Zog Efficient 3-Phase Induction Tsav

Dab tsi yog peb-theem induction lub cev muaj zog?

Peb-theem induction lub cev muaj zog yog lub cev muaj zog, txhim khu kev qha thiab ruaj khov hluav taws xob siv dav hauv kev lag luam. Lub cev muaj zog no ua kom muaj qhov sib nqus sib nqus los ntawm peb-theem alternating tam sim no, uas ua rau lub rotor tig thiab hloov hluav taws xob rau hauv lub zog siv tshuab. Nws cov yam ntxwv tseem ceeb suav nrog kev pib lub zog siab, kev saib xyuas qis thiab lub neej ntev, haum rau ntau yam kev siv xws li twj, kiv cua, compressors thiab conveyor systems. Peb-theem induction motor muaj cov qauv yooj yim thiab feem ntau muaj cov stator, rotor thiab vaj tse. Nws tuaj yeem ua haujlwm ruaj khov hauv ib puag ncig hnyav thiab txo cov khoom siv tsis ua haujlwm thiab lub sijhawm poob. Nws cov kev ua haujlwm siab kuj ua rau nws zoo heev hauv kev txuag hluav taws xob thiab txo qis emission, thiab nws yog ib qho khoom tseem ceeb thiab tseem ceeb hauv cov khoom siv niaj hnub no.

Kev tsim kho peb-theem Induction Tsav

Peb-theem induction lub cev muaj zog yog dav siv nyob rau hauv cov ntawv thov kev lag luam vim nws cov qauv yooj yim thiab muaj zog. Nws feem ntau muaj ob ntu: stator thiab roto

1. Stator
Lub stator yog qhov ruaj khov ntawm lub cev muaj zog thiab feem ntau suav nrog peb ntu hauv qab no:
Stator ncej: Qhov no yog cov qauv sab nraud ntawm lub cev muaj zog, uas muab kev txhawb nqa thiab kev tiv thaiv rau cov tub ntxhais stator thiab stator winding. Sab nrauv ntawm tus ncej feem ntau yog muab cov dab dej kub los pab kom cov cua sov thiab txias. Nyob ntawm qhov loj thiab lub hom phiaj ntawm lub cev muaj zog, lub stator ncej tuaj yeem ua los ntawm cov ntaub ntawv xws li cam khwb cia hlau, machined steel, aluminium / aluminium alloy lossis stainless hlau.
Stator core: Nws yog tsim los ntawm cov ntawv sib dhos silicon steel thiab siv los ua cov hlau nplaum sib nqus thiab txhim kho lub cev muaj zog.
Stator winding: Nws yog embedded nyob rau hauv lub slots ntawm lub stator core thiab generates ib tug rotating magnetic teb los ntawm peb-theem alternating tam sim no los tsav cov kev sib hloov ntawm lub rotor.
2. Rotor
Lub rotor yog lub rotating ib feem ntawm lub cev muaj zog, uas yog ntsia rau hauv lub stator thiab txhawb nqa los ntawm bearings kom ua tiav kev sib hloov. Cov qauv ntawm lub rotor feem ntau muab faib ua ob hom: tawb rotor thiab lub qhov txhab rotor.
Cage rotor: Nws muaj cov kab hluav taws xob thiab cov nplhaib luv luv ntawm ob qho kawg, uas zoo li lub tawb. Nws cov qauv yog yooj yim thiab haum rau feem ntau cov ntawv thov kev lag luam.
Cov kab mob rotor: Cov winding txuas nrog rau sab nraud Circuit Court los ntawm cov hlua khi thiab txhuam, thiab qhov pib kuj tuaj yeem hloov kho. Nws yog siv nyob rau hauv lub sij hawm uas siab dua pib torque yuav tsum tau.

Lub luag haujlwm ntawm stator ncej
Lub stator ncej tsis tsuas yog muab kev txhawb nqa rau cov tub ntxhais stator thiab stator winding, tab sis kuj muaj cov haujlwm hauv qab no:
Muab cov neeg kho tshuab lub zog los xyuas kom meej qhov ruaj khov thiab kav ntev ntawm lub cev muaj zog.
Lub dab dej kub yog tsim los rau cov cua kub dissipation thiab txias kom tsis txhob muaj lub cev muaj zog los ntawm overheating.
Kev xaiv cov khoom sib txawv (xws li cam khwb cia hlau, aluminium alloy, thiab lwm yam) tuaj yeem hloov mus rau qhov chaw ua haujlwm sib txawv thiab xav tau.

Qhov no yooj yim thiab ruaj khov qauv tsim ua rau peb-theem induction lub cev muaj zog ua tau zoo nyob rau hauv cov ntawv thov kev lag luam. Nws muaj qhov zoo ntawm qhov pib torque siab, tsis tshua muaj kev tu ncua thiab lub neej ntev. Nws yog ib qho indispensable hwj chim qhov chaw nyob rau hauv ntau yam mechanical khoom.
 

Hom Peb-theem Induction Motors
Peb-theem motors feem ntau muab faib ua ob hom raws li lub rotor winding (armature coil winding), uas yog,squirrel tawbthiabswb nplhaib hom (qhov txhab rotor motors).
1.Lub cev muaj zog induction lub cev muaj zog, muaj npe rau nws cov duab rotor uas zoo ib yam li lub tawb squirrel, yog ib hom kev siv ntau yam ntawm induction motor.
Lub rotor qauv ntawm lub cev muaj zog yog yooj yim thiab muaj zog, thiab yuav luag 80% ntawm induction motors yog hom no. Lub rotor muaj ib tug cylindrical laminated core nrog inclined slots nyob rau sab nraud ncig ntawm cov tub ntxhais. Qhov kev tsim no tuaj yeem tiv thaiv kev sib nqus sib nqus ntawm cov stator thiab cov hniav rotor, ua kom lub cev muaj zog thiab txo cov suab nrov. Tsis tas li ntawd, qhov tsim no nce qhov ntev ntawm tus neeg xyuas pib rotor, yog li ua kom cov rotor tsis kam.
Tsis zoo li cov rotor windings ib txwm muaj, squirrel tawb rotor muaj cov rotor tuav ua los ntawm txhuas, tooj dag lossis tooj liab. Ob qhov kawg ntawm rotor tuav yog luv luv-circuited los ntawm qhov kawg rings los tsim ib lub voj kaw tiav thiab muab cov khoom tsim nyog rau kev txhawb nqa. Txij li thaum lub rotor tuav yog luv luv, nws yog tsis yooj yim sua kom ntxiv lwm yam kuj rau lub rotor Circuit Court.
Txij li cov hlua khi thiab txhuam tsis siv, squirrel tawb induction motor muaj cov qauv yooj yim thiab muaj zog dua, uas ua rau nws siv dav hauv kev lag luam.

2.Slip-ring induction motors, tseem hu ua mob rotor motors, muaj ib tug tshwj xeeb rotor tsim. Lub rotor muaj ib tug cylindrical laminated tub ntxhais nrog cov qhov nyob ib ncig ntawm lub periphery ntawm cov tub ntxhais, nyob rau hauv uas lub rotor windings tau muab tso rau.
Nyob rau hauv hom rotor no, tus naj npawb ntawm cov ncej ntawm cov windings sib tw nrog tus naj npawb ntawm cov ncej ntawm stator windings thiab tuaj yeem txuas rau hauv lub hnub qub lossis delta configuration. Qhov kawg ntawm lub rotor windings yog txuas nrog rau sab nraud Circuit Court los ntawm cov hlua khi, uas yog qhov uas lub nplhaib nplhaib induction lub cev tau txais nws lub npe.
Qhov kev tsim no tso cai rau sab nraud tsis kam txuas nrog lub rotor Circuit Court ntawm lub nplhaib thiab txhuam, tso cai rau kev tswj xyuas meej ntawm lub cev muaj zog thiab nce lub zog pib rau peb-theem induction motors. Qhov kev hloov pauv no ua rau lub nplhaib-ntiv nplhaib induction motors tshwj xeeb tshaj yog muaj txiaj ntsig zoo hauv cov ntawv thov uas yuav tsum tau hloov kho ntawm kev pib ua haujlwm thiab cov yam ntxwv ua haujlwm.

Daim duab hluav taws xob ntawm lub nplhaib-ntiv nplhaib peb-theem induction lub cev muaj zog nrog sab nraud resistor.

Ua hauj lwm hauv paus ntsiab lus ntawm peb-theem induction lub cev muaj zog

Thaum peb-theem fais fab txuas nrog stator winding, lub stator winding yuav tsim kom muaj qhov sib nqus sib nqus (RMF), qhov ceev uas yog hu ua synchronous speed (Ns). Lub stator windings feem ntau sib tshooj ntawm 120 degree (lub kaum sab xis hluav taws xob) kom ntseeg tau tias muaj cov khoom sib nqus sib nqus.
Raws li Faraday txoj cai lij choj ntawm electromagnetic induction, vim qhov kev hloov pauv ntawm lub rotating magnetic teb (dΦ / dt), electromotive quab yuam yog induced nyob rau hauv lub rotor Circuit Court. Qhov no electromotive quab yuam generates tam sim no nyob rau hauv lub rotor winding. Txij li thaum lub rotor Circuit Court yog ib txoj kev kaw, qhov induced electromotive quab yuam ua rau tam sim no ntws nyob rau hauv lub rotor Circuit Court.
Txij li thaum tus neeg xyuas pib nqa tam sim no tsim ib qho chaw sib nqus, qhov tam sim no nyob rau hauv lub rotor generates ib tug tshiab magnetic teb. Muaj ib qho kev txheeb ze ntawm stator magnetic teb thiab rotor magnetic teb, yog li lub rotor pib tig los txo qhov kev txheeb ze ntawm cov lus tsa suab. Nyob rau hauv lwm yam lus, lub rotor sim "catch" lub rotating magnetic teb ntawm stator thiab yog li pib tig.
Cov kev taw qhia ntawm kev sib hloov yog txiav txim los ntawm Lenz txoj cai, thiab cov kev taw qhia ntawm lub cev muaj zog lub rotor yog raws li cov kev taw qhia ntawm lub rotating magnetic teb generated los ntawm lub stator. Txij li thaum tam sim no nyob rau hauv lub rotor yog generated los ntawm induction, lub cev muaj zog no hu ua induction motor.
Txawm li cas los xij, qhov tseeb ceev ntawm lub rotor yog ib txwm me ntsis qis dua li synchronous ceev. Txawm hais tias lub rotor sim ua kom raws li stator lub rotating magnetic teb, nws tsis tuaj yeem "catch" nws tag nrho, yog li nws qhov ceev yog ib txwm qis dua li synchronous ceev. Lub synchronous ceev nyob ntawm lub hwj chim mov zaus thiab tus naj npawb ntawm cov ncej ntawm lub cev muaj zog. Qhov sib txawv ntawm qhov ceev thiab synchronous ceev yog hu ua plam.
