I-DC motor iqukethe izingxenye ezimbili eziyinhloko: i-rotor ne-stator. I-rotor ine-toroidal core enezikhala zokubamba amakhoyili noma ama-winding. Ngokomthetho kaFaraday, lapho umgogodla uzungeza endaweni kazibuthe, amandla kagesi noma amandla kagesi afakwa kukhoyili, futhi leli khono likagesi elibangelwayo lizobangela ukugeleza kwamanje, okubizwa ngokuthi i-eddy current.

Ama-Eddy currents awumphumela wokuzungezisa umnyombo phakathiiinsimu kazibuthe

I-Eddy yamanje iwuhlobo lokulahlekelwa kazibuthe, futhi ukulahlekelwa kwamandla ngenxa yokugeleza kwe-eddy yamanje kubizwa ngokuthi ukulahlekelwa kwamanje kwe-eddy. Ukulahlekelwa yi-Hysteresis kungenye ingxenye yokulahlekelwa kazibuthe, futhi lokhu kulahlekelwa kukhiqiza ukushisa futhi kunciphisa ukusebenza kahle kwemoto.

Ukuthuthukiswa kweeI-ddy yamanje ithonywa ukumelana kwezinto zayo ezigelezayo

Kunoma yikuphi okubonakalayo kazibuthe, kukhona ubudlelwano obuphambene phakathi kwendawo yesiphambano sezinto ezibonakalayo kanye nokumelana kwayo, okusho ukuthi indawo encishisiwe iholela ekwandeni kokumelana, okuholela ekunciphiseni kwemisinga eddy. Enye indlela yokunciphisa indawo ephambanayo ukwenza impahla ibe mncane.

Lokhu kuchaza ukuthi kungani i-motor core yenziwe ngamashidi amaningi ensimbi amancane (abizwakagesi motor laminations) kunocezu olulodwa olukhulu noluqinile lwamashidi ensimbi. Lawa mashidi angawodwa anokumelana okuphakeme kuneshidi elilodwa eliqinile, ngakho-ke akhiqiza ukulahlekelwa okuncane kwe-eddy yamanje kanye ne-eddy ephansi yamanje.

Isamba sama-eddy currents kuma- laminated cores sincane kunaleso kuma-cores aqinile

Lezi zitaki ze-lamination zihlanganiswe komunye nomunye, futhi ungqimba lwe-lacquer luvame ukusetshenziselwa ukuvimbela ama-eddy currents "ukweqa" kusuka ku-stack kuya ku-stack. Ubudlelwano besikwele obuphambene phakathi kogqinsi lwempahla nokulahlekelwa kwamanje kwe-eddy kusho ukuthi noma yikuphi ukuncipha kogqinsi kuzoba nomthelela omkhulu enanini lokulahlekelwa. Ngakho-ke, iGator, iChinaimboni ye-rotor eyanelisayo, ilwela ukwenza ama-motor core laminations abe mncane ngangokunokwenzeka ngokombono wokukhiqiza nezindleko, ngamamotho esimanje e-DC ngokuvamile asebenzisa ugqinsi luka-0.1 kuya ku-0.5 mm.

Isiphetho

Indlela yamanje yokulahlekelwa kwe-eddy idinga ukuthi injini ifakwe izingqimba ezivikelayo zezitaki ukuze kuvinjelwe ama-eddy currents "ukweqa" ukusuka kuma-laminations kuye kuma-laminations.
