Qhov sib txawv ntawm asynchronous thiab synchronous motors

Asynchronous motors thiab synchronous motors yog ob hom hluav taws xob motors uas tau siv dav hauv kev lag luam thiab kev lag luam. Txawm hais tias lawv yog tag nrho cov cuab yeej siv los hloov hluav taws xob rau hauv lub zog siv tshuab, lawv txawv heev ntawm cov qauv kev ua haujlwm, cov qauv thiab kev siv. Qhov sib txawv ntawm asynchronous motors thiab synchronous motors yuav qhia hauv qab no.

 

Qhov sib txawv ntawm asynchronous thiab synchronous motors

1. Lub hauv paus ntsiab lus ua haujlwm:
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub tshuab asynchronous yog ua raws li lub hauv paus ntsiab lus ua haujlwm ntawm lub tshuab induction. Thaum lub rotor ntawm lub asynchronous lub cev muaj zog cuam tshuam los ntawm ib tug rotating magnetic teb, induced tam sim no yog generated nyob rau hauv lub induction motor, uas generates torque, ua rau lub rotor pib tig. Qhov induced tam sim no yog tshwm sim los ntawm qhov kev sib txheeb ntawm lub rotor thiab lub rotating magnetic teb. Yog li ntawd, lub rotor ceev ntawm lub asynchronous lub cev muaj zog yuav ib txwm qis dua qhov ceev ntawm lub rotating magnetic teb, uas yog vim li cas nws thiaj li hu ua "asynchronous" lub cev muaj zog.
Lub hauv paus ntsiab lus ua haujlwm ntawm synchronous lub cev muaj zog yog ua raws li lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm synchronous lub cev muaj zog. Lub rotor ceev ntawm lub tshuab synchronous yog raws nraim synchronized nrog qhov ceev ntawm lub rotating magnetic teb, li no lub npe "synchronous" lub cev muaj zog. Synchronous motors tsim ib tug rotating magnetic teb los ntawm alternating tam sim no synchronized nrog ib tug sab nraud fais fab mov, thiaj li hais tias lub rotor kuj yuav tig synchronously. Synchronous motors feem ntau xav tau cov khoom siv sab nraud kom lub rotor synchronized nrog lub rotating magnetic teb, xws li teb tam sim no lossis cov hlau nplaum ruaj khov.

2. Cov yam ntxwv zoo:
Cov qauv ntawm lub tshuab asynchronous yog qhov yooj yim thiab feem ntau muaj stator thiab rotor. Muaj peb lub windings ntawm lub stator uas yog hluav taws xob hloov los ntawm 120 degrees los ntawm ib leeg los tsim ib qho chaw sib nqus sib nqus los ntawm kev hloov tam sim no. Nyob rau hauv lub rotor feem ntau yog ib tug yooj yim tooj liab conductor qauv uas induces ib tug rotating magnetic teb thiab tsim torque.
Cov qauv ntawm synchronous lub cev muaj zog yog qhov nyuaj, feem ntau suav nrog stator, rotor thiab excitation system. Lub tshuab excitation tuaj yeem yog DC lub zog los yog cov hlau nplaum ruaj khov, siv los ua kom muaj qhov sib nqus sib nqus. Tseem muaj feem ntau windings ntawm lub rotor kom tau txais cov magnetic teb generated los ntawm excitation system thiab tsim torque.

3. Cov yam ntxwv ceev:
Txij li thaum lub rotor ceev ntawm lub asynchronous lub cev muaj zog yog ib txwm qis dua qhov ceev ntawm rotating magnetic teb, nws ceev hloov nrog qhov loj ntawm lub load. Nyob rau hauv rated load, nws ceev yuav qis me ntsis tshaj qhov ntsuas ceev.
Lub rotor ceev ntawm lub synchronous lub cev muaj zog yog synchronized tag nrho nrog rau qhov ceev ntawm rotating magnetic teb, yog li nws ceev yog tas li thiab tsis cuam tshuam los ntawm lub load loj. Qhov no muab cov motors synchronous kom zoo dua hauv cov ntawv thov uas yuav tsum tau tswj ceev ceev.

4. Tswj txoj kev:
Txij li thaum qhov ceev ntawm lub asynchronous lub cev muaj zog cuam tshuam los ntawm kev thauj khoom, cov cuab yeej tswj xyuas ntxiv feem ntau yuav tsum ua kom tiav kev tswj ceev ceev. Cov kev tswj hwm feem ntau suav nrog kev hloov pauv ceev ceev thiab pib muag.
Synchronous motors muaj qhov ceev tsis tu ncua, yog li kev tswj tau yooj yim. Kev tswj ceev tuaj yeem ua tiav los ntawm kev kho qhov excitation tam sim no lossis lub zog sib nqus ntawm cov hlau nplaum ruaj khov.

5. Kev siv thaj chaw:
Vim nws cov qauv yooj yim, tus nqi qis, thiab tsim nyog rau kev siv lub zog siab thiab lub zog siab, asynchronous motors tau siv dav hauv kev lag luam, xws li cua zog tsim, twj, kiv cua, thiab lwm yam.
Vim nws qhov ceev ceev thiab muaj zog meej tswj muaj peev xwm, synchronous motors yog tsim rau cov kev siv uas yuav tsum tau ceev ceev tswj, xws li generators, compressors, conveyor siv, thiab lwm yam nyob rau hauv lub hwj chim systems.

Feem ntau, asynchronous motors thiab synchronous motors muaj qhov sib txawv hauv lawv cov qauv kev ua haujlwm, cov yam ntxwv ntawm cov qauv, ceev cov yam ntxwv, kev tswj cov txheej txheem thiab daim ntawv thov. Kev nkag siab txog qhov sib txawv no tuaj yeem pab xaiv hom lub cev muaj zog kom tau raws li cov kev xav tau tshwj xeeb engineering.
