YHiinjini zothotho zivalelwe ngokupheleleyo ifeni epholileyo isigaba sesithathu se-asynchronous induction motor yeelwandlesebenzisa.Iinjini zineempawu ezintle zengxolo ephantsi, ukungcangcazela okuncinci, itorque ephezulu etshixiweyo kunye nokusebenza okuthembekileyo.Zingasetyenziselwa ukuqhuba oomatshini abahlukeneyoiinqanawa, kubandakanywa iimpompo, ii-ventilators, i-separators, oomatshini be-hydraulic kunye nabanye oomatshini.Iinjini zinokusetyenziswa kwiindawo ezinobungozi ezinamathontsi ombethe, inkungu yetyuwa, inkungu yeoyile, ukungunda, ukungcangcazela kunye nokothuka.
