Cob phum hlau npliag (synchronous)
Piv nrog rau cov pa roj carbon monoxide synchronous, lub nro hlau npliag lub tshuab synchronous tsis muaj qhov excitation winding thiab hloov los ntawm ib qho chaw ruaj khov, thiab lub stator cov qauv ntawm ob yog yeej zoo li qub, yog li ntawd txhuam, lub teb winding thiab lub ris hauv ncoo tshem tawm tib lub sijhawm. Lub nplhaib tseem ua kom yooj yim rau cov qauv ntawm lub cav, ua kom yooj yim thiab ntau txhim khu kev qha.
Cov ntsiab cai ua haujlwm pib nrog txoj haujlwm ua haujlwm ntawm kev siv hluav taws xob ua kom muaj zog hauv kev sib txuas lus.
Synchronous motors yog muaj nyob rau hauv ob qho tib si rotate thiab rotating armature versions. Vim hais tias qhov sib txuam magnetic pole yam muaj qhov zoo ntawm qhov me me rotor, yooj yim tsim txoj kev, thiab me me tam sim no los ntawm txhuam thiab nplhaib, lub loj thiab nruab nrab muaj peev xwm synchronous motor feem ntau adopts ib tug tig magnetic ncej hom qauv.
Raws li cov duab ntawm lub rotor, lub cav tig magnetic yuav raug muab faib ua ob hom: cov qauv pole yam thiab nraim ncej hom, raws li qhia hauv daim duab nram qab no. Cov zis tuaj yeem siv rau hauv cov ntawv thov uas yuav tsum tau qis qis dua.

Schematic daim duab ntawm lub tshuab synchronous
Synchronous motors, zoo li lwm yam tshuab cav, muaj ob seem, tus stator thiab cov rotor. Lub stator ntawm lub tshuab synchronous yog tsuas yog tsim los ntawm lub hauv paus, ib qho tseem ceeb thiab ib tus qauv ntawm tus qauv.
Yuav kom txo tau qhov qis thiab zais zuag zuag, qhov tseem ceeb ntawm cov stator stacked nrog nyias silicon steel los xij, thiab sab hauv ntawm sab stator tub ntxhais yog kos nrog ib qho kev sib txig ntawm peb lub theem cua.
Lub rotor yog tsuas yog tsim los ntawm ib tug tig ncej, lub nplhaib khov, ib qho tseem ceeb thiab rotor winding. Yuav kom ua tau raws li txoj cai ntawm kev sib nqus permeability thiab txhua yam kev ua tau zoo, cov rotor ntxhais feem ntau forged los ntawm high-lub zog alloy hlau.
Thaum lub tshuab synchronous ua haujlwm, ib theem peb theem tam sim no yog nkag mus rau hauv peb-theem winding ntawm tus stator, thiab ib tug ncaj qha tam sim no yog siv rau qhov exciting winding ntawm rotor.
Thaum peb theem tam sim no kis tau los ntawm stator peb-theem symmetrical winding, ib qho kev sib hloov magnetic yog generated hauv cov pa nruab nrab. Qhov ntxig magnetic thaj no tshwm sim thiab yog raws nraim tib yam li lub tshuab qub asynchronous.
Thaum ib tug ncaj qha tam sim no yog siv rau rotor teb winding, lub teb chaws zoo li magnetic ntawm cov polarity tas li. Yog hais tias cov naj npawb ntawm hlau sib nqus ntawm cov rotor magnetic field sib npaug sib npaug sib npaug ntawm cov sib txig sib txig ntawm cov stator magnetic field, rotor magnetic field yog synchronously rotated los ntawm stator rotating magnetic field vim lub dag lub zog ntawm lub stator magnetic teb, uas yog, lub rotor rotates ntawm kev ceev thiab kev coj sib npaug zos rau qhov kev sib hloov magnetic, uas yog ib lub tshuab synchronous. Qhov kev ua hauj lwm yooj yim.
Qhov tig magnetic teb ntawm tus stator los yog cov kev taw qhia ntawm kev hloov ntawm lub rotor yog txiav txim siab los ntawm theem theem ntawm peb theem tam sim no ntws mus rau hauv stator winding. Hloov cov theem zuj zus hloov cov kev taw qhia ntawm kev sib tw ntawm lub tshuab synchronous.
