Me ka hoʻomau mau ʻana i ka pono kaʻa, ʻike ʻia nā rotors pani pani ʻia e nā mea hana kaʻa. No ka meaʻekolu ʻāpana asynchronous motors, ma muli o ka noho ʻana o ka stator a me ka rotor grooves, e hoʻohua ka hoʻololi ʻana i ka pau ʻana o ka pulsation. Inā hoʻohana ka rotor i ka pahu pani paʻa, ua pōkole ka ea ea kūpono, a ua nāwaliwali ka pulsation o ka ea gap magnetic field, no laila e hōʻemi ana i ka hiki o ka excitation a me ka nalowale o ke kahua magnetic harmonic, e kōkua ana i ka hoʻomaikaʻi ʻana i ka hana o ka kaʻa.
ʻO ke kuhikuhi ʻana o ka Arch kahi mea koʻikoʻi o ka rotor slot i pani ʻia, i ka hihia o ke ʻano ʻano rotor slot like, ʻo ke koho ʻana o ke kiʻekiʻe o nā alahaka ʻokoʻa e loaʻa nā degere like ʻole o ka hopena i ka hana kaʻa. Hoʻopaʻa ʻia ka pahu rotor ma muli o ka ʻike ʻole ʻia, paʻakikī ka nānā ʻana i ka maʻemaʻe, maʻalahi ke ʻike ʻia ka pilikia sawtooth huna, hoʻonui i nā mea hiki ʻole ke kāohi.
Ka hoohana ana opani ʻia ʻo rotor, oiai e hoemi ana i ka poho a me ka hao hao o ke kaa, e hoonui i ka leakage reactance rotor, ka hopena i ka emi ana o ka mana kumu, hoonui i ka stator ukana i keia manawa, hoonui stator poho; hoʻomaka ka torque a me ka hoʻomaka ʻana i kēia manawa, ua hoʻonui ʻia ka nui o ka huli ʻana. No laila, i ka wā e hoʻohana ai i ka slot i pani ʻia, pono e noʻonoʻo ʻia nā loli i nā ʻikepili hana like ʻole i ka manawa like e hoʻonui ai i ka hana holoʻokoʻa o ka kaʻa.
He aha ke ʻano o ka ʻenekini induction?
ʻO ka motika induction e pili ana i kahi ʻano stator a me ka rotor e ka electromagnetic induction, inductance i kēia manawa i ka rotor e ʻike ai i ka mīkini hoʻololi uila electromechanical. ʻO ka stator o kahi kaʻa induction he ʻekolu ʻāpana: stator core, stator winding a me ka noho. Aia ka rotor i ka rotor core, rotor winding and rotor shaft. ʻO ke kumu rotor, ʻo ia hoʻi kahi ʻāpana o ka kaapuni magnetic nui, i hana maʻamau ʻia me nā ʻāpana kila silika i hoʻopaʻa ʻia ma ka mānoanoa o 0.5mm, a ua paʻa ke kumu ma ke kumu rotor a i ʻole bracket rotor. He ʻano cylindrical ka rotor holoʻokoʻa.
ʻO kanā wili rotorua māhele ʻia i ʻelua ʻano: cage a me wirewound. Ma lalo o nā kūlana maʻamau, ʻoi aku ka haʻahaʻa a i ʻole ka kiʻekiʻe o ka wikiwiki o ka rotor o kahi kaʻa induction ma mua o ka wikiwiki o ke kahua magnetic rotating (synchronous speed), no laila ua kapa ʻia nā motika induction "asynchronous motors". Ke hoʻololi ʻia ka ukana o kahi kaʻa induction, e loli ka wikiwiki o ka rotor a me ka ʻokoʻa o ka rotation rate, no laila e hoʻololi ka mana uila, ka manawa a me ka electromagnetic torque i ka conductor rotor e hoʻololi i nā pono o ka ukana. E like me ka maikaʻi a maikaʻi ʻole paha o ka rotation a me ka nui o ka induction motor, ʻekolu mau ʻano o ka hana ʻana: motor, generator a me electromagnetic brake.
