Masu samar da naúrar ba da amsa suna tunatar da ku: Driver-mita mai canzawa (VFD) yana sarrafa gudu da aiki na motar ta hanyar daidaita mita da girman ƙarfin fitarwa. Musamman, VFD yana sarrafa saurin motar ta hanyar matakai masu zuwa:
Sayen siginar shigarwa: VFD ta fara tattara siginar shigarwa daga tsarin sarrafawa ko tsarin aiki, gami da sigogi kamar saitunan saurin da ake buƙata, yanayin aiki, da sauransu.
Lissafin sauri: Dangane da siginar shigarwa da algorithm na sarrafawa na ciki na VFD, VFD yana ƙididdige saurin da injin ya kamata ya yi aiki a halin yanzu.
Ƙirƙirar siginonin PWM: Dangane da saurin ƙididdigewa, VFD yana haifar da siginar PWM daidai (modulation mai faɗin bugun jini).
Modulation Width Julse: Siginar PWM yana wucewa ta cikin tsarin juzu'in juzu'in juzu'in juzu'i kuma ya canza shi zuwa jerin siginonin bugun jini. Za'a iya sarrafa nisa da tazara na bugun jini gwargwadon saurin jujjuyawar da ake so.
Daidaita wutar lantarki na fitarwa: Siginar bugun jini ta hanyar da'irar fitarwa tana daidaita girman da mitar ƙarfin fitarwa na VFD. Mitar ƙarfin fitarwa shine saurin da ake so.
Motar wuta: Ana ba da wutar lantarki mai fitarwa zuwa injin ta tashar fitarwa ta VFD. Motar tana aiki a daidai gudu gwargwadon ƙarfin lantarki da mitar da VFD ke bayarwa.
Ta hanyar daidaita yawan mita da girman ƙarfin fitarwa, VFD na iya cimma daidaitaccen sarrafa saurin sauri don saduwa da buƙatun yanayin aiki daban-daban da haɓaka ingantaccen aiki da daidaiton sarrafa injin.
