Hiki i nā mea hoʻokalakupua honua laminated ke hōʻemi i nā poho eddy i kēia manawa i nā kaʻa kaʻa kiʻekiʻe.ʻO nā poho liʻiliʻi eddy i kēia manawa ʻo ia ka wela haʻahaʻa a ʻoi aku ka maikaʻi.
I loko o nā kaʻa kaʻa hoʻohui mau, ʻaʻole mālama ʻia nā poho o kēia manawa i loko o ka rotor no ka mea ke kaʻa like nei ka rotor a me ka stator.ʻO ka ʻoiaʻiʻo, ʻo nā hopena stator slot, ka hāʻawi ʻole-sinusoidal o nā mana magnetic wiliwili a me nā mana magnetic harmonic i hoʻokumu ʻia e nā au harmonic i ka wili wili pū kekahi ke kumu o nā poho eddy i loko o ka rotor, ʻauamo rotor a me nā metala mau loa e hoʻopaʻa ana i ka sheath magnet mau loa.
No ka mea, ʻo 220 ° C (N35AH) ka mahana hana kiʻekiʻe loa o nā magnet NdFeB sintered, ʻoi aku ka kiʻekiʻe o ka mahana hana, ʻoi aku ka haʻahaʻa o ka magnetism o nā magnet NdFeB.Kapa ʻia kēia i ka wela!Hiki i kēia mau poho eddy ke alakaʻi i nā wela kiʻekiʻe, e alakaʻi ana i ka demagnetization kūloko o nā magnet mau loa, ʻo ia ka mea koʻikoʻi i kekahi mau kiʻekiʻe kiʻekiʻe a i ʻole kiʻekiʻe kiʻekiʻe mau loa magnet synchronous motor.
ʻO ka poho wela ke kumu nui ʻia e ka electromagnetic eddy current i ka wā o ka hana kaʻa.No laila, he nui nā ʻano hoʻopaʻa ʻana (e koi ana i ka insulation ma waena o kēlā me kēia magnet) e hōʻemi i kēia nalowale wela.
1. Ka thinnest insulation, <20 microns;
2. Hana ma nā mahana a hiki i 220˚C;
3. ʻO nā papa Magnet mai 0.5 mm a ma luna aʻe he ʻano maʻamau a me ka nui neodymium magnets.
HKe huli nei nā ʻenekini magnet permanent igh-speed, aerospace, automotive, motorsport a me nā mākeke ʻoihana i nā laminated rare earth magnets a ke hana nei lākou e kaulike i ke kālepa ma waena o ka mana a me ka wela.
Anā pono: hiki iā ia ke hōʻemi i ka nalowale o ka ikehu i hana ʻia e ka electromagnetic eddy current.
