Iimoto ezithintela ukuqhuma bezikho kangangeminyaka engaphezu kwekhulu kwaye zisetyenziswa kumashishini ahlukeneyo. Imbali yeemoto ezithintela ukuqhuma inomdla kwaye ifanelwe kuhlolisiswa ngokusondeleyo.
Ngo-1879, injini yokuqala engaqhumiyo yaqaliswa yiSiemens. Le moto yenzelwe ukusetyenziswa kwimigodi yamalahle kwaye ivavanyiwe kwiindawo ezinokuqhuma kakhulu. Le moto yenzelwe ukuthintela naluphi na uhlaselo ekuvutheni iigesi ezivuthayo, ezinokubulala kwimigodi yamalahle. Ukususela ngoko, iimoto ezingaqhumiyo ziye zasetyenziswa kakhulu kwimveliso yeekhemikhali, ioyile negesi, imigodi kunye neminye imimandla. Ezi moto zinceda ukonyusa umgangatho wokhuseleko kwezi mizi-mveliso, zikhusela abasebenzi kunye nezixhobo kwiiqhushumbo ezinobungozi.
Iimoto ezithintela ukuqhuma zenzelwe ukukhusela kwiintlantsi kunye neminye imithombo yokutsha kwiindawo ezinobungozi. Ezi moto zinokumelana nobushushu obuphezulu, uxinzelelo oluphezulu kunye nezinye iimeko eziqatha. Zikwavalwa ukuthintela nayiphi na igesi okanye uthuli olunokutsha ukuba lungangeni kwimoto kwaye lubangele ukuqhuma. Kwiminyaka edlulileyo, iteknoloji yeemoto ezithintela ukuqhuma iye yaguquka yaba yekhuselekileyo kwaye inokuthenjwa ngakumbi. Ukuqhubela phambili kwizixhobo, iinkqubo zokuvelisa, kunye nobunjineli kwenze uyilo lwaba lusebenza kakuhle kwaye lusebenza kakuhle. Namhlanje, iimoto ezithintela ukuqhuma zizinto ezibalulekileyo kwiinkqubo ezininzi zoshishino kunye nokusetyenziswa kwazo.
Ukuqukumbela, imbali yeemoto ezikwaziyo ukumelana nokuqhuma yimbali yezinto ezintsha, ukhuseleko kunye nenkqubela phambili. Ukususela kwizicelo zokuqala zemigodi yamalahle ukuya ekusetyenzisweni ngokubanzi kwanamhlanje kumashishini ahlukeneyo, ezi moto zinceda ekukhuseleni abasebenzi kunye nezixhobo kwiingozi zokuqhuma. Njengoko ubuchwepheshe buqhubeka buphuhla, sinokulindela ukubona inkqubela phambili ngakumbi kubuchwepheshe beemoto ezikwaziyo ukumelana nokuqhuma.
