Lub cev muaj zog induction yog lub tshuab hluav taws xob uas ua haujlwm raws li lub hauv paus ntsiab lus ntawm electromagnetic induction. Nws yog lub cev muaj zog uas tsis muaj kev sib cuag hauv lub tshuab, yog li nws muaj qhov zoo ntawm kev ntseeg siab, tsis tshua muaj suab nrov, thiab kev saib xyuas yooj yim. Nws yog dav siv nyob rau hauv ntau yam mechanical systems.
Induction motor muaj ob ntu: rotor thiab stator. Lub rotor feem ntau muaj cov kiv cua-zoo li tus qauv ntawm tooj liab tuav, thiab lub stator muaj coils uas txuas nrog lub hwj chim mov. Thaum tam sim no ntws los ntawm stator coil, ib qho chaw sib nqus yuav raug tsim tawm. Qhov no magnetic teb yuav nkag mus rau lub tooj liab bar thiab ua rau ib tug induced tam sim no nyob rau hauv lub tooj liab bar. Lub magnetic teb generated los ntawm qhov induced tam sim no cuam tshuam nrog stator magnetic teb, ua rau lub rotor tig. Feem ntau, tus naj npawb ntawm cov hlau nplaum ntawm cov coils ntawm lub stator yog ib qho tseem ceeb ntawm cov xov tooj ntawm cov hlau nplaum ntawm cov rotor tooj liab strips, uas ua kom ntseeg tau tias qhov zaus ntawm rotor kev sib hloov yog synchronized nrog zaus ntawm cov khoom siv fais fab.
Tag nrho cov txheej txheem tuaj yeem muab faib ua peb theem: peb-theem alternating tam sim no yog cov tswv yim rau lub coil terminals ntawm stator los ua kom muaj qhov sib nqus sib nqus (piv txwv li, qhov chaw sib nqus ruaj khov). Qhov chaw sib nqus ruaj khov no ua rau muaj qhov cuam tshuam tam sim no hauv lub rotor, ua rau muaj qhov sib nqus (piv txwv li, rotating magnetic field) tsim nyob rau hauv lub rotor. Qhov no magnetic teb cuam tshuam nrog cov hlau nplaum ruaj khov, ua rau lub rotor tig, thiab thaum kawg mus txog lub xeev ua haujlwm ruaj khov.
Qhov zoo ntawm induction motors yog lawv cov qauv yooj yim, muaj kev ntseeg siab, kev pab lub neej ntev, thiab qhov tseeb tias lawv tsis muaj cov khoom sib txuas uas yuav tsum tau saib xyuas. Nws txuag hluav taws xob ntau dua li lwm lub tshuab hluav taws xob, txo cov theem simulation thiab txo qhov kev pheej hmoo ntawm kev ua tsis tiav. Nws muaj lub zog pib siab thiab kev hloov kho dav dav, uas tuaj yeem ua tau raws li kev siv sib txawv.
Induction motors yog tam sim no dav siv nyob rau hauv ntau yam teb, xws li kis tau tus mob machinery, industrial ntau lawm khoom, khoom siv hauv tsev, automotive teb thiab lwm yam teb. Nws kuj yog ib qho tseem ceeb ntawm kev tsav tsheb hauv tsheb tshiab, uas tuaj yeem txhim kho kev lag luam thiab ib puag ncig kev ua haujlwm ntawm lub tsheb.
Nyob rau hauv luv luv, lub induction lub cev muaj zog yog ib tug zoo heev lub cev muaj zog nrog ib tug yooj yim thiab txhim khu kev qha qauv uas muaj peev xwm ua tau raws li ntau yam kev xav tau kev pab. Nws qhov kev khiav hauj lwm ceev thiab lub zog tuaj yeem ua tiav los ntawm kev kho cov khoom siv hluav taws xob thiab cov qauv rotor. Nyob rau hauv lub neej yav tom ntej, induction motors xav tias yuav dhau los ua cov cuab yeej siv hauv tib neeg lub neej txhua hnub, coj tau yooj yim dua, ib puag ncig tus phooj ywg, thiab siv tau zoo.
