Kev hloov pauv ntawm qhov qis- nrawm thiab siab- ceev fais fab mov hom thaum lub sijhawm ua haujlwm yog tsis siv neeg, tsis tas yuav muaj cov khoom siv hluav taws xob ntxiv. Lub hauv paus ntsiab lus ua haujlwm tau txheeb xyuas raws li hauv qab no:
Hauv qhov qis- nrawm nrawm, vim lub tshuab hluav taws xob tsis tshua muaj kev sib hloov ceev, kev sib txuas ntawm peb -theem windings boosts cov zis hluav taws xob, yog li ua kom lub tshuab hluav taws xob ua haujlwm tau zoo ntawm qhov qis qis. Nyob rau hauv qhov siab -ceev ntau, raws li lub tshuab hluav taws xob qhov kev sib hloov ceev nce, qhov inductive reactance ntawm koob- txuas peb-theem windings nce, ua rau muaj qhov nce hauv qhov hluav taws xob poob; Tsis tas li ntawd, qhov intensified armature cov tshuaj tiv thaiv ua rau cov zis voltage poob. Nyob rau theem no, thawj peb -theem windings (A, B, thiab C)-tus yam ntxwv los ntawm qhov tsawg dua qhov hluav taws xob sab hauv poob- ua kom muaj qhov sib piv siab dua tam sim no, yog li ua kom lub zog muaj zog ntawm kev kub ceev.
