Ngobaizinjini zikagesi zesigaba ezintathu, ukugcinwa kwe-voltage elinganiselwe kubalulekile ekusebenzeni kahle. Ukuchezuka kule voltage eshiwo kungase kubangele uhla lwemiphumela eyingozi, ikakhulukazi uma i-voltage iphezulu kakhulu. Kulokhu, i-motor core izongena ku-saturation kazibuthe. Lesi simo senzeka lapho inkambu kazibuthe ngaphakathi komgogodla ifinyelela umthamo wayo omkhulu, okuyenza ingakwazi ukuguqula ngempumelelo amandla kagesi abe amandla emishini.
Njengoba iI-motor induction yezigaba ezintathuI-voltage iyanda, i-stator current nayo ikhula kakhulu. Lokhu kunyuka kwamanje kungabangela ukuthi ama-winding ashise kakhulu. Ukushisa okudlulele okukhiqiziwe kungalimaza ukuvala ama-windings, okuholela ezinkingeni zekhwalithi ezingaba khona njengokutubeka okumazombezombe. Lokhu ngeke nje kufinyeze impilo yemoto, kungaholela nasekulungiseni okubizayo noma ukushintshwa.
Ukwengeza, lapho injini isebenza ngaphandle kwe-voltage yayo elinganiselwe, ingase ingasebenzi kahle. Ukusebenza kahle kwezimoto kuncipha, okuholela ekunciphiseni kwetorque namandla okukhipha amandla. Lokhu kungasebenzi kahle kungabangela ukuthi injini idonse amandla amanje ukuze igcine ukusebenza, kuqhubekisele phambili inkinga yokushisa. Ezimweni ezimbi kakhulu, injini ingase ime noma yehluleke ngokuphelele, okuholela ekuphelelweni kwesikhathi okungahleliwe nokulahlekelwa ukukhiqiza.
Kafushane, ukusebenza a3 isigaba sokungeniswa motorkuma-voltage aphambuke ezincazelweni ezilinganiselwe kungaba nemiphumela emibi kakhulu. Ubungozi bokugcwala kukazibuthe, ukwanda kwe-stator current kanye nokushisa okulandelanayo kokumazombezombe kungaholela ezinkingeni ezingathi sína zekhwalithi, okuhlanganisa ukutubeka okumazombezombe. Ukuqinisekisa impilo ende nokusebenza kahle kwemoto, i-voltage kumele iqashwe futhi igcinwe ngaphakathi kwemikhawulo ethile. Ngokwenza lokhu, opharetha bangagwema ukulungiswa okubizayo futhi baqinisekise ukusebenza okuthembekile kwezimoto.
