Ke kumu o ka mokini asynchronous

Noi o Asynchronous Motor

ʻO nā motika asynchronous e hana ana e like me nā kaʻa uila. Ma muli o ka hoʻoulu ʻia ʻana o ka manawa wili rotor, ua kapa ʻia ʻo ia he motika induction. ʻO nā motika Asynchronous ka mea i hoʻohana nui ʻia a koi nui ʻia i nā ʻano kaʻa a pau. Ma kahi o 90% o nā mīkini i hoʻohana ʻia e ka uila ma nā ʻāina like ʻole he mau kaʻa asynchronous, kahi o nā mīkini asynchronous liʻiliʻi ma mua o 70%. I ka nui o ka ukana o ka ʻōnaehana mana, ʻo ka hoʻohana ʻana i ka uila o nā kaʻa asynchronous e helu no ka hapa nui. Ma Kina, ʻoi aku ka nui o ka hoʻohana ʻana i ka uila o nā kaʻa asynchronous ma mua o 60% o ka nui o ka ukana.

ʻO ka manaʻo o ka motika asynchronous

 

ʻO ka motika asynchronous kahi motika AC nona ka ratio o ka wikiwiki o ka haʻawe i ka alapine o ka pahu pili ʻaʻole ia he waiwai mau. ʻO ka motika induction he motika asynchronous me hoʻokahi pūʻulu o nā wiliwili i pili i ka lako mana. Inā ʻaʻole i hoʻokumu i ka hoʻomaopopo ʻole a me ka huikau, hiki ke kapa ʻia nā motika induction ma ke ʻano he asynchronous motors. Wahi a ka IEC maʻamau, ua hoʻohana maoli ʻia ka huaʻōlelo "induction motor" ma ke ʻano he synonym no "asynchronous motor" ma nā ʻāina he nui, aʻo nā ʻāina ʻē aʻe e hoʻohana wale i ka huaʻōlelo "asynchronous motor" e hōʻike i kēia mau manaʻo ʻelua.

Ke kumu o ka mokini asynchronous
Ma hope o ka hoʻohana ʻia ʻana o ka volta symmetrical i ka wili stator o kahi kaʻa asynchronous ʻekolu-phase, e hana ʻia kahi mākēneki ea-awāwa kaʻa, a ʻoki ka mea hoʻokele wili rotor i ke kahua magnetic e hoʻohua ai i kahi mana hoʻoulu. Hoʻokumu ʻia kahi au rotor ma muli o ke kaapuni pōkole o nā wili rotor. ʻO ka launa pū ʻana ma waena o ka manawa rotor a me ke kahua magnetic gap e hoʻohua i ka torque electromagnetic, kahi e hoʻohuli ai i ka rotor. Pono e emi ka māmā o ka kaʻa ma mua o ka wikiwiki synchronous o ka māla magnetic, no ka mea ma kēia ala wale nō e hiki ai i ka mea hoʻokele rotor ke hoʻoulu i kahi mana uila e hoʻohua i ka rotor a me ka electromagnetic torque. No laila ua kapa ʻia ka mīkini he mīkini asynchronous, i kapa ʻia hoʻi he motika induction.
