Ukutshintsha inkqubo yokuthandabuza yokuqhuba imoto inokuthembeka okuphezulu kunye nokusebenza okugqwesileyo. Luhlobo olutsha lwenkqubo yokuqhuba kwaye ngokuthe ngcembe ithatha indawo yezinye iimveliso zokulawula isantya kwindawo yoshishino. Eli nqaku lithelekisa le nkqubo kunye ne-asynchronous motor variable frequency regulation system yesantya ukubona ukuba yintoni umahluko phakathi kwezi zimbini.
1. Ukuthelekiswa kweenjini zombane: I-motor yokungafuni ukutshintshiselwa yomelele kwaye ilula kune-asynchronous motor. Inzuzo yayo egqwesileyo kukuba akukho moya kwi-rotor, ngoko ke akuyi kubakho ukuphosa kakubi, ukungaphumeleli kokukhathala kunye nesantya esiphezulu esibangelwa yi-cage rotor ye-asynchronous motor. Ngenxa yothintelo kunye neminye imiba, iimotor ezitshintshayo zokwenqena zihlala zisezantsi kwindleko yokuvelisa kwaye kunzima kakhulu ukwenza kuneemotor ze-squirrel-cage asynchronous.
2. Ukuthelekiswa kwee-inverters: Iinguqu zamandla eziguquguqukayo ezitshintshileyo zinenzuzo ngaphezu kwee-asynchronous motor PWM inverters ngokwexabiso. Uphawu olutshintshiweyo lwenkqubo yokutshixa imotor drive kukuba inqanaba langoku liqukuqela kwicala elinye kwaye alinanto yakwenza ne torque, ukuze isigaba ngasinye sisebenzise isixhobo esinye esiphambili sokutshintsha ukulawula inkqubo ukufezekisa ukusebenza kweequadrant ezine, ngelixa. I-asynchronous motor PWM inverter inayo Ukongeza, ngenxa yokuba ezona zixhobo zokutshintsha eziphambili ze-asynchronous motor voltage-type PWM inverter ziqhagamshelwe kunikezelo lwamandla nganye nganye, kukho impazamo enokwenzeka yokuba iingalo zebhulorho ephezulu nezisezantsi ziqhagamshelwe ngokuthe ngqo ngenxa ukubangela ubuxoki kunye nesekethe ephambili imfutshane-ijikelezwe.
3. Uthelekiso lwenkqubo yokusebenza kwenkqubo: Imotor etshintshileyo yokungafuni ukuya enentonga ephindwe kabini ithelekiswa ne-asynchronous motor PWM inverter, ngakumbi kumlinganiselo wetorque / umzuzu we-inertia. Ukongeza, i-motor ye-reluctance etshintshiweyo ineempawu ze-motor ye-DC esebenza ngokuphezulu, kwaye ulawulo lubhetyebhetye kwaye lulungele kunenkqubo yokulawula isantya esiguqukayo. Iyakwazi ukufumana iitorque ezahlukeneyo ngokulawula ukuvala nokuvula amaxesha okujika kwesigaba. /iimpawu zesantya.
Ngokungeniswa kweli phepha, akukho nzima ukubona ukuba inkqubo yokutshitsha yokungafuni ukuqhubela phambili ibonise ukhuphiswano olumandla kwaye ineenzuzo ezinkulu xa kuthelekiswa neenkqubo zemveli.
