Dab tsi yog qhov txawv ntawm tooj liab hlau motors thiab ntshiab tooj liab motors

 

Cov khoom sib txawv muaj qhov sib txawv durability thiab kev pab lub neej.

1. Ntshiab tooj liab muaj cov conductivity zoo dua, thermal conductivity, thiab tsis muaj zog. Lub cev muaj zog ua los ntawm cov tooj liab ntshiab tuaj yeem xa hluav taws xob zoo dua, txhim kho lub cev muaj zog tso zis, thiab txhim kho lub cev muaj zog. Ntshiab tooj liab muaj lub zog tso zis ntau dua li tooj liab hlau.

2. Lub cev muaj zog tooj liab ua los ntawm cov khoom siv tooj liab ntshiab yog qhov ruaj khov dua li lub cev muaj zog ua los ntawm cov khoom siv tooj liab.

3. ntshiab tooj liab motors muaj ib tug kuj ntev kev pab cuam lub neej tshaj tooj liab hlau motors. Vim qhov zoo dua conductivity thiab thermal conductivity ntawm tooj liab ntshiab, lub tshav kub thiab kev tiv thaiv poob generated thaum lub sij hawm coil ua hauj lwm yog heev txo, slowing down tus nqi ntawm lub cev muaj zog lub neej.

 

 

Hauv kev lag luam ntawm lub cev muaj zog, kev xaiv cov khoom siv yog qhov tseem ceeb ntawm kev txiav txim siab cov cuab yeej ua haujlwm thiab tus nqi. tooj liab thiab txhuas, raws li ob qho khoom siv hluav taws xob tseem ceeb, muaj qhov sib txawv ntawm lub cev uas ncaj qha rau cov yam ntxwv ntawm kev ua haujlwm thiab daim ntawv thov ciam teb ntawm cov motors. Kab lus no yuav ua tib zoo txheeb xyuas qhov sib txawv ntawm cov tooj liab aluminium motors los ntawm peb qhov loj: cov ntaub ntawv science, engineering xyaum, thiab kev ua lag luam daim ntawv thov, thiab tshawb nrhiav lawv qhov kev txiav txim siab- ua qhov laj thawj hauv kev xaiv cov tswv yim.

 

 

Qhov txawv ntawm tooj liab hlau lub cev muaj zog thiab txhuas hlau lub cev muaj zog

1. Cov yam ntxwv ntawm cov khoom: Kev ua si ntawm kev coj ua thiab cov khoom siv tshuab

Qhov sib txawv ntawm lub cev muaj zog ntawm tooj liab thiab txhuas tau tso lub hauv paus rau ob txoj kev siv tshuab hluav taws xob. Lub conductivity ntawm tooj liab yog siab li 58.5 × 10 ⁶ S / m, thib ob tsuas yog nyiaj, thaum lub conductivity ntawm txhuas tsuas yog 37.7 × 10 ⁶ S / m, sib npaug rau 64% ntawm tooj liab. Qhov sib txawv no yuav hloov pauv mus rau qhov sib txawv ntawm lub zog poob thaum lub sijhawm ua haujlwm ntawm lub cev muaj zog. Ua ib qho piv txwv ntawm 1kW lub cev muaj zog, nyob rau hauv tib lub load, aluminium motors muaj kev tiv thaiv siab dua thiab kab poob zog txog li 1.5 npaug ntawm cov tooj liab motors. Qhov sib txawv ntawm kev siv hluav taws xob sib txawv hauv lub sijhawm ntev - lub sijhawm ua haujlwm tsis tuaj yeem tsis quav ntsej.

Los ntawm kev xav txog kev ua haujlwm zoo, qhov ductility ntawm tooj liab (elongation ntawm kev tawg ntawm li 45%) nyob deb tshaj li ntawm txhuas (elongation ntawm kev tawg li ntawm 15%), ua rau tooj liab windings yooj yim rau cov duab thaum lub sij hawm sib dhos thiab muaj peev xwm tiv taus kev co thiab thermal expansion thiab contraction thaum lub sij hawm lub cev muaj zog. Lub nkig ntawm txhuas ua rau nws yooj yim rau microcracks thaum lub sij hawm winding txheej txheem, tshwj xeeb tshaj yog nyob rau hauv complex winding lug uas yuav tsum tau rov khoov, uas ho ua rau kom muaj kev pheej hmoo ntawm txhuas hlau puas. Tsis tas li ntawd, cov yeeb yaj kiab oxide ntom ntom (Al ₂ O3) tau yooj yim tsim rau saum npoo ntawm txhuas. Txawm hais tias txheej txheej oxide no muaj kev tiv thaiv zoo, nws tuaj yeem ua rau muaj kev tiv thaiv kev tiv thaiv ntawm cov chaw sib tiv tauj (xws li kev sib txuas ntawm lub davhlau ya nyob twg), ua rau muaj teeb meem hauv zos overheating.

 

2. Kev ua tau zoo: Cov tshuaj tiv thaiv kab mob ntawm kev ua haujlwm, kev kub ntxhov, thiab kev ua neej nyob

Qhov sib txawv ntawm cov khoom siv tuaj yeem ua rau muaj kev cuam tshuam ntawm kev ua haujlwm ntawm lub cev muaj zog. Nyob rau hauv cov nqe lus ntawm conductivity efficiency, tooj liab motors muaj peev xwm ua tau sib npaug tam sim no nqa peev xwm los ntawm finer hlau diameters. Piv txwv li, thaum nqa 10A tam sim no, tooj liab tsuas yog yuav tsum muaj tus ntoo khaub lig- ntu ntu ntawm 1.5mm ², thaum txhuas hlau xav tau 2.3mm ². Qhov sib txawv ntawm txoj kab uas hla tsis tsuas yog cuam tshuam rau qhov chaw ua hauj lwm ntawm lub winding, tab sis kuj ncaj qha cuam tshuam rau lub zog ceev ntawm lub cev muaj zog - nyob rau hauv tib lub ntim, tooj liab motors yuav tsum tau teem nrog ntau lem los yog thicker silicon steel los xij, yog li txhim kho torque tso zis muaj peev xwm.

Qhov sib txawv ntawm kev ua kom sov dissipation yog qhov tseem ceeb tshwj xeeb. Aluminium motors muaj kev ua haujlwm siab dua, ua rau 30% -40% nce hauv Joule cua sov ntawm tib lub zog, yuam cov neeg tsim qauv siv cov kev daws teeb meem zoo dua. Ib qho xwm txheej yog lub cev muaj zog ntawm lub zog tshiab: qis- qauv kawg nrog aluminium windings xav tau lub ntim loj dua ua kua txias, thaum siab -kawg qauv nrog tooj liab windings tuaj yeem tso siab rau huab cua txias kom tau raws li lawv cov kev xav tau cua sov. Qhov kev sib txawv ntawm qhov tsim no yog ncaj qha cuam tshuam rau tag nrho qhov hnyav thiab lub zog noj ntawm lub tsheb - txawm hais tias lub cev muaj zog aluminium txo qhov hnyav ntawm winding, qhov hnyav nce ntawm cov cua kub dissipation system feem ntau offsets cov txiaj ntsig ntawm cov khoom siv lightweighting.

Qhov sib txawv ntawm lub zog txhua yam yog pom tseeb nyob rau hauv ntev - kev cia siab rau lub sij hawm. Raws li cov ntaub ntawv ntsuas tiag tiag los ntawm qee cov khoom siv hauv tsev, hauv kev ntsuas kev laus nrawm simulating 10-xyoo kev pabcuam, qhov tawg ntawm tooj liab lub cev muaj zog yog tsawg dua 0.5%, thaum lub cev muaj zog aluminium nce mus txog 12%. Tshwj xeeb tshaj yog nyob rau hauv daim ntawv thov scenarios uas yuav tsum tau nquag pib nres (xws li lub tshuab ntxhua khaub ncaws), qhov teeb meem qaug zog ntawm aluminium windings yog qhov tseem ceeb dua. Tsis tas li ntawd, qhov teeb meem vuam ntawm txhuas thiab tooj liab tsis tau daws qhov teeb meem. Txawm hais tias ultrasonic vuam tuaj yeem txhim kho qhov kev sib txuas ntawm lub zog, cov txheej txheem nyuaj thiab tus nqi tau nce ntau.
