DC lub cev muaj zog muaj ob yam tseem ceeb: lub rotor thiab stator. Lub rotor muaj ib tug toroidal core nrog slots rau tuav lub coils los yog windings. Raws li Faraday txoj cai lij choj, thaum cov tub ntxhais tig mus rau hauv qhov chaw sib nqus, qhov hluav taws xob lossis hluav taws xob muaj peev xwm raug cuam tshuam rau hauv lub kauj, thiab qhov kev cuam tshuam hluav taws xob no yuav ua rau cov dej ntws tam sim no, hu ua eddy tam sim no.

Eddy tam sim no yog qhov tshwm sim ntawm kev sib hloov ntawm cov tub ntxhais hauvtusmagnetic teb

Eddy tam sim no yog ib hom kev sib nqus, thiab lub zog poob vim qhov ntws ntawm eddy tam sim no hu ua eddy tam sim no poob. Hysteresis poob yog lwm yam kev sib nqus poob, thiab cov kev poob no ua kom sov thiab txo qhov ua haujlwm ntawm lub cev muaj zog.

Kev loj hlob ntawmeddy tam sim no cuam tshuam los ntawm qhov tsis kam ntawm nws cov khoom ntws

Rau txhua yam khoom siv hlau nplaum, muaj qhov sib txawv ntawm qhov sib txawv ntawm thaj tsam ntawm cov khoom siv thiab nws qhov kev tiv thaiv, uas txhais tau hais tias qhov chaw txo qis ua rau muaj kev tawm tsam, uas ua rau muaj qhov txo qis hauv eddy tam sim no. Ib txoj hauv kev los txo qhov ntu ntu ntu yog ua kom cov khoom nyias nyias.

Qhov no piav qhia vim li cas lub cev muaj zog yog ua los ntawm ntau cov ntawv hlau nyias (hu uahluav taws xob laminations) es tsis yog ib qho loj thiab khoom ntawm cov ntawv hlau. Cov nplooj ntawv ib tus neeg no muaj kev tiv thaiv siab dua li ib daim ntawv, thiab yog li tsim cov eddy tam sim no thiab qis dua tam sim no poob.

Cov eddy tam sim no nyob rau hauv lub laminated cores yog tsawg tshaj li nyob rau hauv cov khoom cores

Cov lamination stacks no yog insulated los ntawm ib leeg, thiab ib txheej ntawm lacquer feem ntau yog siv los tiv thaiv eddy tam sim no "dhia" los ntawm pawg rau pawg. Qhov kev sib raug zoo ntawm cov square ntawm cov khoom thickness thiab eddy tam sim no poob txhais tau hais tias ib qho kev txo qis hauv thickness yuav muaj qhov cuam tshuam loj rau qhov poob. Yog li ntawd, Gator, ib tug Suavtxaus siab rotor Hoobkas, sib zog ua kom lub cev muaj zog laminations nyias raws li qhov ua tau los ntawm qhov kev xav ntawm kev tsim khoom thiab cov nqi, nrog rau niaj hnub DC motors feem ntau siv laminations ntawm 0.1 txog 0.5 hli tuab.

Lub eddy tam sim no poob mechanism yuav tsum tau lub cev muaj zog yuav tsum tau stacked nrog insulating txheej ntawm stacks los tiv thaiv eddy tam sim no "dhia" los ntawm laminations rau laminations.
