Wopanga ma vibration motor akufotokoza momwe DC motor imagwirira ntchito

Malinga ndiwopanga injini yogwedera, mfundo yogwirira ntchito yamota ya DCndikusintha mphamvu yamagetsi yosinthika yomwe imapangidwa ndi kulowetsedwa mu coil ya armature kukhala mphamvu yamagetsi yolunjika pamene ikukokedwa kuchokera kumapeto kwa burashi ndi commutator ndi ntchito ya commutator ya burashi.

Kuchokera ku ntchito ya commutator kufotokoza: burashi siwonjezera mphamvu ya DC, ndi choyendetsa chachikulu chokoka armature counterclockwise constant speed rotation, mbali ziwiri za coil motsatana kudula mzere wa mphamvu ya maginito pansi pa polarity yosiyana ya magnetic pole, ndipo momwe induction idapangira mphamvu ya electromotive, mphamvu ya electromotive motsatira lamulo la dzanja lamanja kuti lidziwe.

Popeza kuti armature imazungulira mosalekeza, ndikofunikira kuti kondakitala wonyamula magetsi aziyikidwa m'mphepete mwa coil ab ndi CD mu mphamvu yamaginito kuti adule mizere ya mphamvu pansi pa N ndi S poles motsatizana, ngakhale kuti malangizo a mphamvu yamagetsi yomwe imayambitsa pamphepete mwa coil iliyonse komanso mu coil yonse akusinthana.

Mphamvu yamagetsi yomwe imayambitsa mu coil ndi mphamvu yamagetsi yosinthasintha, pomwe mphamvu yamagetsi yomwe ili kumapeto kwa burashi A ndi B ndi mphamvu yamagetsi yamagetsi ya A.

Chifukwa, pozungulira armature, mosasamala kanthu komwe armature imatembenukira, chifukwa cha commutator ndi burashi commutator action, mphamvu ya electromotive yomwe imabwera chifukwa cha burashi A kudzera mu tsamba la commutator nthawi zonse imakhala mphamvu ya electromotive yomwe ili m'mphepete mwa coil yomwe imadula mzere wa n-pole magnetic field. Chifukwa chake, burashi A nthawi zonse imakhala ndi A positive polarity.

Mofananamo, burashi B nthawi zonse imakhala ndi polarity yoyipa, kotero kumapeto kwa burashi kumatha kuyambitsa mphamvu ya pulse electromotive yolunjika nthawi zonse koma kukula kwake kumasiyana. Ngati chiwerengero cha ma coil pansi pa pole iliyonse chawonjezeka, kuchuluka kwa kugwedezeka kwa pulse kungachepe ndipo mphamvu ya electromotive ya dc ikhoza kupezeka.

Umu ndi momwe ma mota a dc amagwirira ntchito. Zimasonyezanso kuti mota ya sub - dc kwenikweni ndi jenereta ya ac yokhala ndi commutator.

Malinga ndi kuyambitsidwa kwa opanga ma vibration motors, kuchokera ku electromagnetic situation yoyambira, mota ya DC kwenikweni imatha kugwira ntchito ngati mota yothamanga, komanso imatha kuyendetsedwa ngati jenereta, koma zoletsa zake ndizosiyana.

Pamapeto awiri a mota ya DC, onjezani magetsi a DC, lowetsani mphamvu zamagetsi mu armature, mphamvu yamakina yotuluka kuchokera ku shaft ya mota, kokerani makina opangira, mphamvu yamagetsi kukhala mphamvu yamakina ndikukhala mota;

Ngati choyendetsa chachikulu chikugwiritsidwa ntchito kukoka armature ya mota ya dc, ndipo burashiyo siwonjezera mphamvu ya dc, ndiye kuti kumapeto kwa burashi kungayambitse mphamvu ya electromotive ya dc ngati gwero lamagetsi la dc, lomwe lingathe kutulutsa mphamvu zamagetsi. Motayo imasintha mphamvu yamakina kukhala mphamvu zamagetsi ndipo imakhala mota ya jenereta.

Mfundo yakuti mota yomweyo ingagwire ntchito ngati mota yamagetsi kapena jenereta. Mu chiphunzitso cha injini imatchedwa mfundo yosinthika.

Mungakonde:
