Amandla e-electromotive angemuva akhiqizwa ngokuphikisana nokuthambekela kwamandla wamanje ekuguqukeni kokuphenduka. Amandla e-electromotive angemuva akhiqizwa kulezi zimo ezilandelayo: (1) lapho umsinga oshintshanayo udlula ikhoyili; (2) lapho i-conductor ifakwa endaweni eshintshanayo kazibuthe; (3) lapho ikhondukta inqamula insimu kazibuthe. Lapho izinto zikagesi ezinjengamakhoyili adluliswayo, amavalvu kagesi, amakhoyili okuxhumana, nama-motor windings esebenza, konke kukhiqiza amandla e-electromotive.
Ukwenziwa komshini ozinzile kudinga izimo ezimbili ezidingekayo: okokuqala, iluphu ye-conductive evaliwe. Okwesibili, amandla e-electromotive angemuva. Singaqonda ukwenzeka kwamandla e-electromotive abangelwa amandla avela ku-induction motor: ama-voltages e-symmetrical ezigaba ezintathu asetshenziswa kuma-winding stator we-motor umehluko wama-degree angu-120, okukhiqiza insimu yamagnetic ejikelezayo ejikelezayo, ukuze imigoqo ye-rotor ibekwe kulokhu. inkambu kazibuthe ejikelezayo ingaphansi kwamandla kazibuthe kagesi, ishintsha isuka ekunyakazeni emile iye kokujikelezayo, ikhiqize amandla alingelwe kumabha, kanye nokugeleza kwamanje okudalwe ku-loop evaliwe yamabha axhunywe amasongo okugcina e-conductive. Ngale ndlela, amandla kagesi noma amandla e-electromotive akhiqizwa kuma-rotor bars, futhi la mandla e-electromotive abizwa ngokuthi amandla e-electromotive back. Emotweni ye-rotor yesilonda, i-rotor open circuit voltage ingamandla ajwayelekile e-electromotive back.
Izinhlobo ezahlukene zezinjini zinezinguquko ezihluke ngokuphelele kusayizi wamandla e-electromotive angemuva. Usayizi wamandla we-electromotive angemuva we-asynchronous motor uyashintsha ngosayizi womthwalo nganoma yisiphi isikhathi, okuholela ezinkomba ezihluke kakhulu ezisebenza kahle ngaphansi kwezimo ezihlukene zomthwalo; kumotho kazibuthe unomphela, inqobo nje uma ijubane lihlala lingashintshile, ubukhulu bamandla e-electromotive angemuva abushintshile, ngakho-ke izinkomba zokusebenza kahle ngaphansi kwezimo ezihlukene zomthwalo zihlala zingashintshile.
Incazelo engokoqobo yamandla e-electromotive angemuva amandla e-electromotive aphikisana nokudlula kwamandla amanje noma ukuguqulwa kwamandla. Ebudlelwaneni bokuguqulwa kwamandla kagesi UIt=ε逆It+I2Rt, i-UIt ingamandla kagesi okufakwayo, njengamandla kagesi okufakwayo ebhethrini, injini noma i-transformer; I-I2Rt amandla okulahlekelwa ukushisa kumjikelezo ngamunye, okuwuhlobo lwamandla okulahlekelwa ukushisa, okuncane kuba ngcono; umehluko phakathi kokufakwayo kwamandla kagesi kanye nokulahlekelwa ukushisa kwamandla kagesi kuyingxenye yamandla awusizo ε逆Ihambisana namandla e-electromotive angemuva. Ngamanye amazwi, amandla e-electromotive angemuva asetshenziselwa ukukhiqiza amandla awusizo futhi ahlotshaniswa ngokuphambene nokulahlekelwa ukushisa. Uma amandla okulahlekelwa ukushisa aba makhulu, aba mancane amandla awusizo angafinyeleleka.
Uma sikhuluma ngokunenhloso, i-EMF yangemuva idla amandla kagesi kusekethe, kodwa akuyona "ukulahlekelwa". Ingxenye yamandla kagesi ehambisana ne-EMF engemuva izoguqulwa ibe amandla awusizo ezisetshenziswa zikagesi, njengamandla emishini enjini kanye namandla amakhemikhali ebhethri.
Kungabonakala ukuthi usayizi we-EMF engemuva usho amandla ekhono lezinto zikagesi zokuguqula ingqikithi yamandla okufakwayo abe amandla awusizo, okubonisa izinga lekhono lokuguqula impahla kagesi.
Izinto ezinquma i-EMF yangemuva Ngemikhiqizo yezimoto, inani lokujika kwe-stator, isivinini se-rotor angular, indawo kazibuthe ekhiqizwa uzibuthe we-rotor, kanye negebe lomoya phakathi kwe-stator ne-rotor yizici ezinquma i-EMF yangemuva ye-motor. . Lapho i-motor iklanyelwe, insimu kazibuthe ye-rotor kanye nenani lokuphenduka kwe-stator mawinding kunqunywa. Ngakho-ke, okuwukuphela kwesici esinquma i-EMF yangemuva yi-rotor angular velocity, noma isivinini se-rotor. Njengoba isivinini se-rotor sanda, i-EMF yangemuva nayo iyanda. Umehluko phakathi kobubanzi obungaphakathi be-stator kanye nobubanzi be-rotor obungaphandle kuzothinta usayizi wokuguquguquka kazibuthe okumazombezombe, okuzophinde kuthinte i-EMF yangemuva.
Izinto okufanele uziqaphele lapho injini isebenza ● Uma injini iyeka ukujikeleza ngenxa yokumelana nomshini ngokweqile, awekho amandla e-electromotive angemuva ngalesi sikhathi. Ikhoyili enokumelana okuncane kakhulu ixhunywe ngokuqondile emaphethelweni amabili okunikezwa kwamandla. Umsinga uzoba mkhulu kakhulu, ongashisa kalula injini. Lesi simo sizobhekana nokuhlolwa kwemoto. Isibonelo, ukuhlolwa kwetafula kudinga ukuthi i-motor rotor ibe sesimweni esimile. Ngalesi sikhathi, injini inkulu kakhulu futhi kulula ukuyishisa injini. Njengamanje, abakhiqizi abaningi bezimoto basebenzisa iqoqo lenani elisheshayo ekuhlolweni kwesitolo, okugwema ngokuyisisekelo inkinga yokushiswa kwezimoto okubangelwa isikhathi eside sokuhlala. Kodwa-ke, njengoba injini ngayinye ithintwa izinto ezahlukahlukene njengokuhlangana, amanani aqoqiwe ahluke kakhulu futhi awakwazi ukukhombisa ngokunembile isimo sokuqala semoto.
● Uma amandla kagesi axhunywe enjinini ephansi kakhulu kunevoltheji evamile, ikhoyili yenjini ngeke ijikeleze, awekho amandla e-electromotive angemuva azokhiqizwa, futhi injini izosha kalula. Le nkinga ivame ukwenzeka kumamotho asetshenziswa emigqeni yesikhashana. Isibonelo, izintambo zesikhashana zisebenzisa izintambo zikagesi. Ngenxa yokuthi zisetshenziswa kanye kanye nokuvimbela ukweba, iningi lazo lizosebenzisa izintambo eziwumgogodla we-aluminium ukulawula izindleko. Ngale ndlela, ukwehla kwamandla kagesi kulayini kuzoba kukhulu kakhulu, okuzoholela ekungeneni kwe-voltage enganele yenjini. Ngokwemvelo, amandla e-electromotive angemuva kufanele abe mancane. Ezimweni ezimbi kakhulu, injini kuzoba nzima ukuqala noma ngisho nokungakwazi ukuyiqala. Ngisho noma injini iqala, izosebenza ngamandla amakhulu esimweni esingavamile, ngakho-ke injini izoshiswa kalula.
