Igenzura rusange rya moteri ya algorithms ya BLDC brushless moteri ya DC

Moteri ya Brushless DC irigendagenda (kwiyobora kwiyobora), kuburyo bigoye kugenzura.
Igenzura rya moteri ya BLDC risaba gusobanukirwa umwanya wa rotor hamwe nuburyo bwo gukosora no kuyobora moteri.Kugenzura umuvuduko wihuta wafunzwe, haribintu bibiri byongeweho bisabwa ko umuvuduko wa rotor / cyangwa moteri ya moteri hamwe nikimenyetso cya PWM bipimwa kugirango ugenzure umuvuduko wa moteri kandi imbaraga.
Moteri ntoya ya DCmoteri irashobora gukoresha impande - cyangwa hagati-yerekana ibimenyetso bya PWM ukurikije ibisabwa bisabwa. Porogaramu nyinshi zisaba gusa ibikorwa bitandukanye byihuta kandi bizakoresha ibice bitandatu byigenga byerekana ibimenyetso bya PWM.Ibi bitanga ibisubizo bihanitse bishoboka.Niba porogaramu isaba umwanya wa seriveri, feri yingufu, cyangwa imbaraga zisubira inyuma, gukoresha ikoreshwa ryuzuzanya hagati-array ibimenyetso bya PWM birasabwa.
Kugirango twumve umwanya wa rotor, BLDC ifata sensor ya salle ya Hall kugirango itange imyanya yuzuye.Ibi biganisha ku gukoresha imirongo myinshi nigiciro cyinshi. Igenzura rya BLDC ridafite imbaraga rikuraho ibikenerwa na sensor ya Hall ahubwo ikoresha imbaraga zinyuma zamashanyarazi (EMF) .
Kwinjiza no kuzuza igihe nta-mutwaro
Moteri nyinshi za BLDC ntizisaba kuzuzanya PWM, nta gihe cyo kwinjizamo igihe, cyangwa nta gihe cyo kwishyurwa.Ibisabwa byonyine bya BLDC bishobora gusaba ibyo biranga ni moteri ya BLDC ikora cyane, moteri ya sinusoidal ishimishije moteri ya BLDC, AC idafite amashanyarazi, cyangwa PC ikomatanya PC moteri.
Kugenzura algorithm
Algorithms nyinshi zitandukanye zo kugenzura zikoreshwa mugutanga igenzura rya moteri ya BLDC.Ubusanzwe, transistors yamashanyarazi ikoreshwa nkumurongo ugenzura umurongo wa moteri ya moteri.Ubu buryo ntabwo bukoreshwa mugihe utwara moteri y’amashanyarazi menshi. Moteri nini y’amashanyarazi igomba kugenzurwa na PWM kandi igasaba microcontroller kuri gutanga imirimo yo gutangira no kugenzura.
