Tsis siv neeg lub tshuab nqus tsev ntim cov yam ntxwv yooj yim yog lub cev muaj zog ntawm cov txheej txheem electromagnetic dhia, pulse voltage nyob rau hauv lem ntawm kev tswj sib txawv winding, lub cev muaj zog yog tsis sib npaug ntawm qhov chaw nyob rau hauv lub magnetic teb, soj ntsuam lub zog ntawm lub rotor, los soj ntsuam cov mechanical rotating system teb. mus rau electromagnetic cuam tshuam, mechanical system muaj qee lub sijhawm ntawm inertia.
tsis siv neeg lub tshuab nqus tsev ntim tshuab lub cev muaj zog rotor txav, feem ntau, yog tag nrho ntau dua lossis tsawg dua nrog cov xwm txheej ntawm oscillation, hauv tib lub mem tes, lub rotor motion attenuation ntawm kev co;
Nyob rau hauv cov nyhuv ntawm nruam mem tes, lub zog yog yuam kev vibration.
Nyob rau hauv tus txheej txheem ntawm kev vibration zaus, amplitude thiab attenuation, thiab txuas nrog lub resonance thiab tawm-ntawm-kauj ruam thiab thiaj li nyob rau, txhua yam nyob ntawm qhov tsis muaj electromagnetic mechanical systems, nrog rau cov duab ntawm electromagnetic torque nkhaus, thiab lwm yam.
1.
Tsis siv neeg lub tshuab nqus tsev ntim tshuab yooj yim qhia cov mis
suav nrog kev sib npaug sib npaug thiab kev sib npaug ntawm lub voj voog
M, rau tag nrho tsis siv neeg lub tshuab nqus tsev ntim tshuab lub cev muaj zog electromagnetic torque, nws cov kev taw qhia zoo los ntawm cov kev taw qhia ntawm lub kaum sab xis nce.
Nws tus nqi yuav tsum sib npaug rau tus nqi ntawm qhov tam sim no thaum tib lub zog zoo li qub, ob qho tib si cuam tshuam rau lub tshuab hluav taws xob tam sim no tuaj yeem pom tau los ntawm ob qho tib si, ib qho khoom siv yog nyob rau hauv winding tam sim no tivthaiv thiab kev ua haujlwm ntawm maladjustment Angle, M21 (
, 0)
, hu ua synchronous torque;
Lwm qhov kev tivthaiv yog kev ua haujlwm ntawm winding tam sim no tivthaiv thiab angular tshaj tawm thiab M2 (
,D,A)
, hu ua asynchronous torque thiab damping torque.
M = M21 + M2
M1 raws li lub load torque, cov kev taw qhia zoo yog nyob rau hauv cov kev taw qhia ntawm lub kaum sab xis txo, nws yog txiav txim los ntawm lub load, qhov xwm ntawm kev sib raug zoo nrog engine ceev hloov yog varied, nyob rau hauv tshwj xeeb tej zaum nws yuav yog ib tug kaum sab xis txoj hauj lwm muaj nuj nqi. ntau hom,
xws li: (
1)
Ntau txhiab ntawm kev sib txhuam torque (
Ma)
, nws tus nqi tsis muaj dab tsi cuam tshuam nrog kev ceev thiab kev taw qhia yog tas li thiab txav mus rau qhov sib txawv, uas yog qhov tsis sib xws rau cov kev taw qhia ntawm lub angular tshaj tawm.
Los ntawm kev coj cov kev coj zoo, thaum lub angular tshaj tawm raws li lub sij hawm kuj yog qhov zoo, angular tshaj tawm yog qhov tsis zoo thaum nws tsis zoo, lub angular tshaj tawm yog xoom yog cov ntsiab lus tsis tu ncua, qhia hauv cov qauv lej tuaj yeem sau tau,
Mu = kos npe ntawm sig muaj nuj nqi raws li cov cim, nws tsim nyog rau lub sij hawm yog sib npaug zos rau 080 t + 1, D8 / D sib npaug - yog tsis zoo
1, D8 / = 0, nws kuj yog sib npaug rau xoom.
taag kev taw qhia ntawm lub load torque (
M2)
, nws qhov loj thiab cov kev taw qhia, tsis muaj dab tsi ua nrog ceev.
Thaum lub tshuab sim ua liaj ua teb yog hom no.
Thaum lub cev muaj zog tig mus rau ib qho kev taw qhia, cov nyhuv braking, thiab mus rau qhov ntxeev siab, cov nyhuv acceleration.
Yog li, nyob rau hauv tus txheej txheem ntawm kev vibration ceev nyob rau hauv cov xwm txheej ntawm alternating, nws lub luag hauj lwm thiab qhuav kev sib txhuam load tsis zoo li qub.
Tab sis tsis txhob hloov nyob rau hauv cov kev taw qhia ntawm rotating ceev, cov nyhuv ntawm ob qho tib si tsis txawv.
tam sim no koj paub cov lus qhia yooj yim thiab cov ntsiab lus tsis zoo ntawm lub tshuab nqus tsev tsis siv neeg lub tshuab nqus tsev, yog tias tuaj yeem paub ntau ntxiv txog
packing tshuab muaj ntau cov lus hauv peb lub vev xaib.
Nws yog qhov tsis ntseeg tias cov txiaj ntsig checkweigher. Kev lag luam kev xav tau muaj zog, tshwj xeeb tshaj yog nyob rau hauv lub teeb ntawm kev loj hlob ntawm lub tshuab hnyav tau pom thoob ntiaj teb.
Smart Weigh Ntim Machinery Co., Ltd muaj ntau qhov sib txawv ntawm suav nrog ntau lub taub hau hnyav, checkweigher thiab lub tshuab hnyav, thiab lwm yam.
Ntse Weigh Ntim Machinery Co., Ltd pom tias hnyav li evolutionary ntau dua li kev hloov pauv. Peb ib txwm muaj cov kev lag luam 'kev lag luam' hauv qee hom.
