Uma kuqhathaniswa nezincane futhiizinjini ezinosayizi omaphakathi,high-voltage motorskuyabiza, futhi izimo zohlelo lwazo zibucayi futhi zikhethekile. Kungakhathaliseki ukuthi ukulahlwa komzimba wemoto ngemva kwephutha noma ezinye izinkinga ezivela ephutheni, kungase kube kubi kakhulu kunalokho esingakucabanga. Ngalesi sizathu, amathuluzi okuvikela okuhlukanisayo asetshenziselwa izinjini ezinamandla kagesi asetshenziswa kwezinye izikhathi ezikhethekile, inhloso yazo okuwukuthola izinkinga ngesikhathi nangempumelelo futhi kuvinjwe ukuwohloka okwengeziwe kwezinkinga.
Ukuvikelwa okuhlukile kuyisinyathelo sokuvikela esisebenza kahle kakhulu sokusebenza okuphephile kwezinto zikagesi. Isebenzisa izici zokucupha izenzo zokuvikela ngomehluko we-vector phakathi kokufakwayo kwamanje kanye nokukhishwayo kwamanjeizinto zikagesi, ukwenza noma iyiphi inethiwekhi kagesi enezimbobo ezimbili, i-generator, motor, transformer kanye nezinye izinto zikagesi zinezinhlelo zokusebenza zakudala kakhulu.
Ukuvikela okuhlukile kusetshenziswa kakhulu kumamothoni amakhulu anamandla kagesi. Isibonelo, ama-motor-high-voltage asetshenziswa emandleni amakhulu emayini kanye nemishini yokungenisa umoya eyinhloko kufanele ifakwe imishini yokuvikela ehlukile ukuze kuqinisekiswe ukusebenza okuphephile nokuthembekile kohlelo futhi kugwenywe ukulahlekelwa okukhulu kwezomnotho kanye nezingozi zokuphepha ezibangelwa ukuvalwa okungalindelekile.
Ama-stator windings amamotho amakhulu anamandla kagesi ngokuvamile asebenzisa uxhumano lwenkanyezi, olunamatheminali amathathu okukhiphayo ngokuzenzekelayo. Lapho kwethulwa ukuvikela okuhlukile, injini kufanele ibe namatheminali ayi-6 okukhiphayo. Idivayisi yokuvikela ehlukile esetshenziswa kumotho isebenza ngale ndlela: thola imisinga yokuqala neyokuphela kwemoto, futhi uqhathanise umehluko wesigaba kanye ne-amplitude phakathi kwemisinga yokuqala neyokuphela. Ngaphansi kwezimo ezijwayelekile, umehluko we-amplitude kanye nesigaba phakathi kwemisinga yokuqala neyokuphela ingu-zero, okungukuthi, i-current egeleza ku-motor ilingana ne-current egeleza ephuma emotweni; lapho iphutha lesifunda esifushane njengesigaba-kuya-isigaba, ukujika-kujika noma ukuya phansi kwenzeka ngaphakathi kwenjini, umbane ohlukile ukhiqizwa phakathi kokubili futhi ufinyelele inani elithile, umsebenzi wokuvikela uyasebenza.
