Txoj Cai Ua Haujlwm ntawm DC Tsav

Lub nplhaib ruaj khov hlau nplaum yog tsau hauv DC lub cev muaj zog. Tam sim no generates ampere quab yuam los ntawm lub kauj ntawm lub rotor. Thaum lub coil ntawm lub rotor nyob rau hauv parallel mus rau magnetic teb, cov kev taw qhia ntawm lub magnetic teb yuav hloov. Yog li ntawd, nyob rau lub sij hawm no, txhuam ntawm qhov kawg ntawm lub rotor tiv tauj nrog lub phaj hloov pauv hloov, yog li cov kev taw qhia ntawm tam sim no ntawm lub kauj yuav hloov, thiab cov kev taw qhia ntawm Lorentz quab yuam generated yuav tsis hloov, yog li lub cev muaj zog tuaj yeem hloov. tig nyob rau hauv ib txoj kev.

Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm DC lub tshuab hluav taws xob yog qhov hloov hluav taws xob hluav taws xob uas cuam tshuam rau hauv lub tshuab hluav taws xob hloov pauv mus rau DC electromotive quab yuam thaum nws raug coj tawm ntawm txhuam kawg los ntawm commutator hauv kev koom tes nrog kev sib hloov ntawm txhuam.

Cov kev taw qhia ntawm induced electromotive quab yuam yuav tsum tau txiav txim raws li txoj cai txoj cai (cov magnetic induction kab taw qhia rau lub xib teg ntawm tes, tus ntiv tes xoo taw tes rau lub txav ntawm tus neeg xyuas pib, thiab cov kev taw qhia ntawm lwm plaub ntiv tes yog cov kev taw qhia ntawm induced electromotive quab yuam nyob rau hauv tus neeg xyuas pib).

Kev taw qhia ntawm lub zog ntawm tus neeg xyuas pib yog txiav txim siab los ntawm txoj cai sab laug. Ob khub ntawm electromagnetic rog tsim ib lub zog ua haujlwm ntawm lub armature, uas yog hu ua electromagnetic torque nyob rau hauv rotating hluav taws xob tshuab. Cov kev taw qhia ntawm lub torque yog counterclockwise, sim ua kom lub armature tig counterclockwise. Yog tias qhov hluav taws xob hluav taws xob no tuaj yeem kov yeej qhov kev tawm tsam ntawm lub armature (xws li kev tiv thaiv torque los ntawm kev sib txhuam thiab lwm yam load torques), lub armature tuaj yeem tig mus rau hauv kev coj ua counterclockwise.
