Umgaqo osebenzayo we-AC servo motor:
Xa i-AC servo motor ingenawo amandla olawulo, kukho kuphela i-pulsating field magnetic eyenziwa yi-excitation winding kwi-stator, kwaye i-rotor imile.Xa kukho i-voltage yokulawula, intsimi yamagnetic ejikelezayo iveliswa kwi-stator, kwaye i-rotor ijikeleza ecaleni kwendlela yamagnetic ejikelezayo.Xa umthwalo uhlala, isantya semoto sitshintsha kunye nobukhulu bombane wokulawula.Xa isigaba solawulo lombane sichasene, i-AC servo I-motor iya kubuya umva.Nangona umgaqo osebenzayo we-AC servo motor ufana nowokwahlukana kwesigaba esisodwa se-asynchronous motor, ukuxhathisa kwe-rotor yangaphambili kukhulu kakhulu kunokokugqibela.Ke ngoko, xa kuthelekiswa nomatshini omnye asynchronous motor, i-servo motor ineempawu ezintathu ezibalulekileyo:
1. I-torque enkulu yokuqalisa
Ngenxa yokumelana ne-rotor enkulu, ijika le-torque ye-torque iboniswe kwi-curve 1 kuMfanekiso we-3, ohluke ngokucacileyo kwi-torque ye-curve ye-2 yeenjini eziqhelekileyo ze-asynchronous.Inokwenza umlinganiselo obalulekileyo wokutyibilika i-S0> 1, ongenzi nje ukuba uphawu lwe-torque (uphawu lomatshini) lusondele kumgca, kodwa lune-torque enkulu yokuqala.Ngoko ke, xa i-stator ine-voltage yokulawula, i-rotor ijikeleza ngokukhawuleza, eneempawu zokuqalisa ngokukhawuleza kunye novakalelo oluphezulu.
2. Uluhlu olubanzi lokusebenza
3. Akukho siganeko sokujikeleza
Kwimoto ye-servo ekusebenzeni okuqhelekileyo, nje ukuba i-voltage yokulawula ilahlekile, i-motor iya kuyeka ukusebenza ngokukhawuleza.Xa i-servo motor ilahlekelwa yi-voltage yolawulo, ikwimo yokusebenza yesigaba esinye.Ngenxa yokumelana okukhulu kwe-rotor, iimpawu ezimbini ze-torque (i-T1-S1, i-T2-S2 i-curves) eyenziwa ngamacandelo amabini ajikelezayo ajikelezayo ajikelezayo kwi-stator kunye nesenzo se-rotor) kunye neempawu ze-torque zokwenziwa (TS) igophe) Amandla emveliso ye-AC servo motor ngokuqhelekileyo yi-0.1-100W.Xa i-frequency yamandla i-50Hz, i-voltages yi-36V, 110V, 220, 380V;xa i-frequency yamandla i-400Hz, i-voltages yi-20V, i-26V, i-36V, i-115V njalo njalo.I-AC servo motor ihamba kakuhle ngengxolo ephantsi.Kodwa uphawu lokulawula alunamgca, kwaye ngenxa yokuba ukuxhathisa kwe-rotor kukhulu, ilahleko inkulu, kwaye ukusebenza kakuhle kuphantsi, xa kuthelekiswa ne-DC servo motor yomthamo ofanayo, inkulu kwaye inzima, ngoko ifanelekile kuphela. kwiinkqubo zokulawula amandla amancinci ka-0.5-100W.
Okwesibini, umahluko phakathi kwe-AC servo motor kunye ne-DC servo motor:
Iinjini ze-DC servo zahlulwe zaba ziimotor ezixutyiweyo kunye neebrashi.Iimoto ezixutyiweyo zinexabiso eliphantsi, zilula ngolwakhiwo, zinkulu ekuqaliseni itorque, zibanzi kuluhlu lolawulo lwesantya, kulula ukuzilawula, kwaye zifuna ukulungiswa, kodwa kulula ukuzigcina (zitshintshe iibhrashi zekhabhoni), zivelisa ukuphazamiseka kombane, kwaye zineemfuno okusingqongileyo.Ke ngoko, inokusetyenziswa kwiimeko eziqhelekileyo zeshishini kunye nezasekuhlaleni ezinovelwano kwiindleko.Injini ye-brushless incinci ngobukhulu, ilula ngobunzima, imveliso enkulu, ikhawuleza ngokuphendula, isantya esiphezulu, incinci kwi-inertia, igudileyo ekujikelezeni kwaye izinzile kwi-torque.Ulawulo lunzima, kwaye kulula ukuqonda ubukrelekrele.Indlela yayo yokutshintsha i-elektroniki iyaguquguquka, kwaye inokuba sisikwere sokutshintshwa kwamaza okanye i-sine wave commutation.Imoto ayilungiswanga, inokusebenza okuphezulu, ubushushu obuphantsi bokusebenza, imitha ye-electromagnetic ephantsi, ubomi obude, kwaye inokusetyenziswa kwiindawo ezahlukeneyo.
Iinjini ze-AC servo zahlulwe kwiimotor ezihambelanayo kunye ne-asynchronous.Okwangoku, ii-synchronous motors zisetyenziswa ngokubanzi kulawulo lwentshukumo.Uluhlu lwalo lwamandla lukhulu kwaye lunokufikelela kumandla amakhulu.Inertia enkulu, isantya esisezantsi sokujikeleza, kwaye iyancipha ngokukhawuleza njengoko amandla enyuka.Ngoko ke, ifanelekile kwizicelo ezihamba kakuhle kwizantya eziphantsi.
I-rotor ngaphakathi kwe-servo motor yimagnethi esisigxina.I-U/V/W yombane wezigaba ezithathu ezilawulwa ngumqhubi zenza i-electromagnetic field.I-rotor ijikeleza phantsi kwesenzo sale ntsimi yamagnetic.Kwangaxeshanye, i-encoder yemoto ibuyisela umqondiso kumqhubi.Amaxabiso athelekiswa nokulungelelanisa i-angle apho i-rotor ijika khona.Ukuchaneka kwe-servo motor kuxhomekeke ekuchanekeni (inani lemigca) ye-encoder.
Ngokuqhubela phambili okuqhubekayo kwe-automation yemizi-mveliso, imfuno yesoftware ezenzekelayo kunye nezixhobo zehardware zihlala ziphezulu.Phakathi kwazo, imakethi yerobhothi yasekhaya ikhula ngokuthe ngcembe, kwaye ilizwe lam liye laba yeyona ntengiso inkulu emhlabeni.Ngexesha elifanayo, iqhuba ngokuthe ngqo imfuno yemarike yeenkqubo ze-servo.Okwangoku, iimotor ze-AC kunye ne-DC servo ezinetorque ephezulu yokuqalisa, i-torque enkulu kunye ne-inertia ephantsi zisetyenziswa kakhulu kwiirobhothi zoshishino.Ezinye iimotor, ezinjengeemotor ze-AC servo kunye ne-stepper motors, nazo ziya kusetyenziswa kwiirobhothi zamashishini ngokweemfuno ezahlukeneyo zesicelo.
