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

Bicycle kapena e-bike ndi njinga yokhala ndigalimoto yamagetsindi batri kuthandiza wokwera. Mabasiketi amagetsi amatha kukwera mosavuta, mwachangu, komanso kosangalatsa, makamaka kwa anthu omwe amakhala kumadera amapiri kapena omwe ali ndi zofooka zathupi. Njinga yamagetsi yamagetsi ndi mota yamagetsi yomwe imasintha mphamvu yamagetsi kukhala mphamvu yamakina ndipo imagwiritsidwa ntchito pozungulira mawilo. Pali mitundu yambiri yamagetsi amagetsi, koma yodziwika kwambiri pa njinga zamagetsi ndi brushless DC mota, kapena BLDC mota.

Galimoto yopanda brushless DC ili ndi zigawo ziwiri zazikulu: rotor ndi stator. Rotor ndi gawo lozungulira lomwe lili ndi maginito okhazikika omwe amalumikizidwa pamenepo. Stator ndi gawo lomwe limakhala loyima ndipo lili ndi zozungulira zozungulira. Koyiloyo imalumikizidwa ndi chowongolera chamagetsi, chomwe chimayang'anira zomwe zikuchitika komanso mphamvu zomwe zikuyenda kudzera pa koyilo.

Wowongolera akatumiza magetsi ku koyilo, amapanga gawo lamagetsi lomwe limakopa kapena kuthamangitsa maginito okhazikika pa rotor. Izi zimapangitsa kuti rotor ikhale yozungulira. Posintha ndondomeko ndi nthawi yomwe ikuyenda panopa, wolamulira akhoza kulamulira liwiro ndi torque ya galimoto.

Ma motors a Brushless DC amatchedwa ma DC motors chifukwa amagwiritsa ntchito Direct current (DC) kuchokera pa batire. Komabe, si ma motors oyera a DC chifukwa wowongolera amatembenuza DC kukhala alternating current (AC) kuti ipangitse ma coil. Izi zimachitidwa kuti injiniyo ikhale yogwira ntchito bwino komanso yogwira ntchito, chifukwa kusinthana kwapano kumatulutsa mphamvu yamaginito yamphamvu komanso yosalala kuposa yachindunji.

Soma e-bike moteremwaukadaulo ndi ma mota a AC, koma amayendetsedwa ndi mabatire a DC ndipo amayendetsedwa ndi oyang'anira DC. Izi zimawapangitsa kukhala osiyana ndi ma mota amtundu wa AC, omwe amayendetsedwa ndi gwero la AC (monga gridi kapena jenereta) ndipo alibe wowongolera.

Ubwino wogwiritsa ntchito brushless DC motors panjinga zamagetsi ndi:

Ndiwogwira ntchito bwino komanso amphamvu kuposa ma motors a DC omwe amapangidwa ndi brushed, omwe maburashi ake amatha ndipo amapanga mikangano ndi kutentha.

Ndiwodalirika komanso olimba kuposa ma motors a DC omwe ali ndi brushed chifukwa ali ndi magawo ochepa osuntha ndipo amafunikira chisamaliro chochepa.

Ndiwophatikizika komanso opepuka kuposa ma mota a AC, omwe ali ndi zinthu zokulirapo komanso zolemetsa monga ma transfoma ndi ma capacitor.

Amakhala osinthasintha komanso osinthika kuposa ma mota a AC chifukwa amatha kuwongoleredwa mosavuta ndikusinthidwa ndi wowongolera.

Kufotokozera mwachidule,ma e-bike moterendi ma motors a DC opanda brush omwe amagwiritsa ntchito mphamvu ya DC kuchokera ku batire ndi mphamvu ya AC kuchokera kwa wowongolera kuti apange kuyenda kozungulira. Ndiwo mtundu wabwino kwambiri wamagalimoto opangira ma e-njinga chifukwa chakuchita bwino kwambiri, mphamvu, kudalirika, kulimba, kuphatikizika, kupepuka, kusinthasintha, komanso kusinthasintha.
