Alakaʻi: No ke aha e pono ai e hoʻohui i nā wili uila uila i nā spacers magnetic, e hōʻuluʻulu i nā ʻano ʻekolu aʻe:

1. Mākēneki permeability

E like me kā mākou e ʻike ai, ʻo ke kumu o ka QI wireless charging standard no nā pale magnetic he electromagnetic induction. Ke hana nei ka coil mua (wireless charging transmitter), e hoʻoulu i kahi māla magnetic interactive (e loli mau ana ke kuhikuhi o ka ikaika). I mea e hana ai i ka ikehu hoʻokuʻu ʻia e ka coil mua e hana i ka coil lua (wireless charging receiver) e like me ka hiki, pono e alakaʻi ʻia ka magnetism o ka coil.

2. Palaka mākēneki

ʻAʻole hiki i ka pepa magnetic ke hana pono i ka magnetism, akā ke pāʻani pū kekahi i ka pale ʻana i ka magnetism. No ke aha e pale ai i ka magnetism? Ua ʻike mākou i ka wā e hālāwai ai kahi mea hoʻololi magnetic me kahi mea hoʻokele e like me ke metala, inā he uea paʻa ka metala, e hoʻopuka ʻo ia i ke au, inā he uea paʻa ka metala, ʻoi aku hoʻi me kahi ʻāpana metala holoʻokoʻa, e loaʻa kahi hopena eddy current. .

3. Hoʻopau wela

Ke hana nei ke kahua magnetic ma ka coil inductor e hoʻohua i kēia manawa kiʻekiʻe. I loko o kēia kaʻina hana, ʻo ka coil ponoʻī e hoʻoulu i ka wela. Inā ʻaʻole i hoʻopau maikaʻi ʻia kēia wela, e hōʻiliʻili ia. I kekahi manawa, wela loa mākou i ka wā o ka hoʻouka uila. ʻO ka maʻamau, ma muli o ka hoʻomehana ʻana o ka inductance coil a i ʻole ka wela o ka papa kaapuni.
