1. Fahimtar matattu zone, hysteresis, sakawa daidaito, shigar da siginar ƙuduri, da kuma tsakiya yi a servo iko.
Saboda motsin sigina da wasu dalilai, siginar shigarwa da siginar martani na kowane tsarin kula da rufaffiyar madauki ba zai iya zama daidai ba gaba ɗaya, wanda ya haɗa da matsalar kula da matattu yankin da jijiyoyi. Tsarin ba zai iya bambanta kewayon bambanci tsakanin siginar shigarwa da siginar amsawa, wanda shine kewayon yanki mai mutuƙar sarrafawa.
Saboda siginar oscillation, daidaito na inji, da sauran dalilai, tsarin sarrafawa ta atomatik na servo koyaushe yana yin gyare-gyare a cikin ƙaramin kewayo a waje da mataccen yankin sarrafawa. Don hana servo daga daidaitawa zuwa oscillations a cikin ƙaramin kewayon, ana buƙatar gabatar da tasirin hysteresis.
Mataccen yanki mai kula da hysteresis yana da girma sosai, tare da mataccen yanki na sarrafawa na gaba ɗaya na ± 0.4%. Za a iya saita madauki na hysteresis zuwa ± 2%.

 

Bambanci tsakanin siginar shigarwa da siginar amsawa baya haifar da motsi a cikin madauki na hysteresis. Bambanci tsakanin siginar shigarwa da siginar amsawa yana shiga madauki na hysteresis, kuma motar ta fara birki da tsayawa.
Daidaiton sanyawadya dogara da cikakken daidaiton tsarin servo, kamar yankin mataccen sarrafawa, daidaiton injina, daidaiton potentiometer martani, da ƙudurin siginar shigarwa. Ƙirar siginar shigarwa tana nufin mafi ƙarancin ƙuduri na tsarin servo don siginar shigarwa, kuma ƙudurin siginar shigarwa na servo na dijital ya fi na analog servo. Ayyukan dawowar ya dogara ne akan ƙwanƙwasa da daidaiton matsayi.

 

 

2. Me yasa servo koyaushe yana yin sauti mai tsauri
Sabis ɗin yana yin sautin daidaitawa da baya da baya, saboda wasu servos suna yiba su da aikin daidaitawar hysteresis, kuma ana daidaita kewayon mataccen yanki mai sarrafawa don zama ƙarami. Muddin siginar shigarwa da siginar amsawa koyaushe suna canzawa, kuma bambance-bambancen su ya wuce yankin mataccen sarrafawa, servo zai aika sigina don fitar da motar.
Bugu da ƙari, ba tare da aikin daidaitawa na hysteresis ba, idan daidaiton inji na saitin kayan aikin servo ba shi da kyau, matsayi mai kama da haƙori yana da girma, kuma kewayon jujjuyawar ra'ayi na potentiometer ya wuce kewayon mataccen yanki na sarrafawa, servo ba makawa zai daidaita ci gaba kuma yana ƙuƙuwa.

 

3. Me yasa wasu servos ke fashewa da ƙone allunan da'ira cikin sauƙi
Wasu servos suna amfani da na'urorin wuta tare da halin yanzu iri ɗaya. An tsara tsarin tare da aikin kariya mai wuce gona da iri ko kuma guntu yana sanye da aikin kariya mai wuce gona da iri, wanda zai iya gano katange matsayi na yanzu da gajeriyar kewayawa kuma da sauri ya dakatar da siginar tuƙi. Bugu da ƙari, ana iya haɗa varistor zuwa da'irar motar don hana wuce gona da iri na ɗan lokaci, kuma ana iya ƙirƙira capacitor mai ɗaukar nauyi a ƙarshen na'urar wutar lantarki.Irin wannan motar servo ba ta da sauƙi don ƙonewaallunan kewayawa da injina saboda toshewar injin da fashewa ya haifar. Ba shi da cikakkiyar alaƙa da ko an yi servo da haƙoran ƙarfe ko haƙoran filastik.

4. Me yasa servo ke girgiza
Mataccen yankin sarrafawa yana da hankali, da shigarwar da siginar amsawa suna canzawa saboda dalilai daban-daban, yana haifar da bambanci ya wuce iyaka da hannun rudder don motsawa, yana haifar da girgiza rudder.

 

5. Janar kuskure ganewar asali na servo motor
1) Bayan fashewar, motar servo ta yi birgima sosai, ba a kula da sitiyarin roka ba, kuma hannun roka ya zame.

Ana iya ƙarasa da cewa an share kayan kuma an maye gurbinsu.
2) Bayan fashewar, daidaiton motar servo ya ragu sosai. Abin mamaki shine cewa motar servo mai lalacewa yana da jinkirin amsawa da zafi mai tsanani, amma yana iya gudana tare da umarnin sarrafawa, amma adadin rudder yana da ƙananan kuma jinkirin.

Ƙarshe na asali: Motar servo tana da wuce gona da iri. Bayan cire motar, an gano cewa babu kayan aiki na motarmai girma (> 150MA), kuma ya rasa ingantaccen aikin sa (daidaitaccen injin babu-load na yanzu ≤ 60-90MA). Sauya motar servo.
3) Bayan fashewar, babu amsa daga servo bayan kunna rudder.
Ƙididdiga ta asali: Idan na'urar lantarki ta servo motor ta karye, lambar sadarwar ba ta da kyau, ko kuma ɓangaren tuƙi na motar ko allon kewayawa na servo motor ya ƙone, da farko duba da'irar, ciki har da filogi, gubar mota, da servo motor gubar ga kowane buɗaɗɗen yanayi. Idan ba haka ba, kawar da su daya bayan daya. Da farko, cire motar kuma gwada halin yanzu ba-load.

 

Idan babu kaya a halin yanzu ya gaza90MA, yana nufin motar tana da kyau, kuma matsalar tabbas tana faruwa ne sakamakon konawar motar servo. Akwai ƙananan transistor guda 2 ko 4 akan allon kewayawa na 9-13g micro servo, wanda za'a iya maye gurbinsa. Idan akwai transistor guda 2, dole ne a maye gurbinsu kai tsaye da Y2 ko IY, wato SS8550. Idan akwai da'irar H-bridge mai transistor hudu, ana iya maye gurbinsa kai tsaye. Sauya da 2 Y1 (SS8050) da 2 (SS8550) kai tsaye, UYR na 65MG - yi amfani da Y1 (SS8050 IC=1.5A); UXR - Sauya kai tsaye da Y2 (SS8550, IC=1.5A).
4) Idan servo motor kasa, rocker hannu iya kawai juya a gefe daya kuma ba motsi a daya gefen.
Hukunci: Motar servo yana cikin yanayi mai kyau. Babban dubawa yana kan ɓangaren tuƙi. Mai yiyuwa ne an kona daya gefen na’urar transistor. Gyara shi bisa ga (3).

 

 

5) Bayan an gyara mashin din servo da kunna shi, sai aka ga motar ta makale a waje guda sai ta yi wata kara.
Kammalawa: Yana nuna cewa madaidaicin madaidaicin madaidaicin madaidaicin servo motor ko wayoyi masu ƙarfi na potentiometer an haɗa ba daidai ba. Kawai juya alkiblar haɗin gwiwar motar guda biyu.

 
6) Bayan siyan sabon motar servo, na gano cewa yana girgiza sosai lokacin da aka kunna shi, amma bayan amfani da hannun sarrafawa,komai ya kasance al'ada ga servo motor.
Kammalawa: Wannan yana nuna cewaservo motor an haɗa shi ba daidai bako daidaiton kayan aikin bai isa ba lokacin da ya bar masana'anta. Wannan laifin yawanci yana faruwa akan injinan servo na ƙarfe. Idan ba kwa son komawa ko maye gurbinsu, hanyar magance kai ita ce cire murfin baya na servo motor, raba motar servo daga kayan rage servo, matse wasu man goge baki tsakanin kayan aikin, sanya murfin gear ɗin servo, saka screws na gearbox, shigar da servo rocker hannu, kuma akai-akai jujjuya da hannu don yin amfani da ginshiƙi da hannu har sai da gear gear ɗin. an rage hayaniyar gogayya ta gear. Bayan tsaftace kayan aikin servo tare da man fetur, sanya man siliki a kan kayan kuma hada servo motor don magance matsalar motar servo.

 
7) Akwai nau'in servo mara aiki wanda ke nuna halayen ban mamaki: lokacin da aka sarrafa nesa ta hanyar girgiza, servo yana da amsa ta al'ada, amma lokacin da aka saita nesa nesa zuwa wani matsayi, hannun servo mara kyau har yanzu yana gudana a hankali, ko aikin hannu yana sluggish yana motsawa baya da gaba.
Bayan gyare-gyare da yawa, an gano cewa matsalar ta ta'allaka ne a cikin hannun karfe na potentiometer, wanda ya kamata a makale a cikin kayan aiki na karshe na servo motor. Ba a haɗa ta sosai da babban kayan aiki (gear na ƙarshe) na hannun servo, har ma da zamewa, yana haifar daservo motor don kasa gano daidai wuriumarnin matsayi da aka bayar ta hanyar sarrafawa, yana haifar da ra'ayi mara kyau da ci gaba da bincike.

 

Bayan warware maƙarƙashiyar haɗin kai tsakanin potentiometer da kayan aikin rocker, za a iya kawar da laifin. Idan har yanzu laifin yana wanzu bayan gyara bisa ga hanyar, yana iya zama matsala tare da motar servo ko potentiometer, wanda ke buƙatar bincika gabaɗaya kuma bincika ɗaya bayan ɗaya!

 

8) Idan servo mara kyau ya ci gaba da girgiza da kawar da tsangwama na rediyo, kuma hannun mai ƙarfi yana girgiza.
Kammalawa: Potentiometer yana tsufa, maye gurbinsa, ko kuma kawai a goge shi azaman kayan gyara!

 
9) Bayan shigar da servo na dijital tilt servo, an gano cewa servo ba ya aiki yadda yakamata, tare da saurin gudu. An mayar da shi ga masana'anta kuma ko da bayan maye gurbin shi da uku, daidaito ya kasance mara kyau.
Ƙarshe: Daga baya an gano cewa wasu servos na dijital suna buƙatar BEC, kuma bayan shigar da BEC na waje na 5. V3A, an warware matsalar, ba tare da la'akari da ingancin servos ba.
