He aha nā mea i hoʻohana ʻia no nā laminations i ka stator a me ka rotor o kahi kaʻa?

ʻO karotoro ka mokini DC he apana kila uila. Ke hoʻololi ka rotor i ke kahua mākēneki o ka kaʻa, hoʻopuka ia i ka volta i loko o ka coil, kahi e hoʻoulu ai i nā au eddy, ʻo ia ke ʻano o ka nalo magnetic, a ʻo ka nalowale o kēia manawa e alakaʻi i ka nalowale o ka mana. Hoʻopili kekahi mau mea i ka hopena o nā au eddy i ka nalo o ka mana, e like me ke kahua electromagnetic, ka mānoanoa o ka mea magnetic, a me ka nui o ka flux magnetic. ʻO ke kūʻē ʻana o ka mea i ke au e pili ana i ke ʻano o ka hana ʻana o nā au eddy, no ka laʻana, ke mānoanoa loa ka mea, piʻi ka ʻāpana cross-sectional, e hopena i nā poho o kēia manawa. Pono nā mea ʻoi aku ka lahilahi e hōʻemi i ka ʻāpana ʻāpana. No ka ʻoi aku ka lahilahi o ka mea, hoʻohana nā mea hana i nā ʻāpana lahilahi i kapa ʻia he laminations e hana ai i ke kumu armature, a ʻaʻole e like me nā ʻāpana mānoanoa, ʻoi aku ka ikaika o nā lau ʻoi aku ka nui o ke kūʻē ʻana, e hopena i ka emi ʻana o ka eddy.

ʻO ke koho ʻana i nā mea i hoʻohana ʻia no ka laminations kaʻa kekahi o nā mea nui e noʻonoʻo ai i ke kaʻina hana hoʻolālā kaʻa, a ma muli o kā lākou versatility, ʻo kekahi o nā koho kaulana loa ʻo ia ke kila kila a me ke kila silika. ʻO nā mea kila kila kiʻekiʻe (2-5.5 wt% silicon) a me ka pā lahilahi (0.2-0.65 mm) nā mea kila palupalu no nā stators a me nā rotors. ʻO ka hoʻohui ʻana o ke silikoni i ka hao ka hopena o ka coercivity haʻahaʻa a me ka resistivity kiʻekiʻe, a ʻo ka hoʻemi ʻana i ka mānoanoa pā lahilahi e hopena i nā poho o kēia manawa.
ʻO ke kila laminated cold rolled kekahi o nā kumu kūʻai haʻahaʻa loa i ka hana nui a ʻo ia kekahi o nā mea hoʻohui kaulana loa. He mea maʻalahi ka hoʻopaʻa ʻana a hoʻemi ʻia ka ʻaʻahu ma luna o ka mea hana stamping ma mua o nā mea ʻē aʻe. Hoʻopili nā mea hana kaʻa i ke kila laminated kaʻa me kahi kiʻiʻoniʻoni oxide e hoʻonui ai i ke kūpaʻa interlayer, e hoʻohālikelike ʻia me nā kila-silikona haʻahaʻa. ʻO ka ʻokoʻa ma waena o ke kila laminated kaʻa a me ke kila i ʻōwili ʻia i loko o ke kila kila a me ka hoʻoponopono ʻana (e like me ka annealing).
ʻO ke kila silikoni, ʻike ʻia hoʻi ʻo ke kila uila, he kila kalapona haʻahaʻa me kahi mea liʻiliʻi o ke silikona i hoʻohui ʻia e hōʻemi i nā poho eddy i kēia manawa i loko o ke kumu. Mālama ʻo Silicon i ka stator a me nā cores transformer a hōʻemi i ka hysteresis o ka mea, ka manawa ma waena o ka hanauna mua o ka māla magnetic a me kona hanauna piha. I ka wā i ʻōwili ʻia ai ke anu a hoʻonohonoho pono ʻia, ua mākaukau ka mea no nā noi lamination. ʻO ka maʻamau, ua hoʻokaʻawale ʻia nā laminates kila silika ma nā ʻaoʻao ʻelua a hoʻopaʻa ʻia ma luna o kekahi i mea e hōʻemi ai i nā au eddy, a ʻo ka hoʻohui ʻana o ke silika i ka huila he hopena koʻikoʻi i ke ola o nā mea hana stamping a make.
Loaʻa ke kila silikoni i nā mānoanoa like ʻole a me nā māka, me ke ʻano maikaʻi loa e pili ana i ka poho hao i ʻae ʻia i nā watts no ka kilo. Hoʻopili kēlā me kēia papa a me ka mānoanoa i ka insulation o ka ʻili, ke ola o ka mea hana stamping, a me ke ola o ka make. E like me ke kila laminated kaʻa anu, kōkua ka annealing i ka hoʻoikaika ʻana i ke kila silika, a ʻo ke kaʻina hana annealing post-stamping e hoʻopau i ke kalapona keu, a laila e hōʻemi i ke kaumaha. Ma muli o ke ʻano o ke kila silika i hoʻohana ʻia, pono ka mālama hou ʻana i ka ʻāpana e hoʻomaha hou i ke kaumaha.
ʻO ke kaʻina hana kila i hoʻohui ʻia i nā mea maikaʻi loa i ka mea maka. Hana ʻia ka hana ʻala anu ma luna a i ʻole ma luna o ka wela o ka lumi, e hopena i nā hua kila i koe e elongated i ka ʻaoʻao ʻōwili. ʻO ke kaomi kiʻekiʻe i hoʻopili ʻia i ka mea i ka wā o ka hana ʻana e mālama i nā koi rigidity inherent o ke kila anuanu, e hopena i kahi ʻili laulima a ʻoi aku ka pololei a me nā ana kūlike. ʻO ke kaʻina ʻōwili anuanu ke kumu i kapa ʻia ʻo "strain hardening", hiki ke hoʻonui i ka paʻakikī a hiki i ka 20% ke hoʻohālikelike ʻia me ke kila ʻaʻole i ʻōwili ʻia ma nā māka i kapa ʻia ʻo piha paʻakikī, semi-paʻakikī, ʻehā paʻa a me ka ʻili ʻili. Loaʻa ka Rolling i nā ʻano like ʻole, e like me ka poepoe, square a me ka pālahalaha, a ma nā ʻano helu like ʻole e kūpono i ka nui o ka ikaika, ka ikaika a me nā koi ductility, a ke hoʻomau nei kāna kumu kūʻai haʻahaʻa e lilo i iwi kuamoʻo o nā hana laminated āpau.
ʻO karotorastatori loko o kahi kaʻa i hana ʻia mai nā haneli o nā laminated a hui pū ʻia me nā ʻāpana kila uila, e hōʻemi ana i nā poho eddy o kēia manawa a hoʻonui i ka pono, a ua uhi ʻia ʻelua me ka insulation ma nā ʻaoʻao ʻelua e laminate i ke kila a ʻoki ʻia nā au eddy ma waena o nā papa o ka noi kaʻa. . ʻO ka maʻamau, ua hoʻopaʻa ʻia ke kila uila e hōʻoia i ka ikaika mechanical o ka laminate. ʻO ka pōʻino i ka uhi insulation mai ke kaʻina hana kuʻi ʻana hiki ke alakaʻi i ka emi ʻana o nā waiwai magnetic, nā loli i ka microstructure, a me ka hoʻokomo ʻana i nā koena koʻikoʻi, e lilo ia i mea paʻakikī nui e hoʻololi i waena o ka ikaika mechanical a me nā waiwai magnetic.
