Nā mea pono loea o ka motika eVTOL

1. Nā ʻano loea omotika eVTOL

In uila i hoʻolaha ʻiaka propulsion, hoʻokele nā ​​​​motika i nā propeller a i ʻole nā ​​​​peʻahi he nui ma nā ʻēheu a i ʻole fuselage e hana i kahi ʻōnaehana propulsion e hāʻawi ana i ka hoʻoikaika i ka mokulele. Hoʻopilikia pololei ka nui o ka mana o ka motika i ka hiki ke ukana o ka mokulele. ʻO ka hiki ke hoʻopuka mana, ka hilinaʻi a me ka hoʻololi ʻana i ke kaiapuni o ka motika he mau mea nui e hoʻoholo ai i nā ʻano loli a me ka palekana o ka mokulele uila. He ʻokoʻa ke koho ʻana o nā kaʻa uila, nā drones a me nā motika eVTOL ma muli o nā kumukūʻai like ʻole, nā hiʻohiʻona noi a me nā kumu ʻē aʻe [1].

1) Nā kaʻa uila: ʻoi aku ka makeneka paʻanā motika synchronous,hiki i nā motika magnet mau loa me ka pono kiʻekiʻe a me ka torque kiʻekiʻe ke hāʻawi i kahi ʻike hoʻokele maikaʻi aʻe. I ka manawa like, hiki i ka nui o ka mana o nā motika magnet mau loa ke kōkua i nā kaʻa uila e loaʻa ka mana kiʻekiʻe ma lalo o ka nui like.

(2) UAV: ​​hoʻohana pinepine ʻia me ka brushlessMotika DC.He haʻahaʻa ke kaumaha a me ka walaʻau o ka motika brushless DC, a he haʻahaʻa ke kumukūʻai mālama, kūpono ia no nā koi lele o nā UAV; ʻO ka lua, ʻoi aku ka wikiwiki o ka motika brushless DC, kūpono ia no nā pono lele wikiwiki o nā drones. No ka laʻana, hoʻohana ʻo DJI i nā motika brushless.

(3) eVTOL: Nā koi kiʻekiʻe no ka pono o ka motika a me ka nui o ka torque, ʻo ka motika synchronous magnet mau loa he hopena hoʻohiki loa ia no ka ʻōnaehana mana propulsion uila, no ka mea, he kiʻekiʻe ka hoʻohana ʻana o ka motika magnet mau loa axial flux i ka hakahaka radial, a he pono ka nui o ka mana a me ka nui o ka torque i ka hihia o ka ratio diameter lōʻihi liʻiliʻi. Hoʻohana nā mokulele VTOL uila o kēia manawa, e like me Joby S4 a me Archer Midnight, i nā motika synchronous magnet mau loa [1].

Hōʻike ke kiʻi ma lalo nei i ke kiʻi ao o ka ikaika hoʻokomo magnetic rotor paʻa o ka motika flux axial single-rotor single-stator.

ʻO ke kiʻi ma lalo nei he hoʻohālikelike o nā mokulele uila a me nā ʻāpana motika kaʻa uila

2. ʻAno hoʻomohala motika eVTOL
I kēia manawa, ʻo ke ʻano nui o ka hoʻomohala ʻana o ka ʻōnaehana mana eVTOL ka hoʻemi ʻana i ke kaumaha o ke ʻano o ka motika a me ke kaumaha kōkua o ka ʻōnaehana hoʻoluʻu ma o ka hoʻomaikaʻi ʻana i ka ʻenehana hoʻolālā electromagnetic, ʻenehana hoʻokele thermal a me ka ʻenehana māmā, a hoʻomaikaʻi mau i ka nui o ka mana o ka motika a me ka mana hoʻopuka mana o nā ʻano kūlana like ʻole. Wahi a ka "Research and Development of Flying cars and Key Technologies", ua hiki i ka motika propulsion aviation ke hana i ka nui o ka mana i helu ʻia o ke kino motika ma mua o 5kW/kg ma ka hoʻohana ʻana i nā mea insulation me nā palena mahana kiʻekiʻe, nā mea magnet mau loa me ka nui o ka ikehu magnetic kiʻekiʻe a me nā mea kūkulu māmā. Ma ka hoʻomaikaʻi ʻana i ka hoʻolālā ʻano electromagnetic o ka motika, e like me ka hoʻohana ʻana i ka Halbach magnetic array, ʻaʻohe hale hao, Litz wire winding a me nā ʻenehana ʻē aʻe, a me ka hoʻomaikaʻi ʻana i ka hoʻolālā hoʻoheheʻe wela o ka motika, manaʻo ʻia e hiki i ka nui o ka mana i helu ʻia o ke kino motika ke hiki i 10kW/kg i ka makahiki 2030, a ʻoi aku ka nui o ka mana i helu ʻia ma mua o 13kW/kg i ka makahiki 2035 [1].

3. Hoʻohālikelike ʻana o nā ala uila maʻemaʻe a me nā ala hybrid
Ke hoʻohālikelike ʻia me ke ala uila maʻemaʻe a me ke ala hybrid, mai ke koho ʻana o nā mea hana pili i kēia manawa, ua hoʻokumu nui ʻia ka papahana eVTOL kūloko ma ka papahana uila maʻemaʻe, i kaupalena ʻia e ka nui o ka ikehu o nā pila lithium-ion, a ʻo ka mana haʻahaʻa o ka eVTOL ka hiʻohiʻona pae maikaʻi loa o ka ʻenehana propulsion uila maʻemaʻe. Ma waho, ua hoʻonohonoho mua kekahi mau mea hana i ka hoʻolālā hybrid, a ua alakaʻi i nā pōʻai he nui o ka hoʻāʻo ʻana a me ka hana hou ʻana. E like me ka mea i ʻike ʻia mai ka papa ma lalo nei, ʻoi aku ka ikaika o ka papahana hybrid i ke Angle hoʻomanawanui, a hiki ke hoʻokō i nā noi hou aʻe i ke kūlana o ka mamao waena a me ke kaʻa haʻahaʻa i ka wā e hiki mai ana [1].
