Isebenza njani i-servo drive:
Okwangoku, iidrive ze-servo eziphambili zisebenzisa iiprosesa zesiginali yedijithali (DSP) njengeyona nto iphambili yolawulo, enokuqonda i-algorithms yolawulo oluntsonkothileyo kwaye iqonde idijithali, inethiwekhi kunye nobukrelekrele.Izixhobo zamandla ngokubanzi zamkela isekethe yokuqhuba eyilwe ngemodyuli yamandla akrelekrele (IPM) njengondoqo.Qala isiphaluka ukunciphisa impembelelo kumqhubi ngexesha lenkqubo yokuqalisa.
Iyunithi yokuqhuba amandla kuqala ilungisa igalelo lamandla esigaba sesithathu okanye amandla amakhulu ngokusebenzisa inqanaba lesithathu lebhulorho yokulungisa isekethe yokufumana amandla ahambelanayo eDC.Emva kokulungiswa kombane wamanqanaba amathathu okanye umbane oyintloko, inqanaba lesithathu lemagnethi esisigxina ye-AC servo motor iqhutywa luguqulo oluphindaphindiweyo lwesigaba esithathu sohlobo lombane lwe-sinusoidal PWM.Yonke inkqubo yeyunithi yokuqhuba amandla inokutshiwo ngokulula ukuba yinkqubo ye-AC-DC-AC.Isekethe ephambili ye-topological yeyunithi yokulungiswa (AC-DC) yinqanaba lesithathu lebhulorho engalawulwayo yokulungiswa kwesekethe.
Ngokusetyenziswa komgangatho omkhulu weenkqubo ze-servo, ukusetyenziswa kwe-servo drives, i-servo drive debugging, kunye nokugcinwa kwe-servo drive yonke yimiba ebalulekileyo yobugcisa kwiidrive ze-servo namhlanje.Bayanda nangakumbi ababoneleli ngeenkonzo zobuchwepheshe bolawulo lwemizi-mveliso benze uphando olunzulu lobuchwephesha kwii-servo drives.
Iidrive zeServo ziyinxalenye ebalulekileyo yolawulo lwentshukumo yanamhlanje kwaye zisetyenziswa kakhulu kwizixhobo ezizisebenzelayo ezifana neerobhothi zoshishino kunye namaziko omatshini eCNC.Ngokukodwa i-servo drive esetyenziselwa ukulawula i-AC yemagnethi esisigxina ye-synchronous motor iye yaba yindawo yophando ekhaya nakwamanye amazwe.Okwangoku, isantya, kunye nesikhundla se-3 i-algorithms yokulawula i-loop evaliweyo esekelwe kulawulo lwe-vector isetyenziswa ngokubanzi kuyilo lwe-AC servo drives.Ingaba isantya sokuvala i-loop design kule algorithm sinengqiqo okanye ayidlala indima ephambili ekusebenzeni kwayo yonke inkqubo yokulawula i-servo, ngokukodwa ukulawulwa kwesantya.
Iimfuno zeServo drive system:
1. Uluhlu olubanzi lwesantya
2. Ukuchaneka kokubeka okuphezulu
3. Ukuqina okwaneleyo kokuhanjiswa kunye nokuzinza kwesantya esiphezulu.
4. Ukwenzela ukuqinisekisa imveliso kunye nomgangatho wokusetyenzwa,ngaphezu kokufuna ukuchaneka kokubeka okuphezulu, iimpawu ezintle zokuphendula ngokukhawuleza nazo ziyafuneka, oko kukuthi, impendulo kwimiqondiso yomyalelo wokulandelela iyadingeka ukuba ikhawuleze, kuba inkqubo ye-CNC idinga ukongezwa kunye nokuthabatha xa uqala kunye ne-braking.Ukukhawuleza kukhulu ngokwaneleyo ukucutha ixesha lenkqubo yenguqu yenkqubo yokutya kunye nokunciphisa impazamo yenguqu yecontour.
5. Isantya esiphantsi kunye ne-torque ephezulu, umthamo oqinileyo wokulayisha
Ngokuqhelekileyo, umqhubi we-servo unomthamo wokulayisha ngaphezulu kwamaxesha e-1.5 ngaphakathi kwemizuzu embalwa okanye isiqingatha seyure, kwaye unokulayishwa ngokuphindwe ka-4 ukuya kwe-6 ngexesha elifutshane ngaphandle komonakalo.
6. Ukuthembeka okuphezulu
Kuyafuneka ukuba inkqubo ye-feed drive yezixhobo zoomatshini be-CNC inokuthembeka okuphezulu, ukuzinza okuhle kokusebenza, ukuguquguquka okunamandla kokusingqongileyo kwiqondo lokushisa, ukufuma, ukungcangcazela, kunye nobuchule obunamandla bokuchasana nokuphazamiseka.
Iimfuno ze-servo drive yemoto:
1. I-motor inokuhamba kakuhle ukusuka kwisantya esisezantsi ukuya kwisantya esiphezulu, kwaye ukuguquguquka kwe-torque kufuneka kube kuncinci, ngokukodwa kwizantya eziphantsi ezifana ne-0.1r / min okanye ngaphantsi, kusekho isantya esizinzile ngaphandle kokukhasa.
2. I-motor kufuneka ibe nomthamo omkhulu wokulayisha ixesha elide ukuhlangabezana neemfuno zesantya esiphantsi kunye ne-torque ephezulu.Ngokubanzi, iinjini ze-DC servo kufuneka zilayishwe kakhulu amaxesha ama-4 ukuya kuma-6 kwimizuzu embalwa ngaphandle komonakalo.
3. Ukuze kuhlangatyezwane neemfuno zokuphendula ngokukhawuleza, i-motor kufuneka ibe nomzuzu omncinci we-inertia kunye ne-torque enkulu ye-stall, kwaye ibe nexesha elincinci eliqhelekileyo kunye nokuqalisa i-voltage ngokusemandleni.
4. I-motor kufuneka ikwazi ukumelana nokuqala rhoqo, ukunyathela kunye nokujikeleza umva.
