Amandla e-electromotive angasemva aveliswa ngokuchasa ukuthambekela kwangoku ekujikeni ukuguquka. Amandla e-electromotive angasemva aveliswa kwezi meko zilandelayo: (1) xa i-alternating current idlula kwikhoyili; (2) xa i-conductor ibekwe kwindawo yemagnethi etshintshanayo; (3) xa i-conductor inqumla kwimagnethi. Xa izixhobo zombane ezinje ngeekhoyili zombane, iivalvu ze-electromagnetic, iikhoyili zonxibelelwano, kunye neemotor windings zisebenza, zonke zivelisa amandla e-electromotive.
Isizukulwana se-stay-state current sifuna iimeko ezimbini eziyimfuneko: okokuqala, i-loop conductive evaliweyo. Okwesibini, umva amandla e-electromotive. Sinokuyiqonda into eyenziwa ngamandla e-electromotive evela kwi-motor induction: i-voltage ye-symmetrical yesigaba sesithathu isetyenziswe kwi-stator windings ye-motor kunye nokwahlukana kwee-degrees ze-120, ivelisa i-circular ejikelezayo imagnethi, ukwenzela ukuba imivalo ye-rotor ibekwe kule ndawo. Umhlaba ojikelezayo wemagnethi uphantsi kwamandla e-electromagnetic, utshintsha ukusuka kwi-static ukuya kwintshukumo ejikelezayo, ukuvelisa amandla okwenziwa kwimivalo, kunye nokuhamba okukhoyo ngoku kujikelezo oluvaliweyo lwemivalo edityaniswe ngamakhonkco okugqibela okuqhuba. Ngale ndlela, amandla ombane okanye amandla e-electromotive aveliswa kwii-rotor bars, kwaye le mandla e-electromotive yinto ebizwa ngokuba yi-back electromotive force. Kwi-rotor motor yenxeba, i-voltage ye-rotor evulekileyo yesiphaluka yinto eqhelekileyo yamandla e-electromotive.
Iindidi ezahlukeneyo zeenjini zineenguqu ezihluke ngokupheleleyo kubungakanani bamandla ombane ongemva. Ubungakanani be-electromotive force yangasemva ye-asynchronous motor utshintsho kunye nobukhulu bomthwalo nangaliphi na ixesha, okukhokelela kwiimpawu ezisebenzayo ezahlukeneyo phantsi kweemeko ezahlukeneyo zomthwalo; kwimotor yemagnethi esisigxina, nje ukuba isantya sihlala singatshintshi, ubukhulu be-electromotive force yangasemva buhlala bungatshintshi, ngoko ke izikhombisi ezisebenzayo phantsi kweemeko ezahlukeneyo zomthwalo zihlala zingatshintshi.
Intsingiselo yomzimba yamandla e-electromotive angasemva yi-electromotive force echasene nokuhamba kwangoku okanye utshintsho lwangoku. Kubudlelwane boguqulo lwamandla ombane UIt=ε逆It+I2Rt, i-UIt ligalelo lamandla ombane, njengegalelo lamandla ombane kwibhetri, imoto okanye isitshintshi; I-I2Rt amandla okulahlekelwa bubushushu kwisekethe nganye, luhlobo lwamandla okulahleka kobushushu, encinci ngcono; Umahluko phakathi kwegalelo lamandla ombane kunye nelahleko yobushushu yamandla ombane yinxalenye yamandla aluncedo ε逆Ingqamana ne-electromotive force yangasemva. Ngamanye amazwi, amandla e-electromotive angasemva asetyenziselwa ukuvelisa amandla aluncedo kwaye ahambelana ngokungafaniyo nokulahleka kobushushu. Okukhona ukulahleka kwamandla obushushu, kokukhona kuncinci amandla aluncedo anokufumaneka.
Ukuthetha ngenjongo, i-EMF yangasemva idla amandla ombane kwisekethe, kodwa "ayiyolahleko". Inxalenye yamandla ombane ehambelana ne-EMF yangasemva iya kuguqulwa ibe ngamandla aluncedo kwisixhobo sombane, njengamandla omatshini wemoto kunye namandla ekhemikhali ebhetri.
Ingabonwa ukuba ubungakanani be-EMF yangasemva buthetha amandla okusebenza kwesixhobo sombane ukuguqula amandla egalelo lilonke abe ngamandla aluncedo, abonakalisa inqanaba lesakhono sokuguqula isixhobo sombane.
Izinto ezigqiba umva we-EMF Kwiimveliso zemoto, inani lokujika kwe-stator, i-rotor ye-angular velocity, i-magnetic field eveliswa yimagnethi ye-rotor, kunye nomsantsa womoya phakathi kwe-stator kunye ne-rotor zizinto ezimisela umva we-EMF yemoto. . Xa i-motor yenzelwe, i-rotor magnetic field kunye nenani lokujika kwe-stator winding lichongwa. Ngoko ke, into kuphela emisela i-EMF yangasemva yi-rotor ye-angular velocity, okanye isantya se-rotor. Njengoko isantya se-rotor sanda, i-EMF yangasemva iyanda. Umahluko phakathi kwe-stator yangaphakathi ye-diameter kunye ne-rotor yangaphandle ye-diameter iya kuchaphazela ubungakanani be-winding magnetic flux, eya kuchaphazela kwakhona i-EMF yangasemva.
Izinto ekufuneka ziqwalaselwe xa i-motor isebenza ● Ukuba i-motor iyeka ukujikeleza ngenxa yokumelana okugqithisileyo komatshini, akukho mandla e-electromotive angasemva ngeli xesha. Ikhoyili enokumelana okuncinci kakhulu idibaniswe ngokuthe ngqo kwiziphelo ezimbini zonikezelo lwamandla. Umsinga uya kuba mkhulu kakhulu, onokutshisa lula i-motor. Lo mbuso uya kudibana novavanyo lwemoto. Ngokomzekelo, uvavanyo lwe-stall lufuna ukuba i-motor rotor ibe kwimeko yokumisa. Ngeli xesha, i-motor inkulu kakhulu kwaye kulula ukuyitshisa i-motor. Okwangoku, uninzi lwabavelisi beemoto basebenzisa ukuqokelelwa kwexabiso kwangoko kuvavanyo lwe-stall, oluthintela ingxaki yokutsha kwemoto okubangelwa lixesha elide lokuhlala. Nangona kunjalo, kuba injini nganye ichatshazelwa zizinto ezahlukeneyo ezinje ngendibano, amaxabiso aqokelelweyo ahluke kakhulu kwaye akanakukwazi ukubonakalisa ngokuchanekileyo imeko yokuqala yemoto.
● Xa amandla ombane ombane aqhagamshelwe kwimotor esezantsi kakhulu kunombane oqhelekileyo, icoil yemoto ayiyi kujikeleza, akukho mandla ombane angemva aya kuveliswa, kwaye imotor iya kutshisa ngokulula. Le ngxaki idla ngokuvela kwiinjini ezisetyenziswa kwimigca yethutyana. Umzekelo, iintambo zethutyana zisebenzisa iintambo zombane. Ngenxa yokuba zisetyenziselwa ixesha elinye kunye nokuthintela ubusela, uninzi lwazo luya kusebenzisa iingcingo ezingundoqo ze-aluminiyam ukulawula iindleko. Ngale ndlela, ukuhla kwe-voltage kumgca kuya kuba kukhulu kakhulu, okukhokelela ekungeneni kwe-voltage eyaneleyo kwi-motor. Ngokwemvelo, amandla e-electromotive angasemva kufuneka abe mncinci. Kwiimeko ezinzima, injini iya kuba nzima ukuyiqalisa okanye ingakwazi ukuyiqala. Nokuba i-motor iqala, iya kubaleka kumbane omkhulu kwimeko engaqhelekanga, ngoko ke imoto iya kutshiswa ngokulula.
