Ib qho hluav taws xob (Lub Cev Tsav Tsheb) yog ib lub tshuab uas hloov cov hluav taws xob ua hluav taws xob rau hauv tshuab hluav taws xob. Nws yog los ntawm hluav taws xob kauj (piv txwv li stator winding) thiab tsim ib lub dav hlau magnetic acting rau lub rotor (xws li tus nas cage kaw txhuas tus ncej) ua magnetoelectric teb torque. Siv lub cav qoj raws li DC motor thiab AC motor, lub cev muaj zog zog hauv feem ntau ntawm AC lub cev muaj peev xwm ua tau synchronous los yog asynchronous lub cev muaj zog (kev tsav lub zog ntawm kev sib tw motor thiab rotor sib nqus ceev kom ceev sib npaug). Lub cev yog tsim los ntawm stator thiab rotor. Cov kev taw qhia ntawm lub zog ntawm cov hlau hauv cov hlau nplaum yog nyob rau ntawm qhov kev taw qhia ntawm qhov tam sim no thiab cov kev taw qhia ntawm cov hlau nplaum ntawm qhov sib nqus (qhov kev taw qhia ntawm cov hlau nplaum). Txoj haujlwm ua haujlwm ntawm kev tsav tsheb yog qhov sib txig sib luag ua rau lub zog ntawm qhov tam sim no, kom lub cav tig.
