AC asynchronous lub cev muaj zog ua haujlwm li cas?

IbAC asynchronous lub cev muaj zogyog ib hom hluav taws xob lub cev muaj zog uas ua haujlwm ntawm alternating tam sim no (AC) lub zog. Nws yog hu ua "asynchronous" vim hais tias qhov ceev ntawm lub cev muaj zog yog me ntsis qeeb dua lub synchronous ceev, uas yog qhov ceev ntawm lub magnetic teb nyob rau hauv lub stator.

AC asynchronous lub cev muaj zog muaj ob ntu: stator thiab rotor. Lub stator yog qhov chaw ruaj khov ntawm lub cev muaj zog uas muaj cov kab sib txuas thiab txuas nrog lub zog hluav taws xob. Lub rotor yog lub rotating ib feem ntawm lub cev muaj zog uas txuas nrog lub load, thiab nws yog tsim los ntawm ib tug series ntawm conductors uas yog teem nyob rau hauv ib tug ncig qauv.

Thaum lub zog siv rau stator windings, ib qho chaw sib nqus sib nqus yog tsim. Qhov no magnetic teb ces induces ib tug electromagnetic teb nyob rau hauv lub rotor windings, uas ua rau lub rotor tig. Kev sib hloov ntawm lub rotor ua rau cov ncej txuas nrog lub rotor tig, uas tom qab ntawd tsav lub nra.

Qhov ceev ntawm AC asynchronous lub cev muaj zog nyob ntawm qhov zaus ntawm AC fais fab mov thiab pes tsawg tus ncej hauv stator. Tus naj npawb ntawm tus ncej yog txiav txim los ntawm tus naj npawb ntawm stator windings thiab kev tsim kho lub cev muaj zog. Qhov ntau ncej ntawm lub cev muaj zog, qhov qeeb qeeb ntawm lub cev muaj zog.

Hauv cov ntsiab lus, AC asynchronous motors ua haujlwm los ntawm kev siv kev sib cuam tshuam ntawm magnetic teb hauv stator thiab rotor los tsim kev sib hloov. Qhov ceev ntawm lub cev muaj zog yog qeeb dua li synchronous ceev thiab txiav txim siab los ntawm qhov zaus ntawm AC fais fab mov thiab tus naj npawb ntawm cov ncej hauv stator.

AC asynchronous motors muaj ntau yam zoo, xws li:

High Efficiency: Lawv ua tau zoo heev thiab tuaj yeem hloov tau qhov feem pua ​​​​ntawm cov hluav taws xob hluav taws xob uas lawv siv rau hauv lub zog siv tshuab.

Simple Structure: Lawv muaj cov qauv yooj yim thiab muaj zog uas ua rau lawv yooj yim rau kev tsim, khiav lag luam thiab tswj.

Kev Kho Mob Tsawg: Lawv muaj ob peb yam khoom siv kho tshuab, ua rau lawv tsis tshua muaj kev ua haujlwm tsis zoo lossis cov teeb meem txij nkawm.

Durable: Lawv yog cov ruaj thiab tuaj yeem ua haujlwm nyob rau hauv ntau qhov kub thiab ib puag ncig.

Tus nqi qis: Lawv kuj yog tus nqi qis dua piv rau lwm hom motors.

Zuag qhia tag nrho, AC asynchronous motors yog ib qho kev txhim khu kev qha thiab raug nqi zoo rau ntau daim ntawv thov. Lawv tau siv dav hauv cov twj tso kua mis, kiv cua, compressors, thiab lwm yam kev lag luam uas yuav tsum muaj lub zog hloov pauv.
