Kodi njinga zamagetsi zimagwiritsa ntchito ma AC motors kapena ma DC motors?

Njinga yamagetsi kapena njinga yamagetsi ndi njinga yokhala ndimota yamagetsindi batire kuti zithandize wokwera. Njinga zamagetsi zingathandize kukwera mosavuta, mwachangu, komanso kosangalatsa, makamaka kwa anthu okhala m'madera amapiri kapena omwe ali ndi zofooka zakuthupi. Njinga zamagetsi ndi injini zamagetsi zomwe zimasintha mphamvu zamagetsi kukhala mphamvu zamakanika ndipo zimagwiritsidwa ntchito kuzungulira mawilo. Pali mitundu yambiri ya ma mota zamagetsi, koma yodziwika kwambiri pa njinga zamagetsi ndi galimoto ya DC yopanda burashi, kapena mota ya BLDC.

Mota ya DC yopanda burashi ili ndi magawo awiri akuluakulu: rotor ndi stator. Rotor ndi gawo lozungulira lomwe lili ndi maginito okhazikika omangiriridwa. Stator ndi gawo lomwe limakhala losasunthika ndipo lili ndi ma coil ozungulira. Coil imalumikizidwa ndi chowongolera chamagetsi, chomwe chimayang'anira mphamvu ndi magetsi omwe akuyenda kudzera mu coil.

Wowongolera akatumiza mphamvu yamagetsi ku coil, amapanga mphamvu yamagetsi yomwe imakopa kapena kuthamangitsa maginito okhazikika pa rotor. Izi zimapangitsa kuti rotor izungulire mbali inayake. Mwa kusintha ndondomeko ndi nthawi ya kayendedwe ka mphamvu, wowongolera amatha kuwongolera liwiro ndi mphamvu ya injini.

Ma mota a DC opanda brushless amatchedwa ma mota a DC chifukwa amagwiritsa ntchito mphamvu yolunjika (DC) yochokera ku batri. Komabe, si ma mota a DC enieni chifukwa chowongolera chimasintha DC kukhala mphamvu yosinthira (AC) kuti ipatse mphamvu ma coil. Izi zimachitika kuti ziwongolere magwiridwe antchito ndi magwiridwe antchito a mota, chifukwa mphamvu yosinthira imapanga mphamvu ya maginito yamphamvu komanso yosalala kuposa mphamvu yolunjika.

Somota zamagalimoto apakompyutaMwaukadaulo, ndi ma mota a AC, koma amayendetsedwa ndi mabatire a DC ndipo amayendetsedwa ndi ma DC controller. Izi zimawasiyanitsa ndi ma mota achikhalidwe a AC, omwe amayendetsedwa ndi gwero la AC (monga gridi kapena jenereta) ndipo alibe chowongolera.

Ubwino wogwiritsa ntchito ma mota a DC opanda maburashi mu njinga zamagetsi ndi:

Ndi amphamvu komanso ogwira ntchito bwino kuposa ma mota a DC opangidwa ndi brushed, omwe maburashi awo amawonongeka ndipo amapanga kukangana ndi kutentha.

Ndi odalirika komanso olimba kuposa ma mota a DC opangidwa ndi brushed chifukwa ali ndi zida zochepa zosuntha ndipo safuna kukonza kwambiri.

Ndi zazing'ono komanso zopepuka kuposa ma mota a AC, omwe ali ndi zinthu zazikulu komanso zolemera monga ma transformer ndi ma capacitor.

Ndi zosinthasintha komanso zosinthika kuposa ma mota a AC chifukwa zimatha kuyendetsedwa mosavuta ndikusinthidwa ndi chowongolera.

Mwachidule,mota zamagalimoto apakompyutaNdi ma mota a DC opanda brushless omwe amagwiritsa ntchito mphamvu ya DC kuchokera ku batri ndi mphamvu ya AC kuchokera ku chowongolera kuti apange kuyenda kozungulira. Ndi mtundu wabwino kwambiri wa mota wa e-bikes chifukwa cha kugwira ntchito bwino, mphamvu, kudalirika, kulimba, kufupika, kupepuka, kusinthasintha, komanso kusinthasintha.
