ʻO nā motika AC, ʻoi aku ka hana kiʻekiʻeʻekolu ʻāpana asynchronousmotors, hoʻohana nui ʻia i nā noi ʻoihana a me nā ʻoihana ma muli o ko lākou hilinaʻi a me ka hana. Uaʻikeʻia kēia mau motika no ko lākou hiki ke hana i ka wikiwiki mau, e kūpono iā lākou no ka nui o nā noi.
ʻO kekahi o nā noi nui oNā motika ACaia i loko o ka ʻoihana ʻoihana, kahi e hoʻohana ʻia ai lākou i nā mīkini e like me nā pumps, compressors, conveyors a me nā mea pā. ʻO ka maikaʻi kiʻekiʻe o nā motika asynchronous ʻekolu-phase e kūpono iā lākou no ka hana mau ʻana i nā ʻoihana ʻenehana kahi mea koʻikoʻi ka mālama ʻana i ka ikehu a me ka hilinaʻi. Hoʻohana pū ʻia kēia mau kaʻa i nā kaʻina hana kahi i koʻikoʻi ai ka mana pololei o ka wikiwiki a me ka torque i ka hana ʻana o nā huahana.
Ma ka ʻoihana kalepa, hoʻohana ʻia nā motika AC i nā ʻōnaehana hoʻomehana, ventilation, a me ka ea ea (HVAC) a me nā mea hoʻonaninani a me nā mea hoʻoluʻu. ʻO kahana kiʻekiʻeʻO kēia mau kaʻa e kōkua i ka mālama ʻana i ka ikehu a hōʻemi i nā kumukūʻai hana no nā hale kūʻai a me nā mea pono. Hoʻohui ʻia, hoʻohana ʻia nā kaʻa AC i nā lako kīhini kalepa, nā mea hoʻokiʻekiʻe, nā escalators, a me nā ʻōnaehana mechanical ʻē aʻe e pono ai ka hana kaʻa pono.
ʻO kekahi noi nui o nā kaʻa AC i ka ʻoihana kaʻa, kahi i hoʻohana ʻia ai i nā kaʻa uila, nā kaʻaahi, a me nā ʻano ʻano o ka halihali lehulehu. ʻO ka maikaʻi kiʻekiʻe o kēia mau kaʻa he mea maikaʻi loa ia no nā kaʻa uila, kahi e mālama ai i ka ikehu a me ka laulā nā kumu nui. He mea koʻikoʻi nō hoʻi nā kaʻa AC i nā ʻōnaehana propulsion o nā moku a me nā moku kai, a he mea koʻikoʻi ko lākou hilinaʻi a me ka hana no ka hana palekana a maikaʻi.
I ka ʻāpana ikehu hou, hoʻohana ʻia nā motika AC i nā turbines makani a me nā mea hana hydroelectric e hoʻololi i ka ikehu mechanical i ka ikehu uila. ʻO ka hana kiʻekiʻe o kēia mau kaʻa e kōkua i ka hoʻomaikaʻi ʻana i ka hopena o ka ikehu holoʻokoʻa a me ka hana ʻana o nā ʻōnaehana ikehu hou, e hoʻolilo iā lākou i ʻāpana o ka hana mana hoʻomau.
No ka hōʻuluʻulu ʻana, hoʻohana ʻia nā motika AC, ʻoi aku ka maikaʻi o nā motika asynchronous ʻekolu-phase, i nā ʻoihana like ʻole a me nā kula. ʻO kā lākou hilinaʻi, hana a me ka hiki ke mālama i ka ikehu he mea nui ia i ka ʻenehana, kalepa, ka lawe ʻana a me nā noi ikehu hou, e hāʻawi ana i ka pono a me ka hoʻomau o nā ʻenehana hou.
