No ka aerospace, automotive, a i ʻole ʻenehana ʻoihana, he mea nui ka pono o nā kaʻa kaʻa kiʻekiʻe. Eia naʻe, ʻo ka wikiwiki kiʻekiʻe ka hopena mau i ka kiʻekiʻeeddy aua laila e hopena i ka nalowale o ka ikehu a me ka wela, e hoʻopilikia i ka hana kaʻa i ka manawa.
ʻo ia ke kumumākēneki kūʻē i kēia manawasua lilo i mea nui. Kōkua kēia mau mea magnet i ka hoʻomalu ʻana i nā au eddy, mālama i ka wela a me ka holo ʻoi aku ka maikaʻi o nā kaʻa - ʻoi aku ka nui o nā kaʻa hoʻokele magnetic a me nā kaʻa hoʻokele ea. Ma kēia ʻatikala, e wehewehe mākou i ka hana ʻana o kēia ʻenehana a me ke kumu o nā huahana o“Mana Mākēneki”ua kūpono loa, mahalo i ko lākou resistivity kiʻekiʻe a me ka hana haʻahaʻa wela.
1. Ka Eddy Currents
Ua hoʻokomo ʻia nā kahawai Eddy e "Mana Mākēneki”ma ka nūhou mua).
I nā kaʻa kaʻa kiʻekiʻe, e like me nā mea i hoʻohana ʻia i ka aerospace a i ʻole nā compressors (Line speed ≥ 200m/s), hiki i nā au eddy ke lilo i pilikia nui. Hoʻokumu lākou i loko o nā rotors a me nā stators i ka loli wikiwiki ʻana o ke kahua magnetic.
ʻAʻole he pilikia liʻiliʻi wale nō ka eddy au; hiki iā lākou ke hōʻemi i ka pono kaʻa a hiki ke hōʻeha i ka wā. Hōʻike ʻia kēia:
- Wela Nui: Hoʻoulu ʻia ka wela o Eddy, kahi e hoʻonui ai i ke koʻikoʻi ma nā ʻāpana kaʻa. No ka laʻana, ʻo ka lilo ʻole o ka magnetic mau loa o NdFeB a i ʻole SmCo hiki mau ma muli o ka wela kiʻekiʻe.
- Pohō i ka ikehu: ua emi ka pono o ke kaa no ka mea, ua pau ka ikehu e hiki ai ke hoohana i ke kaa i ka hana ana i keia mau au eddy.
2. Pehea e kōkua ai nā mea hoʻoheheʻe Anti-Eddy Current
Mākēneki anti-eddyua hoʻolālā ʻia e hoʻoponopono i kēia pilikia. Ma ka hoʻopaʻa ʻana i ke ʻano a me kahi e puka mai ai nā au eddy, hōʻoia lākou i ka holo pono ʻana o ka kaʻa a noho mālie. ʻO kahi ala maikaʻi e ālai ai i nā au eddy ʻo ka hana ʻana i nā magnets i ka hoʻolālā lamination. Hiki i kēia ʻano hana ke uhaki i ke ala eddy o kēia manawa, a laila pale i ka hoʻokumu ʻana o nā au nui.
3. No ke aha i kūpono ai nā hui o MagnetPower Tech no nā kaʻa holo kiʻekiʻe
I kēia manawa, e luʻu kākou i nā pono kūikawā oʻO MagnetPower 'snā hui anti-eddy o kēia manawa. He kūpono kēia mau hui no nā kaʻa kaʻa kaʻa a me nā kaʻa lawe lewa, e hāʻawi ana i kahi hui o ka resistivity kiʻekiʻe, ka hana haʻahaʻa wela, a me ka hoʻonui ʻana i ke ola kaʻa.
3.1 Kū'ē kiʻekiʻe = ʻOi aku ka maikaʻi
ʻO nā mākēneki anti-eddy o kēia manawa i hoʻomohala ʻia e "Magnet Power" e hoʻohana i ka insulating glue ma waena o nā ʻāpana o nā mea hoʻokaʻawale, hoʻonui lākou i ka pale uila, ma luna o 2MΩ·cm. He mea maikaʻi ke uhaki i ke ala eddy o kēia manawa. No laila, ʻaʻole maʻalahi ka wela. He mea koʻikoʻi kēia i nā kaʻa hoʻokele magnetic. Ma ka hōʻemi ʻana i ka wela, hōʻoia nā mea hoʻokalakupua o MagnetPower i ka holo mālie ʻana o nā kaʻa i nā wikiwiki kiʻekiʻe me ka pilikia ʻole o ka wela. Ua like nonā motika ea-ʻO ka wela haʻahaʻa e mālama i ka ea ma waena o ka rotor a me ka stator stable, ʻo ia ke kī nui no ka pololei.
Fig1 nā mākēneki anti-eddy i hana ʻia e Magnet Power
3.2 Kiʻekiʻe magnetic flux
Hana ʻia nā magnet me ka mānoanoa o 1mm a loaʻa kahi ʻāpana insulation lahilahi o 0.03mm. Mālama kēia i ka leo o ke kāpili liʻiliʻi a ʻoi aku ka nui o ka nui o nā magnet.
3.3 kumu kūʻai haʻahaʻa
ʻO kēia kaʻina hana hoʻohaʻahaʻa i nā koi coercivity a me nā kumukūʻai i ka hoʻonui ʻana i ka paʻa wela, ʻoi loa no nā magnet NdFeB. Inā hiki ke hoʻemi ʻia ka mahana o ka rotor mai 180 ℃ a 100 ℃, hiki ke hoʻololi ʻia ka papa o nā magnet mai EH a SH. ʻO kēia ke ʻano o ke kumukūʻai o nā magnet hiki ke hoʻemi ʻia e ka hapalua.
4. Pehea ka hana ana o ka MagnetPower i na Motors Kiekie
E nana kakou i ke ano o ka MagnetPower's anti-eddy current magnets in magnetic bearing motors and ea bearing motors.
4.1 Mākēneki Lawe Motors: Paʻa ma High Speed
I nā kaʻa kaʻa kaʻa magnetic, hoʻopaʻa ʻia ka mea hoʻokele i ka rotor, e ʻae iā ia e hoʻololi me ka ʻole o ka hoʻopā ʻana i nā ʻāpana ʻē aʻe. Akā ma muli o ka mana kiʻekiʻe (ma mua o 200kW) a me ka wikiwiki kiʻekiʻe (ma mua o 150m/s, a i ʻole ma luna o 25000RPM), ʻaʻole maʻalahi ka hoʻokele eddy current. Hōʻike ka Fig.2 i kahi rotor me ka wikiwiki o 30000RPM. Ma muli o ka nui o ka eddy i kēia manawa, ua hana ʻia ka wela nui, e ʻike ai ka rotor i kahi wela kiʻekiʻe ma mua o 500°C.
Kōkua nā mea hoʻokalakupua o MagnetPower i ka pale ʻana i kēia ma ka hōʻemi ʻana i ka hoʻokumu ʻana i kēia manawa eddy. ʻAʻole i ʻoi aku ka mahana o ka rotor i hoʻomaikaʻi ʻia ma mua o 200 ℃ ma ke kūlana hana like.3
Fig.2 he rotor ma hope o ka ho'āʻo me ka wikiwiki o 30000RPM.
4.2 Nā ʻenekini lawe lewa: pololei i ka wikiwiki kiʻekiʻe
Ke hoʻohana nei nā ʻenekini lawe lewa i kahi kiʻiʻoniʻoni ʻoniʻoni o ka ea e hana ʻia e ka wikiwiki wikiwiki e kākoʻo i ka rotor. Hoʻolālā ʻia kēia mau kaʻa e hana i nā wikiwiki kiʻekiʻe loa, a hiki i 200,000RPM, me ka pololei kupaianaha. Eia nō naʻe, hiki i nā au eddy ke hoʻopilikia i kēlā kikoʻī ma o ka hoʻoulu ʻana i ka wela keu a me ka hoʻopili ʻana i ke āpau o ka ea.
Me nā mākēneki o MagnetPower, ua hoʻemi ʻia nā au eddy, ʻo ia hoʻi, e noho mālie ke kaʻa a mālama pono i ka ea ākea e pono ai no nā noi kiʻekiʻe e like me Hydrogen fuel cell compressor and blower.
Ka hopena
I ka hiki ʻana i nā kaʻa kaʻa kiʻekiʻe, ʻo ka hōʻemi ʻana i ka nalowale o ka ikehu a me ka hoʻomalu ʻana i ka hana wela ke kī i ka hoʻomaikaʻi ʻana i ka hana a hoʻonui i ke ola o kāu mau mea hana. ʻO ia kahi i komo mai ai nā magnets anti-eddy o kēia manawa o MagnetPower.
Mahalo i ka hoʻohana ʻana i nā mea kiʻekiʻe-resistivity, nā hoʻolālā akamai e like me ka māhele a me ka lamination, a me ka nānā ʻana i ka hōʻemi ʻana i nā au eddy, kōkua kēia mau hui i nā kaʻa e holo mālie, ʻoi aku ka maikaʻi, a no ka lōʻihi. Inā i loko o nā kaʻa kaʻa kaʻa, nā kaʻa lawe ea, a i ʻole nā noi kiʻekiʻe ʻē aʻe, ʻo MagnetPower ke koi nei i nā palena o nā mea e hiki ai i ka pono a me ka hilinaʻi.
