• Kev piav qhia ntxaws ntawm Mainstream Motor Hom

1. AC Asynchronous Tsav

AC asynchronous motors, tshwj xeeb tshaj yog peb -theem squirrel-cage asynchronous motors, yog cov tsis muaj kev cuam tshuam "lub zog tseem ceeb" hauv kev siv twj, nrog kev lag luam feem ntau tshaj 90%.

Txoj Cai Ua Haujlwm:Thaum peb -theem AC tam sim no raug siv rau stator windings, ib qho kev sib nqus sib nqus yog tsim. Qhov no magnetic teb txiav cov rotor tuav, inducing ib tug tam sim no nyob rau hauv lub rotor, uas nyob rau hauv lem generates electromagnetic torque tsav lub rotor tig. Lub rotor ceev yog ib txwm me ntsis qis dua lub synchronous ceev, nthuav tawm "slip".

Cov yam ntxwv technical:

Qhov zoo:Cov qauv yooj yim, muaj zog thiab ruaj khov, tsis tshua muaj nqi tsim khoom, yooj yim txij nkawm, thiab muaj kev ntseeg siab heev. High℃ntawm standardization (xws li, IEC cov qauv), thiab zoo interchangeability.

Qhov tsis zoo:Kev ua haujlwm qis dua thiab lub zog muaj zog nyob rau hauv lub teeb load; Kev tswj ceev yuav tsum muaj qhov hloov pauv ntau zaus, thiab qhov nrawm nrawm yog txwv.Pumping Applications: Dav siv nyob rau hauv yuav luag txhua yam ntawm cov twj centrifugal thiab cov twj tso kua mis zoo, tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov uas tsis tu ncua, tsis xav tau kev ceev ceev, los yog rhiab heev rau cov nqi pib, xws li kev tsim cov dej thiab cov kua dej, kev lag luam circulating dej, thiab kev ua liaj ua teb irrigation.

Kev txiav txim siab xaiv:Ua kom pom tseeb ntawm chav kawm ua haujlwm (piv txwv li IE1, IE2, IE3, IE4 raws li IEC 60034-30-1 tus qauv). Thaum ua tau raws li kev khiav hauj lwm, ua ntej cov motors nrog cov chav kawm ua haujlwm zoo dua kom txo tau cov nqi khiav haujlwm mus sij hawm ntev.

 

2. Permanent Magnet Synchronous Motors

Cov hlau nplaum ruaj khov synchronous motors (PMSMs) yog cov hnub qub nce siab hauv kev ua haujlwm siab - siv tau zoo nyob rau xyoo tas los no, tshwj xeeb tshaj yog ua tau zoo hauv cov xwm txheej sib txawv ntawm cov tsav tsheb.

Thaum lub stator windings yog sequentially energized, lub generated magnetic teb attracts lub rotor lub salient ncej mus rau txoj hauj lwm ntawm tsawg reluctance, yog li ua rau lub rotor tig tsis tu ncua. Ob qho tib si stator thiab rotor yog cov qauv zoo nkauj; lub rotor tsis muaj cov hlau nplaum ruaj khov lossis windings, uas ua rau cov qauv yooj yim thiab muaj zog.

Cov yam ntxwv technical:

Qhov zoo:Cov qauv yooj yim heev thiab muaj zog; lub rotor tsuas yog ua los ntawm cov ntawv sib dhos silicon steel, uas ua rau tus nqi qis thiab muaj peev xwm tiv taus qhov kub thiab txias heev; siab pib torque; muaj zog ua txhaum cai, tso cai rau txo qis kev ua haujlwm txawm tias muaj ib zaug ntawm - theem tsis ua haujlwm.

Qhov tsis zoo:Qhov tseem ceeb torque ripple thiab suab nrov / vibration; kuj complex tswj system; feem ntau yuav tsum muaj lub ntsuas qhov ntsuas.

Pumping Applications:Feem ntau siv rau hauv kev ua haujlwm hnyav, xws li cov av nkos ntawm cov roj drilling platforms, mine kua thiab slurry twj, lossis micro twj xav tau ultra- siab- ua haujlwm ceev. Cov xwm txheej no ua rau muaj kev xav tau ntau dua ntawm qhov muaj zog thiab kev ntseeg siab ntawm lub cev muaj zog dua li ntawm lub suab nrov thiab smoothness.

 

4. DC Tsav

Txawm hais tias tsis tshua muaj tshwm sim hauv cov ntawv thov, DC motors tseem muaj txiaj ntsig hauv thaj chaw tshwj xeeb.

Txoj Cai Ua Haujlwm:DC tam sim no yog nkag mus rau lub armature windings los ntawm txhuam thiab ib tug commutator, interacting nrog stator magnetic teb los tsim torque.

Cov yam ntxwv technical:

Qhov zoo:Kev tswj ceev ceev zoo heev; kev tswj kev nrawm nrawm dhau ntawm ntau yam tuaj yeem ua tiav yam tsis muaj kev hloov pauv ntau zaus; siab pib torque.

Qhov tsis zoo:Txhuam thiab commutators yog cov khoom siv sib txuas, ua rau muaj kev cuam tshuam thiab hnav, yuav tsum tau saib xyuas tsis tu ncua; kuj tsis tshua muaj kev ntseeg; tsis haum rau qhov chaw tawg thiab tawg.

Pumping Applications:Tam sim no feem ntau yog siv hauv roj teeb- cov twj siv hluav taws xob ntawm cov khoom siv txawb (xws li tsheb engineering thiab nkoj), lossis hauv qee lub tshuab qub uas tsis tau hloov kho hluav taws xob. Hauv kev xaiv txoj haujlwm tshiab, "AC lub cev muaj zog + zaus hloov pauv" kev daws teeb meem tau hloov pauv ntau.
