Thaum hluav taws xob raug siv rau cov hlau nplaum hauv lub armature, ib qho chaw sib nqus yog tsim uas nyiam thiab ua rau cov hlau nplaum hauv stator. Lub armature rotates nyob rau hauv ib tug 180-degree voj voog. Yuav kom tswj tau cov electromagnet spinning, cov ncej yuav tsum tau hloov pauv. Cov txhuam hniav yog tus saib xyuas ntawm kev hloov pauv polarity. Lawv ua kev sib cuag nrog lub armature ob rotating electrodes. Qhov sib nqus polarity ntawm electromagnet yog thim rov qab thaum nws tig.
Los ntawm kev kho cov kev khiav hauj lwm voltage los yog qhov kev siv ntawm lub magnetic teb, qhov ceev thiab torque yuav raug kho kom muab ib tug tas li ceev los yog ib tug ceev uas yog inversely proportional rau cov neeg kho tshuab load. (Tus maub los xa cov pulses tam sim no mus rau lub cev muaj zog windings, uas tswj xyuas lub cev muaj zog thiab lub zog.)
Hluav taws xob propulsion, cranes, ntawv tshuab, thiab steel dov mills txhua tus ntiav Brushed Motors. Brushed motors yuav poob luv thaum xav tau torque loj. Txhuam txhuam kev sib txhuam nce raws li kev ceev nce, thiab siv tau torque txo.
