Nyob rau hauv ib txwm siv hlau nplaum motors, vim yog qhov tsis tuaj yeem muaj kev sib haum xeeb hauv huab cua sib nqus sib nqus, feem ntau yog tsim nyog los txais yuav cov ramps ntawm stator thiab rotor cov qauv kom tsis muaj zog. Lub precision Halbach array air-gap magnetic teb ntawm Hangzhou Magnet zog Technology muaj ib tug high degree ntawm sinusoidal magnetic teb tis thiab me me harmonic cov ntsiab lus. Qhov no tshem tawm qhov xav tau ntawm skews hauv stator thiab rotor, uas tsis tsuas yog ua kom yooj yim rau lub cev muaj zog, txo cov khoom tsim thiab cov nqi, tab sis kuj txhim kho kev ua haujlwm ruaj khov thiab kev ntseeg siab ntawm lub cev muaj zog.
3.3. Lub rotor tuaj yeem ua los ntawm cov khoom tsis yog cov tub ntxhais
Cov nyhuv tiv thaiv tus kheej ntawm qhov tseeb Halbach array tsim ib qho chaw sib nqus ib sab, uas muab qhov chaw ntau dua rau kev xaiv cov khoom siv rotor. Hangzhou Magnet Technology ua rau kev siv tag nrho ntawm qhov kom zoo dua thiab tuaj yeem xaiv cov ntaub ntawv tsis yog cov khoom siv rotor, uas txo lub sijhawm ntawm inertia thiab txhim kho lub cev muaj zog cov lus teb sai. Qhov no yog qhov tseem ceeb tshwj xeeb tshaj yog rau cov xwm txheej uas yuav tsum tau pib thiab nres thiab hloov ceev ceev, xws li cov kab ntau lawm, neeg hlau thiab lwm qhov chaw.
3.4. Kev siv siab ntawm cov hlau nplaum ruaj khov
Lub precision Halbach array ntawm Hangzhou Magnet zog Technology siv cov kev taw qhia magnetization kom ua tiav qhov kev ua haujlwm siab dua, feem ntau tshaj 0.9, uas zoo heev txhim kho kev siv cov hlau nplaum ruaj khov. Qhov no txhais tau hais tias nrog tib tus nqi ntawm cov hlau nplaum, ib qho chaw sib nqus muaj zog tuaj yeem tsim tau thiab cov khoom tso tawm ntawm lub cev muaj zog tuaj yeem txhim kho. Nyob rau tib lub sijhawm, nws kuj txo qis kev vam khom ntawm cov peev txheej tsawg, txo cov nqi, thiab ua tau raws li cov kev xav tau ntawm kev tsim kho kom ruaj khov.
3.5. Concentrated winding tuaj yeem siv tau
Vim lub siab sinusoidal faib ntawm lub magnetic teb ntawm precision Halbeck array thiab lub me me ntawm lub harmonic magnetic teb, Hangzhou Magnet zog Technology siv tau concentrated windings. Concentrated windings muaj kev ua tau zoo dua thiab poob qis dua li cov khoom siv hluav taws xob uas siv hauv cov hlau nplaum tas li. Tsis tas li ntawd, nkag siab cov winding kuj tseem tuaj yeem txo qhov loj me thiab qhov hnyav ntawm lub cev muaj zog, nce ntxiv cov peev txheej ceev, thiab muab ntau ntxiv rau kev siv lub cev muaj zog.
