Kudzora mota kunoreva kudzora kutenderera kana kumira kwemota, uye kumhanya kwekutenderera. Chikamu chekudzora mota chinonziwo electronic speed controller (ESC). Kugadzirisa magetsi kunoenderana nekushandiswa kwemamota akasiyana, kusanganisira kugadzirisa magetsi asina mabhurashi nemabhurashi.
Magineti inogara iripo yemota yebhurashi yakasimbiswa, coil inotenderedzwa nerotor, uye kutungamira kwesimba remagineti kunochinjwa nekubatana kusingachinji pakati pebhurashi necommutator kuti rotor irambe ichitenderera nguva dzese.
Mota isina mabhurashi, sezvinoreva zita rayo, haina chinonzi bhurashi ne commutator. Rotor yayo imagneti inogara iripo, ukuwo coil yacho yakagadzika. Yakabatana zvakananga nemagetsi ekunze.
Kutaura zvazviri, mota isina brush inodawo electronic governor, inova mota inofambisa. Inoshandura divi remagetsi ari mukati me fixed coil chero nguva, kuitira kuti simba riri pakati payo ne permanent magnet rirambe richidzongonyedza uye kuti kutenderera kunoramba kuchienderera mberi.
Mota isina brush inogona kushanda pasina chikonzero chekugadzirisa magetsi, kupa magetsi zvakananga kumota kunogona kushanda, asi izvi hazvigone kudzora kumhanya kwemota. Mota isina brush inofanira kugadziriswa nemagetsi, kana kuti haigone kutenderera. Direct current inofanira kushandurwa kuita three-phase alternating current ne brushless current regulation.
Kugadziriswa kwemagetsi kwekutanga hakuna kufanana nekugadzirwa kwemagetsi kuripo iye zvino, kwekutanga ndiko kugadziriswa kwemagetsi ebhurashi, wati izvi ungangoda kubvunza, chii chinonzi kugadziriswa kwemagetsi ebhurashi, uye ikozvino kugadziriswa kwemagetsi kusina bhurashi kune musiyano upi.
Kutaura zvazviri, pane musiyano mukuru pakati pe brushless ne brushless zvakavakirwa pamota. Iye zvino rotor yemota, inova ndiyo inogona kutenderera, ndiyo magnet block yese, uye coil ndiyo stator isingatenderere, nekuti hapana carbon brush pakati, iyi ndiyo brushless motor.
Uye mota yebhurashi, sezvinoreva zita racho, ibhurashi rekabhoni, saka kune mota yebhurashi, sezvatinowanzo tamba nevana neremote control yemota iri mota yebhurashi.
Zvichienderana nemhando mbiri dzemichina yemagetsi uye zita rebhurashi nebhurashi - mutemo wemagetsi usina kusununguka. Kubva pakuona kwenyanzvi, bhurashi inoburitsa magetsi akananga, simba remagetsi risina brush rine maawa matatu.
Direct current imagetsi anochengetwa mubhatiri redu, ayo anogona kukamurwa kuita mapango akanaka neasina kunaka. Simba remhuri yedu re220V, rinoshandiswa pakuchaja nharembozha kana komputa, iac.Ac ine frequency yakati, kazhinji mutsetse we plus ne minus, plus ne minus kuchinjana kumashure nekunze; Direct current ipango rakanaka nepango rakanaka.
Zvino zvaave pachena kuti ac nedc, chii chinonzi magetsi ane zvikamu zvitatu? Zvichienderana nedzidziso, magetsi alternating ane zvikamu zvitatu imhando yemagetsi inotumirwa, inonzi magetsi ane zvikamu zvitatu, ayo anoumbwa nemagetsi matatu anochinjana ane frequency yakafanana, amplitude yakafanana uye musiyano wezvikamu we120 degrees zvichiteerana.
Kazhinji, ndiyo imba yedu matatu alternating current, kuwedzera kune voltage, frequency, drive Angle yakasiyana, mamwe akafanana, ikozvino kune matatu-phase magetsi uye yakananga current zvinonzwisiswa.
Pasina brush, chinhu chinopinzwa chinobuda nemagetsi akananga, kuburikidza ne filter capacitor kuti voltage igare yakasimba. Zvese zviri zviviri zvinopatsanurwa kuita nzira mbiri, nzira yese inoshandiswa nemagetsi neBEC, BEC ndeye receiver nemagetsi neMCU inoshandiswa mumagetsi, chinobuda chinoenda kune receiver yetambo yemagetsi mitsetse mitsvuku pamutsetse nemutsetse mutema, imwe iri mu MOS tube kuti ishandiswe nzira yese, pano, magetsi anodzorwa nemagetsi, SCM yakatanga, kutyaira MOS pipe vibration, kuita kuti madonhwe emota adonhe.
Mamwe magadzirirwo emagetsi ane basa rekugadzirisa throttle. Isati yapinda mu standby system, inoongorora kana nzvimbo ye throttle yakakwira kana kuti yakaderera kana kuti iri pakati. Kana nzvimbo ye throttle yakakwira, inozopinda mu calibration yerwendo rwekugadzirisa electromagnetic.
Kana zvese zvagadzirwa, komputa ine chip imwe chete iri mumagetsi ichasarudza voltage inobuda uye frequency pamwe nekutungamira kwekutyaira uye Angle yekupinda kuti ifambise kumhanya kwemota uye kutendeuka zvichienderana nechiratidzo chiri pamutsetse wechiratidzo wePWM. Uyu ndiwo musimboti we electromodulation isina brushless.
Kana mota yekutyaira ichishanda, mapoka matatu eMOS tube anoshanda mukati memagetsi, maviri muboka rega rega, positive output a control, control negative output, kana positive output, negative output, kwete negative, output ye output iri pamusoro, yakagadzira alternating current, zvakare, kuti iite basa iri, mapoka matatu efrequency yavo i8000 hz. Tichitaura nezveizvi, brushless electrical regulation yakaenzanawo nemota yefekitori inoshandiswa pa frequency converter kana governor.
Chinopinzwa idc, chinowanzo shandiswa nemabhatiri e lithium. Chinobuda i three-phase ac, iyo inogona kutyaira mota zvakananga.
Pamusoro pezvo, airmodel isina mabhurashi emagetsi governor inewo mitsara mitatu yekuisa masaini, chiratidzo chePWM chekupinda, chinoshandiswa kudzora kumhanya kwemota. Kune maaeromodel, kunyanya kune maaeromodel ane axis ina, maaeromodel akakosha anodiwa nekuda kwekusiyana kwawo.
Saka sei uchida kugadziriswa kwemagetsi kwakakosha paquad, chii chakakosha pairi?
Chikwata chine maOARS mana, uye maOARS maviri akapatsanurwa zvakanyanya. Kutenderera mberi uye kutenderera shure padhiraivha yemuchina zvinogona kugadzirisa matambudziko ekutenderera anokonzerwa nekutenderera kwebanga rimwe chete.
Dhayamita yegwara rega rega idiki, uye simba repakati rinopararira sezvo maOARS mana achitenderera. Kusiyana nepaddle yakatwasuka, kune simba rimwe chete repakati rinogadzira simba repakati rinoumba chimiro chegyroscopic, zvichiita kuti fuselage isatenderere nekukurumidza.
Saka, kuwanda kwekuvandudzwa kwechiratidzo chekudzora giya rekufambisa kwakaderera zvikuru.
Ma axis mana kuti apindure nekukurumidza, nekuda kwekuchinja kwechimiro kunokonzerwa nekudzungaira, anoda kugadziriswa kwemagetsi ekumhanya kwepamusoro, kumhanya kwekuvandudza kwePPM yemagetsi inodzorwa nemagetsi inosvika 50 hz chete, haigutse zvinodiwa zvinodzora kumhanya, uye PPM yemagetsi yekudzora MCU yakavakirwa mukati mePID, inogona kushandura hunhu hwendege yemuenzaniso wekare kuti ipe yakapfava, pa axis ina hazvina kukodzera, kuchinja kumhanya kwemota yemagetsi inokwana axis ina inokurumidza kuita.
Nekugadzirisa kwemagetsi kwakakosha kwekumhanya kwakanyanya, chiratidzo chekudzora kutumirwa kwemabhazi eIIC, chinogona kuwana mazana ezviuru ekuchinja kwemota pasekondi, mukubhururuka kwe-axis ina, nguva yekutarisa inogona kuramba yakagadzikana. Kunyangwe nekukasira kwemasimba ekunze, ichiripo.
