Yakajairika mota control algorithms ye BLDC brushless DC mota

Brushless DC mota dzinozvifambisa (self-direction conversion), saka dzakanyanya kuoma kudzora.
BLDC mota control inoda kunzwisiswa kwenzvimbo yerotor uye mashandiro ekugadzirisa uye kutungamira kwemota.Pakuvharwa loop kumhanya kudzora, pane zvimwe zviviri zvinodiwa kuti rotor kumhanya / kana mota ikozvino uye PWM chiratidzo kuyerwa kudzora kumhanya kwemota uye. simba.
Diki brushless DC motamota dzinogona kushandisa edge - kana centre-array PWM masiginecha zvinoenderana nezvinodiwa zvekushandisa.Mazhinji maapplication anoda chete velocity-varying operations uye achashandisa matanhatu akazvimirira edge arrays yePWM sign.Izvi zvinopa iyo yepamusoro resolution inogoneka.Kana application ichida server positioning, simba braking, kana simba reversal, kushandiswa kweinopindirana centre-array PWM chiratidzo kunokurudzirwa.
Kuti unzwe nzvimbo ye rotor, BLDC inotora Hall effect sensor kuti ipe nzvimbo yakakwana induction.Izvi zvinotungamirira kushandiswa kwemitsara yakawanda uye mari yakakwirira.Sensorless BLDC control inobvisa kudiwa kweHoro sensor uye panzvimbo iyo inoshandisa kumashure electromotive force (EMF). ) yemotokari kufanotaura nzvimbo ye rotor.Sensorless control inokosha kune yakaderera-inodhura yakasiyana-siyana yekumhanya yakadai semafeni nemapombi.Mukushandiswa kweBLDC motokari, firiji uye air conditioning compressor inodawo sensorless control.
Kuiswa uye kuzadzazve pasina-mutoro nguva
Mazhinji eBLDC mota haadi anopindirana PWM, hapana-mutoro nguva yekuisa, kana hapana-mutoro nguva muripo.The chete BLDC zvikumbiro zvingada hunhu uhwu ndehwepamusoro-performance BLDC servo motors, sinusoidal excited BLDC motors, brushless AC, kana PC synchronous. mota.
Kudzora algorithm
Zvizhinji zvakasiyana-siyana zvekugadzirisa maitiro anoshandiswa kupa kutonga kweBLDC motors.Kazhinji, magetsi emagetsi anoshandiswa semagetsi ekugadzirisa magetsi ekugadzirisa magetsi.Iyi nzira haibatsiri paunenge uchityaira magetsi emagetsi.Magetsi makuru emagetsi anofanira kunge ari PWM anodzorwa uye anoda microcontroller kupa kutanga uye kutonga mabasa.
