Thaum peb-theem stator windings ntawm lub tshuab hlau nplaum ruaj khov (txhua qhov sib txawv ntawm 120 ° hauv lub kaum sab xis hluav taws xob) raug pub nrog peb-theem alternating tam sim no nrog ntau zaus ntawm f, lub rotating magnetic teb uas txav ntawm synchronous ceev yuav. raug tsim tawm.
Nyob rau hauv tsis tu ncua, lub ntsiab ncej sib nqus teb rotates synchronously nrog lub rotating magnetic teb, yog li ntawd lub rotor ceev kuj yog synchronous ceev, lub stator rotating magnetic teb thiab lub ntsiab ncej sib nqus teb tsim los ntawm cov hlau nplaum mus tas li nyob twj ywm zoo li qub, thiab lawv. Kev sib cuam tshuam thiab tsim hluav taws xob torque, Lub cev muaj zog rotates thiab ua lub zog hloov dua siab tshiab.
Cov hlau nplaum tas mus li hloov pauv zaus huab cua compressor txais kev ua haujlwm siab ruaj khov hlau nplaum lub cev muaj zog + inverter (PM lub cev muaj zog).Cov ntsia hlau host thiab high-efficiency hlau nplaum ruaj khovlub cev muaj zog sib koom tib lub ntsiab ncej.Lub cev muaj zog tsis muaj kabmob., kev sib kis efficiency yog 100%.Cov qauv no tshem tawm cov tsoos lub cev muaj zog bearing tsis ua hauj lwm taw tes thiab paub txog lub cev muaj zog txij nkawm-dawb.
Cov khoom siv hlau nplaum tsis tshua muaj hauv ntiaj teb muaj cov khoom sib nqus zoo heev.Tom qab magnetization, nws muaj peev xwm tsim ib tug ruaj khov magnetic teb yam tsis muaj zog sab nraud, uas yog siv los hloov lub zog excitation teb ntawm tsoos motors.., Txhim khu kev lag luam, me me thiab lub teeb yuag.Nws tuaj yeem ua tsis tau tsuas yog ua tau zoo (xws li kev ua haujlwm siab, ultra-siab ceev, ultra-siab teb ceev) unmatched los ntawm cov tsoos hluav taws xob excitation motors, tab sis kuj tuaj yeem ua rau cov motors tshwj xeeb uas tuaj yeem ua tau raws li kev ua haujlwm tshwj xeeb., xws li of elevator traction motors, automotive motors, thiab lwm yam.
Kev sib xyaw ua ke ntawm lub ntiaj teb tsis tshua muaj kev ua haujlwm ruaj khov hlau nplaum lub cev muaj zog nrog lub zog hluav taws xob thiab microcomputer tswj thev naus laus zis tau txhim kho kev ua haujlwm ntawm lub cev muaj zog thiab kev sib kis mus rau qib tshiab:
Lub tshuab hluav taws xob muaj peev xwm ua tau zoo ib txwm muaj peev xwm sib txawv ntawm lub cev muaj zog ib txwm tswj kev ua haujlwm siab nyob rau hauv ib qho kev thauj khoom, txuag ntau dua 38% lub zog piv nrog cov motors zoo tib yam thiab ntau dua 10% lub zog txuag tshaj induction kuj sib txawv zaus motors.
Qhov kev ua tau zoo tshaj ntawm lub cev muaj zog tuaj yeem pib tam sim tom qab lub cev muaj zog nres.Nws tuaj yeem pib thiab nres infinitely tsis cuam tshuam rau lub neej ntawm lub cev muaj zog.Qhov pib tam sim no tsis tshaj 100% ntawm tag nrho cov load tam sim no.
Vim hais tias cov hlau nplaum ruaj khov hloov pauv zaus lub cev muaj zog muaj qhov zoo ntawm qhov tsis tshua muaj kev ceev thiab siab tso zis torque, nws qhov sib txawv zaus tswj hom yog dav dua li qhov sib txawv ntawm lub cev muaj zog induction.Cov hlau nplaum tas mus li hloov pauv zaus lub cev muaj zog yog 30% me dua hauv ntim thiab 35% sib dua hauv qhov hnyav dua cov motors uas muaj zog tib yam, thiab yooj yim rau kev tswj.Yog li ntawd, kev txhim kho cov kev ua tau zoo thiab qib ntawm cov cuab yeej txhawb nqa yog ib qho tseem ceeb ntawm kev txhim kho kev lag luam hauv lub cev los kho cov qauv kev lag luam.
Tam sim no, high-efficiency mus tas li hlau nplaum sib txawv zaus lub cev muaj zog yog qhov kev xaiv zoo tshaj plaws rau cov ntsia hlau cua compressor tsav lub cev muaj zog.Nws muaj txiaj ntsig zoo thiab txuag hluav taws xob ntau dua li peb-theem asynchronous sib txawv zaus lub cev muaj zog!
