Raws li kev siv yuav tsum muab faib: tsav kev siv fais fab kev noj haus thiab kev tswj fais fab.
1 tsav lub cev muaj peev xwm raug faib: cov cuab yeej siv hluav taws xob (xws li cov ntawv drilling, polishing, sib tsoo, nplawm, txiav, reaming thiab lwm yam cuab yeej) cov khoom siv fais fab, cov khoom siv hauv tsev (xws li cav ntxuav muag, cua txias, cov cua txias, cov twj, cov VCRs, DVD players , cov tshuab nqus tsev, cov koob yees duab, cov tshuab daus, Cov tshuab hluav taws xob, lwm yam khoom siv) cov cuab yeej siv thiab lwm yam khoom siv me me xwb (nrog rau ntau yam cuab yeej me me, cov khoom me me, cov khoom kho mob, cov khoom siv hluav taws xob, thiab lwm yam).
2 tswj kev tsav yog muab faib ua: kev tsav tsheb thiab kev tsav tsheb.
5. Raws li tus qauv ntawm lub rotor yuav muab faib: cage-type Induction motor (lub qub qauv hu ua tus cwjpwm-cage asynchronous tsav) thiab winding rotor induction motor (lub qub qauv hu ua winding asynchronous tsav).
6. Raws li kev khiav hauj lwm ceev tau muab faib ua ke: kev kub ceev, kev tsav tsheb qis qis, kev khiav ceev ceev, kev tswj kev tsav tsheb. Tsawg-cav qev yog muab faib rau lub iav reducer motor, electromagnetic deceleration motor, torque motor thiab claw ncej synchronous lub cev.
Tsav tsheb ceev tau muab faib ua ib lub tsheb ceev ceev, tsis muaj qhov sib nrhav ceev qis, tsis paub sibtshav sib tw thiab tsis muaj kev sib tw tsis muaj zog, tiam sis tseem muab faib tau rau hauv electromagnetic ceev tswj lub cev, DC ceev regulating lub cev, PWM ntau zaus ceev ceev regulating lub cev muaj zog thiab hloov maj nrawm tsheb.
Lub rotor ceev ntawm ib qho asynchronous lub cev yog ib txwm qis me tshaj li qhov ntawm cov qhov sib hloov magnetic.
Rotor ceev ntawm lub tshuab synchronous yog ywj siab ntawm qhov luaj li cas thiab yog ib txwm cia nyob rau hauv synchronous ceev.
