Cov hlau nplaum ruaj khov synchronous lub cev muaj zog yog tsim los ntawm stator, rotor thiab vaj tse. Zoo li cov AC motors zoo tib yam, cov tub ntxhais stator yog cov qauv laminated los txo cov hlau tsis zoo vim yog cov eddy tam sim no thiab hysteresis cuam tshuam thaum lub sijhawm ua haujlwm lub cev muaj zog; cov windings kuj feem ntau yog peb-theem symmetrical qauv, tab sis qhov kev xaiv parameter txawv heev. Lub rotor ib feem muaj ntau yam ntaub ntawv, nrog rau cov hlau nplaum ruaj khov rotors nrog pib squirrel tawb, thiab built-in los yog nto-mounted ntshiab hlau nplaum rotors. Lub rotor core tuaj yeem ua rau hauv cov qauv khoom lossis laminated. Lub rotor yog nruab nrog cov khoom siv hlau nplaum ruaj khov, uas feem ntau hu ua hlau nplaum hlau.
Nyob rau hauv ib txwm ua haujlwm ntawm lub cev muaj zog hlau nplaum ruaj khov, lub rotor thiab stator magnetic teb nyob rau hauv lub xeev synchronous, tsis muaj induced tam sim no nyob rau hauv lub rotor ib feem, tsis muaj rotor tooj liab poob, hysteresis, thiab eddy tam sim no poob, thiab tsis muaj kev xav tau. xav txog qhov teeb meem ntawm rotor poob thiab kev tsim hluav taws xob. Feem ntau, lub cev muaj zog hlau nplaum ruaj khov yog siv los ntawm lub tshuab hloov pauv tshwj xeeb, thiab ib txwm muaj qhov pib muag muag. Tsis tas li ntawd, cov hlau nplaum ruaj khov lub cev muaj zog yog lub cev muaj zog synchronous, uas muaj cov yam ntxwv ntawm kev hloov kho lub zog ntawm lub tshuab synchronous los ntawm lub zog ntawm qhov excitation, yog li lub zog qhov tseem ceeb tuaj yeem tsim rau tus nqi teev.
Los ntawm qhov kev xav ntawm kev pib, vim qhov tseeb tias lub tshuab hlau nplaum ruaj khov yog pib los ntawm qhov sib txawv ntawm cov khoom siv hluav taws xob los yog kev txhawb nqa zaus hloov pauv, cov txheej txheem pib ntawm lub tshuab hlau nplaum ruaj khov yog yooj yim kom paub; zoo ib yam li qhov pib ntawm qhov sib txawv zaus lub cev muaj zog, nws zam qhov pib qhov tsis xws luag ntawm lub tawb zoo tib yam asynchronous lub cev muaj zog.
Hauv luv luv, qhov ua tau zoo thiab lub zog ntawm cov hlau nplaum ruaj khov tuaj yeem ncav cuag siab heev, thiab cov qauv yooj yim heev. Lub khw tau kub heev nyob rau hauv kaum xyoo dhau los.
Txawm li cas los xij, demagnetization tsis ua haujlwm yog ib qho teeb meem uas tsis tuaj yeem zam tau rau cov hlau nplaum ruaj khov. Thaum qhov tam sim no siab dhau los yog qhov kub thiab txias dhau lawm, qhov kub ntawm lub cav windings yuav nce sai sai, tam sim no yuav nce siab, thiab cov hlau nplaum ruaj khov yuav poob lawv cov hlau nplaum sai. Hauv kev tswj xyuas lub cev muaj zog ruaj khov, ib qho khoom siv tiv thaiv overcurrent tau teeb tsa kom tsis txhob muaj teeb meem ntawm lub cev muaj zog stator winding raug hlawv, tab sis qhov ua rau poob ntawm cov hlau nplaum thiab cov cuab yeej kaw yog qhov kev zam.
Piv nrog rau lwm cov motors, daim ntawv thov ntawm cov hlau nplaum ruaj khov motors hauv kev ua lag luam tsis nrov heev. Muaj qee qhov tsis paub txog qhov muag tsis pom kev rau ob qho tib si lub cev muaj zog manufacturers thiab cov neeg siv, tshwj xeeb tshaj yog thaum nws los txog rau kev sib piv nrog cov zaus hloov pauv, uas feem ntau ua rau kev tsim tus nqi yog qhov tsis sib haum nrog cov ntaub ntawv sim thiab yuav tsum tau txheeb xyuas ntau zaus.
