Kukho izizathu ezibini eziphambili:
1. Ubukhulu becala ukusuka kwinqanaba le-rotor: xa i-motor induction ikwimo emisiweyo, ukusuka kwindawo yokujonga i-electromagnetic, kanye njenge-transformer, i-stator winding ye-motor eqhagamshelwe kwicala lonikezelo lombane ilingana ne-primary winding ye-motor. i-transformer, kunye ne-rotor winding kwi-circuit evaliweyo ilingana ne-second winding ye-transformer ejikelezayo emfutshane.Akukho uxhumano lombane phakathi kwe-stator winding kunye ne-rotor winding, kodwa kuphela uxhumano lwamagnetic.I-Magnetic flux yenza i-loop evaliweyo nge-stator, i-gap yomoya kunye ne-rotor core.Xa i-rotor ivuliwe ngenxa ye-inertia, intsimi yamagnetic ejikelezayo inqumla i-rotor winding kwisantya esiphezulu sokusika (isantya se-synchronous), ebangela ukuba i-rotor winding ibangele amandla aphezulu e-electromotive.Ke ngoko, umsinga omkhulu uqukuqela kwi-rotor conductor, eyenza amandla kazibuthe ukuphelisa i-stator magnetic field, njengokuba i-second magnetic flux ye-transformer iya kunciphisa i-flux yokuqala yamagnetic.
Ukuze kugcinwe i-original magnetic flux efanelekileyo kwi-voltage yonikezelo lwamandla ngelo xesha, i-stator iyakwandisa ngoku.Ngeli xesha, i-rotor yangoku inkulu kakhulu, ngoko ke i-stator yangoku iphinda inyuke kakhulu, ide iye kuthi ga kwi-4 ~ 7 amaxesha ombane olinganisiweyo, oko kuyisizathu sokuqala kwangoku.
Njengoko isantya semoto sinyuka, isantya apho i-stator magnetic field inqumla i-rotor conductor iyancipha, i-electromotive force induced in the rotor conductor iyancipha, kwaye yangoku kwi-rotor conductor nayo iyancipha.Ngoko ke, inxalenye ye-stator yangoku esetyenziselwa ukuchasana nempembelelo ye-magnetic flux eyenziwa yi-rotor yangoku iyancipha, ngoko ke i-stator yangoku iguquka ukusuka kwinkulu ukuya encinci kude kube yinto eqhelekileyo.
2. Ngokukodwa kwi-stator aspect: Ngokomthetho ka-Ohm, xa i-voltages ilingana, ixabiso elincinci le-impedance, likhulu ngoku.Ngethuba lokuqalisa kweemoto, i-impedance kwi-loop yangoku kuphela ukuchasana kwe-stator winding, eyenziwa ngokubanzi nge-copper conductor, ngoko ixabiso lokumelana lincinci kakhulu, ngaphandle koko i-current iya kuba nkulu kakhulu.
Ngethuba lenkqubo yokuqala, ngenxa yempembelelo ye-magnetic induction, ixabiso lokuphendula kwi-loop liyenyuka ngokuthe ngcembe, ukwenzela ukuba ixabiso langoku liyancipha ngokwemvelo lide libe lizinzile.
