Injiniukugqithisela kubhekisa kwimeko apho amandla okusebenza emoto adlula amandla alinganisiweyo. Xa imoto igqithisile, iimpawu zezi zilandelayo: imoto ishushu kakhulu, isantya siyehla, kwaye isenokuma; imoto yenza isandi esingavakaliyo esihamba nokungcangcazela okuthile; ukuba umthwalo utshintsha kakhulu, isantya semoto sinokunyuka size sehle ngequbuliso.
Izizathu zokuxinana kweemoto ziquka ukulahleka kwesigaba, i-voltage yokusebenza edlula ixabiso elivumelekileyo le-voltage elinganisiweyo, kunye nokungaphumeleli koomatshini kwemoto okubangela ukwehla okukhulu kwesantya okanye ukuma, njl.
Ukusebenza ngokugqithisileyo kwemoto kuya kuyichaphazela kakhulu ubomi bemoto. Ukubonakaliswa ngokuthe ngqo kokugqithisileyo kukuba umsinga wemoto uyanda, nto leyo ebangela ukuba ii-motor windings zibe shushu kakhulu, kwaye i-winding insulation iyaguga kwaye ingaphumeleli ngenxa yomthwalo ogqithisileyo wobushushu.
Emva kokuba injini igcwele kakhulu, kunokugwetywa ngokwemeko yokwenyani yokujika. Ukubonakaliswa okucacileyo kukuba inxalenye yokugquma yokujika imnyama kwaye iyaphuka. Kwiimeko ezinzima, yonke inxalenye yokugquma iyaguqulwa ibe yi-carbon ibe yi-powder; kwaye umaleko wokugquma wentambo ye-electromagnetic ejikelezayo wonakele kakhulu. Xa iguga, ifilimu yepeyinti yentambo ye-enamel iba mnyama, kwaye kwiimeko ezinzima ixotyulwa ngokupheleleyo; ngelixa kwintambo ye-mica kunye nentambo ye-electromagnetic egqunywe yisilika, umaleko wokugquma wahlulwe kwi-conductor.
Iimpawu ze-overloaded motor windings ezahlukileyo kwi-phase loss, turn-to-turn, ground kunye ne-phase-to-phase zizinto ezidala kakhulu kwi-winding, kunokuba ziingxaki zomgangatho wendawo. Ngenxa ye-overloaded motor, kuya kubakho neengxaki zokufudumeza kwinkqubo ye-bearing. I-motor efumana i-overload failure iya kukhupha ivumba elibi lokutsha kwindawo engqongileyo, kwaye kwiimeko ezinzima inokuhamba nomsi omnyama omkhulu.
