ʻAʻole ʻokoʻa ma waena o kahi kaʻa a me kahi kaʻa uila?

Aia ka ʻokoʻa nui ma waena o kahi kaʻa a me kahi kaʻa uila. I kēia lā e nānā mākou i kekahi o nā ʻokoʻa ma waena o nā mea ʻelua a e ʻike hou i ka ʻokoʻa ma waena o lākou.

 

He aha ka mokini uila?

ʻO ke kaʻa uila he mea electromagnetic e hoʻohuli a hoʻouna i ka ikehu uila e like me nā kānāwai o ka hoʻokomo electromagnetic.

Hōʻike ʻia ke kaʻa e ka leka M ma ka kaapuni (D i ka maʻamau kahiko) a ʻo kāna hana nui ka hana ʻana i ka torque hoʻokele ma ke ʻano he kumu mana no nā mea hana a i ʻole nā ​​mīkini like ʻole, ʻoiai ke hōʻike ʻia ka generator e ka leka G i ke kaapuni a ʻo kāna hana nui ka hoʻololi ʻana i ka ikehu uila i ka ikehu mechanical.

一. Māhele kaʻa a me ka hoʻokaʻawale ʻana

1. E like me ke 'ano o ka hana mana lako: hiki ke maheleia iMotor DCa me ka motika AC.

 

2. E like me ka hoʻolālā a me ka loina hana, hiki ke mahele ia iMotor DC, kaʻaʻa asynchronous a me ka mīkini hoʻopono.

 

3. E like me ka hoʻomaka 'ana a me ka holo 'ana: capacitor hoʻomaka hoʻokahi-phase asynchronous kaʻa, capacitor holo hoʻokahi-phase asynchronous kaʻa, capacitor hoʻomaka a me ka holo hoʻokahi-phase asynchronous kaʻa a me ka māhele hoʻokahi-phase asynchronous kaʻa.

 

4. E like me ke kumu, hiki ke hoʻokaʻawale ʻia ke kaʻa i: motor no ka hoʻokele a me ka moto no ka mana.

 

5. E like me ke ʻano o ka rotor: cage induction motor (ka maʻamau kahiko i kapa ʻia ʻo squirrel cage induction motor) a me ka ʻeha rotor induction motor (ka maʻamau kahiko i kapa ʻia ʻo wound asynchronous motor).

 
6. E like me ka wikiwiki o ka hana, hiki ke hoʻokaʻawale ʻia i: nā mīkini kiʻekiʻe kiʻekiʻe, nā kaʻa haʻahaʻa haʻahaʻa, nā kaʻa kaʻa mau a me nā mīkini hoʻokele wikiwiki. Hoʻokaʻawale ʻia nā kaʻa haʻahaʻa haʻahaʻa i nā kaʻa kaʻa, nā kaʻa hoʻemi electromagnetic, nā kaʻa torque a me nā kaʻa kaʻa synchronous claw-pole.
 

二. He aha ke kaʻa uila

 

ʻO ke kaʻa uila (Motor) he mea hana e hoʻololi i ka ikehu uila i ikehu mechanical. ʻO ia ka hoʻohana ʻana i nā coils ikaika (ʻike pū ʻia ʻo stator windings) e hoʻohua i kahi māla magnetic rotating a hana i ka rotor (e like me ka hale squirrel cage i pani ʻia i ka alumini paʻa) e hana i ka mana magnetoelectric rotating torque. Hoʻokaʻawale ʻia nā motika uila iNā motika DCa me nā motika AC e like me ke kumu mana i hoʻohana ʻia. ʻO ka hapa nui o nā kaʻa uila i nā ʻōnaehana mana he mau kaʻa AC, hiki ke hui pū ʻia a i ʻole asynchronous (ʻaʻole mālama ka wikiwiki o ka mīkini stator magnetic field a me ka rotation rotation speed). ʻO kahi kaʻa uila ka nui o kahi stator a me kahi rotor. ʻO ke kuhikuhi o ka neʻe ʻana o kahi uea i hoʻoikaika ʻia i loko o kahi māla magnetic e pili ana i ke kuhikuhi o ka manawa a me ke kuhikuhi o nā laina induction magnetic (alin ʻo ke kahua magnetic). ʻO ke kumu hana o ke kaʻa, ʻo ia ka hana ʻana o ke kahua magnetic ma ke ʻano he ikaika i ke au, e hoʻohuli ai ka motika.

 

三、Ka hana kumu o ke kaʻa uila

 

1. ʻO ke ʻano o kahi motika asynchronous ʻekolu-phase he stator, he rotor a me nā mea ʻē aʻe.

 

2. He octagonal, piha laminated ka hale ka motika DC me ka wili hoʻohiwahiwa series, i kūpono no ka ʻenehana hoʻomalu ʻakomi kahi e koi ʻia ai ka huli ʻana i mua a i hope. Hiki iā lākou ke hana pū me nā wiliwili hoʻohiwahiwa e like me nā koi o ka mea kūʻai aku. ʻO nā kaʻa me ke kiʻekiʻe waena o 100 a 280 mm ʻaʻohe wili uku, akā hiki ke hana ʻia nā motika me ke kiʻekiʻe waena o 250 mm a me 280 mm me ka wili ʻana e like me nā kūlana kikoʻī a me nā pono, a ʻo nā kaʻa me ke kiʻekiʻe waena o 315 a 450 mm he wili uku. ʻO nā ana a me nā koi ʻenehana o nā kaʻa me ke kiʻekiʻe o ke kikowaena o 500-710mm e like me nā kūlana honua IEC, a ʻo ka hoʻomanawanui mechanical dimensional o nā kaʻa e like me nā kūlana honua ISO.

 

 

Aia kekahi ʻokoʻa ma waena o ke kaʻa a me ke kaʻa uila?

 

Loaʻa i nā kaʻa uila nā motika a me nā mea hana. He huaʻōlelo maʻamau ia no nā mea hana a me nā kaʻa, a ʻike ʻia nā mea ʻelua e ka ʻokoʻa. ʻO ke kaʻa uila he hoʻokahi wale nō o nā ʻano hana o ka motika, akā hana ia ma ke ʻano uila, ʻo ia hoʻi ka hoʻololi ʻana o ka ikehu uila i nā ʻano o ka ikehu; ʻO ke ʻano hana ʻē aʻe o ke kaʻa he mīkini hana, e hana ana ma ke ʻano hana mana, e hoʻohuli ana i nā ʻano ikehu ʻē aʻe i ikehu uila. Eia nō naʻe, hoʻohana pinepine ʻia kekahi mau kaʻa e like me nā kaʻa synchronous e like me nā mea hana, akā hiki ke hoʻohana pololei ʻia e like me nā kaʻa uila. Hoʻohana pinepine ʻia nā motika Asynchronous e like me nā kaʻa uila, akā, me ka hoʻohui ʻana o nā ʻāpana peripheral maʻalahi, hiki ke hoʻohana ʻia e like me nā mea hana.
