I-YFB4 yochungechunge lwe-YFB4 luqhushumbo-ubungqina besigaba sesithathu se-asynchronous motor yi-self-fan-cooled squirrel-cage yesigaba sesithathu se-asynchronous motor. Uneempawu zobukhulu obuncinci, ubunzima bokukhanya, ukusebenza okuthembekileyo, ukubonakala okuhle, njl njl. Kwakhona kunokusebenza okuphezulu, ingxolo ephantsi, i-vibration encinci kunye nokunyuka kweqondo lokushisa eliphantsi. Ukusebenza okukhulu, okugqwesileyo, okuphambili kunye nokulungelelaniswa kobungqina bokudubula, ukusetyenziswa okukhuselekileyo nokuthembekileyo, njl.
Iinjini zokuthintela ukuqhuma kothuli zifaneleka ikakhulu iindawo apho uthuli olunokutsha lukhona kumayeza, amalaphu, isinyithi, ukulungiswa kweenkozo, ukusetyenzwa kwesondlo, izichumisi zekhemikhali, icuba, ukwenza iphepha, izinto zokwenziwa, izinto zokwakha, njl.
