Ngenxa yokuqhubeka nokufuna ukusebenza kakuhle kweemoto, iirotor ezivaliweyo ziyaqatshelwa kancinci kancinci ngabavelisi beemoto.imoto engenaxesha linye enamanqanaba amathathu, ukulahleka kokungcangcazela kwepulse kwenzeka xa kujikeleziswa ngenxa yokubakho kweendawo zokutsala amazinyo ze-stator kunye ne-rotor. Ukuba i-rotor isebenzisa indawo evaliweyo, indawo yomoya esebenzayo iyafinyezwa, kwaye i-pulsation ye-magnetic field ye-air gap iyabuthathaka, ukuze kuncitshiswe amandla e-magnetic okuvuselela kunye nokunciphisa ukulahleka kwe-harmonic magnetic field, eluncedo ekuphuculeni ukusebenza kwe-motor.
Icala le-archImoto yokungenisa yesigaba esi-3yiparameter ebalulekileyo yerotor evaliweyo. Xa uhlobo lwerotor groove lufana, ukukhethwa kobude obuhlukeneyo be-arch kuya kuba nefuthe elahlukileyo ekusebenzeni kwemoto. Kunzima ukujonga ukufana kwerotor evaliweyo kuba akukho notch, kwaye kulula ukuba nengxaki efihliweyo kunye nokwandisa izinto ezingalawulekiyo.
Ukusetyenziswa kwe-rotor closed slot akunakunciphisa kuphela ukulahleka okulahlekileyo kunye nokulahleka kwesinyithi kwemoto, kodwa kukwanyusa i-rotor leakage reactance, nto leyo ekhokelela ekunciphiseni amandla, ukwanda komthwalo we-stator kunye nokwanda kokulahleka kwe-stator. Ukuqala kwe-torque kunye nokuqala kombane kwehla, izinga lokutyibilika liyanyuka. Ke ngoko, xa usebenzisa i-closed slot, utshintsho lwedatha yokusebenza kufuneka luqwalaselwe ngaxeshanye, ukuze ukusebenza kwemoto iyonke kube ngcono.
Imoto yokungenisaibhekisa kuhlobo lwemoto exhomekeke kwi-electromagnetic induction phakathi kweerotor ukuze ibangele umbane kwirotor ukuze kufezekiswe ukuguqulwa kwamandla e-electro mechanical. I-stator yemoto yokungenisa inamacandelo amathathu: i-stator core, i-stator winding kunye nesakhelo. I-rotor ine-rotor core, i-rotor winding kunye ne-rotary shaft. I-rotor core ikwayinxalenye yesekethe ephambili yemagnethi, ngokubanzi yenziwe ngamaphepha esinyithi e-silicon angama-0.5mm ubukhulu, i-core ixhomekeke kwi-rotary shaft okanye inkxaso ye-rotor. Ingaphandle le-rotor iyonke liyi-cylindrical.
Ii-Rotor windings zahlulwe zibe ziintlobo ezimbini: uhlobo lwekheyiji kunye nohlobo lwenxeba. Kwiimeko eziqhelekileyo, isantya se-rotor se-induction motor sihlala siphantsi kancinci okanye siphezulu kancinci kunesantya se-magnetic field ejikelezayo (isantya esihambelanayo), ngoko ke i-induction motor ikwabizwa ngokuba yi-"asynchronous motor". Xa umthwalo we-induction motor utshintsha, isantya kunye nesantya sokutyibilika kwe-rotor ziya kutshintsha ngokufanelekileyo, ukuze amandla e-electromotive, i-current kunye ne-electromagnetic torque kwi-rotor conductor zitshintshe ngokufanayo ukuhlangabezana neemfuno zomthwalo. Ngokwesantya sokutyibilika esihle nesingalunganga kunye nobukhulu, i-induction motor ineemeko ezintathu zokusebenza: i-motor, i-generator kunye ne-electromagnetic brake.
