Yintoni i-brushless motor kwaye isebenza njani?

Yintoni i-brushless motor kwaye isebenza njani?Le mibuzo siza kuyiphendula kweli nqaku.

Kwiminyaka yezixhobo zamandla zanamhlanje kunye nezixhobo, akumangalisi ukuba ii-motor brushless zixhaphake kakhulu kwiimveliso esizithengayo.Nangona i-brushless motor yaqalwa phakathi kwinkulungwane ye-19, ayizange isebenze ngokurhweba de kwangowe-1962.

I-Brushless motor, ngenxa yokusebenza kwayo kakuhle, ukuhanjiswa kwetorque egudileyo, ukuqina okuphezulu kunye nesantya esiphezulu sokubaleka, ngokuthe ngcembe ithatha indawo yemoto yokuzoba.Izicelo zabo, kwixesha elidlulileyo, zincitshiswe kakhulu ngeendleko ezongezelelweyo zabalawuli beemoto eziyinkimbinkimbi, ezifunekayo ukuba zisebenze i-motor.

Ukusebenza kwangaphakathi kwezi njini zimbini ziyafana.Xa ikhoyili yemoto inamandla, idala imagnethi yethutyana egxotha okanye itsale umazibuthe osisigxina.

Amandla avelayo aguqulwa abe kukujikeleza kwe-shaft ukwenza i-motor isebenze.Njengoko i-shaft ijikeleza, i-current iqondiswe kwiikhoyili ezahlukeneyo, ukwenzela ukuba i-magnetic field igcinwe inomdla kwaye igxothwe, ivumela i-rotor ukuba ijikeleze ngokuqhubekayo.

I-brushless motor isebenza ngakumbi kunemoto yokuzoba kwinkqubo yokuguqula amandla ombane kumandla oomatshini.Abanayo i-commutator, enciphisa ukugcinwa kunye nobunzima, kwaye inciphisa ukuphazamiseka kwe-electromagnetic.

Bangakwazi ukuphuhlisa i-torque ephezulu, impendulo efanelekileyo yesantya, kwaye inokulawula ngokulula i-chip eyodwa (iyunithi yokulawula imoto).

Zikwasebenza ngaphakathi koluhlu olubanzi lwesantya, zivumela ulawulo lwentshukumo elungileyo kunye netorque ekuphumleni.

I-brushless motor kunye ne-wire drawing motor zahluke kakhulu kwisakhiwo.

Ibrashi isetyenziselwa i-brush motor ukuhambisa i-current kwi-windings ngokusebenzisa abafowunelwa be-commutator.

Nangona kunjalo, i-brushless motor ayifuni i-commutator.Umhlaba wemagnethi wemoto utshintshwa sisixhobo sokukhulisa isandi esibangelwa sisixhobo esibuyisela umva.Umzekelo yi-optical encoder yokulinganisa iintshukumo ezilungileyo kuba azixhomekeke kwisigaba sokunyakaza.

I-windings kwi-motor yokudweba ibekwe kwi-rotor kwaye ibekwe kwi-brushless motor stator.Isidingo sebrashi sinokupheliswa ngokubeka ikhoyili kwindawo emileyo ye-stator okanye i-motor.

Ngamafutshane, umahluko omkhulu phakathi kwe-brushless motor kunye ne-motor brushed kukuba akukho magnethi angatshintshiyo kunye neengcingo ezijikelezayo (i-brushless), kunye ne-brushless motors ineengcingo ezisisigxina kunye neemagnethi ezijikelezayo.Inzuzo ephambili yi-brushless motor ngaphandle kokukhuhlana, ngoko ukunciphisa ubushushu kunye nokuphucula ukusebenza kakuhle.
