Me ka hoʻolaha ʻana o ka mana o ka mana alapine, ua maʻalahi ka pilikia o ka hoʻomaka ʻana o ka kaʻa, akā no ka lako mana maʻamau, ʻo ka hoʻomaka ʻana o ka squirrel-cage rotor asynchronous motor he pilikia mau.Mai ka nānā ʻana i ka hana hoʻomaka a me ka holo ʻana o ka motor asynchronous, hiki ke ʻike ʻia i mea e hoʻonui ai i ka torque hoʻomaka a hoʻemi i ka manawa i ka wā e hoʻomaka ai, koi ʻia ke kūʻē o ka rotor;oiai e holo ana ka motika, i mea e hoemi ai i ka pau ana o ke keleawe rotor a me ka hooikaika ana i ka pono o ka moto, pono ke ku'e o ka rotor e li'ili'i Kekahi;he mea kue keia.

No ka mīkini rotor ʻeha, no ka mea hiki ke hoʻopili ʻia ke kūʻē i ka moʻo i ka hoʻomaka, a laila ʻoki ʻia i ka manawa o ka hana, ua hoʻokō maikaʻi ʻia kēia koi.Eia nō naʻe, paʻakikī ke ʻano o ka ʻeha asynchronous motor, kiʻekiʻe ke kumukūʻai, a ʻaʻole kūpono ka mālama ʻana, no laila ua kaupalena ʻia kāna noi i kekahi ʻano;ʻO nā mea pale, ʻoiai e holo ana me nā mea pale liʻiliʻi.Loaʻa kēia hana hoʻomaka ʻana i nā motika rotor slot hohonu a me ka hale squirrel cage ʻelua.I kēia lā, ua komo ʻo Ms. i ke kamaʻilio ʻana e pili ana i ka motika rotor slot hohonu.

ʻO ka mīkini ʻokoʻa asynchronous slot hohonu

I mea e hoʻoikaika ai i ka hopena o ka ʻili, ʻo ke ʻano o ka groove o ka deep groove asynchronous motor rotor he hohonu a haiki, a ʻo ka ratio o ka hohonu o ka groove a me ka laula o ka groove aia ma ka laulā o 10-12.Ke hele nei ke au i loko o ka pahu rotor, ʻoi aku ka nui o ka leakage magnetic flux e hui pū ana me ka lalo o ka pahu ma mua o ka hui ʻana me ka ʻāpana notch.No laila, inā manaʻo ʻia e māhele ʻia ka pā e kekahi mau mea liʻiliʻi.

 

I ka wā e hoʻomaka ai, no ka mea he kiʻekiʻe ke alapine o ka manawa rotor a nui ka leakage reactance, ʻo ka hāʻawi ʻana o kēia manawa i kēlā me kēia conductor liʻiliʻi e hilinaʻi ʻia i ka leakage reactance, a ʻo ka nui o ka leakage reactance, ʻoi aku ka liʻiliʻi o ka leakage o kēia manawa.Ma kēia ala, ma lalo o ka hana o ka mana like i hoʻoulu ʻia e ka flux magnetic nui o ka ea ea, ʻo ka nui o kēia manawa ma ka pā kokoke i lalo o ka slot e liʻiliʻi loa, a ʻo ka kokoke loa i ka slot, ʻoi aku ka nui o kēia manawa. mānoanoa.

Ma muli o ka hopena o ka ʻili, ma hope o ka hoʻopili ʻia ʻana o ka hapa nui o kēia manawa i ka ʻaoʻao o luna o ka pahu alakaʻi, he liʻiliʻi loa ke kuleana o ka pahu alakaʻi ma lalo o ke awāwa.E hoʻokō i nā koi o ke kū'ē nui i ka wā e hoʻomaka ai.Ke hoʻomaka ka kaʻa a holo maʻamau ka mīkini, no ka mea he haʻahaʻa loa ke alapine o ka rotor, ʻoi aku ka liʻiliʻi o ka leakage reactance o ka wili rotor ma mua o ke kūpaʻa rotor, no laila ʻo ka hāʻawi ʻana i kēia manawa i nā conductors liʻiliʻi i ʻōlelo ʻia ma mua. hoʻoholo ʻia e ke kūʻē.

 

Ma muli o ka like o ke kū'ē o kēlā me kēia alakaʻi liʻiliʻi, e māhele like ʻia ke ʻano o ka pā, no laila e nalowale ka hopena o ka ʻili, a liʻiliʻi ke kūʻē o ka pahu rotor, kokoke i ke kūpaʻa DC.Hiki ke ʻike ʻia ka emi ʻana o ke kūpaʻa rotor i ka hana maʻamau, a laila e ʻoluʻolu i ka hopena o ka hōʻemi ʻana i ka hoʻohana keleawe a me ka hoʻomaikaʻi ʻana i ka pono.

He aha ka hopena o ka ʻili?Ua kapa ʻia ka hopena ʻili i ka hopena ʻili.Ke hele ka au i loko o ka conductor, e noʻonoʻo ke au i ka ʻili o ka conductor a kahe.Kapa ʻia kēia hanana ka hopena ʻili.Ke holo nei ka manawa a i ʻole ka uila i loko o kahi conductor me nā electrons kiʻekiʻe aʻe, e hōʻuluʻulu lākou ma ka ʻili o ka conductor holoʻokoʻa ma mua o ka puʻunaue like ʻana i ka ʻāpana cross-sectional o ka conductor holoʻokoʻa.

ʻAʻole pili wale ka hopena o ka ʻili i ke kūpaʻa rotor, akā pili pū kekahi i ka reactance leakage rotor.Mai ke ala o ke kahe leakage slot, hiki ke ʻike ʻia ʻo ka hele ʻana o kēia manawa i kahi mea lawe liʻiliʻi e hoʻopuka wale i ka leakage mai ka mea lawe liʻiliʻi a hiki i ka notch, ʻaʻole e hoʻohua i ka leakage flux mai ka conductor liʻiliʻi a i lalo o ka pahu. slot.No ka mea, ʻaʻole pili ka hope i kēia au.Ma kēia ala, no ka like o ka nui o kēia manawa, ʻoi aku ka kokoke i ka lalo o ka slot, ʻoi aku ka nui o ka leakage flux e hoʻopuka ʻia, a ʻo ka kokoke loa i ka wehe ʻana o ka slot, ʻo ka liʻiliʻi o ka leakage flux e hana ʻia.Hiki ke ʻike ʻia ke kaomi ʻana o ka ʻili i ke au i loko o ka pā a hiki i ka notch, e emi ana ka leakage magnetic flux i hoʻokumu ʻia e ia manawa like, no laila e emi iho ka reactance leakage slot.No laila, hoʻonui ka hopena o ka ʻili i ke kū'ē rotor a hoʻemi i ka reactance leakage rotor.

ʻO ka ikaika o ka hopena o ka ʻili e pili ana i ke alapine o ka manawa rotor a me ka nui o ke ʻano slot.ʻO ke kiʻekiʻe o ke alapine, ʻoi aku ka hohonu o ke ʻano o ka slot, a ʻoi aku ka nui o ka hopena o ka ʻili.ʻO ka rotor like me nā alapine like ʻole e loaʻa nā hopena like ʻole o ka hopena ʻili, a no laila e ʻokoʻa nā ʻāpana rotor.Ma muli o kēia, pono e hoʻokaʻawale ʻia ke kūʻē rotor a me ka leakage reactance i ka wā maʻamau a me ka hoʻomaka ʻana a ʻaʻole hiki ke huikau.No ke alapine like, ikaika loa ka hopena o ka ʻili o ka rotor groove hohonu, akā ʻo ka hopena o ka ʻili ke loaʻa kekahi ʻano o ka mana ma ke ʻano maʻamau o ka rotor cage squirrel.No laila, no ka rotor squirrel-cage me kahi hoʻolālā maʻamau, pono e helu kaʻawale nā ​​ʻāpana rotor i ka hoʻomaka ʻana a me ka hana.

ʻO ka reactance leakage rotor o ka motika asynchronous slot hohonu, no ka mea he hohonu loa ke ʻano o ka slot rotor, ʻoiai ua hoʻemi ʻia e ka hopena o ka ʻili, ʻoi aku ka nui ma mua o ka reactance squirrel cage rotor leakage reactance ma hope o ka hoʻemi ʻana.No laila, ʻoi aku ka haʻahaʻa o ka mana mana a me ka torque kiʻekiʻe o ka mīkini slot hohonu ma mua o ka mea o ka motika squirrel cage maʻamau.
