1. Indlela ukukhetha servo ngeemoto inyathelo motor ngokuchanekileyo?
Oku ikakhulu ixhomekeke kwi sicelo. Ngokubanzi, kufuneka ukufumanisa: uhlobo umthwalo (umthwalo tye okanye nkqo), torque, inertia, isantya, ukuchaneka, ukukhawulezisa kunye deceleration kunye nezinye iimfuno, iimfuno ulawulo ophezulu (ezifana izibuko isinxulumanisi kunye nonxibelelwano neemfuno), kunye engundoqo indlela yokulawula esi sikhundla, torque okanye isantya indlela. Power supply DC okanye AC amandla, okanye amandla ebhetri, uluhlu ombane. Ukuze ubone umfuziselo motor kunye ehamba drive okanye isilawuli.
- Yintoni umahluko phakathi AC servo ngeemoto motor DC servo?
- Impendulo: motor DC servo yahlulahlulwe ibrashi ngeemoto akukho motor brush.
- Le motor ibhrashi unalo iingenelo ngendleko ephantsi, isakhiwo elula, torque lokuqalisa enkulu, ebanzi isantya uluhlu, ulawulo lula kunye nokugcinwa, kodwa iluncedo ukuba agcine, ukuphazamisana magnetic kunye neemfuno zokusingqongileyo. Ngoko ke ungasetyenziswa izihlandlo mveliso kunye civil eziqhelekileyo ingqalelo kwiindleko.
- BLDCM na umthamo encinane, ubunzima ukukhanya, imveliso enkulu, impendulo ekhawulezayo, ngesantya esiphezulu, inertia encinane, ujikelezo anencasa torque izinzile. Ulawulo sinzima, yaye kulula wabona intellectualization. Imowdi commutation elektroniki guquka, nto leyo inokuba square wave commutation okanye sine wave olwenze. Motor yesondlo free, kahle eliphezulu, iqondo elisezantsi yokusebenza, imitha magnetic incinane kakhulu, ubomi obude, ingasetyenziswa kwiindawo ezahlukahlukeneyo.
- AC servo motor kwakhona injini brushless, nto leyo yahlulahlulwe motor yolunye kunye emgudu munye. Okwangoku, motor yolunye jikelele kusetyenziswa kulawulo motion. It enoluhlu amandla enkulu kwaye ukufezekisa igunya elikhulu. Kwesona santya siphezulu ojikeleza iphantsi kunye inertia elikhulu, yaye kunciphisa ngokukhawuleza kunye nokwanda ngamandla. Ngoko ke, kufanelekile ukuba isicelo nesezantsi speed kunye nokusebenza ezinzileyo; motor olungenangqamaniso iye isantya esiphezulu kunye nokuchaneka ophantsi ngaphezu motor yolunye, nto leyo edla Zisebenziselwa injini yokuluka kwezinto zokusebenza.
- Yintoni ekufuneka ihlawulwe ingqalelo xa usebenzisa servo motor?
- Impendulo: check ngolu hlobo lulandelayo phambi amandla kwi ukusebenza:
a) Enoba ombane amandla supply efanelekileyo (over-ombane kungenzeka ukuba enze umonakalo kwimodyuli drive); ngokuba DC igalelo, + / - wokwephuka kufuneka adityaniswe kakubi, nokuba imodeli mafutha okanye ixabiso isicwangciso zangoku kwi umlawuli drive efanelekileyo (ayinkulwanga kakhulu ekuqaleni);
b) Umgca uphawu yolawulo iya ngokuqinileyo enxulumene, kwaye ingxaki uvikele (ezifana isibini ezijijekileyo) ziya kuqwalaselwa kwi kwisiza zoshishino;
c) Musa ukuqhagamshela zonke iingcingo ekufuneka izakubanodibaniso ekuqaleni, qhagamshela nje zona kwindlela kakhulu basic, uze uqhagamshele kubo ngcembe emva nkqubo iqhuba kakuhle. d) Qinisekisa ukuba uqinisekise ukuba indlela isiseko icacile, okanye sebenzisa engenasigxina umoya endaweni kokuxhuma. e) Phakathi kangangesiqingatha seyure emva kokuqalisa ukusebenza, ngokusondeleyo bagcine imeko injini, ezifana nokuba intshukumo eqhelekileyo, isandi kunye lobushushu Vuka, yaye ngoko nangoko umatshini for hlengiso ukuba nayiphi na ingxaki kufunyanwa.
4 ngaba kunokwenzeka ukulawula ngqo motor servo ngonxibelelwano?
Ewe, loo nto nayo lula. Yinto nje ngesantya. Isetyenziswa izicelo ukuba musa ukuba isantya impendulo kakhulu. Ukuba ufuna iparameters ngokukhawuleza ulawulo impendulo, kungcono ukuba ikhadi ukusetyenziswa servo ulawulo motion. Ngokubanzi, liye DSP kunye-high speed yesekethe logic processing ukuphumeza-high speed kunye nolawulo motion eliphezulu-ngqo. Ezifana s ukukhawulezisa, multi axis zelwe, njl 5. Ngaba inxalenye zokukhowuda ye servo motor ukuba zezikhali?
Akuvunyelwe ukuba ibattery, kuba chip zwi kwi khowudi disk Kulula sihlwahlwaz, yaye emva kokungena eluthulini, ubomi nkonzo kunye nokuchaneka akayi akunakuqinisekiswa, nto leyo ifuna ukulungiswa yobungcali.
- Ngaba motor servo ukuba zezikhali yolondolozo okanye refitted?
Kubhetele ukuba ubuyele nezityalo yesondlo. Yinto nzima ukuyifaka motor abuyele kwisimo sayo sokuqala ngaphandle izixhobo zobungcali emva disassembling imoto, kwaye kugqitywe phakathi stators ye motor alunakuqinisekiswa. Le ukusebenza steel magnetic ibhuqiwe, miphumela ukulahlekelwa excitation, kwaye torque ngeemoto eliphantsi kakhulu.
- Indlela ukuba ukhethe unikezelo igunya elifanelekileyo isicelo?
Kucetyiswa ukuba ombane unikezelo lwamandla yi-10% - 50% ngaphezulu kokukhulu efunekayo ombane. Le pesenti kuyahlukana nedlela KT, Ke, kwaye drop ombane kule nkqubo. Ixabiso yangoku umqhubi kufuneka elaneleyo lokuzisa eneji efunekayo ukuze isicelo. Khumbula ukuba ombane imveliso ye umqhubi yahlukile ukusuka ombane unikezelo, ngoko ke imveliso sangoku umqhubi yahlukile input yangoku. Ukuze kumiselwe unikezelo lwangoku ezifanelekileyo, kubalulekile ukubala zonke iimfuno amandla kwesi sicelo, kunye nokwandisa nge-5%. Ngokutsho formula I = P / V, ixabiso efunekayo yangoku zingafumaneka.

- Indlela ukuyincula umqhubi servo kunye servo nkqubo?
- Ukuba akukho bodwa phakathi AC umbane kunye nomqhubi DC ibhasi (ezifana sombane), musa zokunculwa kwizibuko non ekwanti beebhasi DC okanye uphawu non ekwanti, nto leyo inokwenza umonakalo izixhobo kunye yokwenzakala emzimbeni. Ngenxa yokuba ombane AC eqhelekileyo ayikho emhlabeni, kungakhona ombane aphezulu phakathi emhlabeni ibhasi DC kunye nomhlaba.
- Kwiinkqubo ezininzi servo, wonke umhlaba kwaye umhlaba eqhelekileyo oxhulumene kwi ekupheleni umqondiso. Le loop Umhlaba eyenziwe ngeendlela uxhulumaniso ezininzi ngokulula abachatshazelwa yi ingxolo kwaye yenza flow kwiindawo reference ezahlukeneyo.
- Ukuze ukugcina ombane njalo umyalelo reference, umqondiso umqhubi liqhagamshelene umqondiso esisebenza. Siya kuphinda kuqhagamshelwa emhlabeni yonikezelo amandla angaphandle, nto leyo eza kuchaphazela ukusebenza isilawuli kunye umqhubi (ezifana 5V amandla ezinawo zakho zokukhowuda). d. Kukho iindlela ezininzi ukuyincula vha. Umhlaba uvikele echanekileyo na kwi reference olunokubakho indawo ngaphakathi ukujikeleza kwalo. Le ngongoma kuxhomekeke ukuba umthombo ingxolo ngumamkeli zi- yathotywa okanye idada ngexesha elifanayo. Qinisekisa ukuba ikhaka lihlala kwindawo enye ukuze ngoku emhlabeni akuthethi kuqukuqela ikhaka.
- Kutheni na reducer kunye motor umdlalo kwindawo torque eqhelekileyo?
Ukuba uqwalasela torque ezona eveliswa yi motor ngokusebenzisa reducer, kuphantse ezininzi zokunciphisa uya kude kudlula inqanaba torque le reducer.
Ukuba sifuna ukuba kuyilwe reducer ngamnye ukutshatisa torque epheleleyo, kuya kuba zizifundo ezininzi kakhulu amagiya angaphakathi reducer (umthamo omkhulu kunye nezinto ezininzi).
Oku kuya kwenza eliphezulu ixabiso imveliso esaphula i "umsebenzi omkhulu, umthamo omncinane" umgaqo imveliso.
Isakhiwo jikelele robot mveliso inkqubo servo yombane ulawulo ezintathu evaliweyo-ngokwenzekayo, loop angala ngoku, isantya loop nesikhundla loop. Ngokubanzi, kuba AC umqhubi servo, ulawulo sikhundla, ulawulo isantya, ulawulo torque kunye neminye imisebenzi zinokuphunyezwa ngokubeka ngesandla parameters zayo umsebenzi lwangaphakathi.
