Njengoko i-motor current inyuka, ngaba i-torque nayo iya kwanda?

I-torque sisalathiso esibalulekileyo sokusebenza kweemveliso zemoto, ebonisa ngokuthe ngqo amandla emoto ukuqhuba umthwalo.Kwiimveliso zemoto, i-torque yokuqala, i-torque elinganiselweyo kunye ne-torque ephezulu ibonisa amandla emoto kumazwe ahlukeneyo.Iitorque ezahlukeneyo zihambelana Kukho kwakhona umahluko omkhulu kubukhulu bangoku, kunye nobudlelwane phakathi kobukhulu bangoku kunye ne-torque bukwahluke phantsi kokungabikho komthwalo kunye nomthwalo we-motor.

Itorque eveliswa yimotor ngeli xesha xa i-voltage ifakwa kwimotor kwindawo yokumisa ibizwa ngokuba yi-torque yokuqala.Ubungakanani be-torque yokuqala buhambelana nesikwere se-voltage, ukwanda kunye nokunyuka kokumelana ne-rotor, kwaye kuhambelana nokusabela kokuvuza kwemoto.Ngokuqhelekileyo, phantsi kwemeko ye-voltage epheleleyo, i-torque yokuqala ye-AC ye-asynchronous motor ingaphezulu kwe-1.25 yamaxesha e-torque elinganisiweyo, kwaye i-current ehambelanayo ibizwa ngokuba yi-start current, edla ngokumalunga ne-5 ukuya kwi-7 yangoku yangoku.

I-motor phantsi kwemeko yokusebenza elinganisiweyo ihambelana ne-torque elinganisiweyo kunye nokulinganiswa kwangoku kwemoto, eziziiparameters eziphambili phantsi kweemeko eziqhelekileyo zokusebenza kwemoto;xa i-motor igcwele kakhulu ngexesha lokusebenza, ibandakanya i-torque ephezulu ye-motor, ebonisa ukuchasana kwe-motor Umthamo wokulayisha ngaphezulu uya kuhambelana nombane omkhulu phantsi kwemeko ye-torque ephezulu.

Kwimoto egqityiweyo, ubudlelwane phakathi kwetorque ye-electromagnetic ye-asynchronous motor kunye ne-magnetic flux kunye ne-rotor yangoku iboniswe kwifomula (1):

Itorque ye-electromagnetic = engaguqukiyo × imagnethi eguquguqukayo × icandelo elisebenzayo lesigaba ngasinye sangoku serotha… (1)

Inokubonwa kwifomula (1) ukuba i-torque ye-electromagnetic ihambelana ngokuthe ngqo nemveliso ye-gap flux yomoya kunye necandelo elisebenzayo le-rotor yangoku.I-rotor yangoku kunye ne-stator yangoku ilandela ngokusisiseko ubudlelwane obuguquguqukayo obuguquguqukayo, oko kukuthi, xa i-flux yamagnetic ingafikeleli kwi-saturation, i-torque ye-electromagnetic kunye neyangoku zihambelana ngokufanelekileyo.I-torque ephezulu lixabiso eliphezulu le-motor torque.

Eyona torque ye-electromagnetic ibaluleke kakhulu kwimoto.Xa i-motor isebenza, ukuba umthwalo unyuka ngokukhawuleza ixesha elifutshane kwaye ubuyele kumthwalo oqhelekileyo, ukuba nje i-torque yokuqhomfa iyonke ayikho mkhulu kunowona mthamo we-electromagnetic uphezulu, i-motor isenokuthi iqhube ngokuzinzileyo;kungenjalo, injini iya kuma.Kuyabonakala ukuba okukhona ubuninzi betorque ye-electromagnetic, kokukhona komelele umthamo wexesha elifutshane wokulayisha ngaphezulu kwemoto, ngoko ke amandla omthwalo ogqithisiweyo wemoto abonakaliswa ngumlinganiselo wetorque enkulu ye-electromagnetic kwitorque elinganisiweyo.
