No ke aha e hoʻolaha ai ʻo Neodymium magnet i nā kaʻa uila i kaulana ma Kina?Ma waena o nā ala kaʻa a pau, ʻo ka uila uila ka kaʻa kūpono loa no nā kauhale a me nā kūlanakauhale.He maʻalahi, maʻalahi, a me ke kaiapuni.
I nā lā mua, ʻo ka mea hoʻoikaika pololei loa no nā E-bikes e puhi i ke ahi ʻo ia ka palena ʻana i nā kaʻa.I ka manawa like, ʻo ka lawe ʻana a me ka lawe ʻana i nā ʻoihana hoʻolaha e kokoke loa e hoʻopaʻa ʻia, ka mea i hoʻonui i ka koi no nā kaʻa uila.
E like me nā ʻenehana koʻikoʻi e pili ana i nā kaʻa kaʻa uila e like me nā kaʻa uila a me nā pihi e lilo i mea makua a paʻa, ʻoi aku ka maikaʻi o ka holomua ʻenehana a me ka hana nui o nā magnet NdFeB sintered e hāʻawi i nā kaʻa uila i ʻoi aku ka maikaʻi no nā kaʻa uila, e like me ka torque hoʻomaka nui, ikaika piʻi ikaika, kiʻekiʻe ka pono, haʻahaʻa leo, haʻahaʻa hāʻule haʻahaʻa a me ke kumukūʻai waiwai.Ua hoʻohaʻahaʻa hou ʻia ka paepae no ke kūkulu ʻana i nā kaʻa uila, e hiki ai i nā poʻe ke komo i ka mākeke.
ʻO ke kaʻa huila huila ka motika uila menā mākēneki kaʻa huilahoʻokomo ʻia ma ka huila.ʻO kāna hiʻohiʻona nui, ʻo ia ka hoʻohui ʻana o ka mana, ka hoʻouna ʻana a me ka braking i loko o ka huila huila, no laila ua maʻalahi loa ka ʻāpana mechanical o ke kaʻa uila.
I kēia manawa, hoʻohana ka hapa nui o nā kaʻa uila NdFeB i nā kaʻa huila mau loa.Hoʻohauʻoli ʻia ka huila kaʻa e ka magnet mau.Nui nā ʻano kaʻa huila hub uila e hoʻohana i kēiaNeodymium square magnetka nui 24×13.65x3mm me ka papa N35H.Pono kēlā me kēia ʻāpana o nā kaʻa uila he 46 mau ʻāpana huila huila.Hoʻokumu ʻia kekahi o ka rotor a me ka stator magnetic o ka mīkini paʻa paʻa e ka ʻeke uea, a ʻo kekahi e hana ʻia e ka magnet mau loa.No ka mea ʻaʻole hoʻohana ʻia ka coil excitation, mālama ia i ka ikehu uila i hoʻopau ʻia e ka excitation coil i ka wā o ka hana, a hoʻomaikaʻi i ka pono hoʻololi electromechanical o ka kaʻa.Hiki i kēia ke hoʻemi i ke kaʻa kaʻa a hoʻonui i ka mileage no nā kaʻa uila me ka hoʻohana ʻana i ka ikehu ma luna o ka moku.
Aia kekahi mau hoʻololi hou a puni 2016. ʻO ka mea nui kēia ma muli o ka puka ʻana mai o nā kaʻa ʻōpio, ʻoi aku ka kiʻekiʻe a, ʻoiaʻiʻo, ʻoi aku ka nui o nā kaʻa uila i hōʻike ʻia e NIU.ʻO kekahi o nā wahi kūʻai kūʻai o NIU ʻo ia ka hoʻohana ʻana i nā pākahi lithium me ke kaumaha ʻoi aku ka māmā, ʻoi aku ka nui a me ka lōʻihi o ke ola lawelawe, ma kahi o ʻehā a ʻelima mau makahiki.I kēlā manawa, ʻoi aku ka nui o ka 90% o ka mākeke kaʻa uila i hoʻohana i nā pākaukau lead-acid, a ʻo ka helu komo ʻana o nā pā lithium he 8% wale nō.I kēia manawa, ʻo SUNRA, AIMA, YADEA, TAILG, LUYUAN, etc. ʻO NIU a me NINEBOT, ka mea i kapa ʻia nā kaʻa uila kiʻekiʻe akamai, he wahi mākeke liʻiliʻi loa.Ua wānana ʻia kaE-bike magnetE ulu wikiwiki ana ka pono a me ka mākeke o nā kaʻa uila ma nā ʻāina lehulehu e like me Kina, e like me India.
