Tshaj qhov loj me, synchronous motors tsis yog tus kheej pib motors. Cov cuab yeej no yog vim lub inertia ntawm lub rotor; Nws tsis tuaj yeem ua raws li qhov kev sib hloov ntawm cov magnetic teb ntawm stator. … Thaum lub rotor nyob ze ntawm lub synchronous ceev, lub teb winding zoo siab, thiab lub cev muaj zog rub mus rau hauv synchronization.
Lub cev muaj zog synchronous pib li cas?
Lub cev muaj zog yog thawj zaug as lub nplhaib ntiv nplhaib induction lub cev muaj zog. Qhov kev tiv thaiv yog maj mam txiav tawm raws li lub cev muaj zog nce ceev. Thaum nws ua tiav nyob ze synchronous ceev, DC excitation yog muab rau lub rotor, thiab nws yog rub mus rau hauv synchronism. Tom qab ntawd nws pib tig raws li lub tshuab synchronous.
Lub cev muaj zog twg yog tus kheej pib?
Peb-theem induction lub cev muaj zog yog pib nws tus kheej, vim tias winding hloov pauv yog 120 degrees rau txhua theem thiab cov khoom siv kuj muaj 120 theem ua haujlwm rau 3-theem. Nws ua rau lub unidirectional rotating magnetic teb yog tsim nyob rau hauv huab cua sib txawv uas ua rau 3-theem induction lub cev muaj zog rau nws tus kheej pib.
Yuav ua li cas synchronous lub cev muaj zog ua tus kheej pib?
Lub tshuab synchronous yog ua rau nws tus kheej pib los ntawm muab qhov tshwj xeeb winding ntawm rotor ncej, hu ua damper winding lossis squirrel tawb winding. AC muab rau tus stator ua rau lub rotating magnetic teb uas ua rau lub rotor tig.
Nws tsis yog lub cav pib tus kheej?
Peb tuaj yeem xaus lus yooj yim tias ib-theem induction motorstsis yog tus kheej-pib vim hais tias cov tsim stator flux yog alternating nyob rau hauv cov xwm thiab thaum pib, ob lub Cheebtsam ntawm no flux tshem tawm ib leeg, thiab li no tsis muaj net torque.
