Modelling servos kune asiri-standard mabasa

Vazhinji vevaverengi vemazuva ano vangangove havayeuki zvakapfuura, apo iyo yakapfava yakaenzana servo kune modhi yaiwanzova kurota kunoitika kune vese vechidiki mamodeli. Ipapo zviito zvandinoda kuratidza pano nhasi zvinogona kutariswa - kana zvisiri kumhura, saka hupenzi?

Asi nguva (nemitengo yemasevhisi) yachinja zvakanyanya. Nhasi, servos haingoshandiswi chete kushandura nzvimbo yezvidzoreso kana throttle yemhando injini. Chikurusa? Munguva ichangopfuura, marobhoti akave marobhoti, kunyange makadhibhodi modellers anewo mugove wavo mairi (ona yapfuura chinyorwa che "Young Technician").

Muna December?Mumusangano? takanga tichivaka kadhibhodhi modhi yechitima, iyo iyo chitima chemakadhibhodi chakafambawo nemagineti, nekuda kwe servo yakagadziridzwa. Muchikamu chino, ini ndichakupa maviri mabikirwo ekushandura servo kuita inoenderera inofamba - yezvikumbiro zvakadaro, kusanganisira.

Chii servo?

Kukushandirai nesu? iwe unogona kutaura, asi mu labyrinth yemabhokisi pamasherufu ezvitoro zvefashoni unogona kurasika? Zvakakodzera kudzidza zvakakosha zvezvirongwa izvi zvinobatsira.

Chaizvoizvo, modelling servos dzakakamurwa kuita:

• micro (kusvika 10 g);
• mini (kusvika 20g),
• mwero (kusvika 50 g);
• hombe (> 50 g - semuenzaniso, kune chinosekesa chassis).

Munguva pfupi yapfuura, kupatsanurwa nerudzi rwemanejimendi kwave kuonekawo zvakajeka:

• analog (kusvika parizvino inonyanya kufarirwa, yakachipa, ine yakaderera simba rekushandisa),
• dhijitari (chaizvoizvo, paine mukana wekugadzira imwe nzvimbo isina kwayakarerekera, asi kazhinji inodhura zvakanyanya - ndosaka isingawanzo shandiswa sedhiraivha mota).

Mamwe ma servo paramita anoenderana nechinangwa chedu:

• yakanyanya torque (zvinoreva kuwanda mu kg iyo servo inokwanisa kusimudza padanda 1 cm kureba)
• angular velocity
• kushandiswa kwazvino (mu mA - ruzivo runobatsira patinenge tichizoshandisa servos ine shoma BEC system - dzimwe nguva tinongove ne1-1,5A max)

Maservos anofambiswa newaya mbiri (tsvuku kana orenji kusvika (+), dema kana brown (-) uye pulse-inodzorwa kune yero waya.

Paunosarudza servo kutyaira robhoti, breadboard kana chero imwe modhi, unofanira kunyatsotarisa torque yayo, zviyero, uye hongu? Ndinotenda. Dzimwe nguva tinogona kuwana zvakachipa, semuenzaniso, servo yakakuvadzwa zvishoma (muchina kana magetsi), iyo, zvichienderana nezvatinoda, inogonawo kuva yakanaka. Parizvino, microserva itsva (kureva inorema anenge 8

magiramu) anogona kutotengwa mukati megumi zł pachidimbu (kazhinji mune anonzi akawanda-packs). Yakasimba chiyero saizi servos uye zvechokwadi kuwedzera kwakawanda kunogona kuwanikwa kweinosvika makumi maviri zł.

Zvigadzirwa kubva kumakambani asingazivikanwe kazhinji zvakachipa pane zvigadzirwa zvemhando ine maparamendi akafanana, uye akakodzera kutarisa mazviri. Pakati pevagadziri vemarobhoti, nzira dzakajairwa dzakadai seSG-5010 (inotakura ine torque ye 6,5 kgcm) uye MG-995 (ine magiya esimbi ane kaviri kusunda) anonyanya kufarirwa. Kubva pamhuno? zvinonyanyozivikanwa ndezve MG-90 (1,6 kgcm) uye MG-09 (1,8 kgcm, ine magiya esimbi). Kunyangwe iyo musimboti wekugadzirisa microservers wakafanana? Izvi, zvisinei, nekuda kwekurongedza kukuru uye matambudziko anoenderana? vanonyanya kuoma kushanda navo. Nezvinangwa zvechinyorwa chino, ndasarudza kuenda neyakanyanya kufarirwa SG-5010 kufamba.

Pane murwere - inguva yekuvhiyiwa

Tisati tatanga, zvakakosha kuti tifunge kana isu tine hanya nedhiraivha pachayo (motor + giya + kesi) kana isu tinoda kudzora zvakaenzanirana kumhanya kweiyo servo yakashandurwa tichishandisa RC transmitter kana komputa kana handheld servo controller.

Kupindira kushoma kunoda gadziriso inoshandura chete controlled tiller movement kuti ienderere mberi. Muchiitiko ichi, isu tichaedza chete kuvhara potentiometer munzvimbo yepakati, pasinei nechinzvimbo che t-bar. Kana nekuda kwezvikonzero zvakasiyana-siyana izvi zvisingakwanisi kana kuti isu hatidi kuita izvi, iyo potentiometer inotsiviwa neaviri akanyatsosarudzwa resistors. Dzimwe nguva magetsi anotorwawo kunze kwenyaya, izvo zvinobvumira kugadziridzwa kunokwanisika kwekuruboshwe potentiometer (zvinosuruvarisa, nzira dzakagadziridzwa hadzidi kugara dzakabata kwazvakarerekera, izvo zvinowanzofanira kugadziriswa kana neinogadzirisa mumudziyo, kana ne. potentiometer ine servos. Mune zvimwe zviitiko (kunyanya mu microdrives) zvakakosha kutsiva potentiometer neaviri akafanana resistors ane kupikisa kwese kwakaenzana ne potentiometer.

Muchiitiko chechipiri? apo isu tinonyanya kufarira giya mota - zvese zvemagetsi zvinobuda mu servo housing? dhiraivha pachayo inoramba iripo. Muchiitiko ichi, kupindira kwekuwedzera kunowanzodiwa, uyezve injini itsva yekumhanyisa controller.

Ruzivo rwemhando mbiri dzemashandiro anotsanangurwa pasi pezviverengero zvinotevera.

Ko maservos akashandurwa nenzira iyi ane zviuru zvekushandisa? zvakaoma kuzvinyora pano kunyange muchidimbu. Une chokwadi here kuti unogona kuwana matsva zvakare? Ndinovimba kuti vaverengi vachazviwanira zvavo. Ndiri kutarisira izvozvo, pamwe chete nezvakatumirwa paYoung Technician internet forum. Ndokuona!
