Kodi mfundo yogwirira ntchito ya DC motor ndi iti?

Kodi mota ya DC imagwira ntchito bwanji?

Mota ya DC ndi makina omwe amasintha mphamvu zamagetsi kukhala mphamvu yamakina munjira yozungulira. Kuyenda kwake kumachitika chifukwa cha machitidwe enieni a maginito amagetsi.Mota ya DC Muli ma inductor mkati, omwe amapanga mphamvu ya maginito yomwe imagwiritsidwa ntchito popanga kayendedwe. Koma kodi mphamvu ya maginito iyi imasintha bwanji ngati mphamvu ya DC ikugwiritsidwa ntchito?  

Magetsi amagetsi, omwe ndi chidutswa cha chitsulo chokulungidwa ndi waya wozungulira womwe uli ndi magetsi ogwiritsidwa ntchito m'malo ake olumikizira magetsi. Ngati maginito awiri okhazikika awonjezeredwa mbali zonse ziwiri za maginito awa, mphamvu zonyansa komanso zokopa zimapanga mphamvu.  

Kenako, pali mavuto awiri oti athetsedwe: kupatsa mphamvu zamagetsi ku maginito ozungulira popanda mawaya kupotoka, ndikusintha njira ya mphamvu zamagetsi panthawi yoyenera. Mavuto onsewa amathetsedwa pogwiritsa ntchito zipangizo ziwiri: cholumikizira chogawanika, ndi maburashi awiri.

Monga momwe zikuonekera, commutator ili ndi magawo awiri omwe amalumikizidwa ku terminal iliyonse ya electromagnet, kupatula mivi iwiri pali maburashi omwe amagwiritsa ntchito mphamvu yamagetsi ku electromagnet yozungulira.mota yogwederaMa mota a DC amapezeka mipata itatu m'malo mwa maburashi awiri ndi awiri.

Mwanjira imeneyi, pamene maginito amagetsi akuyenda, polarity yake ikusintha ndipo shaft ikhoza kupitiliza kuzungulira. Ngakhale zitakhala zosavuta ndipo zikumveka kuti zigwira ntchito bwino, pali mavuto ena omwe amachititsa kuti mphamvu zamagalimoto awa zisagwire ntchito bwino komanso zisakhazikike, vuto lalikulu ndi chifukwa cha nthawi yomwe polarity inversion iliyonse imachitika. Popeza polarity mu maginito amagetsi amasinthidwa ndi makina, nthawi zina polarity imasintha mofulumira kwambiri, zomwe zimapangitsa kuti ma impulses abwerere m'mbuyo ndipo nthawi zina amasintha mochedwa, zomwe zimapangitsa kuti "kuima" nthawi yomweyo kuzungulire. Mulimonse momwe zingakhalire, mavutowa amabweretsa ma current peaks ndi kusakhazikika kwa makina.

Kampani ya Leader Microelectronics (Huizhou) Co., Ltd., yomwe idakhazikitsidwa mu 2007, ndi kampani yapadziko lonse lapansi yomwe imagwiritsa ntchito kafukufuku ndi chitukuko, kupanga ndi kugulitsa. Timapanga zinthu zambiri.mota yathyathyathya, mota yolunjika,Galimoto ya BLDC, mota yopanda coreless, mota ya SMD, mota yopangira ma Air, mota yochepetsera liwiro ndi zina zotero, komanso mota yaying'ono yomwe imagwiritsidwa ntchito m'magawo ambiri.
