Ukulawulwa kwe-motor drive ukulawula ukujikeleza kwemoto noma ukumisa, kanye nesivinini sokuzungeza.Ingxenye yokulawula idrayivu yemoto ibizwa nangokuthi isilawuli sesivinini se-electronic (ESC).Ukulungiswa kukagesi okuhambisana nokusetshenziswa kwamamotho ahlukene, okuhlanganisa ukulungiswa kwe-brushless kanye ne-brush kagesi.
Uzibuthe unomphela we-brush-motor ulungisiwe, ikhoyili ilimala eduze kwe-rotor, futhi isiqondiso se-magnetic field sishintshwa ukuxhumana okungapheli phakathi kwebhulashi kanye ne-commutator ukugcina i-rotor ijikeleza ngokuqhubekayo.
I-brushless motor, njengoba igama layo libonisa, ayinakho lokho okubizwa ngokuthi ibhulashi kanye ne-commutator.I-rotor yayo iwuzibuthe unomphela, kuyilapho ikhoyili ilungisiwe.Ixhumeke ngqo kumandla angaphandle.
Eqinisweni, i-brushless motor nayo idinga umbusi we-elekthronikhi, okuyi-motor drive.Ishintsha isiqondiso se-current ngaphakathi kwekhoyili engaguquki nganoma yisiphi isikhathi, ukuze kuqinisekiswe ukuthi amandla phakathi kwayo nozibuthe ongunaphakade ayanyanyeka ngokulinganayo futhi ukuzungeza okuqhubekayo kungaqhutshekwa.
I-brushless motor ingasebenza ngaphandle kwesidingo sokulungiswa kagesi, ukunikezwa kukagesi okuqondile enjini kungasebenza, kodwa lokhu akukwazi ukulawula isivinini semoto.Injini ye-brushless kumele ibe nokulungiswa kukagesi, noma ayikwazi ukuzungeza.Imodi yamanje eqondile kufanele iguqulwe ibe kathathu - isigaba esishintshashintshayo samanje ngokulawula kwamanje kwe-brushless.
Ukulungiswa kokuqala kukagesi akufani nokulungiswa kagesi kwamanje, okokuqala ngqa ukulungiswa kagesi kwebhulashi, wathi lokhu ungase ufune ukubuza, kuyini ukulungiswa kagesi kwebhulashi, futhi manje ukulungiswa kukagesi okungenalutho kunamuphi umehluko.
Eqinisweni, kukhona umehluko omkhulu phakathi kwe-brushless kanye ne-brushless zisekelwe injini.Manje i-rotor ye-motor, okuyingxenye engakwazi ukujikeleza, yiyona yonke i-magnet block, futhi ikhoyili yi-stator engazungezi, ngoba ayikho ibhulashi le-carbon phakathi, lena yi-brushless motor.
Futhi injini yebhulashi, njengoba negama lisho ukuthi ibhulashi lekhabhoni, ngakho-ke kukhona injini yebhulashi, njengoba ngokuvamile thina izingane sidlala ngesilawuli kude senjini iyinjini yebhulashi.
Ngokusho kwezinhlobo ezimbili zemishini kagesi kanye negama lebhulashi nebhulashi - ukulawulwa kukagesi kwamahhala.Ngokombono wochwepheshe ibhulashi liwumphumela wamanje oqondile, ukuphuma kwamandla okungenalutho kuyisigaba sesithathu se-ac.
I-Direct current ugesi ogcinwe ebhethrini lethu, ongahlukaniswa ube izigxobo ezinhle nezingezinhle.Amandla kagesi asendlini yethu angu-220V, asetshenziselwa ishaja yomakhalekhukhwini noma ikhompuyutha, i-ac.Ac inefrikhwensi ethile, ukukhuluma ngokuvamile kuwumugqa wokuhlanganisa nokususa, kanye nokususa nokushintshanisa emuva naphambili; isigxobo nesigxobo esingesihle.
Manje njengoba sekucacile ukuthi i-ac ne-dc iyini ugesi wezigaba ezintathu?Ngokwenkolelo-mbono, i-alternating current enezigaba ezintathu iwuhlobo lokudlulisa ugesi, okubizwa ngokuthi ugesi wezigaba ezintathu, ohlanganisa amandla amathathu ashintshanayo afanayo. imvamisa, i-amplitude efanayo kanye nomehluko wesigaba wamadigri ayi-120 ngokulandelana.
Ngokuvamile, kuba indlu yethu ezintathu kushintshana zamanje, ngaphezu voltage, imvamisa, drive Angle ihlukile, ezinye ziyafana, manje ngoba ugesi wezigaba ezintathu kanye zamanje ngqo kuyaqondakala.
I-Brushless, okokufaka kungokwamanje okuqondile, ngokusebenzisa i-capacitor yokuhlunga ukuze kuqiniswe i-voltage.Zombili bese zihlukaniswa zibe umgwaqo emibili, yonke indlela ilawulwa ngogesi ukusetshenziswa kwe-BEC, i-BEC ingeyomamukeli kanye ne-MCU elawulwa ngogesi esetshenziswa ekunikezeni amandla, okukhiphayo ukuze umamukeli wentambo yamandla imigqa ebomvu kulayini nomugqa omnyama, omunye uhilelekile ku-MOS tube ukusebenzisa yonke indlela, lapha, okulawulwa ngogesi ngogesi, i-SCM yaqala, shayela ukudlidliza kwepayipi le-MOS, yenza amaconsi emoto aconse. umsindo.
Okunye ukulungiswa kukagesi kufakwe umsebenzi wokulinganisa i-throttle.Ngaphambi kokungena kusistimu yokulinda, izoqapha ukuthi indawo ye-throttle iphezulu noma iphansi noma iphakathi.Uma i-throttle position iphezulu, izongena ekulinganisweni kohambo lokulungiswa kukagesi.
Uma konke sekumi ngomumo, i-single-chip microcomputer ekulungiseni kukagesi izonquma amandla kagesi aphumayo kanye nemvamisa kanye nesiqondiso sokushayela kanye ne-Angle yokufaka ukushayela isivinini semoto bese ijika ngokuvumelana nesignali ekulayini wesignali ye-PWM. Isimiso se-brushless electromodulation.
Lapho injini yokushayela isebenza, ingqikithi yamaqembu amathathu eshubhu le-MOS asebenza ngaphakathi kokuguquguquka kukagesi, amabili eqenjini ngalinye, okukhiphayo okuhle njengokulawula, okukhiphayo okulawulwayo okungekuhle, lapho okukhiphayo okuhle, okukhiphayo okungalungile, hhayi okungalungile, okukhiphayo okukhiphayo kukhulu, kuye kwakha i-alternating current, futhi, ukwenza lo msebenzi, amaqembu amathathu emvamisa yawo yi-8000 hz.Ukukhuluma ngalokhu, ukulawulwa kwe-brushless kagesi nakho kufana nemoto yefekthri esetshenziswa ku-converter frequency noma umbusi.
Okokufaka kuyi-dc, ngokuvamile inikwe amandla amabhethri e-lithium.Okukhiphayo kuyisigaba sesithathu se-ac, esingashayela imoto ngokuqondile.
Ngaphezu kwalokho, umbusi we-airmodel brushless electronic futhi unemigqa emithathu yokufaka isignali, isignali ye-PWM yokufaka, esetshenziselwa ukulawula isivinini se-motor.Kuma-aeromodels, ikakhulukazi ama-aeromodels amane-axis, ama-aeromodel akhethekile ayadingeka ngenxa yobuchwepheshe bawo.
Ngakho-ke kungani udinga ukushuna okukhethekile kukagesi ku-quad, yini ekhethekile ngakho?
I-quad ine-OARS emine, futhi ama-OARS amabili acishe abe yi-crisscross.Ukuzungezisa phambili nokuzungezisa emuva esiteringini se-paddle kungase kususe izinkinga zokuzungeza okubangelwa ukuzungezisa kweblade eyodwa.
Ububanzi besigwedlo ngasinye buncane, futhi amandla amaphakathi ayahlakazeka njengoba i-OARS emine izungeza. Ngokungafani ne-paddle eqondile, kukhona amandla aphakathi nendawo angena ngaphakathi akhiqiza amandla agxilile ayi-centrifugal akha impahla ye-gyroscopic, egcina i-fuselage ingajiki. ngokushesha.
Ngakho-ke, imvamisa yokubuyekezwa kwesiginali yokulawula igiya lokuqondisa iphansi kakhulu.
Ama-eksisi amane ukuze aphendule ngokushesha, ekuphenduleni izinguquko ze-postural ezibangelwa ukukhukhuleka, adinga ugesi okwazi ukushintshwa ngesivinini esikhulu, isivinini sokuvuselela se-PPM evamile elawulwa ngogesi kuphela mayelana ne-50 hz, asenelisi isidingo sokulawula isivinini, kanye ne-PPM kagesi. lawula i-MCU eyakhelwe ngaphakathi ye-PID, ingakwazi ukushintsha isivinini izici zemodeli yendiza evamile ukuze inikeze ngokushelelayo, ku-eksisi emine ayifanelekile, izinguquko ezine zesivinini se-axis motor ezidingekayo ukusabela okusheshayo.
Ngokulungiswa okukhethekile kagesi okunesivinini esikhulu, isignali yokulawula ukudluliselwa kwesixhumi esibonakalayo sebhasi ye-IIC, ingafinyelela amakhulu ezinkulungwane zezinguquko zejubane lemoto ngomzuzwana, endizeni ye-four-axis, umzuzu wokucabanga ungagcinwa uzinzile.Ngisho nomthelela ongazelelwe wamandla angaphandle, namanje iphelele.
