SIMO: Yuav ua li cas txo qhov poob ntawm YE3 lub cev muaj zog?

Thaum hluav taws xob hluav taws xob hloov mus rau hauv mechanical zog, lublow-voltage motornws tus kheej kuj yuav poob ib feem ntawm lub zog.LT SIMO motorcoj koj kom nkag siab qhov poob ntawm lub cev muaj zog. Qhov poob ntawmYOG 3 motortuaj yeem muab faib ua peb ntu: qhov sib txawv tsis sib xws, kev poob ruaj khov thiab poob poob.

1. Kev poob qis sib txawv nrog cov load, suav nrog stator tsis kam (tooj liab), rotor tsis kam thiab txhuam tsis kam.
2. Kev poob ruaj khov yog ywj siab ntawm cov load, nrog rau cov tub ntxhais poob thiab cov neeg kho tshuab poob. Cov tub ntxhais poob muaj hysteresis poob thiab eddy tam sim no poob, uas yog proportional rau lub square ntawm qhov voltage thiab inversely proportional rau zaus.
3. Lwm qhov kev poob qis yog kev poob qis thiab lwm yam kev poob, nrog rau kev sib txhuam poob ntawm cov bearings thiab windage poob los ntawm kev sib hloov ntawm cov kiv cua thiab rotor.

A. Stator poob

Cov txheej txheem tseem ceeb los txo qhov 1^2R poob ntawm YE3 lub cev muaj zog stator yog raws li hauv qab no:

1. Nyob rau hauv tib lub stator txheej txoj kab uas hla, nce qhov cross-sectional cheeb tsam ntawm lub stator slot yuav txo qhov sib nqus Circuit Court cheeb tsam thiab ua rau kom cov hlau nplaum ntom ntom ntawm cov hniav.
2. Rau qhov tsawg-voltage me YE3 motors, ua kom tag nrho qhov sib piv ntawm stator qhov. Tag nrho qhov ntawm tus stator tuaj yeem nce ntxiv los ntawm kev siv qhov zoo dua winding thiab rwb thaiv tsev loj thiab loj dua tus neeg xyuas pib hla ntu ntu.
3. Qhov kawg poob ntawm stator winding nyiaj rau 1/4 ~ 1/2 ntawm tag nrho cov winding poob. Txo qhov ntev ntawm qhov kawg winding tuaj yeem txhim kho qhov ua tau zoo ntawm YE3 lub cev muaj zog. Cov txiaj ntsig kev sim qhia tau tias qhov kawg qhov ntev yog txo los ntawm 20% thiab qhov poob yog txo los ntawm 10%.

B. Rotor poob

Qhov 1^2R poob ntawm YE3 lub cev muaj zog rotor feem ntau cuam tshuam nrog lub rotor tam sim no thiab rotor tsis kam. Cov txheej txheem txuag hluav taws xob sib raug yog raws li hauv qab no:

1. Lub rotor tam sim no tuaj yeem raug txo los ntawm ob yam: nce qhov voltage thiab nce lub zog ntawm YE3 lub cev muaj zog;
2. Ua kom qhov chaw hla ntu ntawm lub rotor qhov;
3. Rau YE3 lub cev muaj zog, nws ua rau muaj kev nkag siab ntau dua los txo qhov tsis kam ntawm rotor winding (xws li siv cov hlau tuab thiab cov khoom siv tsis zoo) vim tias cov motors me feem ntau yog cam khwb cia txhuas rotors. Yog tias siv cam khwb cia tooj liab rotor, tag nrho cov poob ntawm lub cev muaj zog tuaj yeem raug txo los ntawm 10% -15%. Txawm li cas los xij, kev tsim kub ntawm cov cam khwb cia tooj liab rotor yog siab heev, lub tshuab tseem tsis tau nrov, thiab nws cov nqi yog 15% -20% siab dua li ntawm cov cam khwb cia txhuas rotor.

C. Core poob

Cov hlau poob ntawm lub cev muaj zog tuaj yeem raug txo los ntawm kev ntsuas hauv qab no:

1. Txhawm rau txo qhov sib nqus flux ceev, ua kom qhov ntev ntawm cov tub ntxhais hlau kom txo qhov sib nqus flux ceev.
2. Piv txwv li, lub thickness ntawm silicon steel ntawv yuav txo tau los ntawm kev siv txias-kuav los tiag silicon steel ntawv es tsis txhob kub dov silicon steel ntawv, tab sis cov nyias hlau chips yuav ua rau kom cov hlau chips thiab cov nqi ntawm lub cev muaj zog manufacturing.
3. Siv cov ntawv txias-dov silicon steel nrog zoo conductivity los txo hysteresis poob.
4. Siv cov kev ua haujlwm siab hlau chip rwb thaiv tsev txheej.
5. Kev kho cua sov thiab kev tsim khoom siv tshuab, qhov kev ntxhov siab seem tom qab ua cov hlau nti yuav cuam tshuam rau lub cev tsis muaj zog. Thaum ua cov ntawv silicon steel, cov kev taw qhia txiav thiab xuas nrig ntaus shear kev nyuaj siab muaj kev cuam tshuam zoo rau cov hlau tsis zoo. Txiav raws li cov kev taw qhia dov ntawm silicon steel ntawv thiab tshav kub kho silicon steel ntawv tuaj yeem txo qhov poob los ntawm 10% ~ 20%.

D. Stray poob

Tam sim no, kev nkag siab ntawm kev poob qis ntawm YE3AC lub cev muaj zog tseem nyob rau theem tshawb fawb

1. Kev kho cua sov thiab ua tiav yog siv los txo cov rotor nto luv luv Circuit Court.
2. Sab hauv ntawm lub rotor qhov yog insulated.
3. Txhim kho qhov tsim ntawm stator winding kom txo cov harmonics.
4. Los ntawm kev txhim kho cov qauv tsim thiab kev sib txuam ntawm rotor slots, nce stator thiab rotor slots, tsim rotor slots rau hauv skew slots, thiab siv sinusoidal windings, dispersed windings thiab luv pitch windings nyob rau hauv series, high-order harmonics yuav txo tau zoo heev. Los ntawm kev siv cov hlau nplaum sib nqus los yog sib nqus sib nqus wedges es tsis txhob siv cov kab nrib pleb insulating, thiab sau qhov khoob ntawm stator core ntawm lub cev muaj zog nrog sib nqus sib nqus av nkos, nws yog ib txoj hauv kev zoo los txo qis kev poob ntxiv.

E. Cua kev sib txhuam poob

Cua kev sib txhuam poob nyiaj txog li 25% ntawm tag nrho cov poob ntawm lub cev muaj zog thiab yuav tsum tau them sai sai rau. Kev sib txhuam poob feem ntau yog tshwm sim los ntawm cov kabmob thiab cov ntsaws ruaj ruaj, thiab kev sib txhuam poob tuaj yeem raug txo los ntawm kev ntsuas hauv qab no:

1. Qhov loj ntawm cov ncej yuav tsum tau txo kom ntau li ntau tau, tab sis nws yuav tsum ua kom tau raws li qhov yuav tsum tau ntawm cov zis torque thiab rotor dynamics.
2. Siv cov kabmob ua haujlwm siab.
3. Siv cov tshuab lubrication zoo thiab lubricants.
4. Siv cov tshuab sealing siab heev.
