Iinjini ze-AC kunye ne-DC zezona ntlobo zixhaphakileyo zeemoto ezisetyenziswa kwiinkqubo ezahlukeneyo. Ukuqonda umahluko phakathi kwezi ntlobo zimbini zeenjini kubalulekile ekukhetheni imotor eyiyo kwisicelo esithile.
Imigangatho yovavanyo lwenqanaba lesithathu le-asynchronous motor amandla ovavanyo idlala indima ebalulekileyo ekukhuthazeni ukusetyenziswa kwamandla okuzinzileyo kunye nokunciphisa impembelelo yokusingqongileyo.
