Kodi mota yopanda burashi ndi chiyani?

Kufotokozera Kwachidule kwa Brushless Motors

Brushless DC Electric Motor (BLDC) ndi mota yamagetsi yomwe imadalira kusintha kwamagetsi pogwiritsa ntchito magetsi amagetsi mwachindunji. Ngakhale kuti ma DC motors achikhalidwe akhala akutsogolera makampaniwa kwa nthawi yayitali,Ma mota a BLDCZatchuka kwambiri posachedwapa. Zinayamba chifukwa cha kubuka kwa magetsi a semiconductor m'zaka za m'ma 1960, zomwe zimathandiza kuti zipitirire patsogolo.

Kodi Dc Power ndi chiyani?

Mphamvu yamagetsi ndi kayendedwe ka ma elekitironi kudzera mu kondakitala, monga waya.

Pali mitundu iwiri ya magetsi:

Mphamvu yosinthira (AC)

Mphamvu yamagetsi yolunjika (DC)

Mphamvu yamagetsi ya AC imapangidwa ndi jeneretaInes yodziwika ndi ma elekitironi omwe nthawi ndi nthawi amasintha njira mu kondakitala, chifukwa cha alternator kapena maginito ozungulira.

Mosiyana ndi zimenezi, kayendedwe ka ma elekitironi ka DC current kamayenda mbali imodzi.Ichoimachokera ku batri kapena magetsi olumikizidwa ku chingwe cha AC.

Kufanana kwa Bldc ndi DC Motors

BLDC ndiMa mota a DCZili ndi zofanana zambiri. Mitundu yonse iwiriyi ili ndi stator yosasuntha yomwe imakhala ndi maginito okhazikika kapena maginito amagetsi kumbali yake yakunja ndi rotor yokhala ndi zozungulira zozungulira mkati, zoyendetsedwa ndi direct current. Ikaperekedwa ndi direct current, mphamvu ya maginito ya stator imayatsidwa, zomwe zimapangitsa kuti maginito a rotor ayende, zomwe zimathandiza kuti rotor izungulire. Chosinthira mphamvu (commutator) chikufunika kuti chozungulira chozunguliracho chizizungulira mosalekeza, chifukwa chimalepheretsa kugwirizana ndi mphamvu ya maginito ya stator. Chosinthira mphamvu (commutator) chimasinthasintha mphamvu yamagetsi kudzera m'ma windings, kusintha maginito ndikulola chozunguliracho kuti chizizungulira nthawi zonse malinga ngati mota ikuyendetsedwa.

Kusiyana kwa Bldc ndi DC Motors

Kusiyana kwakukulu pakati pa ma mota a BLDC ndi DC kuli mu kapangidwe kawo ka commutator. Mota ya DC imagwiritsa ntchito maburashi a kaboni pachifukwa ichi. Vuto la maburashi awa ndilakuti amavala mwachangu. Ma mota a BLDC amagwiritsa ntchito masensa, nthawi zambiri masensa a Hall, poyesa malo a rotor ndi bolodi la circuit lomwe limagwira ntchito ngati switch.
