Lub cev muaj zog tsav tswj yog tswj lub cev muaj zog tig los yog nres, thiab qhov ceev ntawm kev sib hloov.Lub cev muaj zog tsav tswj ib feem tseem hu ua hluav taws xob ceev tswj (ESC).Kev hloov hluav taws xob sib raug rau kev siv cov motors sib txawv, nrog rau kev hloov hluav taws xob txhuam thiab txhuam.
Cov hlau nplaum ruaj khov ntawm txhuam-lub cev muaj zog yog tsau, lub kauj yog qhov txhab nyob ib ncig ntawm lub rotor, thiab cov kev taw qhia ntawm cov hlau nplaum hloov pauv los ntawm kev sib txuas tsis tu ncua ntawm tus txhuam thiab cov commutator kom lub rotor tig tsis tu ncua.
Brushless lub cev muaj zog, raws li nws lub npe qhia, tsis muaj qhov hu ua txhuam thiab commutator. Nws lub rotor yog cov hlau nplaum ruaj khov, thaum lub kauj yog tsau. Nws yog txuas ncaj qha mus rau sab nraud fais fab mov.
Qhov tseeb, lub cev muaj zog brushless kuj xav tau ib tus tswv xeev hluav taws xob, uas yog qhov pib tsav lub cev muaj zog. Nws hloov cov kev taw qhia ntawm tam sim no nyob rau hauv lub taag kauj nyob rau hauv txhua lub sij hawm, thiaj li yuav xyuas kom meej tias lub zog ntawm nws thiab cov hlau nplaum mus tas li yog ob leeg repulsive thiab lub nruam rotation yuav ua tau mus ntxiv.
Brushless lub cev muaj zog tuaj yeem ua haujlwm yam tsis xav tau kev hloov kho hluav taws xob, kev xa hluav taws xob ncaj qha rau lub cev muaj zog tuaj yeem ua haujlwm, tab sis qhov no tuaj yeem tswj tsis tau lub cev muaj zog.Brushless lub cev muaj zog yuav tsum muaj kev hloov hluav taws xob, lossis nws tsis tuaj yeem tig.Direct tam sim no yuav tsum tau hloov mus rau peb - theem alternating tam sim no los ntawm brushless tam sim no kev cai.
Qhov kev hloov kho hluav taws xob ntxov tshaj plaws tsis zoo li qhov kev hloov kho hluav taws xob tam sim no, qhov ntxov tshaj plaws yog kev hloov hluav taws xob txhuam, hais tias qhov no koj yuav xav nug, qhov kev hloov kho hluav taws xob txhuam yog dab tsi, thiab tam sim no qhov kev hloov hluav taws xob brushless muaj qhov sib txawv.
Qhov tseeb, muaj qhov sib txawv loj ntawm brushless thiab brushless yog raws li lub cev muaj zog. Tam sim no lub rotor ntawm lub cev muaj zog, uas yog ib feem uas yuav tig tau, yog tag nrho cov hlau nplaum thaiv, thiab lub kauj yog lub stator tsis tig, vim hais tias tsis muaj carbon txhuam nyob rau hauv nruab nrab, qhov no yog lub brushless lub cev muaj zog.
Thiab txhuam lub cev muaj zog, raws li lub npe qhia yog cov txhuam hniav, yog li muaj lub tshuab txhuam hniav, zoo li peb feem ntau cov menyuam yaus ua si nrog cov chaw taws teeb tswj lub cev muaj zog yog txhuam lub cev muaj zog.
Raws li ob hom khoom siv hluav taws xob thiab lub npe ntawm txhuam thiab txhuam - tsis muaj hluav taws xob tswj kev tswj hwm.Los ntawm kev tshaj lij ntawm kev pom nws yog txhuam hniav yog qhov tso tawm ntawm cov hluav taws xob ncaj qha, brushless lub zog tso tawm yog peb-theem ac.
Direct tam sim no yog cov hluav taws xob khaws cia hauv peb lub roj teeb, uas tuaj yeem muab faib ua cov ncej zoo thiab tsis zoo. Lub hwj chim ntawm peb tsev neeg 220V, siv rau lub xov tooj ntawm tes charger los yog lub computer, yog ac.Ac yog nrog ib tug tej zaus, feem ntau hais lus yog ib tug kab ntawm ntxiv thiab rho tawm, ntxiv thiab rho tawm rov qab thiab tawm mus pauv; Ib tug ncaj tam sim no yog ib tug zoo. ncej thiab ncej tsis zoo.
Tam sim no hais tias ac thiab dc yog qhov tseeb, peb-theem hluav taws xob yog dab tsi? Raws li txoj kev xav, peb-theem alternating tam sim no yog ib qho kev xa hluav taws xob, hu ua peb-theem hluav taws xob, uas yog tsim los ntawm peb lub peev xwm sib hloov nrog tib yam. zaus, tib lub amplitude thiab theem sib txawv ntawm 120 degrees successively.
Feem ntau hais lus, nws yog peb tsev neeg peb hloov tam sim no, ntxiv rau qhov voltage, zaus, tsav lub kaum sab xis yog qhov sib txawv, lwm yam yog tib yam, tam sim no rau peb theem hluav taws xob thiab cov hluav taws xob ncaj qha tau nkag siab.
Brushless, cov tswv yim yog ncaj qha tam sim no, los ntawm lub lim capacitor kom stabilize qhov voltage.Ob ntawm ces muab faib ua ob txoj kev, tag nrho txoj kev yog hluav taws xob tswj BEC siv, BEC yog rau receiver thiab hluav taws xob tswj MCU siv nyob rau hauv lub hwj chim mov, cov zis rau lub receiver ntawm lub hwj chim qaum yog cov kab liab ntawm txoj kab thiab kab dub, lwm tus yog koom nrog MOS raj siv txhua txoj kev, ntawm no, cov khoom siv hluav taws xob tswj hluav taws xob, SCM pib, tsav MOS yeeb nkab kev co, ua rau lub cev muaj zog dripping. suab.
Qee qhov kev hloov kho hluav taws xob tau nruab nrog lub zog calibration muaj nuj nqi. Ua ntej nkag mus rau hauv qhov system standby, nws yuav saib xyuas seb txoj haujlwm throttle yog siab lossis qis lossis hauv nruab nrab. Yog hais tias lub throttle txoj hauj lwm siab, nws yuav nkag mus rau hauv lub calibration ntawm kev hloov hluav taws xob taug kev.
Thaum txhua yam npaj txhij, lub microcomputer ib leeg-chip hauv kev hloov kho hluav taws xob yuav txiav txim siab qhov tso zis voltage thiab zaus raws li kev tsav tsheb thiab cov tswv yim lub kaum sab xis kom tsav lub cev muaj zog thiab tig raws li cov teeb liab ntawm PWM teeb liab kab. brushless electromodulation txoj cai.
Thaum tsav lub cev muaj zog khiav, tag nrho peb pawg ntawm MOS raj ua haujlwm nyob rau hauv hluav taws xob hloov kho, ob qho tib si hauv txhua pab pawg, qhov zoo tso tawm ib qho kev tswj, kev tswj tsis zoo, thaum cov zis zoo, cov zis tsis zoo, tsis zoo, cov zis tawm ntawm cov zis yog heev, nws tau tsim ib tug alternating tam sim no, kuj, ua hauj lwm no, peb pawg ntawm lawv zaus yog 8000 hz.Hais txog qhov no, brushless hluav taws xob tswj kuj yog sib npaug rau lub Hoobkas motor siv nyob rau hauv zaus converter los yog tswv xeev.
Cov tswv yim yog dc, feem ntau yog siv los ntawm cov roj teeb lithium.Cov zis yog peb-theem ac, uas tuaj yeem tsav lub cev muaj zog ncaj qha.
Tsis tas li ntawd, airmodel brushless electronic Governor kuj muaj peb lub teeb liab input kab, input PWM teeb liab, siv los tswj lub cev muaj zog ceev.Rau aeromodels, tshwj xeeb tshaj yog rau plaub-axis aeromodels, tshwj xeeb aeromodels yog xav tau vim lawv tshwj xeeb.
Yog li vim li cas koj thiaj li xav tau kev kho hluav taws xob tshwj xeeb ntawm lub quad, dab tsi tshwj xeeb txog nws?
Lub quad muaj plaub OARS, thiab ob lub OARS kuj yog crisscross.Qhov kev sib hloov mus rau pem hauv ntej thiab thim rov qab ntawm lub paddle lub kauj tsheb tuaj yeem cuam tshuam cov teeb meem tig los ntawm kev sib hloov ntawm ib rab riam.
Qhov txoj kab uas hla ntawm txhua lub oar yog me me, thiab lub zog centrifugal yog dispersed raws li plaub OARS rotate.Tsis zoo li ib tug ncaj paddle, muaj tsuas yog ib tug inertial centrifugal quab yuam uas generates ib tug concentrated centrifugal quab yuam uas tsim ib tug gyroscopic khoom, ua kom lub fuselage los ntawm tig. sai sai.
Yog li ntawd, qhov zaus ntawm kev hloov tshiab ntawm lub kauj iav tswj lub teeb liab yog tsawg heev.
Plaub axis kom ceev cov lus teb, nyob rau hauv cov lus teb rau postural hloov los ntawm drift, xav tau kev kub ceev hluav taws xob adjustable, lub renewal ceev ntawm pa PPM hluav taws xob tswj tsuas yog hais txog 50 hz, tsis txaus siab rau qhov kev xav tau uas tswj qhov ceev, thiab PPM hluav taws xob. tswj MCU built-in PID, tuaj yeem hloov ceev cov yam ntxwv ntawm cov qauv qauv dav hlau los muab kev sib tw, ntawm plaub axis tsis tsim nyog, plaub axis lub cev muaj zog hloov pauv hauv kev xav tau yog cov tshuaj tiv thaiv sai.
Nrog kev kub ceev tshwj xeeb kev hloov hluav taws xob, IIC tsheb npav interface kis tau tus mob teeb liab, tuaj yeem ua tiav ntau pua txhiab lub cev muaj zog hloov pauv ib ob, nyob rau hauv plaub-axis davhlau, tus cwj pwm lub sijhawm tuaj yeem tswj tau ruaj khov. tsis zoo.
