Sep 30, 2025
Tso lus
Permalloy toroidal cores yog cov cores sib nqus ua los ntawm winding nyias npib tsib xee- hlau alloy sawb rau hauv ib qho kev kaw toroidal. Lub kaw sib nqus hluav taws xob txo cov hlau nplaum sib nqus, txhim kho kev sib nqus, thiab muab tus kheej zoo - tiv thaiv cov hlau nplaum sab nraud. Vim lawv cov ultra-siab permeability thiab qis coercivity, cov cores no tau dav siv nyob rau hauv precision tam sim no transformers thiab rhiab ntsuas cov cuab yeej.
Product Description
Cov qauv toroidal yog qhov txhab los ntawm permalloy sawb kom cov hlau nplaum sib nqus hauv lub nplhaib tsis muaj qhov sib txawv ntawm huab cua. Qhov kev tsim no muab lub siab inductance ib tig, tsis tshua muaj hlau nplaum to, thiab kev ua haujlwm ruaj khov nyob rau hauv me me excitation tam sim no. Cov tub ntxhais tuaj yeem muab tau raws li lub nplhaib liab qab, lossis nrog cov txheej txheem rwb thaiv tsev, daim kab xev, lossis cov ntaub ntawv yas nyob ntawm daim ntawv thov.
Qib khoom
Permalloy yog npib tsib xee- hlau alloy, qee zaum nrog molybdenum ntxiv, thiab tseem hu ua npib tsib xee- hlau alloy lossis mumetal- hom alloy. Cov qib sib xws rau toroidal cores yog 1J77, 1J79, thiab 1J85, uas txawv ntawm cov ntsiab lus nickel thiab kev ua haujlwm sib nqus. Cov qib no muaj qhov pib permeability siab heev, uas ua rau lawv tsim nyog rau kev ntsuas me me tam sim no nrog siab rhiab heev.

Cov yam ntxwv hluav taws xob
Ntawm 50 Hz nrog rau kev sim teb ntawm 1 mOe, thawj permeability ntawm 1J79 yog hais txog 25,000 thiab qhov siab tshaj plaws permeability mus txog 150,000. Rau 1J85, qhov pib permeability yog txog 40,000 thiab qhov siab tshaj plaws permeability mus txog 200,000. Cov txiaj ntsig siab no tso cai rau cov cores me kom xa cov zis hluav taws xob xav tau los ntawm kev ntsuas hluav taws xob.
