Ua hauj lwm hauv paus ntsiab lus ntawm txhuam DC lub cev muaj zog

Muaj cov hlau nplaum nyob rau hauv qhov chaw ruaj khov ntawm lub tshuab DC brushed, ntawm no hu ua lub ntsiab sib nqus ncej; tseem muaj cov txhuam hniav hauv qhov chaw ruaj khov. Lub rotating ib feem muaj annular hlau core thiab windings raug mob nyob ib ncig ntawm lub annular hlau core.

Ib khub ntawm lub ntsiab sib nqus ncej N thiab S ntawm DC excitation yog ntsia rau ntawm qhov chaw ruaj khov (stator) ntawm ob-ncej brushed DC lub cev muaj zog, thiab cov tub ntxhais armature yog ntsia rau ntawm qhov tig (rotor). Muaj qhov sib txawv ntawm huab cua ntawm stator thiab rotor. Lub armature coil yog muab tso rau ntawm lub tub ntxhais armature, uas txuas nrog ob tus neeg xyuas pib A thiab X. Lub taub hau thiab qhov kawg ntawm lub kauj yog txuas nrog ob daim ntawv tooj liab arc, uas yog hu ua commutation segments. Cov commutator ntu yog insulated los ntawm ib leeg, thiab tag nrho cov tsim ntawm cov commutator ntu yog hu ua commutator. Lub commutator yog tsau rau ntawm lub rotating ncej, thiab lub commutator daim thiab lub rotating ncej kuj insulated ntawm ib leeg. Ib khub ntawm cov txhuam hniav nyob ruaj ruaj yog muab tso rau ntawm ntu commutator. Thaum lub armature rotates, lub armature coil txuas nrog rau sab nraud Circuit Court los ntawm commutator ntu thiab txhuam.
