Kev tswj hwm lub cev muaj zog yog los tswj kev tig lossis nres lub cev muaj zog, thiab qhov ceev ntawm kev tig. Qhov kev tswj hwm lub cev muaj zog tseem hu ua lub tshuab tswj ceev hluav taws xob (ESC). Kev hloov kho hluav taws xob sib raug rau kev siv cov cav sib txawv, suav nrog kev hloov kho hluav taws xob brushless thiab txhuam.
Lub hlau nplaum tas mus li ntawm lub tshuab txhuam-tshuab tau ruaj khov, lub kauj vuam ncig lub rotor, thiab qhov kev taw qhia ntawm lub zog sib nqus tau hloov pauv los ntawm kev sib cuag tsis tu ncua ntawm lub txhuam thiab lub commutator kom lub rotor tig tas li.
Lub cev muaj zog tsis txhuam, raws li nws lub npe qhia, tsis muaj qhov hu ua txhuam thiab commutator. Nws lub rotor yog lub hlau nplaum tas mus li, thaum lub kauj ruaj khov. Nws txuas ncaj qha rau lub zog sab nraud.
Qhov tseeb, lub cev muaj zog brushless kuj xav tau lub hwj chim hluav taws xob, uas yog lub cev muaj zog tsav. Nws hloov qhov kev taw qhia ntawm cov hluav taws xob hauv lub kauj ruaj khov txhua lub sijhawm, kom ntseeg tau tias lub zog ntawm nws thiab lub hlau nplaum tas mus li yog qhov sib txawv thiab kev sib hloov tas mus li tuaj yeem txuas ntxiv mus.
Lub cev muaj zog tsis txhuam tau ua haujlwm yam tsis tas yuav kho hluav taws xob, kev muab hluav taws xob ncaj qha rau lub cev muaj zog tuaj yeem ua haujlwm, tab sis qhov no tsis tuaj yeem tswj qhov ceev ntawm lub cev muaj zog. Lub cev muaj zog tsis txhuam yuav tsum muaj kev kho hluav taws xob, lossis nws tsis tuaj yeem tig. Lub zog hluav taws xob ncaj qha yuav tsum tau hloov mus rau peb theem hloov hluav taws xob los ntawm kev tswj lub zog hluav taws xob tsis txhuam.
Qhov kev hloov kho hluav taws xob thaum ntxov tshaj plaws tsis zoo li qhov kev hloov kho hluav taws xob tam sim no, qhov ntxov tshaj plaws yog kev hloov kho hluav taws xob txhuam, hais qhov no koj yuav xav nug, kev hloov kho hluav taws xob txhuam yog dab tsi, thiab tam sim no kev hloov kho hluav taws xob brushless muaj qhov sib txawv li cas.
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 qhov uas tuaj yeem tig, yog tag nrho cov hlau nplaum thaiv, thiab lub kauj yog lub stator uas tsis tig, vim tsis muaj carbon txhuam hauv nruab nrab, qhov no yog lub cev muaj zog brushless.
Thiab lub tshuab txhuam hniav, raws li lub npe qhia yog txhuam carbon, yog li muaj lub tshuab txhuam hniav, zoo li peb feem ntau cov menyuam yaus ua si nrog chaw taws teeb tswj ntawm lub tshuab yog lub tshuab txhuam hniav.
Raws li ob hom tshuab hluav taws xob thiab lub npe ntawm txhuam thiab txhuam - kev tswj hwm hluav taws xob dawb. Los ntawm qhov kev pom ntawm kev tshaj lij nws yog txhuam yog qhov tso zis ntawm tam sim no ncaj qha, brushless fais fab tso zis yog peb-theem ac.
Tam sim no ncaj qha yog hluav taws xob khaws cia rau hauv peb lub roj teeb, uas tuaj yeem muab faib ua cov ncej zoo thiab cov ncej tsis zoo. Lub zog fais fab ntawm peb lub tsev 220V, siv rau lub xov tooj ntawm tes them lossis lub khoos phis tawj, yog AC. AC yog nrog qee zaus, feem ntau yog kab ntxiv thiab rho tawm, ntxiv thiab rho tawm rov qab thiab tawm; Tam sim no ncaj qha yog ib qho ncej zoo thiab ib qho ncej tsis zoo.
Tam sim no ac thiab dc tau meej lawm, hluav taws xob peb theem yog dab tsi? Raws li txoj kev xav, peb theem hloov pauv tam sim no yog ib hom hluav taws xob kis tau, hu ua hluav taws xob peb theem, uas yog tsim los ntawm peb lub peev xwm hloov pauv nrog tib lub zaus, tib lub amplitude thiab qhov sib txawv ntawm 120 degrees sib law liag.
Feem ntau hais lus, nws yog peb lub tsev neeg peb lub zog hloov pauv, ntxiv rau qhov voltage, zaus, lub kaum sab xis ntawm lub zog tsav tsheb kuj txawv, lwm yam zoo ib yam, tam sim no rau peb theem hluav taws xob thiab tam sim no ncaj qha yog nkag siab.
Brushless, lub tswv yim yog tam sim no ncaj qha, los ntawm lub lim capacitor los tswj lub voltage. Ob qho tib si ces muab faib ua ob txoj kev, tag nrho txoj kev yog electrically tswj BEC siv, BEC yog rau receiver thiab electrically tswj MCU siv nyob rau hauv lub hwj chim mov, qhov tso zis rau lub receiver ntawm lub hwj chim cord yog cov kab liab ntawm kab thiab dub kab, lwm yam yog koom nrog MOS raj siv tag nrho txoj kev, ntawm no, lub electrically tswj nrog hluav taws xob, SCM pib, tsav MOS yeeb nkab co, ua lub cev muaj zog poob dripping suab.
Qee qhov kev hloov kho hluav taws xob muaj qhov ua haujlwm calibration throttle. Ua ntej nkag mus rau hauv lub kaw lus standby, nws yuav saib xyuas seb qhov chaw throttle siab lossis qis lossis nyob nruab nrab. Yog tias qhov chaw throttle siab, nws yuav nkag mus rau hauv qhov kev hloov kho hluav taws xob calibration.
Thaum txhua yam npaj txhij lawm, lub microcomputer ib leeg-chip hauv kev kho hluav taws xob yuav txiav txim siab qhov hluav taws xob tso zis thiab zaus nrog rau kev tsav tsheb thiab lub kaum sab xis kom tsav lub cev muaj zog ceev thiab tig raws li lub teeb liab ntawm kab teeb liab PWM. Qhov no yog lub hauv paus ntsiab lus brushless electromodulation.
Thaum lub cev muaj zog tsav tsheb khiav, tag nrho peb pawg ntawm MOS raj ua haujlwm hauv kev hloov kho hluav taws xob, ob pawg hauv txhua pawg, qhov tso zis zoo yog kev tswj hwm, qhov tso zis tsis zoo yog kev tswj hwm, thaum qhov tso zis zoo, qhov tso zis tsis zoo, tsis yog qhov tsis zoo, qhov tso zis ntawm qhov tso zis yog siab heev, nws tau tsim ib qho tam sim no hloov pauv, kuj, los ua txoj haujlwm no, peb pawg ntawm lawv qhov zaus yog 8000 hz. Hais txog qhov no, kev tswj hwm hluav taws xob brushless kuj sib npaug rau lub cev muaj zog Hoobkas siv rau ntawm lub tshuab hloov pauv zaus lossis tus tswv xeev.
Lub tswv yim yog dc, feem ntau yog siv los ntawm cov roj teeb lithium. Lub tso zis yog peb-theem ac, uas tuaj yeem tsav lub cev muaj zog ncaj qha.
Ntxiv mus, lub airmodel brushless electronic governor kuj muaj peb kab input teeb liab, input PWM teeb liab, siv los tswj lub cev muaj zog ceev. Rau aeromodels, tshwj xeeb tshaj yog rau plaub-axis aeromodels, xav tau aeromodels tshwj xeeb vim lawv qhov tshwj xeeb.
Yog li ntawd, vim li cas koj thiaj xav tau kev kho hluav taws xob tshwj xeeb rau ntawm lub quad, dab tsi tshwj xeeb txog nws?
Lub quad muaj plaub lub OARS, thiab ob lub OARS yog sib tshuam. Kev tig mus tom ntej thiab kev tig rov qab ntawm lub paddle lub kauj tsheb tuaj yeem them taus cov teeb meem tig los ntawm kev tig ntawm ib rab riam.
Lub txoj kab uas hla ntawm txhua lub oar yog me me, thiab lub zog centrifugal raug faib thaum plaub lub OARS tig. Tsis zoo li lub paddle ncaj, tsuas muaj ib lub zog centrifugal inertial uas tsim lub zog centrifugal concentrated uas tsim cov khoom gyroscopic, ua kom lub fuselage tsis txhob tig sai.
Yog li ntawd, qhov zaus ntawm kev hloov kho tshiab ntawm lub kauj tsheb tswj lub teeb liab yog qhov tsawg heev.
Plaub axis kom teb tau sai, teb rau kev hloov pauv ntawm lub cev uas tshwm sim los ntawm kev txav mus los, xav tau kev hloov kho hluav taws xob ceev ceev, qhov kev hloov kho ceev ntawm PPM ib txwm muaj tsuas yog li 50 hz, tsis txaus siab rau qhov xav tau uas tswj qhov ceev, thiab PPM hluav taws xob tswj MCU ua rau hauv PID, puas tuaj yeem hloov pauv qhov ceev ntawm cov qauv dav hlau ib txwm muaj kom du, ntawm plaub axis tsis tsim nyog, plaub axis lub cev muaj zog hloov pauv qhov ceev xav tau yog qhov teb sai.
Nrog kev hloov kho hluav taws xob tshwj xeeb ceev ceev, IIC lub tsheb npav interface kis tau tus mob teeb liab, tuaj yeem ua tiav ntau pua txhiab qhov kev hloov pauv ceev ntawm lub cev muaj zog ib ob, hauv plaub-axis davhlau, lub sijhawm ntawm tus cwj pwm tuaj yeem tswj tau ruaj khov. Txawm tias los ntawm kev cuam tshuam sai ntawm cov rog sab nraud, tseem nyob ruaj khov.
