ʻO ka motika hea ʻoi aku ka maikaʻi no ka e-uila?

ʻO ka uila uila hea ʻoi aku ka maikaʻi? gears motor? mid drive motor? kaʻa mua?

Hoʻohui ka moto e-uila i ke kino a ʻaʻole hiki ke hoʻololi maʻalahi ʻia e like me nā mea ʻē aʻe, no laila eia nā mea āpau āu e ʻike ai ma mua o kou kūʻai ʻana i kāu uila uila aʻe.
E kaulike nā motika uila e-uila maikaʻi loa ma ka unahi ma waena o ka mana a me ke kaupaona, e hāʻawi i ke kōkua hehi wāwae kiʻekiʻe me ke kaupaona ʻole ʻana i ke kaʻa i lalo a paʻa iā ia. ʻOiaʻiʻo, hele mai nā mīkini uila e-keke ma ke ʻano he ʻāpana o ka paikikala ponoʻī ʻaʻole ia he ʻāpana e hiki ai iā ʻoe ke kuapo a hoʻomaikaʻi. ʻO nā keke uila uila waena maikaʻi loa no laila he mea nui e ʻike i kāu mea e komo nei i ke koho ʻana mai nā keke uila maikaʻi loa.

Ua maikaʻi a paʻa maoli ka e-bike iā ia iho ma ke ʻano he ʻāpana waiwai o ka paikikala ma hope. Ma kahi o ka mākeke e hoʻomalu ʻia e nā uila uila no ka holo ʻana, waiwai nui ia me nā keke kaʻa uila a ʻoi loa hoʻi.

No nā keu pono āpau o nā keke uila, hiki iā lākou ke hana i ka huikau a me ka hopohopo nona, i hoʻoulu ʻia e ka ʻenehana pali kūlia e hoʻoikaika nei i kēia mau paikikala. E like me nā mea uila āpau, ʻo ka noʻonoʻo ke kūʻai lohi ʻana ʻoi aku ka maikaʻi, e ʻae iā ʻoe e pōmaikaʻi i ke kiʻi ʻana i nā ʻenehana hou.

Akā inā ʻaʻohe ou manaʻo kahi e hoʻomaka ai, a laila mākou ma aneʻi e kōkua e hoʻopau i kekahi o nā huikau e pili ana i nā kaʻa uila e-uila maikaʻi loa, a me nā mea hiki iā lākou.

Hiki ke hoʻolako ʻia i kahi keke hopu uila me kekahi o nā ʻano ʻekolu o ka motera, e hāʻawi ana kēlā me kēia i nā ʻano hana like ʻole ma nā ʻāina like ʻole. ʻO ka motika hub hope (waiho ʻia i ka huila o hope) e hoʻohua i ka mana nui a he koho kūpono ia no ka mea e pono ai ka liʻiliʻi o ka mālama ʻana a me ke kumu kūʻai maʻamau. Eia nō naʻe, nāwahiwaliwali kona haʻahaʻa haʻahaʻa i ka piʻi ʻana i kahi ala. 

ʻO ka motika kalaiwa waena (aia ma waena o nā paikikala o nā paikikala) i ʻoi aku ka ikaika o ka ikehu i ka hoʻohālikelike ʻia me ka motika hub hope. No laila, hiki ke piʻi ʻoi aku ka maikaʻi a maʻalahi hoʻi. Ma ka ʻaoʻao lalo, hiki i nā kaʻa me kēia ʻano motera ke ʻoi aku ka uku a koi aku i ka mālama hou ʻana. 

ʻO ka mea hope loa, hāʻawi ka ʻenekini kalaka ʻoi loa i ka kaohi maikaʻi a me ka hana ma waena o nā ʻano ʻekolu. Ma ke ʻano o ka mana o ka hoʻokele waena o ka hoʻokele, ʻoi aku ka ikaika a me ka maikaʻi keu ke hele i kahi piʻi. Akā e like me ka mea i manaʻo ʻia, hiki mai me kahi kumukūʻai ʻoi aku ka nui inā koi ia i ka mālama liʻiliʻi. 
Kāhea ka ʻōnaehana lepili kūloko ʻo Bafangs i kēia ʻo MM G510.1000, a ke hoʻolālā nei ia i nā hoʻomaikaʻi ʻana ma luna o kaʻu hoʻokele punahele, ʻo BBSHD. ʻO ka BBSHD kahi pahu e heʻe i loko o kahi kiʻi āu e makemake ai, akā koi ka Ultra Max i kahi pūpū kuleana e kau iā ia (e ʻike ma lalo).

ʻO ka mea mua i puka i ka mea nānā maʻamau ʻo ka ʻoi aku ka nui o ka mika o ka Ultra. Hoʻonui kēia i ka nui o ka leverage a nā mākēneki e hana ai i ka wili ʻana i ka rotor, me ka ʻole o nā watts hou i hoʻopili ʻia iā ia, ke hoʻohālikelike ʻia i nā watts like i hoʻopili ʻia i kahi motika diameter liʻiliʻi me ka nui keleawe like. ʻO ka mea ʻē aʻe e kōkua ai i kēia ka hopena, no ka mea ʻoi aku ka wikiwiki o ka "magnet magnet tangential" no kahi RPM i hāʻawi ʻia.
He aha kēlā manaʻo ... e hoʻopili ka mea hoʻokele i nā amps kiʻekiʻe i nā electromagnets i ka stator a wili wikiwiki nā mākēneki paʻa i ka rotor a hiki i ka wikiwiki o nā motika, ʻo ka mea i kapa ʻia ʻo "Kv" o ka wili (kaomi ma aneʻi no "ʻenehana ʻenehana, e aʻo i nā huaʻōlelo").

ʻO ka wikiwiki e hala nā mākēneki i kēlā me kēia, ʻo ka pōkole o nā pulse o nā watts ... i hoʻopili ʻia i nā electromagnets. Ma ka hoʻohana ʻana i nā puʻupuʻu liʻiliʻi 'hiki' ke hāʻawi i ka mana huina like i hoʻopili ʻia, hoʻohālikelike ʻia me ka hoʻohana ʻana i nā kuʻikuʻu ʻoi aku ka lōʻihi, akā… me ka hoʻohana ʻana i nā lōʻihi ʻoi aku ka lōʻihi o nā pulsa e hoʻomehana ai ka MOSFET i ka mea mālama, a me nā electromagnets hoʻi i ka stator.

E makaʻala i ka ʻoi loa o ka stator ʻo Ultra Max ma mua o ka BBSHD, akā ʻoi aku ka nui o ke anawaena i ka nui o nā keleawe.

ʻO kekahi mea pono e hoʻomaopopo ʻia ʻo BBS02 i ke kiʻi ma luna e hoʻohana nei i ka mea i kapa ʻia ʻo “Surface Permanent Magnets” / SPM ma ka rotor, a ʻo ka Ultra (me BBSHD) e hoʻohana i kahi kaila e hoʻokomo i nā mākēneki i kahi mamao iki mai ka ʻili o ka rotor. ʻIke pinepine ʻia kēia kaila i kēia mau lā, a ua kapa ʻia ʻo “Mākēneki paʻa paʻa” motika / IPM.

ʻAe kēia hoʻolālā i nā mākēneki e holo ʻoi aku, ʻo ia ka mea nui no ka mea ʻo kekahi o nā palena i ka nui o nā amp e hiki i kahi motika ke hoʻohana ʻo ia ka wela i hoʻokumu ʻia e "nā wai kahe". Hana ʻia ke kumu stator mai kahi papa o nā papa kila lahilahi i mea e hōʻemi ai i nā kahe eddy, i hoʻokumu ʻia i kēlā me kēia manawa ke hele wikiwiki ʻia kahi metala ferrous i loko o kahi māla magnet.

Ke hoʻohana nei i kahi stator-core i hana ʻia mai nā papa laminated lahilahi (i uhi ʻia me ka lacquer e hoʻokaʻawale uila i hoʻokahi papa mai kahi ʻē aʻe) he ala waiwai ke kumu kūʻai e hoʻokō ai i kahi palena o nā wela o kēia manawa, akā… ʻaʻole like me ka stator-core laminated , nā mākēkē i nā ʻāpana paʻa o ka hao. Me nā hoʻolālā motika SPM kahiko, lilo ke kino o ka magnet iā ia i kumu no ka wela neoneo.

Me kahi IPM, e "magnetize" nā mākēneki paʻa i ka ʻāpana lahilahi o ke kila ma waena o lākou a me nā electromagnets i ka stator. Mālama kēia i ka ikaika ma ka ʻume mākenēki i ka hakahaka o ke ea ma kahi pae ʻae ʻia, ʻoiai ke kau nei i nā mākēneki kū mau i kahi mamao pōkole mai ka ʻāpana ea. Hiki i nā mākēneki paʻa mau ke lilo i ko lākou mana magnet inā wela loa lākou, no laila… ma ka hana ʻana i kēia, hiki iā ʻoe ke hoʻohana i nā amps "wā pōkole" ʻoi aku ka nui me ka ʻole o ka hoʻomehana ʻana i nā mākēneki.
