Ntchito ndi mfundo yogwirira ntchito ya commutator
Commutator ntchito
The commutator makamaka imagwira ntchito yokonzanso kuti iwonetsetse kuti komwe kumayendera ma electromagnetic torque sikusintha.
1. Ikatembenuzidwa kuti igwirizane ndi maginito, waya umene unalumikizidwa ndi magetsi poyamba udzalekanitsidwa ndi burashi pa commutator yofanana, ndipo galimotoyo idzazungulira.
2. Pangani mayendedwe apano munjira yokhotakhota ya zida kuti mutsimikizire kuti komwe kumayendera ma elekitiromu kumakhalabe kosasintha.
3. Mu jenereta, commutator akhoza kusintha kuthekera kosinthika mu chinthucho kukhala mphamvu ya DC pakati pa maburashi. 4. Mu injini, imatha kusintha mawonekedwe a DC omwe amagwiritsidwa ntchito pakali pano mu chigawo cha AC, ndikupanga torque molunjika.
Momwe commutator imagwirira ntchito
Koyiloyo ikadutsa pakalipano, imazungulira kukopa ndi kunyansidwa ndi maginito okhazikika. Ikatembenukira kuti igwirizane ndi maginito, waya womwe udapatsidwa mphamvu poyambilira udzasiyanitsidwa ndi maburashi ndi zolumikizana ndi ma commutator. Chokani, ndipo maburashi amalumikizidwa ndi zolumikizana zomwe zimagwirizana ndi ma koyilo omwe amapanga mphamvu yoyendetsa, ndipo izi zimabwereza mosalekeza, ndipo mota ya DC imatembenuka. Ngati palibe woyendetsa galimoto, injiniyo imangokhala pasanathe mphindi imodzi.

Timagwiritsa ntchito makeke kuti tikupatseni kusakatula kwabwinoko, kusanthula kuchuluka kwa anthu patsamba lanu ndikusintha zomwe mumakonda. Pogwiritsa ntchito tsamba ili, mukuvomera kugwiritsa ntchito ma cookie.
