Amandla kagesi, inkambu kazibuthe namandla Okokuqala, ukuze kube lula izincazelo ezilandelayo zezimiso zemoto, ake sibuyekeze imithetho/imithetho eyisisekelo mayelana namaza, amandla kazibuthe, namandla.Nakuba kukhona umuzwa wokulangazelela, kulula ukukhohlwa lolu lwazi uma ungazisebenzisi njalo izingxenye kazibuthe. Incazelo enemininingwane yomgomo wokuzungezisa Isimiso sokujikeleza kwemoto sichazwe ngezansi.Sihlanganisa izithombe namafomula ukuze sibonise. Uma uhlaka oluholayo luwunxande, amandla asebenza okwamanje ayacatshangelwa. Amandla F asebenza ezingxenyeni u-a no-c athi:
Ikhiqiza i-torque ezungeze i-axis emaphakathi. Isibonelo, uma kucutshungulwa isimo lapho i-engeli yokuzungezisa ingu-θ kuphela, amandla asebenza kuma-engeli angakwesokudla ku-b no-d athi sinθ, ngakho itorque engu-Ta yengxenye a iboniswa ngefomula elandelayo:
Uma kucatshangelwa ingxenye c ngendlela efanayo, itorque iphindwe kabili futhi ikhiqiza itorque ebalwa ngokuthi:
Njengoba indawo yonxande ingu-S=h·l, ukuyifaka esikhundleni sefomula engenhla kuveza imiphumela elandelayo:
Le fomula ayisebenzi nje onxande kuphela, kodwa nakwabanye umumo ojwayelekile njengemibuthano.Izimoto zisebenzisa lesi simiso. Okuthathwayo okubalulekile: Umgomo wokuzungezisa imoto ulandela imithetho (imithetho) ehlobene nemisinga, izinkundla kazibuthe namandla. Umgomo wokukhiqiza amandla wenjini Umgomo wokukhiqiza amandla wenjini uzochazwa ngezansi. Njengoba kushiwo ngenhla, i-motor iyisisetshenziswa esiguqula amandla kagesi sibe amandla, futhi ingafinyelela ukunyakaza okujikelezayo ngokusebenzisa amandla adalwe ngokusebenzisana kwenkundla kazibuthe kanye namandla kagesi. Eqinisweni, ngokuphambene, injini ingaphinda iguqule amandla emishini (ukunyakaza) ibe amandla kagesi ngokusebenzisa i-electromagnetic induction. Ngamanye amazwi,injiniinomsebenzi wokukhiqiza ugesi. Uma ucabanga ngokuphehla ugesi, cishe ucabanga ngamajeneretha (owaziwa nangokuthi “iDynamo”, “Alternator”, “Generator”, “Alternator”, njll.), kodwa isimiso siyefana nesamamotho kagesi, kanye ne isakhiwo esiyisisekelo siyefana. Ngamafuphi, i-motor ingathola ukunyakaza okujikelezayo ngokudlula okwamanje ngokusebenzisa izikhonkwane, ngokuphambene, lapho umshini wemoto ujikeleza, ukugeleza kwamanje phakathi kwezikhonkwane. Umsebenzi wokukhiqiza amandla wenjini Njengoba kushiwo ngaphambili, ukukhiqizwa kwamandla kwemishini kagesi kuncike ekungenweni kwe-electromagnetic.Ngezansi kunomfanekiso wemithetho efanele (imithetho) kanye neqhaza lokuphehla ugesi. Umdwebo ongakwesokunxele ubonisa ukuthi okwamanje kugeleza ngokomthetho kaFleming ongakwesokudla.Ngokuhamba kocingo ku-flux kazibuthe, amandla e-electromotive akhiqizwa ocingweni kanye nokugeleza kwamanje. Umdwebo ophakathi nendawo kanye nomdwebo ongakwesokudla ubonisa ukuthi ngokomthetho ka-Faraday kanye nomthetho we-Lenz, i-current igeleza ngezindlela ezihlukene lapho i-magnet (flux) isondela eduze noma kude nekhoyili. Sizochaza umgomo wokuphehlwa kukagesi ngalesi sisekelo. Incazelo enemininingwane yomgomo wokuphehla ugesi Ake sithi ikhoyili yendawo S (=l×h) izungeza ngesivinini esingama-angular sika-ω endaweni efanayo kazibuthe. Ngalesi sikhathi, kucatshangwa ukuthi isiqondiso esihambisanayo sendawo yekhoyili (umugqa ophuzi emfanekisweni ophakathi) kanye nomugqa oqondile (umugqa wamachashazi amnyama) ngokuphathelene nesiqondiso sokuminyana kazibuthe kwakha i-engeli engu-θ (=ωt), i-flux kazibuthe Φ ukungena kukhoyili kunikezwa yifomula elandelayo i-express:
Ngaphezu kwalokho, amandla e-electromotive eyengelwe u-E akhiqizwa ikhoyili ngokufakwa kwe-electromagnetic ami kanje:
Lapho isiqondiso esihambisanayo sendawo yekhoyili sincike ngakumagnetic flux, amandla e-electromotive aba uziro, futhi inani eliphelele lamandla e-electromotive likhulu kakhulu uma livundlile.
