Motokari yekufambisa motokari ndeyekutonga kutenderera kwemotokari kana kumira, uye kukurumidza kwekutenderera.Chikamu chekutonga chemotokari chinonziwo electronic speed controller (ESC) .Kugadziriswa kwemagetsi kunoenderana nekushandiswa kwemagetsi akasiyana-siyana, kusanganisira brushless uye brashi kugadzirisa magetsi.
Iyo magineti yekusingaperi yebhurashi-motor inogadziriswa, iyo coil inokuvadzwa yakatenderedza rotor, uye kutungamira kweiyo magnetic field inoshandurwa nekusaenderera mberi kusangana pakati pebhurashi uye commutator kuchengetedza rotor ichitenderera ichienderera.
Brushless mota, sezita rayo rinoratidza, haina inonzi brashi uye commutator. Rotor yaro igineti yekusingaperi, nepo coil yakagadziriswa. Iyo yakabatana zvakananga kune kunze kwesimba rekupa.
Muchokwadi, iyo brushless mota inodawo gavhuna wemagetsi, inova mota dhiraivha. Inoshandura kutungamira kwezvino mukati meiyo yakagadziriswa coil chero nguva, kuitira kuti ive nechokwadi chekuti simba riri pakati payo negineti risingaperi rinopesana uye kutenderera kunoenderera kunogona kuenderera.
Brushless mota inogona kushanda pasina kudikanwa kwekugadzirisa magetsi, yakananga kupihwa kwemagetsi kumota inogona kushanda, asi izvi hazvigone kudzora mota kumhanya.Brushless mota inofanirwa kuve nemagetsi ekugadzirisa, kana haigone kutenderera.Direct ikozvino inofanira kushandurwa kuita matatu - phase alternating current by brushless current regulation.
Kugadziriswa kwemagetsi kwekutanga hakuna kufanana nekugadziriswa kwemagetsi ikozvino, kwekutanga ndeye brashi magetsi ekugadzirisa, akati izvi iwe ungada kubvunza, chii chinonzi brashi magetsi kugadzirisa, uye ikozvino brushless magetsi ekugadzirisa ane musiyano upi.
Muchokwadi, pane musiyano mukuru pakati peiyo brushless uye iyo brushless yakavakirwa pamota. Iye zvino rotor yemotokari, iyo iyo chikamu chinogona kutenderera, ndiyo yose magnet block, uye coil ndiyo stator isingatendereri, nokuti hapana carbon brush pakati, iyi ndiyo brushless motor.
Uye mota yebhurashi, sekureva kunoita zita ibhurashi kabhoni, saka kune mota yebhurashi, senge isu kazhinji vana vanotamba neremote control yemota ibhurashi mota.
Maererano nemhando mbiri dzemagetsi emagetsi uye zita rebhurashi uye bhurashi - regulation yemagetsi yakasununguka.Kubva kune imwe nyanzvi yekuona ibhurashi ndiyo inobuda yakananga ikozvino, brushless simba rinobuda ndiro nhatu-phase ac.
Yakananga ikozvino magetsi akachengetwa mubhatiri yedu, iyo inogona kukamurwa kuva matanda akanaka uye akaipa. Magetsi emhuri yedu 220V, anoshandiswa kuchaja nharembozha kana komputa, ndeye ac.Ac ine imwe frequency, kazhinji kutaura ndeye mutsara wekuwedzera uye minus, plus uye minus nekudzoka nekudzoka; Yakananga ikozvino yakanaka. danda nedanda risina kunaka.
Iye zvino ac nedc zvave pachena, chii chinonzi three-phase magetsi?Maererano nedzidziso, three-phase alternating current is a transmission form of magetsi, anonzi matatu-phase magetsi, ayo anoumbwa neatatu alternating potential with the same. frequency, iyo yakafanana amplitude uye mutsauko wechikamu che120 madhigirii zvakatevedzana.
Kazhinji kutaura, imhuri yedu matatu alternating ikozvino, kuwedzera kune voltage, frequency, drive Angle yakasiyana, mamwe akafanana, ikozvino kune matatu-phase magetsi uye yakananga ikozvino inonzwisiswa.
Brushless, iyo inopinza yakananga ikozvino, kuburikidza nesefa capacitor kudzikamisa voltage.Zvese zvakakamurwa kuva mugwagwa maviri, nzira yese inodzorwa nemagetsi BEC kushandiswa, BEC ndeyekugamuchira uye yemagetsi inodzorwa MCU inoshandiswa mumagetsi, iyo inobuda kusvika inogamuchira tambo yemagetsi ndiyo mitsara mitsvuku pamutsara uye mutsara wakasviba, imwe yacho inobatanidzwa muMOS tube kushandisa nzira yose, pano, magetsi anodzorwa nemagetsi, SCM yakatanga, kutyaira MOS. pombi vibration, ita madonhwe emota achidonha ruzha.
Zvimwe zvigadziriso zvemagetsi zvine throttle calibration function. Usati wapinda mugadziriro yekumira, inotarisisa kana iyo throttle nzvimbo yakakwira kana yakaderera kana pakati. Kana iyo throttle nzvimbo yakakwira, inozopinda mukuyerwa kwemagetsi ekugadzirisa rwendo.
Kana zvese zvagadzirira, iyo single-chip microcomputer mukugadziriswa kwemagetsi ichasarudza kubuda kwemagetsi uye frequency pamwe negwara rekutyaira uye yekuisa Angle kutyaira mota kumhanya uye kutendeuka zvinoenderana nechiratidzo paPWM chiratidzo mutsara. brushless electromodulation musimboti.
Kana mota yedhiraivha ichimhanya, mapoka matatu eMOS chubhu anoshanda mukati memagetsi modulation, maviri muboka rega rega, iyo yakanaka inobuda inodzora, yekudzora yakashata kubuda, kana kubuda kwakanaka, kuburitsa kwakashata, kwete kushata, kubuda kwe iyo inobuda yakanyanya, yakagadzira ikozvino inoshandura, zvakare, kuita basa iri, mapoka matatu ehuwandu hwavo ndeye 8000 hz.Kutaura izvi, brushless magetsi regulation zvakare yakaenzana nefekitari injini inoshandiswa pahuwandu. mushanduri kana gavhuna.
Iyo inopinza ndeye dc, kazhinji inofambiswa ne lithium mabhatiri.Kubuda kwechitatu-phase ac, iyo inogona kutyaira mota zvakananga.
Mukuwedzera, iyo airmodel brushless electronic governor inewo mitsetse mitatu yekuisa zviratidzo, kuisa PWM chiratidzo, inoshandiswa kudzora kumhanya kwemota.
Saka sei iwe uchida kwakakosha tuning yemagetsi pane iyo quad, chii chakakosha pazviri?
Iyo quad ine OARS ina, uye maviri OARS ane crisscross.Kutenderera mberi uye reverse kutenderera pane chidhiraivho chechairi chinogona kugadzirisa matambudziko ekutenderera anokonzerwa nekutenderera kweblade imwe.
The dhayamita yegwara rega rega idiki, uye simba repakati rinopararira sezvo mana OARS anotenderera.Kusiyana negwaza rakatwasuka, pane chete inertial centrifugal simba rinoburitsa concentrated centrifugal force inoumba gyroscopic property, kuchengetedza fuselage kuti isapinduka. nokukurumidza.
Naizvozvo, kuwanda kwekuvandudzwa kweyekutungamirira giya rekudzora chiratidzo yakaderera kwazvo.
Axis ina kuitira kukurumidza kupindura, mukupindura shanduko yepostural inokonzerwa nekudonha, inoda kumhanya kwemagetsi kuchinjika, kumhanya kwekuvandudza kweyakajairwa PPM yemagetsi inodzorwa chete ne50 hz, haigutse chinodiwa chinodzora kumhanya, uye PPM yemagetsi. kudzora MCU yakavakirwa-muPID, inogona kukurumidza kushandura maitiro eyakajairwa modhi ndege kuti ipe yakatsetseka, pane ina axis haina kukodzera, ina axis mota yekumhanyisa shanduko inodiwa kukurumidza kuita.
Nekumhanya kwakanyanya kwakakosha kugadzirisa magetsi, IIC bhazi interface transmission control chiratidzo, inogona kuwana mazana ezviuru zvemotor kumhanya shanduko pasekondi imwe, muine-axis kubhururuka, nguva yemafungiro inogona kuchengetedzwa yakagadzikana.Kunyangwe nekukasira kwemasimba ekunze, zvichiri intact.
