Nrog rau txoj kev loj hlob sai ntawm lub zog hluav taws xob tshuab hluav taws xob thiab cov khoom siv hluav taws xob tshiab, AC ceev kev tswj hwm thev naus laus zis tau txhim kho thiab txhim kho tsis tu ncua. Cov kev hloov pauv hloov maj mam tau siv dav hauv AC motors nrog nws cov txiaj ntsig zoo thiab cov txiaj ntsig zoo-nqi piv. Piv txwv li: cov motors loj siv rau steel dov hauv steel mills, me me thiab nruab nrab cov menyuam motors, traction motors rau railways thiab nroog rail transit, of elevator motors, hoisting motors for container lifting equipment, motors for water pumps and fans, compressors, motors for home appliances, etc.
Lub axial thiab radial qhov ntev ntawm lub cev muaj zog txiav txim siab nws tag nrho cov tsos. Slender motors thiab luv luv thiab rog motors yuav muaj qee qhov teeb meem hauv kev tsim khoom, thiab cov txheeb ze yuam kev yuav muaj kev cuam tshuam ntau dua rau kev ua haujlwm ntawm lub cev muaj zog. Rau qhov sib txawv zaus motors, qhov tseem ceeb resonance yuav tsum tau txiav txim siab, uas cuam tshuam rau lub cev muaj zog kev ua haujlwm.
Piv nrog rau cov motors muaj zaus, qhov sib txawv zaus motors yuav tsum muaj rotor zoo sib npaug, siab machining raug ntawm cov neeg kho tshuab qhov chaw, thiab tshwj xeeb high-precision bearings los xyuas kom meej tias kev vibration kev ua tau zoo nyob rau hauv high-ceev ua hauj lwm raws li qhov yuav tsum tau. Txog rau qhov kawg no, axial ntev ntawm lub cev muaj zog sib txawv yuav tsum tau tswj kom tsis txhob muaj lub hom phiaj ntawm kev kub ceev kev co tshwm sim los ntawm qhov ntev axial loj. Cov neeg siv khoom uas tau siv lub tshuab hluav taws xob sib txawv tuaj yeem paub tias feem ntau, kev vibration hnyav yuav tshwm sim hauv qee qhov zaus, tshwj xeeb tshaj yog thaum qhov kev hloov pauv ntau zaus. Qhov no yog qhov peb hu ua resonance. Resonance tseem hu ua "resonance". Nws yog qhov tshwm sim uas lub amplitude ntawm lub oscillation system nce sharply thaum lub zaus ntawm lub sab nraud quab yuam yog tib yam li los yog heev ze rau lub ntuj oscillation zaus ntawm lub system nyob rau hauv qhov kev txiav txim ntawm periodic sab nraud quab yuam. Qhov zaus thaum resonance tshwm sim yog hu ua "resonance zaus".
Xav txog qhov tseeb tias lub cev muaj zog muaj zog muaj zog thiab ntau yam kev tswj xyuas ceev, kev tsim cov hlau nplaum sib nqus ntawm cov motors sib txawv yuav tsum tau ua kom zoo dua ntxiv los txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm Tshwj xeeb, kev xaiv cov zaus hloov pauv yuav tsum tau ua ke nrog cov kev ua haujlwm tiag tiag thiab sib tw nrog cov khoom siv hluav taws xob zoo tsim nyog.
