi ezo zisanda kuthenga okanye ziphucule izixhobo zovavanyo, zikwamkele umbane oguquguqukayo, ozisombulule ngokupheleleyo ingxaki yokuqalisa iimoto. Nangona kunjalo, kukho ukungonakali, oko kukuthi, ubuthathaka bokusebenza kwemoto abunakufunyanwa ngokupheleleyo. Kwakha kwakho ibhetshi yeenjini ezinesantya ezibini ezingakhange zifumane nakuphi na ukungahambi kakuhle ngexesha lovavanyo lomenzi, kodwa umsebenzisi wasilela ukuqalisa ngesantya esithile. Uphononongo olongezelelweyo lubonakalise ukuba i-motor yavavanywa kuphela ukuqala ukusebenza ngesantya esinye, kwaye ukusebenza kwemoto kwesinye isantya akuzange kufunyanwe kunganelanga. Nangona kunjalo, i-motor eneneni yaqalwa ngesantya esihambelanayo kunye nokusebenza kakubi kokuqala ngexesha lokusetyenziswa kokwenyani. Ngapha koko, kulula kakhulu ukuqalisa i-motor ngokuguquguquka okuguquguqukayo, yiyo loo nto inokuqalisa ngexesha lovavanyo kodwa inokuba neengxaki phantsi kweemeko zokusebenza kwamandla ombane.
Iinjini ezikumgangatho ophezulu ziyimveliso yesikhokelo somgaqo-nkqubo wesizwe. Iimfuno eziphezulu eziphezulu zoluhlu olusisiseko lweemoto zinyanzela abavelisi abahlukeneyo ukuba benze uphuculo loyilo ngeendlela zobugcisa, ngokuqinisekileyo zinokubandakanya utyalo-mali olwandisiweyo.
Xa i-motor frequency motor iqalwa kwi-voltage egcweleyo, ngenxa yemfuno yokuqala ye-torque ye-motor, ukuqala kwangoku kumaxesha angama-5-7 angoku, okuchitha umbane kwaye kubangela umonakalo omkhulu kwigridi yamandla. Ukuba i-frequency eguquguqukayo iqala yamkelwa, impembelelo yokuqalisa ngoku kwigridi yamandla iyancitshiswa, amatyala ombane agcinwa, kwaye impembelelo ye-inertia yokuqala kwisantya se-inertia enkulu yezixhobo iyancitshiswa, eyandisa ubomi benkonzo. kwezixhobo. Iluncedo kwigridi yamandla, i-motor kunye nezixhobo ezitsalwayo. Ifuthe letekhnoloji eguquguqukayo yetekhnoloji ekuqaliseni kweemoto zicace gca, kodwa kukwakho nezinye izinto ezingathandekiyo ekusetyenzisweni kwee-motor frequency frequency. Ngokomzekelo, amaza angenayo i-sinusoidal eyenziwa yi-inverter anempembelelo enkulu ekuthembekeni kwe-motor kwaye iyakwazi ukuvelisa i-shaft currents. Ngokukodwa kwiimoto ezinamandla amakhulu kunye nombane olinganisiweyo ophezulu, ingxaki imbi kakhulu. Ukuze ugweme ingxaki yangoku ye-shaft, ukukhethwa kwezinto ezithintekayo zeemoto kunye nemilinganiselo yokukhusela i-shaft yangoku iyimfuneko kakhulu.
