Ukulawulwa kokushayela kwemoto ukulawula ukujikeleza kwemoto noma ukuma kwayo, kanye nesivinini sokujikeleza. Ingxenye yokulawula ukushayela kwemoto ibizwa nangokuthi isilawuli sejubane le-elekthronikhi (ESC). Ukulungiswa kukagesi okuhambisana nokusetshenziswa kwama-motor ahlukene, kufaka phakathi ukulungiswa kukagesi okungenamabhulashi kanye nebhulashi.
Imagnethi ehlala njalo ye-brush-motor iqinile, ikhoyili izungezwe i-rotor, futhi isiqondiso sensimu yamagnetic sishintshwa ukuxhumana okungaguquki phakathi kwebhulashi ne-commutator ukuze i-rotor iqhubeke ijikeleza njalo.
Injini engenamabhulashi, njengoba igama layo lisho, ayinayo ibhulashi kanye ne-commutator. I-rotor yayo iyimagnethi ehlala njalo, kuyilapho ikhoyili iqinile. Ixhunywe ngqo kugesi wangaphandle.
Eqinisweni, injini engenamabhulashi idinga ne-governor kagesi, okuyi-motor drive. Ishintsha indlela yamanje ngaphakathi kwe-fixed coil nganoma yisiphi isikhathi, ukuze kuqinisekiswe ukuthi amandla aphakathi kwayo ne-unomphela aphikisana futhi ukujikeleza okuqhubekayo kungaqhubeka.
Injini engenamabhulashi ingasebenza ngaphandle kwesidingo sokulungiswa kukagesi, ukunikezwa kukagesi ngqo enjinini kungasebenza, kodwa lokhu akukwazi ukulawula isivinini senjini. Injini engenamabhulashi kumele ibe nokulungiswa kukagesi, noma ayikwazi ukujikeleza. Injini eqondile kumele iguqulwe ibe yinjini eshintshashintshayo yesigaba sesithathu ngomthetho wamanje ongenamabhulashi.
Ukulungiswa kukagesi kokuqala akufani nokulungiswa kukagesi kwamanje, kokuqala ukulungiswa kukagesi kwebhulashi, kusho lokhu ungase ufune ukubuza, kuyini ukulungiswa kukagesi kwebhulashi, manje ukulungiswa kukagesi okungenabhulashi kunomehluko muni.
Eqinisweni, kunomehluko omkhulu phakathi kwe-brushless ne-brushless ezisekelwe ku-motor. Manje i-rotor ye-motor, okuyingxenye ekwazi ukuzungeza, iyi-magnet block kuphela, kanti i-coil iyi-stator engazungezi, ngoba ayikho i-carbon brush phakathi, lena yi-brushless motor.
Futhi injini yebhulashi, njengoba igama lisho, iyibhulashi yekhabhoni, ngakho-ke kukhona injini yebhulashi, njengoba sivame ukudlala nezingane ngesilawuli kude senjini iyinjini yebhulashi.
Ngokusho kwezinhlobo ezimbili zemishini kagesi kanye negama lebhulashi nebhulashi - ukulawulwa kukagesi okungenawo. Ngokombono wobungcweti, ibhulashi liwumphumela wamandla aqondile, ukukhishwa kwamandla okungenamabhulashi kuyi-ac yesigaba sesithathu.
Ugesi oqondile ugesi ogcinwe ebhethrini lethu, ongahlukaniswa ngama-pole amahle nangalungile. Ugesi wendlu yethu ongu-220V, osetshenziselwa ishaja yocingo noma ikhompyutha, u-ac. Ugesi uvame ukuba nomugqa wokushintshana phakathi kwe-plus ne-minus, i-plus ne-minus; Ugesi oqondile uyisigxobo esihle nesisigxobo esihle.
Manje njengoba i-ac ne-dc sezicacile, iyini ugesi wezigaba ezintathu? Ngokusho kwenkolelo-mbono, i-alternating current yezigaba ezintathu iwuhlobo lokudlulisa ugesi, olubizwa ngokuthi ugesi wezigaba ezintathu, olwakhiwe amandla amathathu ashintshanayo anemvamisa efanayo, ubukhulu obufanayo kanye nomehluko wezigaba wama-degrees angu-120 ngokulandelana.
Ngokuvamile, yindlu yethu enama-current amathathu ashintshanayo, ngaphezu kwe-voltage, imvamisa, i-drive Angle ihlukile, ezinye ziyafana, manje ugesi wesigaba sesithathu kanye nowamanje oqondile kuyaqondakala.
Ngaphandle kwebhulashi, okokufaka kungumshini oqondile, nge-capacitor yesihlungi ukuze kuqiniswe i-voltage. Zombili zahlukaniswa zaba umgwaqo ezimbili, yonke indlela ilawulwa ngogesi kusetshenziswa i-BEC, i-BEC ingeye-receiver kanye ne-MCU elawulwa ngogesi esetshenziswa ekunikezeni ugesi, okukhiphayo ku-receiver yentambo yamandla yimigqa ebomvu emgqeni kanye nomugqa omnyama, omunye uhilelekile ku-MOS tube ukuze usetshenziswe yonke indlela, lapha, okulawulwa ngogesi ngogesi, i-SCM yaqala, ishayela i-MOS pipe vibration, yenza umsindo we-motor drops drops.
Ezinye izinguquko zikagesi zifakwe umsebenzi wokulinganisa i-throttle. Ngaphambi kokungena ohlelweni lokulinda, luzoqapha ukuthi isikhundla se-throttle siphezulu noma siphansi noma siphakathi. Uma isikhundla se-throttle siphezulu, sizongena ohambweni lokulinganisa ukulungiswa kukagesi.
Uma konke sekulungile, i-microcomputer ene-chip eyodwa ekulungisweni kukagesi izonquma i-voltage yokuphuma kanye nemvamisa kanye nesiqondiso sokushayela kanye ne-Angle yokufaka ukushayela isivinini semoto bese ijika ngokwesignali emugqeni wesignali we-PWM. Lesi yisimiso se-electromodulation esingenamabhulashi.
Uma injini yokushayela isebenza, amaqembu amathathu e-MOS tube asebenza ngaphakathi kokuguqulwa kukagesi, amabili eqenjini ngalinye, umphumela omuhle ukulawula, umphumela omubi wokulawula, lapho umphumela omuhle, umphumela omubi, hhayi omubi, umphumela womphumela uphezulu, wakhe ugesi oshintshashintshayo, futhi, ukuze wenze lo msebenzi, amaqembu amathathu emvamisa yawo angama-8000 hz. Uma sikhuluma ngalokhu, ukulawulwa kukagesi okungenamabhulashi nakho kufana nemoto yasefektri esetshenziswa ku-frequency converter noma ku-governor.
Okufakwayo kuyi-dc, ngokuvamile kuqhutshwa amabhethri e-lithium. Okukhiphayo kuyi-ac yesigaba sesithathu, engashayela imoto ngqo.
Ngaphezu kwalokho, i-airmodel engenamabhulashi kagesi i-governor nayo inemigqa emithathu yokufaka isignali, isignali ye-PWM yokufaka, esetshenziselwa ukulawula isivinini senjini. Kumamodeli ezindizayo, ikakhulukazi kumamodeli ezindizayo ane-axis ezine, kudingeka amamodeli ezindizayo akhethekile ngenxa yobukhulu bawo.
Ngakho-ke kungani udinga ukulungiswa okukhethekile kukagesi ku-quad, yini ekhethekile ngayo?
I-quad inama-OARS amane, kanti ama-OARS amabili ahlukene kakhulu. Ukujikeleza phambili kanye nokujikeleza okuphambene nesiteringi se-paddle kungalungisa izinkinga zokujikeleza ezibangelwa ukuzungeza kwe-blade eyodwa.
Ububanzi besigwedlo ngasinye buncane, futhi amandla e-centrifugal ayahlakazeka njengoba ama-OARS amane ejikeleza. Ngokungafani ne-paddle eqondile, kukhona amandla e-inertial centrifugal eyodwa kuphela ekhiqiza amandla e-centrifugal agxilile akha isici se-gyroscopic, okuvimbela i-fuselage ukuthi ingaphenduki ngokushesha.
Ngakho-ke, imvamisa yokuvuselelwa kwesiginali yokulawula igiya lokuqondisa iphansi kakhulu.
Ama-axis amane ukuze kuphendulwe ngokushesha, ngenxa yezinguquko zesimo esibangelwa ukukhukhuleka, kudinga ukulungiswa kukagesi ngesivinini esikhulu, isivinini sokuvuselelwa kwe-PPM evamile elawulwa ngogesi cishe ama-hz angu-50 kuphela, awanelisi isidingo esilawula isivinini, kanye ne-PPM kagesi yokulawula i-MCU eyakhelwe ngaphakathi, ingabe isivinini singashintsha izici zendiza evamile ukuze inikeze ubushelelezi, kuma-axis amane akufanele, izinguquko zesivinini semoto yama-axis amane ezidingekayo ziyimpendulo esheshayo.
Ngokulungiswa kukagesi okukhethekile kwesivinini esikhulu, isignali yokulawula ukudluliselwa kwe-interface yebhasi ye-IIC, ingafinyelela amakhulu ezinkulungwane zezinguquko zesivinini semoto ngomzuzwana, endizeni enama-axis amane, umzuzu wesimo ungagcinwa uzinzile. Ngisho nangomthelela ongazelelwe wamandla angaphandle, usaphelele.
