He aha ke kaʻa?
ʻO ka mīkini uila e pili ana i kahi mea electromagnetic e ʻike ai i ka hoʻololi ʻana o ka ikehu uila a i ʻole ka lawe ʻana e like me ke kānāwai o ka electromagnetic induction.Hōʻike ʻia ke kaʻa e ka leka M (maʻamau D kahiko) i ke kaapuni, a ʻo kāna hana nui ʻo ia ka hana ʻana i ka torque hoʻokele.Ma ke ʻano he kumu mana o nā mea uila a i ʻole nā mīkini like ʻole, ua hōʻike ʻia ka mīkini hana e ka leka G ma ke kaapuni, a ʻo kāna hana nui ka hoʻololi ʻana i ka ikehu uila i ka ikehu mechanical.
1. Rotor 2. ʻO ke kuʻekuʻe o ka lāʻau 3. ʻO ka uhi hope Flanged 4. ʻO ka pahu hui 5. Stator 6. ʻO ke kuʻekuʻe wāwae ʻole 7. Ka uhi hope hope 8. ʻO ka disc brake 9. ʻO ka uhi pā 10. ka peʻahi.
A, mahele kaʻa a me ka hoʻokaʻawale
1. E like me ke ʻano o ka lako mana hana, hiki ke hoʻokaʻawale ʻia i ka motor DC a me ka motor AC.
2. E like me ka hoʻolālā a me ke kumu hana, hiki ke hoʻokaʻawale ʻia i loko o DC motor, asynchronous motor a synchronous motor.
3. E like me ka hoʻomaka 'ana a me ka holo 'ano, hiki ke maheleia i ekolu 'ano: capacitor-hoʻomaka hoʻokahi-phase asynchronous kaʻa, capacitor-holo hoʻokahi-phase asynchronous kaʻa, capacitor-hoʻomaka hoʻokahi-phase asynchronous kaʻa a māhele-phase hoʻokahi- ʻāpana asynchronous motor.
4. E like me ke kumu, hiki ke hoʻokaʻawale ʻia i ka hoʻokele kaʻa a me ka mana hoʻokele.
5. E like me ke ʻano o ka rotor, hiki ke hoʻokaʻawale ʻia i loko o ka squirrel-cage induction motor (ka maʻamau kahiko i kapa ʻia ʻo squirrel-cage asynchronous motor) a me ka ʻeha rotor induction motor (ka maʻamau kahiko i kapa ʻia ʻo wound asynchronous motor).
6. E like me ka holo wikiwiki, hiki ke hoʻokaʻawale ʻia i ke kaʻa kaʻa kiʻekiʻe, ka mīkini haʻahaʻa haʻahaʻa, ke kaʻa kaʻa mau a me ka mīkini hoʻololi.Hoʻokaʻawale ʻia nā kaʻa haʻahaʻa haʻahaʻa i nā mīkini hoʻemi hoʻohaʻahaʻa, nā mīkini hoʻemi electromagnetic, nā kaʻa torque a me nā kaʻa hoʻokaʻawale claw-pole.
ʻO ka lua, he aha ke kaʻa?
ʻO ka motika kekahi ʻano mea hana e hoʻololi i ka ikehu uila i ikehu mechanical.Hoʻohana ia i ka coil electrified (ʻo ia hoʻi, stator winding) e hoʻohua i ke kahua magnetic rotating a hana ma luna o ka rotor (e like me ka squirrel-cage i pani ʻia i ka alumini paʻa) e hana i ka magnetoelectric rotating torque.Hoʻokaʻawale ʻia nā kaʻa i nā motika DC a me nā kaʻa AC e like me nā kumu mana like ʻole.ʻO ka hapa nui o nā kaʻa i loko o ka ʻōnaehana mana he mau kaʻa AC, hiki ke hana i nā motika synchronous a i ʻole nā motors asynchronous (ʻo ka stator magnetic field speed o ke kaʻa ʻaʻole e hoʻomau i ka synchronous me ka wikiwiki o ka rotation).Hoʻokumu nui ʻia ka kaʻa me ka stator a me ka rotor, a ʻo ke kuhikuhi o ka conductor energized i ke kahua magnetic e pili ana i ke kuhikuhi o ka laina induction o kēia manawa a me ka magnetic field direction.ʻO ke kumu hana o ke kaʻa ʻo ia ka hana ʻana o ke kahua magnetic ma ke ʻano o kēia manawa e hoʻohuli ai ke kaʻa.
ʻO ke kolu, ʻo ke ʻano kumu o ka mīkini
1. ʻO ke ʻano o ka motika asynchronous ʻekolu-phase he stator, rotor a me nā mea ʻē aʻe.
2. Ho'ohana ka motor DC i ka octagonal piha laminated structure a me ka series excitation winding, i kūpono no ka 'enehana ho'omalu 'akomi e pono ai i mua a me ka huli 'ana.E like me nā pono o nā mea hoʻohana, hiki ke hana ʻia i kahi wili moʻo.ʻO nā kaʻa me ke kiʻekiʻe waena o 100 ~ 280mm ʻaʻohe wili pānaʻi, akā hiki ke hana ʻia nā kaʻa me ke kiʻekiʻe waena o 250mm 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 ~ 450 mm he wili uku.ʻO nā ʻāpana hoʻonohonoho a me nā koi ʻenehana o ka kaʻa me ke kiʻekiʻe o ke kikowaena o 500 ~ 710 mm e hoʻokō i nā kūlana honua IEC, a ʻo ka ʻae ʻana o ka mīkini e hoʻokō i nā kūlana honua ISO.
Aia kekahi ʻokoʻa ma waena o kahi kaʻa a me kahi kaʻa?
Loaʻa i ka kaʻa kaʻa a me ka mīkini hana.ʻO ka papa papahele o ka mīkini hana a me ka mīkini, ʻokoʻa nā manaʻo ʻelua.ʻO ke kaʻa kaʻa kekahi o nā ʻano hana kaʻa kaʻa, akā ke hana nei ke kaʻa ma ke ʻano uila, ʻo ia hoʻi, hoʻololi ia i ka ikehu uila i nā ʻano o ka ikehu;ʻO ke ʻano hana ʻē aʻe o ke kaʻa ʻo ka generator.I kēia manawa, hana ia i ke ʻano hana mana a hoʻololi i nā ʻano ʻano o ka ikehu i ka ikehu uila.Eia nō naʻe, hoʻohana mau ʻia kekahi mau kaʻa, e like me nā motika synchronous, e like me nā mea hana, akā hiki ke hoʻohana pololei ʻia e like me nā kaʻa.ʻOi aku ka hoʻohana ʻana o nā motika Asynchronous no nā kaʻa, akā hiki ke hoʻohana ʻia e like me nā mea hana ma ka hoʻohui ʻana i nā ʻāpana peripheral maʻalahi.
