Qhov zoo ntawm tooj liab hlau lub cev muaj zog piv nrog txhuas hlau lub cev muaj zog

Lub ntsiab zoo ntawm tooj liab hlau motors tshaj txhuas hlau motors yog reflected nyob rau hauv lawv cov conductivity, zog efficiency, tshav kub tsis kam, mechanical zog, thiab kev pab cuam lub neej. Nov yog ib qho kev sib piv tshwj xeeb:

1.Conductivity thiab Energy Efficiency:

 

Lub resistivity ntawm tooj liab (li 1.72 × 10 ⁻⁸Ω· m ntawm 20 degree) tsuas yog 61% ntawm cov txhuas (2.82 × 10 ⁻⁸Ω· m), qhia txog kev ua haujlwm siab dua.

Nyob rau tib lub zog, Joule kub poob ntawm tooj liab hlau motors qis dua, thiab lawv lub zog efficiency feem ntau yog 3% -8% siab dua li ntawm txhuas hlau motors. Piv txwv li, 1.5kW cua txias lub cev muaj zog siv 1.6 kWh ib teev rau tooj liab hlau qauv thiab 1.7-1.8 kWh rau txhuas hlau qauv, nrog rau qhov sib txawv txhua xyoo txog li 29-58 yuan (xws li 0.5 yuan / kWh). cov

2.Heat resistance thiab lifespan

 

Lub melting point ntawm tooj liab (1083 degree) yog ntau dua li ntawm txhuas (660 degree), thiab nws tseem tuaj yeem ua haujlwm ruaj khov hauv qhov kub thiab txias (xws li saum toj 40 degree).

Lub neej tsim ntawm tooj liab hlau motors feem ntau yog 8-15 xyoo, thiab qee qhov kev lag luam qib motors tuaj yeem ncav cuag ntau tshaj 20 xyoo; Lub neej ntawm txhuas hlau motors feem ntau yog 3-8 xyoo.

4.Mechanical zog thiab kev ntseeg tau

Tooj liab muaj lub zog tensile zoo dua (Ntau dua lossis sib npaug ntawm 200MPa) thiab ductility (Ntau dua lossis sib npaug li 30%) dua li txhuas (lub zog tensile 100-150MPa), thiab winding muaj zog tiv taus qaug zog.

Tooj hlau tuaj yeem ncaj qha rau kev sib txuas, nrog kev sib koom ua ke siab; Txhuas cov xov hlau yuav tsum tau muab siab rau tooj liab txhuas hloov terminals, uas tuaj yeem ua xoob yog tias tsis ua tiav.

5. Nyhav thiab ntim:

Qhov ceev ntawm tooj liab hlau motors (8.96g / cm ³) yog 3.3 npaug ntawm txhuas, tab sis vim yog nyias hlau txoj kab uas hla, lub ntim yuav raug txo los ntawm 15% -20% nyob rau hauv tib lub hwj chim, ua rau nws haum rau qhov chaw txwv cov khoom (xws li cua txias nyob rau hauv tsev). cov

Siv tau scenarios:

Qhov tseem ceeb tshaj plaws yuav tsum tau muab rau cov khoom siv tooj liab hlau: ntev- cov khoom siv ua haujlwm tsis tu ncua (xws li cov tshuab ua haujlwm, lub tshuab cua hauv nruab nrab), siab - qhov kub thiab txias (xws li qhov cub), thiab siab- cov khoom siv hauv tsev ua haujlwm tau zoo (xws li thawj theem zog- cov tub yees kom zoo). cov

Aluminium hlau motors tsuas yog tsim nyog rau cov nqi qis, luv- nyob, lossis cov khoom siv nqa tau xws li cov kiv cua me me thiab cov twj tso dej pov tseg.

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

1.Conductivity thiab Zog Efficiency

Lub conductivity ntawm tooj liab (kwv yees 58.5 × 10 ⁶ S / m) yog qhov siab dua li ntawm txhuas (li 37.7 × 10 ⁶ S / m), thiab nws cov resistivity tsuas yog li 60% ntawm cov txhuas. Qhov no tso cai rau tooj liab hlau motors ua kom muaj cua sov tsawg dua ntawm tib lub zog tam sim no, nrog rau kev hloov pauv hluav taws xob feem ntau 3% -8% siab dua aluminium hlau motors. Kev ua haujlwm ntev tuaj yeem txuag tau cov nqi hluav taws xob ntau. Piv txwv li, yog tias lub cev muaj zog 1.5kW khiav tsis tu ncua rau 8 teev hauv ib hnub, tus nqi hluav taws xob txhua xyoo rau cov qauv tooj liab yuav yog 29-58 yuan qis dua li cov qauv txhuas hlau.

2. Nqi thiab kev lag luam

Tus nqi ntawm txhuas yog li 1/3 txog 1/5 ntawm cov tooj liab, yog li tus nqi pib ntawm txhuas hlau motors feem ntau yog 15% -30% qis dua ntawm tooj liab hlau motors. Txawm li cas los xij, los ntawm kev xav ntawm tag nrho cov nqi ntawm lub neej, tooj liab hlau motors tej zaum yuav siv nyiaj ntau dua rau kev siv mus sij hawm ntev vim lawv lub zog ua haujlwm siab thiab kev saib xyuas tsawg. Piv txwv li, nyob rau hauv kev lag luam scenarios qhov twg lub sij hawm ua hauj lwm tshaj 5000 teev, tag nrho cov nqi khiav hauj lwm ntawm tooj liab motors tej zaum yuav 12% -18% qis tshaj ntawm txhuas motors.

3. Nyhav thiab ntim

Qhov ntom ntawm aluminium tsuas yog 30% ntawm tooj liab, ua rau txhuas hlau motors sib zog thiab haum rau cov khoom siv nqa tau xws li drones lossis cov cuab yeej tuav. Tab sis kom them nyiaj rau qhov tsis txaus conductivity, txhuas hlau yuav tsum tau nce cov hlau txoj kab uas hla los ntawm 30% -40%, ua rau lub cev muaj zog uas feem ntau yog 15% -35% loj dua tooj liab hlau motors, uas txwv nws daim ntawv thov nyob rau hauv compact khoom. cov

Hauv cov ntsiab lus, thaum xaiv, nws yog qhov yuav tsum tau ntsuas qhov kev ua tau zoo thiab cov nqi siv nyiaj: nrhiav kev ua haujlwm zoo thiab ua haujlwm ntev los ntawm kev xaiv tooj liab; Ua tib zoo saib rau lub teeb yuag thiab qis - nqi aluminium hlau xaiv. Nrog rau kev txhim kho thev naus laus zis, cov ntaub ntawv sib xyaw xws li tooj liab- clad aluminium yog maj mam txo qhov sib txawv ntawm ob.
