High Speed AC Tsav
AC lub cev muaj zogyog ib qho cuab yeej uas hloov cov hluav taws xob hluav taws xob ntawm kev hloov tam sim no rau hauv lub zog siv tshuab.Lub AC lub cev muaj zog feem ntau yog siv los ntawm electromagnet winding los yog faib stator winding siv los tsim ib qho chaw sib nqus thiab tig armature lossis rotor.Lub cev muaj zog yog tsim los ntawm kev siv lub phenomenon ntawm rotating ib tug energized kauj nyob rau hauv ib tug sib nqus teb los ntawm lub zog.Muaj ob hom AC motors: synchronous AC motors thiab induction motors.
Lub stator winding ntawm peb-theem AC lub cev muaj zog yog peb lub kauj sib cais los ntawm 120 degrees los ntawm ib leeg, uas txuas nrog hauv daim duab peb sab lossis lub hnub qub.Thaum peb-theem tam sim no raug siv, ib qho chaw sib nqus yog tsim nyob rau hauv txhua lub kauj, thiab peb qhov chaw sib nqus sib xyaw ua ke kom tau txais qhov sib nqus sib nqus.
AC lub cev muaj zogmuaj stator thiab rotor, thiab muaj ob hom AC motors: synchronous AC motor thiab induction motor.Ob hom motors tsim rotating magnetic teb los ntawm AC tam sim no mus rau hauv stator winding, tab sis lub rotor winding ntawm synchronous AC lub cev muaj zog feem ntau yuav tsum tau muab nrog DC tam sim no (excitation tam sim no) los ntawm exciter, thaum lub rotor winding ntawm induction lub cev muaj zog tsis. yuav tsum tau noj nrog tam sim no.
Lub stator winding ntawm peb-theem AC lub cev muaj zog yog peb lub kauj sib cais los ntawm 120 degrees los ntawm ib leeg thiab txuas rau hauv daim duab peb sab lossis lub hnub qub.Thaum siv peb-theem tam sim no, ib qho chaw sib nqus yog tsim nyob rau hauv txhua lub kauj, thiab peb daim teb tau muab tso ua ke kom tau txais ib qho kev sib hloov.Thaum qhov tam sim no ua tiav ib qho kev vibration tag nrho, lub rotating magnetic teb rotates raws nraim ib lub lim tiam, yog li ntawd, lub revolutions ib feeb ntawm rotating magnetic teb N = 60f.Qhov sib npaug f yog qhov zaus ntawm lub hwj huam mov.
AC motors tuaj yeem muab faib ua cov motors synchronous thiab asynchronous motors (lossis tsis-synchronous motors) raws li tus nqi ntawm rotor rotor.Lub rotor ceev ntawm lub synchronous lub cev muaj zog yog tas li tib yam li qhov ceev ntawm lub rotating magnetic teb tsis hais txog ntawm lub load, yog li no ceev yog hu ua synchronous ceev, thiab raws li tau hais los saum no, tsuas yog txiav txim los ntawm lub zaus ntawm lub hwj chim mov.Qhov ceev ntawm asynchronous lub cev muaj zog tsis tas li, tab sis nyob ntawm qhov loj ntawm lub load thiab qhov voltage ntawm lub hwj chim mov.Ntawm peb-theem asynchronous motors, muaj cov tsis-rectifier motors thiab rectifier motors.Feem ntau ntawm cov asynchronous motors nyob rau hauv kev xyaum yog induction motors tsis muaj rectifier (tab sis lub parallel thiab series peb-theem asynchronous rectifier motors muaj qhov zoo ntawm adjustable ceev nyob rau hauv ib tug ntau yam thiab siab zog factor), thiab nws ceev yog tas li tsawg tshaj li lub synchronous ceev. .
Cov ntawv thov tseem ceeb
AC lub cev muaj zogmuaj kev ua haujlwm siab dua, thiab tsis muaj pa taws, plua plav thiab tsw ntxhiab, tsis muaj kuab paug rau ib puag ncig, thiab suab nrov tsawg.Vim nws cov txiaj ntsig zoo, nws tau siv dav hauv ntau yam xws li kev lag luam thiab kev ua liaj ua teb, kev thauj mus los, kev tiv thaiv hauv tebchaws, kev lag luam thiab khoom siv hauv tsev, khoom siv kho mob, thiab lwm yam.
