Chifukwa chiyani DC Motor Core Imapangidwa Ndi Laminations

Galimoto ya DC imakhala ndi zigawo ziwiri zazikulu: rotor ndi stator. Rotor ili ndi pakatikati pa toroidal yokhala ndi mipata yogwirizira ma coils kapena ma windings. Malinga ndi lamulo la Faraday, pachimake pakatikati pa maginito, mphamvu yamagetsi kapena mphamvu yamagetsi imapangidwira mu koyilo, ndipo mphamvu yamagetsi yomwe imapangitsa kuti izi zitheke zingayambitse kutuluka kwamakono, komwe kumatchedwa eddy current.

Mafunde a Eddy ndi chifukwa cha kuzungulira kwapakati mkatindimaginito

Eddy current ndi mtundu wa kutayika kwa maginito, ndipo kutaya mphamvu chifukwa cha kutuluka kwa eddy current kumatchedwa eddy current loss. Kutayika kwa Hysteresis ndi gawo lina la kuwonongeka kwa maginito, ndipo zotayika izi zimatulutsa kutentha ndikuchepetsa mphamvu ya injini.

Kukula kwaeddy pano amakhudzidwa ndi kukana kwa zinthu zake zoyenda

Pazinthu zilizonse za maginito, pali mgwirizano wotsutsana pakati pa gawo la gawo la zinthuzo ndi kukana kwake, zomwe zikutanthauza kuti dera lochepa limayambitsa kuwonjezeka kwa kukana, komwe kumayambitsa kuchepa kwa mafunde a eddy. Njira imodzi yochepetsera chigawo chapakati ndikupangitsa kuti zinthuzo zikhale zowonda kwambiri.

Izi zikufotokozera chifukwa chake pakatikati pa injiniyo amapangidwa ndi zitsulo zambiri zopyapyala (zotchedwamagetsi opangira magetsi) osati chitsulo chimodzi chachikulu komanso cholimba. Mapepala awa ali ndi kukana kwakukulu kuposa pepala limodzi lolimba, motero amatulutsa zotayika zochepa za eddy panopa komanso zotsika za eddy panopa.

Kuchuluka kwa mafunde a eddy m'magulu a laminated ndi ochepa kuposa omwe ali muzitsulo zolimba

Milu ya lamination iyi imayikidwa pakati pa wina ndi mzake, ndipo wosanjikiza wa lacquer nthawi zambiri amagwiritsidwa ntchito kuteteza mafunde a eddy "kulumpha" kuchokera ku stack kupita ku stack. Ubale wosiyana pakati pa makulidwe a zinthu ndi kutayika kwa eddy panopa kumatanthauza kuti kuchepa kulikonse kwa makulidwe kudzakhala ndi zotsatira zazikulu pa kuchuluka kwa kutayika. Chifukwa chake, Gator, waku Chinafakitale yokwanira ya rotor, imayesetsa kupangitsa kuti magetsi azing'onoting'ono azing'onoting'ono momwe angathere malinga ndi momwe amapangira komanso mtengo wake, ndi ma motor amakono a DC omwe amagwiritsa ntchito ma lamination a 0.1 mpaka 0.5 mm.

Mapeto

Makina otayika amakono amafunikira kuti injiniyo isanjidwe ndi miyandamiyanda yotsekera kuti mafunde a eddy "adumphe" kuchoka pamiyendo kupita ku zoyala.
