Introduction: Ma ke kamaʻilio ʻana i nā kaʻa ikehu hou, hiki iā mākou ke lohe mau i ka poʻe loea e kamaʻilio ana e pili ana i "ʻekolu-electrical system", no laila he aha ka manaʻo o "ʻekolu-electrical system"? No nā kaʻa ikehu hou, ʻo ka ʻōnaehana uila ʻekolu e pili ana i ka pā mana, kaʻa kaʻa a me ka ʻōnaehana uila. Hiki ke ʻōlelo ʻia ʻo ka ʻōnaehana uila ʻekolu ka mea nui o ka kaʻa ikehu hou.
kaʻa kaʻa
ʻO ke kaʻa ke kumu mana o ke kaʻa ikehu hou. E like me ke ʻano a me ka loina, hiki ke hoʻokaʻawale ʻia ka kaʻa i ʻekolu mau ʻano: DC drive, hoʻonohonoho magnet mau loa, a me AC induction. Loaʻa nā ʻano ʻokoʻa o nā ʻano motika like ʻole.
1. DC kaʻa kaʻa kaʻa, kona stator mea he mau magnet, a me ka rotor ua pili i ka pololei au. Hōʻike ka ʻike physics o ke kula kiʻekiʻe iā mākou e hoʻokau ʻia ka mea hoʻokele ikaika i ka ikaika ampere ma ke kahua magnetic, a laila e hoʻohuli ai ka rotor. ʻO nā mea maikaʻi o kēia ʻano kaʻa ke kumu kūʻai haʻahaʻa a me nā koi haʻahaʻa no ka ʻōnaehana hoʻokele uila, ʻoiai ʻo ka hemahema ʻo ia ka nui a me ka nāwaliwali o ka hana mana. ʻO ka maʻamau, e hoʻohana nā scooter uila maʻemaʻe haʻahaʻa i nā motika DC.
2. ʻO ka mīkini paʻa paʻa synchronous he ʻoiaʻiʻo DC ka motika, no laila, ua like kona loina hana me ka motika DC. ʻO ka ʻokoʻa, ua hānai ʻia ka motika DC me ka nalu square, aʻo ka mīkini paʻa synchronous magnet e hānai ʻia me ka nalu sine. ʻO nā mea maikaʻi o nā motor synchronous magnet mau loa ka hana mana kiʻekiʻe, hilinaʻi maikaʻi loa, a me ka liʻiliʻi liʻiliʻi. ʻO ka hemahema, ʻoi aku ka kiʻekiʻe o ke kumukūʻai, a aia kekahi mau koi no ka ʻōnaehana uila uila.
3. ʻOi aku ka paʻakikī o nā motika induction ma ke kumumanaʻo, akā hiki ke hoʻokaʻawale ʻia i ʻekolu mau ʻanuʻu: ʻo ka mua, pili nā wili ʻekolu-phase o ke kaʻa i ke ʻano o kēia manawa e hoʻohua ai i kahi māla magnetic rotating, a laila ka rotor i haku ʻia me nā coils pani. ua ʻoki ʻia i loko o ke kahua mākēneki e hoʻohuli ʻia ana nā laina o ke kahua magnetic i ke au i hoʻokomo ʻia, a i ka hopena, ua hoʻokumu ʻia ka ikaika Lorentz ma muli o ka neʻe ʻana o ka hoʻoili uila i loko o ka māla magnetic, kahi e hoʻoulu ai ka rotor. hoʻohuli. No ka mea, e huli mua ana ke kahua magnetic i loko o ka stator a laila e huli ka rotor, ua kapa ʻia kekahi kaʻa induction he motor asynchronous.
ʻO ka maikaʻi o ka mīkini induction ʻo ia ka haʻahaʻa o ke kumukūʻai hana, a maikaʻi hoʻi ka hana mana. Manaʻo wau hiki i nā mea a pau ke ʻike i ka hemahema. No ka mea, pono ia e hoʻohana i ke au hou, loaʻa iā ia nā koi kiʻekiʻe ma ka ʻōnaehana mana uila.
Kahiko mana
ʻO ka puʻupuʻu mana ke kumu ikehu no ka hoʻokele ʻana i ke kaʻa. I kēia manawa, ʻike nui ʻia ka pā uila e nā mea maikaʻi a maikaʻi ʻole. Aia nā lithium cobalt oxide, lithium ternary, lithium manganate a me ka lithium iron phosphate. ʻO Yuan lithium a me ka lithium iron phosphate bateria.
I waena o lākou, he haʻahaʻa ke kumu kūʻai o nā pākaukau lithium iron phosphate, kūpaʻa maikaʻi a me ke ola lōʻihi, aʻo nā hemahema he haʻahaʻa haʻahaʻa haʻahaʻa a me ke ola pākaukau koʻikoʻi i ka hoʻoilo. ʻO ka pākaukau lithium ternary ka mea kū'ē, ʻo ka pōmaikaʻi he haʻahaʻa haʻahaʻa haʻahaʻa, a ʻo ka hemahema ka paʻa ʻole a me ke ola.
Pūnaehana mana uila
ʻO ka ʻōnaehana hoʻokele uila he huaʻōlelo maʻamau. Inā hoʻokaʻawale ʻia, hiki ke hoʻokaʻawale ʻia i ka ʻōnaehana hoʻokele kaʻa, ka ʻōnaehana hoʻokele kaʻa, a me ka ʻōnaehana hoʻokele pila. ʻO kahi hiʻohiʻona nui o nā kaʻa ikehu hou ʻo ia ka pili pono ʻana o nā ʻōnaehana hoʻokele uila i kekahi i kekahi. Loaʻa i kekahi mau kaʻa kahi ʻōnaehana hoʻokele uila e hoʻokele i nā lako uila a pau ma ke kaʻa, no laila ʻoi aku ka maikaʻi o ke kāhea ʻana iā lākou hui.
No ka mea, ʻo ka ʻōnaehana uila ʻekolu he mea nui ia o nā kaʻa ikehu hou, inā ua pōʻino ka ʻōnaehana uila ʻekolu, ʻaʻohe mea kānalua ke kiʻekiʻe loa ke kumukūʻai no ka hoʻoponopono ʻana a i ʻole ke pani hou ʻana, no laila e hoʻomaka ana kekahi mau hui kaʻa i kahi ola ʻekolu mau uila. kulekele hōʻoia. ʻOiaʻiʻo, ʻaʻole maʻalahi ka haki ʻana o ka ʻōnaehana uila ʻekolu, no laila e ʻaʻa nā hui kaʻa e ʻōlelo i kahi palapala hōʻoia ola.
