Servo motor eyisisekelo ulwazi

Igama elithi "servo" livela egameni lesiGreki elithi "isigqila". "I-servo motor" ingaqondakala njengemoto elalela ngokuphelele umyalo wesiginali yokulawula: ngaphambi kokuba isiginali yokulawula ithunyelwe, i-rotor iyami; Lapho kuthunyelwa isiginali yokulawula, i-rotor ijikeleza ngokushesha; Lapho isinali yokulawula inyamalala, i-rotor ingama ngokushesha.

I-servo motor yimoto encane esetshenziswa njenge-actuator kudivayisi yokulawula ezenzakalelayo. Umsebenzi wayo ukuguqula isiginali kagesi ibe yi-angular noma i-angular velocity ye-shaft ejikelezayo.

I-Servo Motors ihlukaniswe izigaba ezimbili: AC Servo kanye ne-DC Servo

Isakhiwo esiyisisekelo se-AC Servo motor sifana naleso somoto we-AC Ukungena (imoto ye-asynchronous). Kunezinhlobo ezimbili zokuxoxa ze-WF futhi alawule i-Windings Wcowf enokuthunyelwa kwesigaba sesigaba esingu-90 ° i-angle engela esitsheni, exhunywe ku-ac ac voltage, futhi usebenzise i-ac voltage noma ushintsho lwesigaba esisetshenziselwa ukulawula ukusebenza kwemoto. I-AC Servo Motor inezimpawu zokusebenza okuzinzile, Ukulawulwa okuhle, ukuphendula okusheshayo, ukuzwela okuphezulu, nezinkomba ezingezinhle ezingekho ngaphansi kwezimpawu ezi-10% kuya ku-15% kuya ku-15% kuya ku- 15%

Isakhiwo esiyisisekelo se-DC Selvo motor sifana nesemoto evamile ye-DC. I-motor Speed ​​n = E / K1J = (UA-IARA) / K1J, lapho i-armature counter electromotive, kepha i-UA i-armature, i-armature i-armature, ukuguqula i-armature, kuguqula i-armature, kuguqula indlela yokulawula i-armature motor ngokuvamile isetshenziswa. Emotweni yaphakade ye-MAGNET DC Servo Motor, ukuphefumula kwe-experition kuthathelwa indawo yizinkathi zaphakade, futhi i-flux kazibuthe φ ihlala njalo. . I-DC Selvo Motor inezici ezinhle zokulawulwa okuqondile kanye nempendulo yesikhathi esisheshayo.

Izinzuzo kanye nokubi kwama-DC Servo Motors

Izinzuzo: Ukulawulwa kwejubane okunembile, i-torque eqinile kanye nezimpawu zesivinini, imigomo elula yokulawula, okulula ukuyisebenzisa, nentengo eshibhile.

Okubi

Izinzuzo kanye nokubi kwe-AC Servo Motor

Izinzuzo: Izici ezinhle zokulawula isivinini, ukulawula okubushelelezi kulo lonke uhla lwesivinini, cishe akukho mbono, ukusebenza okuphezulu, umsindo ophansi, umsindo ophansi, indawo ephansi, indawo ephansi, indawo ephansi, izindawo eziqhumayo)

Okubi: Ukulawulwa kuyinkimbinkimbi ngokwengeziwe, amapharamitha we-drive adinga ukulungiswa esizeni ukunquma amapharamitha e-PID, futhi ukuxhumana okuningi kuyadingeka.

I-DC Servo Motors ihlukaniswe ngama-motor ahlanganisiwe futhi angenamkhawulo

Ama-motors ahlanganisiwe aphansi ngezindleko, alula ngesakhiwo, enkulu ekuqaleni kwe-torque, okulula ukuyilawula, adinge ukulungiswa kwe-electronnetic), akhiqize izidingo zemvelo ezijwayelekile nezimboni ezivamile.

Ama-motors angenamkhawulo asayizi futhi akhanya ngesisindo, ephezulu ekuphumeni nasekushesheni ngokuphendula, asheshe akwazi ukujikeleza, ukulungiswa kwamandla okujikeleza, ukuqina kwe-electromagnetic, ukuthuthuka okuncane kwe-electromagnetic, ukunyuka okuphansi kwe-electromagnetic, i-live ephansi, ilungele izindawo ezahlukene.

I-AC Servo Motors nayo i-motors engenamkhawulo, ehlukaniswe ngama-motorsronous ne-asynchronous motors. Njengamanje, ama-motors avumelanayo ajwayele ngokuvamile asetshenziswa ekulawulweni kokunyakaza. Uhla lwamandla lukhulu, amandla angaba mkhulu, i-inertia inkulu, ijubane eliphezulu liphansi, futhi ijubane liyanda ngokwanda kwamandla. I-Uniform -Speed ​​Descent, ilungele izikhathi eziphansi eziphansi nezibushelelezi.

I-rotor ngaphakathi kwe-servo motor inguzibuthe ongapheli. Umshayeli ulawula u / v / w ezintathu - Isigaba sikagesi ukwakha insimu ye-electromagnetic. I-rotor ijikeleza ngaphansi kwesenzo sale nkambu kazibuthe. Ngasikhathi sinye, i-Encoder eza neMoto idlulisela isiginali yempendulo kumshayeli. Amanani aqhathaniswa nokulungisa i-angle yokujikeleza kwe-rotor. Ukunemba kwemoto ye-servo kuncike ekunembeni kwe-encoder (inani lemigqa).

Iyini imoto ye-servo motor? Zingaki izinhlobo? Yiziphi izici ezisebenzayo?

Impendulo: Imoto ye-servo motor, eyaziwa nangokuthi i-Motor Executive Motor, isetshenziswa njenge-actuator ohlelweni lokulawula okuzenzakalelayo ukuguqula isiginali kagesi esitholakele ekuhanjisweni kwe-angular shaft.

I-Servo Motors ihlukaniswe izigaba ezimbili: DC kanye ne-AC Servo Motors. Izici zabo eziphambili ukuthi akukho ukuzivuselela ukuzibandakanya lapho i-voltage voltage ingu-zero, futhi ijubane lincipha ngejubane elifanayo ngokunyuka kwe-torque.

Uyini umehluko ekusebenzeni phakathi kwe-AC Servo Motor ne-DC Servo Motor?

Impendulo: Ukusebenza kwe-AC Servo Motor kungcono, ngoba i-AC Servo ilawulwa yigagasi le-sine kanye ne-torque ripple incane; Ngenkathi i-rushaless DC Selso ilawulwa yigagasi le-trapezoidal. Kepha ukulawulwa kwe-rushiless DC Selto kulula kakhulu futhi kushibhile.

Ukuthuthukiswa okusheshayo kwe-Greent Magnet AC Servo Drazy Technology kwenze uhlelo lwe-DC Servo lubhekane nenkinga yokuqedwa. Ngokuthuthukiswa kobuchwepheshe, ubuchwepheshe baphakade be-Magnet AC Servo Drive buthole intuthuko evelele, futhi abakhiqizi bakagesi abadumile emazweni ahlukahlukene baqhubeka nochungechunge olusha lwe-AC Servo Motors ne-Servo Drives. Uhlelo lwe-AC Servo lube yisiqondisi esikhulu sentuthuko sohlelo lwe-servor lokusebenza lomsebenzi ophakeme lwanamuhla, okwenza uhlelo lwe-DC Servo lubhekane nenkinga yokuqedwa.

Uma kuqhathaniswa ne-DC Servo Motors, i-Magnent Magnet AC Servo Motors inezinzuzo ezilandelayo ezilandelayo:

I-Brush ne-Commutator, ukuhlinzwa kuthembeke ngokwengeziwe nesondlo.

(2) I-Stator Winding Heating incishiswa kakhulu.

⑶ I-inertia incane, futhi uhlelo lunokuphendula okuhle okusheshayo.

⑷ isivinini esiphakeme nesimo sokusebenza esiphakeme sihle.

Usayizi we-⑸Small nesisindo esikhanyayo ngaphansi kwamandla afanayo.

I-Servo Motor Rustic

Ukwakheka kwesitebhisi se-AC Servo Motor kufana ngokufana nalokho kweCapaCitor Split-Phase Asynchronous motor. I-STAS ifakwe ngama-windings amabili anomehluko we-90 °, eyodwa yi-RF evusa i-RF, exhunywe njalo kwi-ac voltage UF; Enye i-control winding l, exhunywe kwi-control Signal Voltage UC. Ngakho-ke i-AC Servo Motor ibizwa nangokuthi ama-serro motors amabili.

I-rotor yemoto ye-AC Servo motor ivame ukwenziwa ekheji le-squirrel, kodwa ukuze enze i-servo motor ibe nobubanzi besivinini esikhulu, izici zomshini ezihambisanayo, uma i-rotor yokuphendula, uma i-rotor resuration, uma umkhawulo we-rotor mncane futhi umzuzu we-inertia mncane. Njengamanje, kunezinhlobo ezimbili zezakhiwo ze-rotor ezisetshenziswa kabanzi: eyodwa i-rotor ye-squirrel -cage enomhlahlandlela ophakeme - imihlahlandlela yokuthula imigoqo eyenziwe ngezinto zokwakha eziphakeme kakhulu. Ukuze kuncishiswe isikhathi se-inertia ye-rotor, i-rotor yenziwa incane; Enye indebe eyize - i-rotor ebabazekayo eyenziwe nge-aluminium alloy, indebe yodonga ingu-0.2 -0.3mm, i-inertia ye-inertia ye-hollow Conf -Shaper Rotor incane, impendulo iyashesha, ngakho-ke kusetshenziswa kabanzi.

Lapho i-AC Servo motor ingenawo amandla okulawula, kukhona kuphela amandla kazibuthe akhiqizwa yi-exparition winding esitimelweni, futhi i-rotor imile. Lapho kukhona i-control voltage, kwakhiqizwa amandla kazibuthe ajikelezayo esitsheni, futhi i-rotor ijikeleza indlela yamandla kazibuthe ajikelezayo. Lapho umthwalo uhlala njalo, ijubane lezimoto lishintsha ngobukhulu bamandla okulawula. Lapho isigaba se-voltage control siphambene, i-servo motor izobuyiselwa emuva.

Yize umgomo osebenzayo we-AC Servo motor ufana neyaleli Ngakho-ke, uma kuqhathaniswa neCapacitor-asynchronous motor, i-servo motor inezici ezintathu ezibalulekile:

1. I-torque enkulu yokuqalisa: Ngenxa yokumelana okukhulu kwe-rotor, isimilo se-torque (isimo semishini) siseduze ne-linear, futhi sine-torque enkulu yokuqala. Ngakho-ke, lapho i-stator ine-control voltage, i-rotor ijikeleza ngokushesha, okunezimpawu zokuqala nokuzwa okuphezulu.

2. Ububanzi obubanzi bokusebenza: ukusebenza okuzinzile nomsindo ophansi. [/ p] [p = 30, 2, kwesobunxele] 3. Akunasidlali sokuziphendulela

Kuyini "ukuhambisa ukuhambisa kahle okuncane"?

"Ukudluliswa kwe-Precision Micro motor" kungasheshe kukhiphe imiyalo eshintsha njalo ngohlelo, bese ushayela umshini we-servo ukuqedela umsebenzi obekulindelwe yimiyalo, futhi iningi lawo lingahlangabezana nalezi zidingo ezilandelayo:

1. Kungaqala, yeka, ukubopha, ukubopha, ukubuyela emuva bese kugijima ngejubane eliphansi njalo, futhi kunondla okuphezulu kwemishini, izinga eliphakeme lokumelana nokushisa kanye nezinga eliphakeme lokuvimbela kanye nezinga eliphakeme lokufakelwa kanye nezinga eliphakeme lokufakelwa.

2. Ikhono elihle lokuphendula okusheshayo, i-torque enkulu, umzuzu omncane we-inertia kanye nesikhathi esincane njalo.

3. Ngomshayeli kanye nesilawuli (njenge-servo motor, ukuhambisa motor), ukusebenza kwama-control kulungile.

4. Ukwethenjwa okuphezulu nokunemba okuphezulu.

Isigaba, ukwakheka kanye nokwenza kwe-motor "yokuhambisa kahle"
