Uthotho lwe-YBK3 olunoqhushumbo olunamanqanaba amathathu enjini ye-asynchronous yomgodi wamalahle ongaphantsi komhlaba ingena umoya nge-axially, ivalwe ngokupheleleyo, ipholiswe ngefeni, i-squirrel-cage explosion-proof yesigaba sesithathu se-asynchronous motor, oluluthotho olusisiseko lweemotor ezinobungqina bokudubula ezenzelwe ukubuyisela indawo. Uluhlu lwe-YBK2 e-China, kunye nezibonelelo zokusebenza okuphezulu, i-torque ephezulu, umthamo onamandla ogqithisiweyo, ingxolo ephantsi, ephantsi. ukungcangcazela, umda omkhulu wokunyuka kobushushu, ukusebenza kakuhle, ukufakela okulula kunye nokugcinwa, kunye nobomi benkonzo ende. Ineengenelo zesakhiwo esinengqiqo-ubungqina bokudubula, ukusetyenziswa okukhuselekileyo nokuthembekileyo, kunye nenkangeleko entle. Inqanaba lobugcisa bemveliso lifikelele kwinqanaba eliphezulu lasekhaya.
