Algorithms kula da mota gama gari don BLDC injin injin DC mara kyau

Motocin DC marasa gogewa suna yin motsi da kansu (juyin kai tsaye), don haka sun fi rikitarwa don sarrafawa.
Gudanar da motar BLDC yana buƙatar fahimtar matsayi na rotor da tsarin don gyarawa da sarrafa motar.Domin sarrafa saurin madauki, akwai ƙarin buƙatu guda biyu waɗanda za a auna saurin rotor / ko halin yanzu da siginar PWM don sarrafa saurin motar iko.
Ƙananan motar DC maras gogewaMotors na iya amfani da gefe - ko siginonin PWM na tsakiya bisa ga buƙatun aikace-aikacen.Mafi yawan aikace-aikacen suna buƙatar ayyuka daban-daban na gudu kawai kuma za su yi amfani da jeri mai zaman kanta guda shida don siginar PWM. Wannan yana ba da mafi girman ƙuduri mai yiwuwa.Idan aikace-aikacen yana buƙatar sakawa uwar garken, birki mai ƙarfi, ko juyar da wutar lantarki, ana ba da shawarar amfani da siginar PWM na gaba ɗaya.
Don fahimtar matsayi na rotor, BLDC yana ɗaukar firikwensin sakamako na Hall don samar da cikakkiyar shigarwar matsayi.Wannan yana haifar da yin amfani da ƙarin layi da farashi mafi girma.Sensorless BLDC Control yana kawar da buƙatar firikwensin Hall kuma a maimakon haka yana amfani da ƙarfin lantarki na baya (EMF). ) na mota don tsinkayar matsayi na rotor.Sensorless iko yana da mahimmanci don aikace-aikacen saurin sauye-sauye masu sauƙi kamar magoya baya da famfo.
Shigarwa da sake cika lokacin da babu kaya
Yawancin injin BLDC ba sa buƙatar ƙarin PWM, saka lokacin da ba a ɗauka ba, ko ramuwa na lokaci ba.Kawai aikace-aikacen BLDC waɗanda zasu iya buƙatar waɗannan halayen sune manyan injunan BLDC servo Motors, sinusoidal m BLDC Motors, brushless AC, ko PC synchronous motoci.
Sarrafa algorithm
Yawancin algorithms masu sarrafawa daban-daban ana amfani da su don samar da iko na BLDC Motors.Yawanci, ana amfani da transistor wutar lantarki azaman masu daidaitawa na layi don sarrafa wutar lantarki.Wannan hanyar ba ta da amfani yayin tuki manyan injiniyoyi. samar da farawa da sarrafawa ayyuka.
