Lub cev muaj zog sib nqus tas mus li feem ntau yog tsim los ntawm stator, rotor thiab cov khoom vaj khoom tsev. Zoo ib yam li cov cav AC ib txwm muaj, lub stator core yog ua los ntawm cov qauv laminated los txo cov hlau poob los ntawm eddy tam sim no thiab hysteresis nyhuv thaum lub sijhawm ua haujlwm ntawm lub cev muaj zog; cov windings feem ntau yog peb-theem symmetrical qauv, tab sis kev xaiv parameter txawv heev. Lub rotor ib feem muaj ntau yam duab, suav nrog lub rotor magnet tas mus li nrog lub tawb pib, nrog rau lub rotor magnet tas mus li uas tau muab tso rau hauv lossis ntsia rau saum npoo. Lub rotor core tuaj yeem ua los ntawm cov qauv khov kho lossis cov qauv laminated. Lub rotor yog nruab nrog cov khoom siv hlau nplaum tas mus li, uas feem ntau hu ua hlau nplaum.
Nyob rau hauv kev ua haujlwm ib txwm ntawm lub cev muaj zog hlau nplaum tas mus li, lub rotor thiab stator magnetic teb yog nyob rau hauv lub xeev synchronous. Tsis muaj induced tam sim no nyob rau hauv lub rotor ib feem, thiab yog li ntawd tsis muaj rotor tooj liab poob lossis hysteresis thiab eddy tam sim no poob. Tsis tas yuav xav txog qhov teeb meem tsim cua sov los ntawm rotor poob. Feem ntau, cov hlau nplaum tas mus li motors yog powered los ntawm tshwj xeeb zaus converters, uas inherently muaj soft-starting functions. Tsis tas li ntawd, cov hlau nplaum tas mus li motors yog synchronous motors thiab muaj tus yam ntxwv ntawm synchronous motors uas lub zog factor tuaj yeem hloov kho rau tus nqi teev tseg los ntawm lub zog ntawm excitation. Yog li ntawd, lub zog factor tuaj yeem tsim rau tus nqi xav tau.
Los ntawm qhov kev xav ntawm kev pib, vim yog qhov xwm txheej tiag tiag uas cov hlau nplaum tas mus li tau pib los ntawm cov khoom siv hluav taws xob hloov pauv zaus lossis cov hloov pauv zaus sib phim, cov txheej txheem pib ntawm cov hlau nplaum tas mus li yog qhov yooj yim heev rau kev ua tiav; zoo ib yam li kev pib ntawm cov cav hloov pauv zaus, nws zam qhov tsis zoo pib ntawm cov cav asynchronous squirrel-cage ib txwm muaj.
Xaus lus, qhov ua tau zoo thiab lub zog ntawm cov cav hlau nplaum tas mus li tuaj yeem ncav cuag cov theem siab heev. Lawv cov qauv yooj yim heev thiab lawv tau nrov heev hauv kev ua lag luam hauv kaum xyoo dhau los. Txawm li cas los xij, qhov tsis zoo ntawm demagnetization yog qhov teeb meem tsis zam rau cov cav hlau nplaum tas mus li. Thaum tam sim no loj dhau lossis qhov kub siab dhau, qhov kub ntawm lub cav winding yuav nce siab sai sai, tam sim no yuav nce siab, thiab lub hlau nplaum tas mus li yuav demagnetize sai sai. Hauv kev tswj hwm ntawm cov cav hlau nplaum tas mus li, lub cuab yeej tiv thaiv overcurrent tau teeb tsa kom tsis txhob muaj teeb meem ntawm stator winding ntawm lub cev muaj zog raug hlawv tawm. Txawm li cas los xij, qhov no ua rau demagnetization thiab cov khoom siv kaw.
