Umgaqo osebenzayo wemoto yomgca ufana ncam naleyo yemoto ejikelezayo. Umzekelo, xa ujiko oluphambili lwemoto yokungeniswa komgca luqhagamshelwe kumthombo wamandla we-AC, intsimi yamagnetic ehambayo iveliswa kwisikhewu somoya. Lo mmandla wemagnethi uhambayo ubangela amandla e-electromotive kwi-winding yesibini, evelisa umsinga. Le yangoku isebenzisana nemagnethi kwi-gap yomoya, ivelisa i-electromagnetic thrust eqhubela okwesibini. Ukuba ujiko oluphambili luhlala lumile, ukujija okwesibini kuhamba ngomgca phantsi kokutyhala; ngenye indlela, ujiko oluphambili luhamba ngokulandelelana.
Ukongeza, itekhnoloji yokulawula idrayivu yemoto yomgca nayo ibalulekile. Inkqubo egqwesileyo yokusetyenziswa kwemoto yomgama ayifuni kuphela -ukusebenza okuphezulu kwemoto emgceni kodwa nenkqubo yolawulo enokwanelisa iimfuno zobugcisa nezoqoqosho ngelixa iqinisekisa ukhuseleko nokuthembeka.
