Reverse direction yeBLDC mota

Usati wanyura mu BLDC mota sarudzo dzemhinduro, zvakakosha kuti unzwisise kuti sei uchidzida.BLDC motors inogona kugadzirwa kwechikamu chimwe chete, nhanho mbiri uye nhatu nhanho; Iyo yakajairika dhizaini ndeye matatu-phase.Nhamba yezvikamu inoenderana nenhamba ye stator windings, nepo nhamba ye rotor magnetic poles inogona kuva chero nhamba zvichienderana nekushandiswa. zvinodiwa.Sezvo rotor yemotokari yeBLDC inobatwa nemapuranga anotenderera e stator, nzvimbo ye stator pole inofanira kuteverwa kuti ibudirire kutyaira zvikamu zvitatu zvemotokari.Nechinangwa ichi, mutongi wemotokari anoshandiswa kugadzira nhanho-nhanho yekufambisa nzira pa. matatu motor phases.Idzi nhanho nhanhatu (kana macommutators) dzinofambisa nzvimbo ye electromagnetic, izvo zvinozoita kuti magineti erotor aenderere mberi kufambisa shaft yemotor.

Nekutora iyi yakajairwa mota commutation sequence, mutyairi wemota anogona kushandisa yakakwira-frequency pulse wide modulation (PWM) chiratidzo kudzikisa zvinobudirira avhareji yemagetsi anotakurwa nemota uye nekudaro kuchinja kumhanya kwemota. dhizaini inoshanduka nekuve nevolti imwe sosi inowanikwa kune dzakasiyana siyana mota, kunyangwe iyo DC voltage sosi iri pamusoro peiyo mota yakayereswa voltage.Kuitira kuti sisitimu irambe ichishanda zvakanaka pane tekinoroji yebhurashi, yakasimba kwazvo yekudzora loop inoda kuiswa pakati pemotokari uye mutongi.Apa ndipo apo maitiro emhinduro anokosha;Kuti uchengetedze kutonga kwakarurama kwemotokari, mutongi anofanira kugara achiziva nzvimbo chaiyo ye stator maererano ne rotor.Chero kukanganisa kana kuchinja kwechikamu mune zvinotarisirwa uye chaizvoizvo. zvigaro zvinogona kuguma nemamiriro asingatarisirwi uye kuderedzwa kwekuita.Kune nzira dzakawanda dzekuwana mhinduro iyi maererano necomm.utation of BLDC mota, asi chinonyanya kuzivikanwa ndechekushandisa horo effect sensors, encoders, kana rotary transformers.Mukuwedzera, mamwe maapplication anovimbawo ne sensorless commutator tekinoroji kuti awane mhinduro.
