Umgaqo wolawulo lwemoto engenabhrashi

Ulawulo lwe-motor drive kukulawula ukujikeleza okanye ukuma kwe-motor, kunye nesantya sokujikeleza. Icandelo lolawulo lwe-motor drive likwabizwa ngokuba yi-electronic speed controller (ESC). Uhlengahlengiso lombane oluhambelana nokusetyenziswa kwee-motor ezahlukeneyo, kubandakanya ukulungiswa kombane okungenabhrashi kunye nebrashi.

Imagnethi esisigxina ye-brush-motor izinzile, ikhoyili ijikelezwe yi-rotor, kwaye ulwalathiso lwe-magnetic field lutshintshwa kukudibana okungaguqukiyo phakathi kwebrashi kunye ne-commutator ukugcina i-rotor ijikeleza rhoqo.

Injini engenabhrashi, njengoko igama layo lisitsho, ayinayo into ebizwa ngokuba yi-brush kunye ne-commutator. I-rotor yayo yimagnethi esisigxina, ngelixa i-coil izinzile. Iqhagamshelwe ngqo kumbane wangaphandle.

Enyanisweni, i-motor engenamabhrashi ikwafuna i-electronic governor, ngokuyintloko eyi-motor drive. Itshintsha indlela yamandla angaphakathi kwi-fixed coil nangaliphi na ixesha, ukuze kuqinisekiswe ukuba amandla aphakathi kwayo kunye ne-magnet esisigxina ayaphazamisana kwaye ukujikeleza okuqhubekayo kunokuqhubeka.

Imoto engenabhrashi ingasebenza ngaphandle kwesidingo sokulungiswa kombane, ukunikezelwa kombane ngqo kwimoto kungasebenza, kodwa oku akunakulawula isantya semoto. Imoto engenabhrashi kufuneka ilungiswe ngombane, okanye ayinakujika. Umbane othe ngqo kufuneka uguqulwe ube ngumbane otshintshanayo wesigaba sesithathu ngommiselo wombane ongenabhrashi.

Ulungiso lombane lokuqala alufani nolungiso lombane lwangoku, olokuqala lulungiso lombane webhrashi, uthe oku ungathanda ukukubuza, yintoni utshintsho lombane webhrashi, kwaye ngoku utshintsho lombane olungenabhrashi lunomahluko onjani.

Enyanisweni, kukho umahluko omkhulu phakathi kwe-brushless kunye ne-brushless ezisekelwe kwi-motor. Ngoku i-rotor ye-motor, eyinxalenye ekwaziyo ukujikeleza, yi-magnet block yonke, kwaye i-coil yi-stator engajikeleziyo, kuba akukho brashi yekhabhoni embindini, le yi-brushless motor.

Kwaye i-brush motor, njengoko igama lisitsho, yi-carbon brush, ngoko ke kukho i-brush motor, njengoko sidla ngokudlala nabantwana nge-remote control ye-motor yi-brush motor.

Ngokweentlobo ezimbini zoomatshini bombane kunye negama lebrashi kunye nebrashi - ummiselo wombane okhululekileyo. Ngokwembono yobungcali, ibrashi yimveliso yombane othe ngqo, umbane ongenabhrashi yi-ac yesigaba sesithathu.

Umbane othe ngqo ngumbane ogcinwe kwibhetri yethu, onokwahlulwahlulwa ube ziipali ezilungileyo nezingalunganga. Umbane wekhaya lethu i-220V, osetyenziselwa itshaja yefowuni okanye ikhompyutha, yi-ac. Umbane we-Ac unamaza athile, ngokubanzi ngumgca wotshintshiselwano lwe-plus kunye ne-minus, i-plus kunye ne-minus; Umbane othe ngqo yipali elungileyo kunye nepali engalunganga.

Ngoku ekubeni i-ac kunye ne-dc zicacile, yintoni umbane wesigaba sesithathu? Ngokwethiyori, umsinga otshintshanayo wesigaba sesithathu luhlobo lombane oludluliselwayo, olubizwa ngokuba ngumbane wesigaba sesithathu, owenziwe ngamandla amathathu atshintshanayo ane-frequency efanayo, ubukhulu obufanayo kunye nomahluko wesigaba se-120 degrees ngokulandelelana.

Ngokubanzi, yindlu yethu emithathu etshintshanayo, ukongeza kwi-voltage, i-frequency, i-drive Angle yahlukile, ezinye ziyafana, ngoku kuqondwa umbane wesigaba sesithathu kunye nomsinga othe ngqo.

Ingenabhrashi, igalelo lisebenza ngqo, lidlula kwi-filter capacitor ukuze kuzinziswe i-voltage. Zombini zahlulwe zaba ziindlela ezimbini, yonke indlela ilawulwa ngombane kusetyenziswa i-BEC, i-BEC yeyomkeli kunye ne-MCU elawulwa ngombane esetyenziswa kumbane, isiphumo esiya kwi-receiver yentambo yombane yimigca ebomvu emgceni kunye nomgca omnyama, enye ibandakanyeka kwi-MOS tube ukuze isetyenziswe yonke indlela, apha, ilawulwa ngombane ngombane, i-SCM iqalile, iqhuba i-MOS pipe vibration, yenza isandi sokuthontsiza kwemoto siphume.

Ezinye izilungiso zombane zixhotyiswe ngomsebenzi wokulinganisa i-throttle. Ngaphambi kokuba ingene kwinkqubo yokulinda, iya kujonga ukuba indawo ye-throttle iphezulu okanye iphantsi okanye iphakathi. Ukuba indawo ye-throttle iphezulu, iya kungena kuhambo lokulinganisa umbane.

Xa yonke into ilungile, ikhompyutha encinci ye-single-chip ekuhlengahlengisweni kombane iya kugqiba nge-voltage yokuphuma kunye ne-frequency kunye necala lokuqhuba kunye ne-Angle yokufaka ukuqhuba isantya semoto kwaye ijike ngokwesignali kumgca wesignali we-PWM. Lo ngumgaqo we-electromodulation ongenabhrashi.

Xa i-drive motor isebenza, amaqela amathathu e-MOS tube asebenza ngaphakathi kwe-electric modulation, amabini kwiqela ngalinye, i-positive output a control, i-control negative output, xa i-positive output, i-negative output, hayi i-negative, i-output iphezulu, yenze i-alternating current, kwakhona, ukwenza lo msebenzi, amaqela amathathu e-frequency yawo yi-8000 hz. Ukuthetha ngale nto, ukulawulwa kombane okungenabhrashi kuyafana ne-factory motor esetyenziswa kwi-frequency converter okanye kwi-governor.

Igalelo liyi-dc, lidla ngokuqhutywa ziibhetri ze-lithium. Igalelo liyi-ac yesigaba sesithathu, enokuyiqhuba ngqo i-motor.

Ukongeza, i-airmodel brushless electronic governor ikwanazo neesignali ezintathu zokufaka, isignali ye-PWM yokufaka, esetyenziselwa ukulawula isantya semoto. Kwii-aeromodels, ingakumbi kwii-aeromodels ezine-axis ezine, ii-aeromodels ezikhethekileyo ziyafuneka ngenxa yobuchule bazo.

Kutheni ke ufuna ukulungiswa kombane okukhethekileyo kwi-quad, yintoni ekhethekileyo ngayo?

I-quad inee-OARS ezine, kwaye ii-OARS ezimbini zinqamlezene. Ukujikeleza phambili kunye nokujikeleza okungasemva kwi-steering ye-paddle kunokulungisa iingxaki zokujikeleza ezibangelwa kukujikeleza kwe-blade enye.

Ububanzi be-oar nganye buncinci, kwaye amandla e-centrifugal ayasasazeka njengoko ii-OARS ezine zijikeleza. Ngokungafaniyo ne-paddle ethe tye, kukho amandla e-inertial centrifugal enye kuphela evelisa amandla e-centrifugal aqinileyo enza ipropathi ye-gyroscopic, ethintela i-fuselage ukuba ingajiki ngokukhawuleza.

Ke ngoko, ukuphindaphinda kokuhlaziywa kwesiginali yolawulo lwegiya lokuqhuba kuphantsi kakhulu.

I-axis ezine ukuze kuphendulwe ngokukhawuleza, ngenxa yotshintsho lwesimo esibangelwa kukushukuma, kufuneka kulungiswe umbane ngesantya esiphezulu, isantya sokuhlaziya se-PPM yesiqhelo elawulwa ngombane malunga ne-50 hz kuphela, ayiwanelisi imfuno elawula isantya, kwaye ulawulo lombane lwe-PPM lwe-MCU olwakhelwe ngaphakathi kwi-PID, ngaba isantya sinokutshintsha iimpawu zeenqwelo-moya zemodeli yesiqhelo ukuze zibonelele ngokugudileyo, kwi-axis ezine akufanelekanga, utshintsho lwesantya semoto olufunekayo luyimpendulo ekhawulezayo.

Ngokulungiswa kombane okukhethekileyo ngesantya esiphezulu, isignali yokulawula ukudluliselwa kwe-IIC bus interface, inokufikelela kumakhulu amawaka otshintsho lwesantya semoto ngomzuzwana, kwindiza ye-axis ezine, umzuzu wesimo sengqondo unokugcinwa uzinzile. Nokuba yimpembelelo yesiquphe yamandla angaphandle, isasebenza.
