Ukuqhuba okuguquguqukayosisixhobo se-Ac motor drive.Nge-topology ekhethekileyo, isantya sokulawula kunye ne-torque ngokutshintsha rhoqo ukunikezelwa kwamandla okufakwayo.Iya kulawula i-motor ukuqala kakuhle kakhulu.Vsdingasetyenziswa kwisicelo ukusuka kwifeni encinci, usetyenziso lwempompo ukuya kwicompressor enkulu, ukuhambisa njalo njalo.
I-variable frequency drive isetyenziswa kwi-drive system ebandakanya i-Ac motor, isilawuli se-drive kwaye isebenze i-interface.Ac motor idla ngokuba yinqanaba lesithathu okanye isigaba esinye se-asynchronous kunye ne-synchronous motor.Umlawuli uquka iinxalenye ezintathu, i-converter yebhuloho ehlaziyiweyo, ikhonkco elichanekileyo langoku, kunye neyunithi ye-inverter yesigaba sesithathu.Uhlobo lomthombo wombane we-vfd lolona luxhaphakileyo kwiindawo ezikude.Isiguquli sokuhlaziya sibunjwe njenge-pulse yesigaba sesithandathu se-pulse, ibhulorho egcweleyo ye-diode. Ikhonkco le-Dc liqulathe i-capacitors yokugudisa i-Dc ripple yemveliso kwaye inikezela ngegalelo eliqinileyo kwi-inverter.Imo yolawulo ye-vfd ikakhulu iquka i-V/F, i-SPWM, i-SVPWM .
Uninzi lwezicelo zokulayisha isantya semoto ezilungisiweyo ziqhagamshela ngokuthe ngqo kwisigaba esithathu sobonelelo lwamandla kunokonga amandla ngokusebenzisa i-vfd.Njengoko imithwalo elungisiweyo ibeka i-motor kwi-torque ephezulu yokuqala kunye nokunyuka kwangoku ukuya kuthi ga kwi-8-10 amaxesha omthwalo ogcweleyo wangoku.Ukuqhuba kwe-Ac kunokuthi ngokuthe ngcembe kunyuse i-motor ukuya kwisantya esilinganiselweyo ukunciphisa uxinzelelo lomatshini kunye nombane, ukunciphisa iindleko zokuyilungisa kunye nobukhulu bobomi bemoto kunye nezixhobo eziqhutywayo. Umjelo wangoku malunga namaxesha ayi-1.2 esantya esikalwe yimoto, yehlisa ngokukhawuleza i-inrush yangoku. .
Ulawulo lwenkqubo kunye nencoko yamandla zezona zizathu zokusebenzisa ii-frequency drives.Njengokusebenzisa kwimpompo.Xa kusetyenziswa isantya esilungisiweyo sokuqhuba, iimpompo zisebenza ngokuqhubekayo ngesantya esonyuka njengoko inqanaba lequla elimanzi linyuka, elihambelana nokuphuma komndilili wokungena.
UXi'an Noker Electric uzibophelele ekuboneleleni abathengi ngezisombululo ezipheleleyo zolawulo lokuqalisa iimoto, unazo naziphi na iingxaki zokuqalisa iimoto, nceda uzive ukhululekile ukuqhagamshelana nathi.Siza kukubonelela ngezisombululo zenkqubo.
