Izindaba

I-1, Ukuqonda indawo efile, i-hysteresis, ukunemba kokumisa, ukulungiswa kwesignali yokufaka, nokusebenza okumaphakathi ekulawuleni i-servo
Ngenxa ye-oscillation yesignali nezinye izizathu, isignali yokufaka nesignali yempendulo yesistimu ngayinye yokulawula iluphu ayikwazi ukulingana ngokuphelele, okubandakanya inkinga yokulawula indawo efile kanye ne-hysteresis. Isistimu ayikwazi ukuhlukanisa ibanga lomehluko phakathi kwesiginali yokufaka nesignali yempendulo, okuyibanga lezoni efile yokulawula.
Ngenxa ye-oscillation yesignali, ukunemba komshini, nezinye izizathu, isistimu yokulawula okuzenzakalelayo ye-servo ihlale yenza izinguquko ebangeni elincane elingaphandle kwendawo efile yokulawula. Ukuze uvimbele i-servo ekulungiseni i-oscillations ebangeni elincane, umphumela we-hysteresis udinga ukwethulwa.
Indawo efile yokulawula i-hysteresis inkulu uma kuqhathaniswa, enobubanzi bendawo efile yokulawula evamile engu-± 0.4%. Iluphu ye-hysteresis ingasethelwa ku-± 2%.

 

Umehluko phakathi kwesignali yokufaka kanye nesignali yempendulo awubangeli ukuthi injini ihambe ngaphakathi kwe-hysteresis loop. Umehluko phakathi kwesignali yokufaka kanye nesignali yempendulo ingena ku-hysteresis loop, futhi injini iqala ukubhuleka nokuma.
Ukunemba kokumadigcina ukunemba okuphelele kwesistimu ye-servo, njengokulawula indawo efile, ukunemba komshini, ukunemba kwe-potentiometer yempendulo, nokulungiswa kwesignali yokufaka. Ukulungiswa kwesignali okokufaka kubhekisela kububanzi obuncane bokulungiswa kwesistimu ye-servo yesiginali yokufaka, futhi ukulungiswa kwesignali yokufaka ye-servo yedijithali kungcono kakhulu kune-analog servo. Ukusebenza kokubuyisela kuncike ku-hysteresis nokunemba kokuma.

 

 

2. Kungani i-servo ihlale yenza umsindo oklewulayo
I-servo ihlale yenza umsindo wokulungisa wokumisa emuva naphambili, ngoba amanye ama-servo ayawenzaayinawo umsebenzi wokulungisa i-hysteresis, futhi ibanga lendawo efile yokulawula liyalungiswa libe lincane. Uma nje isignali yokufaka nesignali yempendulo ihlala ishintshashintsha, futhi umehluko wabo udlula indawo efile yokulawula, i-servo izothumela isignali ukushayela injini.
Ukwengeza, ngaphandle komsebenzi wokulungiswa kwe-hysteresis, uma ukunemba komshini wesethi yegiya le-servo kungalungile, indawo ebonakalayo yezinyo inkulu, futhi uhla lokujikeleza lwe-potentiometer yempendulo ludlula uhla lwendawo efile yokulawula, i-servo nakanjani izolungisa ngokuqhubekayo futhi iqhume ngokuqhubekayo.

 

3, Kungani amanye ama-servos aqhuma futhi ashise amabhodi wesekethe kalula
Amanye ama-servos asebenzisa amadivaysi kagesi anesimanje esifanayo. Uhlelo ludizayinelwe ngokusebenza kokuvikela okudlulele noma i-chip ifakwe umsebenzi wokuvikela owedlule, ekwazi ukubona isimo esivinjiwe sesekethe yamanje nesifushane futhi imise ngokushesha isignali ye-motor drive. Ukwengeza, i-varistor ingaxhunywa kumjikelezo we-motor ukuvimbela ukugcwala kwesikhashana, futhi i-capacitor edonsayo ingaklanywa ekugcineni kwedivayisi yamandla.Lolu hlobo lwe-servo motor akulula ukulushisaamabhodi esekethe namamotho ngenxa yokuvinjwa kwenjini okubangelwa ukuqhuma. Ayinabo ubudlelwano obuphelele nokuthi i-servo yenziwe ngamazinyo ensimbi noma amazinyo epulasitiki.

4. Kungani i-servo inyakaza
Indawo efile yokulawula iyazwela, futhi amasignali okokufaka kanye nempendulo ashintshashintsha ngenxa yezizathu ezihlukahlukene, okubangela ukuthi umehluko udlule ububanzi kanye nengalo yephini lokuqondisa, okuholela ekunyakazeni kwephini.

 

5, Ukuxilongwa kwephutha okujwayelekile kwe-servo motor
1) Ngemva kokuqhuma, i-servo motor yashwibeka ngendlela exakile, ingalo ye-rocker rocker yayingalawuleki, nengalo ye-rocker yashelela.

Kungaphetha ngokuthi igiya lishaneliwe lashintshwa.
I-2) Ngemva kokuqhuma, ukuvumelana kwe-servo motor kwehle kakhulu. Into eyenzeka ukuthi i-servo motor eyonakele inokuphendula kancane kanye nokushisa okukhulu, kodwa ingasebenza ngemiyalelo yokulawula, kodwa inani le-rudder lincane kakhulu futhi lihamba kancane.

Isiphetho esiyisisekelo: I-servo motor ine-overcurrent. Ngemva kokukhipha injini, kwatholakala ukuthi i-no-load current ye-motor yayikhonaphezulu kakhulu (>150MA), futhi ilahlekelwe ukusebenza kwayo okungaguquki (i-motor eqinile engenawo umthwalo wamanje ≤ 60-90MA). Shintshanisa i-servo motor.
I-3) Ngemva kokuqhuma, kwakungekho impendulo evela ku-servo ngemva kokuguqula i-rudder.
Ukuzimisela okuyisisekelo: Uma isifunda se-elekthronikhi se-servo motor siphukile, othintana naye umpofu, noma ingxenye yokushayela ye-motor noma ibhodi lesekethe ye-servo motor ishisiwe, qala uhlole isekethe, okuhlanganisa ipulaki, i-motor lead, kanye ne-servo motor lead nganoma yisiphi isenzo esivulekile sesekethe. Uma kungenjalo, zisuse ngamunye ngamunye. Okokuqala, susa injini bese uhlola i-no-load current.

 

Uma i-no-load yamanje ingaphansi90MA, kusho ukuthi injini yinhle, futhi inkinga ibangelwa ukusha kwe-servo motor drive. Kukhona ama-patch transistors ama-2 noma ama-4 amancane ebhodini le-9-13g micro servo motor, elingashintshwa. Uma kukhona ama-transistors angu-2, kufanele ashintshwe ngokuqondile nge-Y2 noma i-IY, okungukuthi, i-SS8550. Uma kukhona i-H-bridge circuit enama-transistors amane, ingashintshwa ngokuqondile. Shintsha ngo-2 Y1 (SS8050) no-2 (SS8550) ngokuqondile, UYR we-65MG - sebenzisa i-Y1 (SS8050 IC=1.5A); I-UXR -- Faka esikhundleni ngokuqondile nge-Y2 (SS8550, IC=1.5A).
4) Uma i-servo motor ihluleka, ingalo ye-rocker ingajikeleza kuphela ohlangothini olulodwa futhi ingahambi ngakolunye uhlangothi.
Ukwahlulela: I-servo motor isesimweni esihle. Ukuhlola okuyinhloko kuyingxenye yokushayela. Kungenzeka ukuthi uhlangothi olulodwa lwe-drive transistor lushisiwe. Lilungise ngokwe (3).

 

 

I-5) Ngemva kokulungisa i-servo motor nokuyivula, kwatholakala ukuthi i-servo motor yayinamathele ohlangothini olulodwa futhi yenza umsindo ozwakalayo.
Isiphetho: Kubonisa ukuthi amatheminali amahle nebi we-servo motor noma izintambo zokugcina ze-potentiometer zixhunywe ngokungalungile. Vele uhlehlise isiqondiso sokuxhuma okubili kwenjini.

 
6) Ngemva kokuthenga i-servo motor entsha, ngathola ukuthi yayinyakaza kakhulu lapho ivuliwe, kodwa ngemva kokusebenzisa ingalo yokulawula,konke kwakujwayelekile ku-servo motor.
Isiphetho: Lokhu kukhomba ukuthi iI-servo motor yayihlanganiswe ngendlela engafanelenoma ukunemba kwegiya bekungenele ngesikhathi iphuma efekthri. Leli phutha ngokuvamile lenzeka kuma-servo motors ensimbi. Uma ungafuni ukuzibuyisela noma ukuzishintsha, indlela yokuzixazulula wukukhipha ikhava yangemuva ye-servo motor, uhlukanise i-servo motor egiyeni lokunciphisa i-servo, ucindezele umuthi wamazinyo phakathi kwamagiya, ufake isembozo segiya le-servo, ufake izikulufo ze-gearbox zokunciphisa, ufake ingalo ye-servo rocker, bese uzungeza ngokuphindaphindiwe igiya le-rocker kuze kugijime ingalo yensimbi ukuze ugijime igiya lensimbi umsindo wokungqubuzana uyancipha. Ngemuva kokuhlanza igiya le-servo ngophethiloli, faka uwoyela we-silicone egiyeni bese uhlanganisa i-servo motor ukuxazulula iphutha le-servo motor.

 
7) Kukhona uhlobo lwe-servo engasebenzi kahle olubonisa ukuziphatha okungajwayelekile: lapho inzwa eyirimothi ilawulwa ngokuthuthumela, i-servo inempendulo evamile, kodwa lapho inzwa eyirimothi igxiliswe endaweni ethile, ingalo ye-servo enephutha isasebenza kancane, noma isenzo sengalo siyavilapha futhi siya phambili naphambili.
Ngemva kokulungiswa okuningi, kwatholakala ukuthi inkinga ilele kusibambo sensimbi se-potentiometer, okufanele sinamathele ngokuqinile egiyeni lokugcina le-servo motor. Ayixhunyiwe ngokuqinile egiyeni elikhulu (igiya lokugcina) lengalo ye-servo, futhi iyashelela, okwenzaI-servo motor ayikwazi ukutholakala kahleumyalo wesikhundla okhishwe isilawuli, okuholela kumpendulo engalungile nokusesha okuqhubekayo.

 

Ngemuva kokuxazulula ukuxhumana okuqinile phakathi kwe-potentiometer kanye negiya lengalo ye-rocker, iphutha lingaqedwa. Uma iphutha lisekhona ngemva kokulungiswa ngokwendlela, kungase kube inkinga nge-servo motor noma i-potentiometer, okudingeka ihlaziywe ngokugcwele futhi iphenywe ngayinye ngayinye!

 

8) Uma i-servo enephutha iqhubeka nokuzamazama futhi isusa ukuphazamiseka komsakazo, futhi ingalo yokulawula eguqukayo isanyakaza.
Isiphetho: I-potentiometer iyaguga, yishintshe, noma umane uyilahle njengengxenye eyisipele!

 
I-9) Ngemva kokufaka i-servo ye-digital tilt, kwatholakala ukuthi i-servo yayingasebenzi kahle, ngesivinini esihlukile. Yabuyiselwa kumkhiqizi futhi ngisho nangemva kokuyishintsha ngezintathu, ukungaguquguquki kwakusempofu.
Isiphetho: Kwatholakala kamuva ukuthi amanye ama-servos edijithali adinga i-BEC, futhi ngemva kokufaka i-BEC yangaphandle engu-5. V3A, iphutha laxazululwa, kungakhathaliseki ukuthi ikhwalithi yama-servos.
