Iningi lezinhlelo zokusebenza zezimoto zizohlonyiswa ngemishini yokubamba i-overload, okungukuthi, lapho i-motor current idlula inani elibekiwe ngenxa yokugcwala ngokweqile, umyalo wokubamba uzosetshenziswa ukuze kusetshenziswe ukuvikela.
Uma injini ibhajwe ngokomshini, noma kukhona amaphutha kagesi afana nomhlabathi, isigaba-to-isigaba, kanye nokujika-kujika, umyalo wokuvikela nawo uzosebenza ngempumelelo ngenxa yokwanda kwamandla. Kodwa-ke, uma okwamanje kungakhuphuki enanini lesilungiselelo sokuvikela, idivayisi yokuvikela ngeke isebenzise umyalo ohambisanayo.
Ikakhulukazi endabeni yamaphutha kagesi ekujikeni, ngenxa yezifunda ezihlukene zamaphutha, kuqala ukukhombisa ukungalingani kwamanje. Kwezinye izimo lapho iphutha lingelikhulu kakhulu, injini ingase iqhubeke nokusebenza esimweni sokungalingani kwamanje kuze kube yilapho kwenzeka inkinga enkulu; ngakho-ke, ngemva kokuba iphutha likagesi lenzeka ekujikeni kwe-motor, i-current izobe ingalingani emazingeni ahlukahlukene, futhi izinga lamanje lesigaba esithile lizokhula, kodwa ukwanda kuncike ezingeni lephutha, futhi kungase kungabangela ngempela injini. idivayisi yokuvikela; lapho iphutha liba noshintsho olukhulu lwekhwalithi, i-winding izoqhuma ngokushesha, futhi injini izoba sesimweni sokuphulwa kwesifunda, kodwa ukunikezwa kwamandla angeke kunqanyulwe.
Ngokulungiselelwa kwamanje kokuvikela ukugcwala ngokweqile, lapho ukulungiselelwa kukuncane kakhulu, kuzokwenziwa ukuvikelwa uma kunokugcwala okuncane, okuthinta ukusebenza okuvamile; uma ukulungiselelwa kukukhulu kakhulu, ngeke kudlale indima yokuvikela; amanye amadivaysi okuvikela awakwazi nje ukuthatha isinyathelo esimweni samanje esikhulu, kodwa futhi asebenzise ukuvikelwa kwezinkinga zokungalingani ngokweqile.
