Ama-motor avikela ukuqhuma asekhona iminyaka engaphezu kwekhulu futhi asetshenziswa ezimbonini ezahlukahlukene. Umlando wama-motor avikela ukuqhuma uyathakazelisa futhi kufanele ufundwe ngokucophelela.
Ngo-1879, injini yokuqala engaqhumi yaqalwa yi-Siemens. Le moto yenzelwe ukusetshenziswa ezimayini zamalahle futhi ihlolwe ezindaweni ezinokuqhuma okukhulu. Le moto yenzelwe ukuvimbela noma yikuphi ukusha kwegesi evuthayo, okungaba yingozi ezimayini zamalahle. Kusukela ngaleso sikhathi, izinjini ezingaqhumi ziye zasetshenziswa kabanzi ekukhiqizeni amakhemikhali, uwoyela negesi, izimayini kanye nezinye izimboni. Lezi zinjini zisiza ekwandiseni izinga lokuphepha kulezi zimboni, zivikela abasebenzi kanye nemishini ekuqhumeni okuyingozi.
Ama-motor angaqhumi aklanyelwe ukuvikela ezinhlansini nakweminye imithombo yokushisa ezindaweni eziyingozi. Lawa ma-motor angamelana namazinga okushisa aphezulu, ukucindezeleka okuphezulu kanye nezinye izimo ezimbi kakhulu. Avalwe futhi ukuze kuvinjelwe noma yiliphi igesi noma uthuli oluvuthayo ukuthi lungangeni enjinini bese kubangele ukuqhuma. Eminyakeni edlule, ubuchwepheshe be-motor obungaqhumi buye bashintsha baba phephile futhi buthembeke kakhudlwana. Intuthuko ezintweni zokwakha, izinqubo zokukhiqiza, kanye nobunjiniyela yenze imiklamo yaba ngcono futhi ephumelelayo. Namuhla, ama-motor angaqhumi ayizingxenye ezibalulekile ezinqubweni eziningi zezimboni kanye nezicelo.
Ekuphetheni, umlando wezinjini ezingaqhumi ungowokusungula izinto ezintsha, ukuphepha kanye nentuthuko. Kusukela ekusetshenzisweni kwezimayini zamalahle zakuqala kuya ekusetshenzisweni kabanzi kwanamuhla ezimbonini ezahlukahlukene, lezi zimoto zisiza ekuvikeleni abasebenzi kanye nemishini ekuqhumeni okuyingozi. Njengoba ubuchwepheshe buqhubeka nokuthuthuka, singalindela ukubona intuthuko eyengeziwe kubuchwepheshe bezinjini ezingaqhumi.
