Udindo wa Hall Effect ICs mu BLDC Motor
Ma IC a Hall effect amachita gawo lofunikira kwambiri mu ma mota a BLDC pozindikira malo a rotor, zomwe zimathandiza kuwongolera bwino nthawi ya kayendedwe ka magetsi kupita ku ma stator coils.
Njinga ya BLDCKulamulira
Monga momwe chithunzichi chikusonyezera, makina owongolera mota a BLDC amazindikira malo a rotor yozungulira ndipo pambuyo pake amalangiza dalaivala wowongolera mota kuti asinthe mphamvu kupita ku coil, potero kuyambitsa kuzungulira kwa mota.
Kuzindikira malo a rotor ndi gawo lofunikira pa njirayi.
Kulephera kuzindikira malo a rotor kumalepheretsa gawo la mphamvu kuti lisagwiritsidwe ntchito panthawi yoyenera kuti pakhale ubale wabwino pakati pa stator ndi rotor, zomwe zimapangitsa kuti pakhale kupanga torque yosakwanira.
Poipa kwambiri, injiniyo sidzazungulira.
Ma IC a Hall effect amazindikira malo a rotor mwa kusintha mphamvu yawo yotulutsa mphamvu akazindikira mphamvu ya maginito.
Kuyika kwa Hall Effect IC mu BLDC Motor
Monga momwe chithunzichi chikusonyezera, ma IC atatu a Hall effect amagawidwa mofanana pa 360° (electrical angle) circumference ya rotor.
Zizindikiro zotuluka za ma IC atatu a Hall omwe amazindikira mphamvu ya maginito ya rotor zimasintha mogwirizana ndi 60° iliyonse yozungulira kuzungulira 360° kwa rotor.
Kuphatikiza kwa zizindikiro kumeneku kumasintha mphamvu yamagetsi yomwe ikuyenda kudzera mu coil. Mu gawo lililonse (U, V, W), rotor imapatsidwa mphamvu ndipo imazungulira 120° kuti ipange S pole/N pole.
Kukopa kwa maginito ndi kukana komwe kumachitika pakati pa rotor ndi coil kumapangitsa kuti rotor izungulire.
Kusamutsa mphamvu kuchokera ku dera loyendetsa kupita ku coil kumasinthidwa malinga ndi nthawi yotulutsa ya Hall effect IC kuti pakhale kuwongolera kogwira mtima.
Chimene chimaperekama motors ogwedera opanda burashiKodi moyo wautali ndi wotani? Kugwiritsa Ntchito The Hall Effect poyendetsa Brushless Motors. Timagwiritsa ntchito Hall Effect kuwerengera malo a mota ndikusintha chizindikiro cha drive moyenerera.
Zithunzi izi zikuwonetsa momwe chizindikiro cha drive chimasinthira ndi zotsatira kuchokera ku masensa a Hall Effect.
Funsani Akatswiri Anu Atsogoleri
Timakuthandizani kupewa mavuto kuti mupereke khalidwe labwino komanso kuyamikira zosowa zanu za injini yaing'ono yopanda maburashi, panthawi yake komanso pa bajeti.
