Ukulawulwa kwemoto kukulawula ukujikeleza kweemoto okanye ukumisa, kunye nesantya sokujikeleza.Inxalenye yokulawula i-motor drive ibizwa ngokuba yi-electronic speed controller (ESC) .Uhlengahlengiso lombane oluhambelana nokusetyenziswa kweenjini ezahlukeneyo, kubandakanywa i-brushless kunye ne-brush uhlengahlengiso lombane.
Imagnethi esisigxina ye-brush-motor igxininiswe, i-coil inxeba malunga ne-rotor, kwaye isalathiso se-magnetic field sitshintshwa ngoqhagamshelwano olungapheliyo phakathi kwebrashi kunye ne-commutator ukugcina i-rotor ijikeleza ngokuqhubekayo.
Injini yebhrashi, njengoko igama layo libonisa, ayinayo into ebizwa ngokuba yibrashi kunye ne-commutator. I-rotor yayo yimagnethi esisigxina, ngelixa i-coil igxininiswe. Idityaniswe ngokuthe ngqo kunikezelo lwamandla lwangaphandle.
Ngapha koko, i-brushless motor ikwafuna irhuluneli ye-elektroniki, eyona nto iyimoto yokuqhuba. Itshintsha isalathiso sangoku ngaphakathi kwikhoyili esisigxina nanini na, ukwenzela ukuba kuqinisekiswe ukuba amandla phakathi kwayo kunye nemagnethi esisigxina iyaphikisana kwaye ukujikeleza okuqhubekayo kunokuqhubeka.
I-motor Brushless inokusebenza ngaphandle kwemfuneko yohlengahlengiso lombane, unikezelo oluthe ngqo lombane kwi-motor inokusebenza, kodwa le nto ayikwazi ukulawula isantya semoto.Injini ye-brushless kufuneka ibe nohlengahlengiso lombane, okanye ayinakujikeleza.Ngoku ngqo kufuneka iguqulwe ibe mithathu - Isigaba sokutshintshana kwangoku ngommiselo wangoku we-brushless.
Ulungelelwaniso lokuqala lombane alufani nohlengahlengiso lwangoku lombane, ulungelelwaniso lombane lwebhrashi, uthe oku ungafuna ukubuza, yintoni uhlengahlengiso lombane lwebhrashi, kwaye ngoku uhlengahlengiso lombane olungena brushless lunawuphi umahluko.
Enyanisweni, kukho umahluko omkhulu phakathi kwe-brushless kunye ne-brushless zisekelwe kwi-motor. Ngoku i-rotor ye-motor, eyona nxalenye inokujikeleza, yiyo yonke ibhloko yamagnetic, kwaye i-coil yi-stator engajikeleziyo, kuba akukho bhobho ye-carbon phakathi, le yi-motor brushless.
Kwaye ibhrashi yemoto, njengoko negama libonisa ukuba yibrashi yekhabhoni, ngoko ke kukho ibhrashi yemoto, njengoko siqhele ukudlala ngolawulo olukude lwemoto yimoto yebrashi.
Ngokutsho kweentlobo ezimbini koomatshini bombane kunye negama ibrashi kunye ibrashi - free regulation yombane.Ngokwembono yobungcali ibrashi yimveliso yangoku ngqo, imveliso brushless amandla inqanaba ezintathu-ac.
Umsinga othe ngqo ngumbane ogcinwe kwibhetri yethu, enokwahlulwa ibe ziipali ezilungileyo nezingalunganga. Umbane wendlu yethu eyi-220V, esetyenziselwa itshaja yefowuni ephathwayo okanye ikhompyuter, i-ac.Ac inezambuko ezithile, xa sithetha ngokubanzi ngumgca wokudibanisa kunye nokuthabatha, dibanisa kwaye uthabathe emva naphambili utshintsho; ipali kunye nepali engalunganga.
Ngoku ukuba i-ac ne-dc zicacile, yintoni umbane wezigaba ezithathu? Ngokwethiyori, inqanaba lesithathu i-alternating current yindlela yokuhambisa umbane, ekubhekiselwa kuyo njengombane wezigaba ezithathu, equlunqwe ngamathuba amathathu atshintshanayo ngokufanayo. frequency, i-amplitude efanayo kunye nokwahlukana kwesigaba se-120 degrees ngokulandelelana.
Ngokuqhelekileyo, yindlu yethu emithathu etshintshanayo yangoku, ukongeza kumbane, i-frequency, i-Angle ye-drive yahlukile, ezinye ziyafana, ngoku umbane wesigaba sesithathu kunye nombane othe ngqo uyaqondwa.
Brushless, igalelo langoku ngqo, ngokusebenzisa capacitor filter ukuzinzisa voltage.Zombini ke yahlulahlulwe indlela ezimbini, yonke indlela elawulwa ngombane BEC ukusetyenziswa, BEC yeyommkeli kunye nombane elawulwa MCU esetyenziswa kunikezelo lombane, imveliso ukuze umamkeli wentambo yamandla yimigca ebomvu kumgca kunye nomgca omnyama, enye ibandakanyeka kwi-tube ye-MOS ukusebenzisa yonke indlela, apha, umbane olawulwa ngombane, i-SCM yaqala, ukuqhuba ukungcangcazela kombhobho we-MOS, yenza i-motor drops ithontsiza. isandi.
Ezinye izilungiso zombane zixhotyiswe nge-throttle calibration function. Ngaphambi kokungena kwinkqubo yokulinda, iya kubeka iliso ukuba indawo ye-throttle iphezulu okanye iphantsi okanye iphakathi. Ukuba indawo ye-throttle iphezulu, iya kungena kwi-calibration yohambo lohlengahlengiso lombane.
Xa yonke into ilungile, i-microcomputer ye-single-chip kuhlengahlengiso lombane iya kuthatha isigqibo malunga nombane ophumayo kunye ne-frequency kunye nesikhokelo sokuqhuba kunye ne-Angle yokufaka i-Angle yokuqhuba isantya semoto kwaye ijike ngokuhambelana nomqondiso kumgca wophawu lwe-PWM. brushless electromodulation umgaqo.
Xa i-motor yokuqhuba iqhuba, itotali yamaqela amathathu etyhubhu ye-MOS asebenza ngaphakathi kokumodareyitha kombane, amabini kwiqela ngalinye, isiphumo esilungileyo singulawulo, imveliso engalunganga yolawulo, xa isiphumo esilungileyo, isiphumo esibi, isiphumo esibi, hayi kakubi, imveliso imveliso iphezulu, iye yakha i-alternating current, kwakhona, ukwenza lo msebenzi, amaqela amathathu okuphindaphinda kwawo yi-8000 hz. Ukuthetha oku, ukulawulwa kombane we-brushless kukwalingana nemoto yefektri esetyenziswa kwi-converter frequency okanye irhuluneli.
Igalelo li-dc, ngokuqhelekileyo lixhaswe ngamabhetri e-lithium.Isiphumo sisigaba sesithathu se-ac, esinokuqhuba i-motor ngqo.
Ukongezelela, i-airmodel ye-brushless ye-electronic governor nayo inemigca emithathu yokufaka impawu, igalelo le-PWM yesignali, esetyenziselwa ukulawula isivinini se-motor.Kwi-aeromodels, ngakumbi kwii-aeromodels ezine-axis, ii-aeromodels ezikhethekileyo ziyafuneka ngenxa yobungcali bazo.
Ke kutheni ufuna ukulungiswa kombane okukhethekileyo kwiquad, yintoni ekhethekileyo ngayo?
I-quad ine-OARS ezine, kwaye i-OARS ezimbini ziphantse zibe crisscross.Ukujikeleza phambili kunye nokujikeleza umva kwi-paddle steering kunokuphelisa iingxaki ze-spin ezibangelwa ukujikeleza kwe-blade enye.
Idayamitha yephini ngalinye lincinci, kwaye amandla aphakathi asasazwa njengoko i-OARS ezine zijikeleza.Ngokungafaniyo nephini lokubheqa elithe tye, kukho kuphela amandla angaphakathi angasebenziyo avelisa amandla agxininisiweyo we-centrifugal enza ipropathi ye-gyroscopic, egcina ifuselage ekujikeni. ngokukhawuleza.
Ke ngoko, ukuphindaphindwa kohlaziyo lwesiginali yokulawula igiya liphantsi kakhulu.
I-axis emine ukwenzela ukuphendula ngokukhawuleza, ekuphenduleni utshintsho lwe-postural olubangelwa yi-drift, ludinga isantya esiphezulu sombane esilungelelanisiweyo, isantya sokuhlaziya i-PPM eqhelekileyo elawulwa ngombane kuphela malunga ne-50 hz, ayanelisi imfuno yokulawula isantya, kunye ne-PPM yombane. lawula i-MCU eyakhelwe-ngaphakathi ye-PID, inokutshintsha isantya iimpawu zemodeli yesiqhelo yenqwelomoya ukubonelela ngokugudileyo, kwi-axis emine ayifanelekanga, iinguqu ezine zesantya se-axis motor eziyimfuneko kukusabela ngokukhawuleza.
Ngesantya esiphezulu uhlengahlengiso olukhethekileyo lombane, i-IIC i-bus interface control transmission control signal, inokufikelela kumakhulu amawaka eenguqu zesantya semoto ngomzuzwana, kwi-flight-four-axis flight, umzuzu wesimo sengqondo unokugcinwa uzinzile.Nangona impembelelo yequbuliso yamandla angaphandle, kusenjalo. yomelele.
