Ihame ryo kugenzura ibinyabiziga bidafite amashanyarazi

Igenzura rya moteri ni ukugenzura ibizunguruka cyangwa guhagarara, hamwe n umuvuduko wo kuzunguruka. Igice cyo kugenzura ibinyabiziga nacyo cyitwa elegitoronike yihuta (ESC) .Guhindura amashanyarazi bijyanye no gukoresha moteri zitandukanye, harimo no gukaraba amashanyarazi no gukaraba.

Imashini ihoraho ya brush-moteri irakosowe, coil irakomereka kuri rotor, kandi icyerekezo cyumurima wa magneti gihindurwa no guhuza guhagarara hagati ya brush na commutator kugirango rotor ikomeze.

Brushless moteri, nkuko izina ryayo ribigaragaza, ntabwo ifite icyo bita brush na commutator.Rotor yayo ni rukuruzi ihoraho, mugihe coil ikosowe.Ihujwe mu buryo butaziguye n'amashanyarazi yo hanze.

Mubyukuri, moteri idafite amashanyarazi nayo ikenera guverineri wa elegitoroniki, ahanini ni moteri.Irahindura icyerekezo cyumuyaga imbere muri coil ihamye umwanya uwariwo wose, kugirango tumenye neza ko imbaraga ziri hagati yacyo na rukuruzi zihoraho zanga kandi kuzenguruka bishobora gukomeza.

Moteri idafite amashanyarazi irashobora gukora bidakenewe ko hahindurwa amashanyarazi, gutanga amashanyarazi kuri moteri birashobora gukora, ariko ibi ntibishobora kugenzura umuvuduko wa moteri. Moteri itagira amashanyarazi igomba guhindura amashanyarazi, cyangwa ntishobora kuzunguruka. Umuyoboro utaziguye ugomba guhinduka kuri bitatu - icyiciro gisimburana nubu by brushless current regulation.

Guhindura amashanyarazi kwambere ntabwo bisa no guhinduranya amashanyarazi, icyambere ni uguhindura amashanyarazi ya brush, yavuze ibi ushobora kuba ushaka kubaza, guhinduranya amashanyarazi ni iki, kandi ubu amashanyarazi adafite amashanyarazi afite itandukaniro.

Mubyukuri, hari itandukaniro rinini hagati ya brushless na brushless ishingiye kuri moteri.Noneho rotor ya moteri, nigice gishobora kuzunguruka, ni yose ya magneti, kandi coil ni stator idahinduka, kuko nta cyuma cya karuboni kiri hagati, iyi ni moteri idafite umwanda.

Kandi moteri ya brush, nkuko izina ribigaragaza ni brush ya karubone, nuko hariho moteri ya brush, nkuko dusanzwe abana dukina hamwe na kure ya moteri ni moteri ya brush.

Ukurikije ubwoko bubiri bwimashini zikoresha amashanyarazi nizina rya brush na brush - kugenzura amashanyarazi kubuntu.Mu rwego rwumwuga nukubona ko ari brush nigisohoka cyumuyaga utaziguye, amashanyarazi adafite amashanyarazi ni ibyiciro bitatu ac.

Umuyoboro utaziguye ni amashanyarazi abitswe muri bateri yacu, ashobora kugabanywamo ibice byiza kandi bibi.Amashanyarazi yo murugo rwacu 220V, akoreshwa mumashanyarazi ya terefone igendanwa cyangwa mudasobwa, ni ac.Ac hamwe numurongo runaka, mubisanzwe nukuvuga umurongo wongeyeho na minus, wongeyeho na minus inyuma no guhanahana amakuru; Umuyoboro utaziguye ni mwiza inkingi na pole mbi.

Noneho ko ac na dc bisobanutse, amashanyarazi yicyiciro cya gatatu ni iki? Ukurikije inyigisho, ibyiciro bitatu bisimburana ni uburyo bwo kohereza amashanyarazi, byitwa amashanyarazi yibice bitatu, bigizwe nubushobozi butatu busimburana kandi bumwe? inshuro, amplitude imwe hamwe nicyiciro gitandukanya dogere 120 zikurikiranye.

Muri rusange, ni urugo rwacu ibintu bitatu bisimburana, usibye voltage, inshuro, gutwara Angle iratandukanye, ibindi birasa, ubu kumashanyarazi yibyiciro bitatu kandi byerekanwa byumvikana.

Brushless, ibyinjira nibyerekezo bitaziguye, binyuze mumashanyarazi ya filteri kugirango ihagarike voltage. Byombi noneho bigabanijwe mumihanda ibiri, inzira yose igenzurwa namashanyarazi gukoresha BEC, BEC ni iyakira kandi igenzurwa namashanyarazi MCU ikoreshwa mumashanyarazi, ibisohoka kuri uwakira umugozi w'amashanyarazi ni imirongo itukura kumurongo n'umurongo wumukara, undi agira uruhare muri tube ya MOS kugirango akoreshe inzira zose, hano, igenzurwa n'amashanyarazi n'amashanyarazi, SCM yatangiye, gutwara imiyoboro ya MOS ihindagurika, ituma ibitonyanga bya moteri bitonyanga ijwi.

Guhindura amashanyarazi bimwe bifite ibikoresho bya kalibrasi.Mbere yo kwinjira muri sisitemu yo guhagarara, izagenzura niba imyanya ya trottle iri hejuru cyangwa hasi cyangwa hagati.Niba imyanya ya trottle iri hejuru, izinjira muri kalibrasi yurugendo rwo guhindura amashanyarazi.

Iyo ibintu byose byiteguye, microcomputer imwe-chip muguhindura amashanyarazi bizahitamo ibyasohotse mumashanyarazi hamwe ninshuro kimwe nicyerekezo cyo gutwara no kwinjiza Angle kugirango utware umuvuduko wa moteri hanyuma uhindukire ukurikije ibimenyetso biri kumurongo wa signal ya PWM.Ibi ni byo brushless electromodulation ihame.

Iyo moteri ya moteri ikora, amatsinda atatu yose ya MOS tube akora mumashanyarazi, abiri muri buri tsinda, umusaruro mwiza ugenzura, kugenzura ibintu bibi, iyo umusaruro mwiza, umusaruro mubi, ntabwo ari mubi, ibisohoka ibisohoka ni byinshi, byashizeho ubundi buryo bwo guhinduranya, nanone, kugirango ukore iki gikorwa, amatsinda atatu yumurongo wazo ni 8000 hz. Tuvuze ibi, amabwiriza y’amashanyarazi adafite amashanyarazi nayo ahwanye na moteri yinganda ikoreshwa kuri enterineti cyangwa guverineri.

Iyinjiza ni dc, mubisanzwe ikoreshwa na bateri ya lithium.Ibisohoka ni ac-fasi eshatu ac, ishobora gutwara moteri itaziguye.

Mubyongeyeho, guverineri wa elegitoroniki ya elegitoronike ya elegitoronike nayo ifite imirongo itatu yinjiza ibimenyetso, ibyapa bya PWM byinjira, bikoreshwa mukugenzura umuvuduko wa moteri. Kuri aeromodels, cyane cyane kuri aeromodeli enye, hakenewe aeromodeli idasanzwe kubera umwihariko wabo.

None se kuki ukeneye guhuza amashanyarazi yihariye kuri quad, niki kidasanzwe kuri yo?

Quad ifite OARS enye, kandi OARS zombi zirasa na crisscross.Ihinduranya ryimbere hamwe no guhinduranya kuzunguruka kuri podle irashobora gukemura ibibazo byizunguruka biterwa no kuzunguruka icyuma kimwe.

Diameter ya buri oar ni nto, kandi imbaraga za centrifugal ziratatana nkuko OARS enye zizunguruka.Ntabwo bimeze nka padiri igororotse, hariho imbaraga imwe gusa ya centrifugal itanga imbaraga yibanze ya centrifugal ikora imitungo ya giroskopi, bigatuma fuselage idahinduka. vuba.

Kubwibyo, inshuro zo kuvugurura ibimenyetso byo kugenzura ibikoresho ni bike cyane.

Imirongo ine kugirango isubizwe vuba, mugusubiza impinduka zumwanya zatewe na drift, zikenera umuvuduko mwinshi wamashanyarazi, umuvuduko wo kuvugurura amashanyarazi asanzwe ya PPM ugenzurwa namashanyarazi nka hz 50 gusa, ntabwo uhaza ibikenewe kugenzura umuvuduko, hamwe n amashanyarazi ya PPM kugenzura MCU yubatswe muri PID, irashobora guhindura umuvuduko wibiranga indege isanzwe yindege kugirango itange neza, kumurongo ine ntabwo ikwiye, impinduka enye za moteri ya moteri ikenewe ni reaction yihuse.

Hamwe n'umuvuduko mwinshi udasanzwe wo guhinduranya amashanyarazi, ibimenyetso bya bisi ya bisi ya bisi yo kugenzura, irashobora kugera ku bihumbi amagana byihuta bya moteri ku isegonda, mu ndege ya axis enye, umwanya wimyifatire urashobora gukomeza guhagarara neza.Nubwo n'ingaruka zitunguranye zingufu zituruka hanze, biracyaza idahwitse.
