Umqhubi we-Servo,ekwabizwa ngokuba yi "servo controller" okanye "servo amplifier", luhlobo lwesilawuli esisetyenziselwa ukulawula iimotor zeservo. Umsebenzi wayo ufana nowoguqulelo oluphindaphindayo olusebenza kwiimotor eziqhelekileyo ze-AC, kwaye luyinxalenye yenkqubo ye-servo. Ngokubanzi, iimotor ze-servo zilawulwa ngeendlela ezintathu: isikhundla, isantya, kunye ne-torque ukufezekisa ukuchaneka okuphezulu kwenkqubo yothumelo.
1, Ukuhlelwa kweenjini ze-servo
Yahlulwe yangamacandelo amabini: iimotor ze-DC kunye ne-AC servo motors, iimotor ze-AC servo zahlulwe ngakumbi kwiimotor ze-servo ezilinganayo kunye neemotor ze-servo ezihambelanayo. Okwangoku, iinkqubo ze-AC ngokuthe ngcembe zithatha indawo yeenkqubo ze-DC. Xa kuthelekiswa neenkqubo ze-DC, ii-motor servo ze-AC zineengenelo ezifana nokuthembeka okuphezulu, ukuchithwa kakuhle kobushushu, umzuzu omncinci we-inertia, kunye nokukwazi ukusebenza phantsi kweemeko zombane ophezulu. Ngenxa yokunqongophala kweebhrashi kunye nezixhobo zokuqhuba, inkqubo ye-AC yabucala yomncedisi iye yaba yinkqubo ye-servo brushless. Iimotor ezisetyenziswa kuyo zii-brushless cage asynchronous motors kunye nemagnethi esisigxina ye-synchronous motors.
1. Iimotor ze-DC servo zahlulwe zaba zii-motor brushed and brushless motors
① Iinjini zebrushless zinexabiso eliphantsi, ulwakhiwo olulula, itorque enkulu, uluhlu olubanzi lolawulo lwesantya, ulawulo olulula, kwaye lufuna ukulungiswa. Nangona kunjalo, kulula ukuzigcina (ukutshintsha iibrashi zekhabhoni), zivelise ukuphazamiseka kwe-electromagnetic, kwaye zineemfuno zendawo yokusebenza. Ngokuqhelekileyo zisetyenziselwa uvakalelo lweendleko eziqhelekileyo kwimizi-mveliso nakwizicelo zasekuhlaleni;
② Iinjini ze-brushless zinesayizi encinci, ubunzima obulula, imveliso enkulu, impendulo ekhawulezayo, isantya esiphezulu, inertia encinci, i-torque ezinzileyo kunye nokujikeleza okugudileyo, ulawulo oluntsonkothileyo, ubukrelekrele, iindlela eziguquguqukayo zokutshintsha kwe-elektroniki, zinokuba ngamaza esquare okanye i-sine wave commutation, ukugcinwa kwasimahla, esebenzayo kunye nokugcina amandla, imitha ye-electromagnetic ephantsi, ukunyuka kobushushu obuphantsi, ubomi benkonzo ende, kwaye ilungele iindawo ezahlukeneyo.
2. Iimpawu zeentlobo ezahlukeneyo zeenjini ze-servo
1. Izinto eziluncedo kunye nezingeloncedo zeenjini ze-DC servo
Izinto eziluncedo: Ukulawulwa kwesantya esichanekileyo, iimpawu zesantya esomeleleyo, umgaqo olula wokulawula, ukusetyenziswa ngokulula, kunye nexabiso elifikelelekayo.
Ukungalungi: Ukutshintshwa kwebrashi, ukunciphisa isantya, ukuchasana okongeziweyo, ukuveliswa kwamasuntswana okunxiba (ayifanelekanga indawo engenathuli kunye neendawo eziqhumayo)
2. Izinto eziluncedo kunye nezingeloncedoIinjini ze-AC servo
Izinto eziluncedo: Iimpawu zokulawula isantya esilungileyo, ulawulo olugudileyo lunokufezekiswa kulo lonke uluhlu lwesantya, phantse akukho oscillation, ukusebenza kakuhle okungaphezulu kwe-90%, isizukulwana esisezantsi sobushushu, ukulawulwa kwesantya esiphezulu, ulawulo lwendawo echanekileyo (kuxhomekeke ekuchanekeni kwe-encoder), inokufezekisa i-torque eqhubekayo ngaphakathi kwendawo yokusebenza elinganisiweyo, inertia ephantsi, ingxolo ephantsi, ukungabikho kwebrashi yokugqoka, ukugcinwa kwamahhala (ekulungele uthuli kunye neendawo eziqhumayo).
Ukungalungi: Ulawulo luyinkimbinkimbi, kwaye iiparitha zomqhubi kufuneka zihlengahlengiswe kwi-site ukumisela iiparamitha ze-PID, ezifuna i-wiring eninzi.
Okwangoku, iidrive ze-servo eziqhelekileyo zisebenzisa i-digital signal processors (DSP) njengesiseko solawulo, esinokufikelela kwi-algorithms yokulawula enzima, i-digitization, i-networking, kunye nobukrelekrele. Izixhobo zamandla ngokubanzi zisebenzisa iisekethe zokuqhuba eziyilwe ngeemodyuli zamandla akrelekrele (IPM) njengondoqo. I-IPM idibanisa iisekethe zokuqhuba ngaphakathi kwaye iphinde ibe neesekethe zokubona iimpazamo kunye nokukhusela i-overvoltage, i-overcurrent, i-overheating, i-undervoltage, njl. Iyunithi yokuqhuba amandla kuqala ilungisa igalelo lesigaba sesithathu okanye umbane oyintloko ngesigaba esithathu esipheleleyo sesekethe yokulungisa ibhulorho ukufumana amandla ahambelanayo eDC. Emva kokulungiswa, inqanaba lesithathu okanye amandla amakhulu asetyenziselwa ukuqhuba inqanaba lesithathu lemagnethi esisigxina ye-AC servo motor ngesigaba esithathu sine-PWM yomthombo wombane woguqulo lombane loguqulo. Yonke inkqubo yeyunithi yokuqhuba amandla inokuchazwa ngokulula njengenkqubo ye-AC-DC-AC. Isekethe ye-topology engundoqo yeyunithi yokubuyisela (AC-DC) yibhlorho egcweleyo enesigaba esithathu engalawulwayo sesekethe yokubuyisela.
1. Iingcingo zomqhubi
I-servo drive ikakhulu ibandakanya unikezelo lwamandla esekethe yolawulo, unikezelo lombane lwesekethe yolawulo oluphambili, unikezelo lwamandla ombane we-servo, igalelo lomlawuli CN1, i-encoder interface CN2, kunye ne-CN3 edibeneyo. Unikezelo lwamandla olawulo lwesiphaluka lunikezelo lwamandla e-AC yesigaba esisodwa, kwaye amandla okufakelwa anokuba yinqanaba elinye okanye inqanaba lesithathu, kodwa kufuneka libe yi-220V. Oku kuthetha ukuba xa igalelo lezigaba ezithathu lisetyenziswa, unikezelo lwethu lwamandla amanqanaba amathathu kufuneka ludityaniswe nge-transformer transformer. Kubaqhubi bamandla aphantsi, inokuqhutyelwa ngokuthe ngqo kwisigaba esisodwa, kwaye indlela yokudibanisa yesigaba esisodwa kufuneka ixhunywe kwii-terminals ze-R kunye ne-S. Khumbula ukuba ungaqhagamshele iziphumo ze-servo motor U, V, kunye ne-W kumbane oyintloko wesekethe, njengoko inokutshisa umqhubi. I-CN1 port isetyenziselwa ukudibanisa umlawuli wekhompyutheni ephezulu, ukubonelela ngegalelo, imveliso, i-encoder ABZ isiphumo sesigaba sesithathu, kunye nemveliso ye-analog yeempawu ezahlukeneyo zokubeka iliso.
2. Iingcingo ze-encoder
Ukususela kulo mzobo ungasentla, kunokubonwa ukuba sisebenzise kuphela i-5 ye-terminals ezisithoba, kubandakanywa ucingo olulodwa lokukhusela, iingcingo zamandla amabini, kunye neempawu ezimbini zonxibelelwano lwe-serial (+-), ezifana nocingo lwe-encoder yethu eqhelekileyo.
3. Izibuko lonxibelelwano
Umqhubi uqhagamshelwe kwiikhompyuter eziphezulu ezifana ne-PLC kunye ne-HMI nge-CN3 port, kwaye ilawulwa ngokusebenzisaUnxibelelwano lweMODUS. I-RS232 kunye ne-RS485 ingasetyenziselwa unxibelelwano.
