No ke aha e mālama ʻia ai ka ikehu o nā motika magnet mau?

I nā makahiki i hala iho nei, ʻo ka ʻoihana kaʻa i ka wā o ke kiʻekiʻe kiʻekiʻe o nā mīkini magnet mau loa, ke kiʻekiʻe o ka kaulana e hōʻike ana i kahi ulu ulu. Wahi a ka nānā ʻana, ʻo ke kumu e hopohopo pālua ai nā kaʻa magnet paʻa, ʻaʻole hiki ke hoʻokaʻawale ʻia mai ke kākoʻo ikaika ʻana o nā kulekele mokuʻāina e pili ana i nā mīkini paʻa paʻa kiʻekiʻe ma ke ʻano he mākaʻikaʻi o nā huahana kiʻekiʻe, ultra-high-efficiency. hoʻolaha ʻia e kōkua i ka mālama ʻana i ka ikehu a me ka hoʻemi ʻana i ka hoʻokuʻu ʻana, e mālama i nā mauna ʻōmaʻomaʻo a me ka wai ʻōmaʻomaʻo. ʻO ka mālama ʻana i ka ikehu a me ka mālama ʻana i ke kaiapuni pono ke ʻano o ka hoʻomohala ʻana i ka wā e hiki mai ana, ʻoi aku hoʻi i ka ʻoihana kaʻa, nā hiʻohiʻona hoʻōla ʻana i ka ikehu mau loa e hōʻike ana i kona mau pōmaikaʻi ma waho o ka nui o ka mālama ʻana i ka ikehu hiki ke kiʻekiʻe ma mua o 20%, ma ka honua laʻa. -ʻo nā pōmaikaʻi mālama mālama penei:

ʻEono mau pono hoʻopakele ikehu

1, ʻoi aku ka mīkini paʻa paʻa ma mua o ka mālama ʻana i ka ikehu kaʻa maʻamau 5% -30%, ʻokoʻa nā ʻano hana hana o nā ʻano hoʻōla mana like ʻole.

2, mau mīkini paʻa synchronous e hoʻokō i kahi kiʻekiʻe o ka ikaika o ka ikehu, ka ikaika o ka ikehu ma mua o 95%; ʻO ka mīkini asynchronous ʻekolu-phase maʻamau ʻekolu mau ikehu, ʻoi aku ka maikaʻi o ka ikehu ma kahi o 90%.

3, loaʻa i ke kila magnet permanent magnet synchronous motor rotor, ʻaʻole pono ka stator e hāʻawi i ka mana induction, ʻoi aku ka liʻiliʻi o ka poho kaʻa maʻamau;

4, mau magnet synchronous motor stator alakaʻi uea he hōkū (Y) pili, hiki ke mālama i ka mana i hoʻololi ʻole ʻia ka liʻiliʻi; ʻO nā kaʻa maʻamau ka hapa nui o △ pili;

5, ka mīkini paʻa paʻa synchronous i ke kaʻina hana, i ka wā e loli ai ka ukana i ka wā e hiki ai ke hoʻololi ʻole ka waiwai o ka ikehu, ka mīkini asynchronous maʻamau i ka wā e hoʻololi ai ka ukana i ka wā e loli ai ka waiwai o ka ikehu, ka mīkini asynchronous maʻamau i ka ukana a hiki i ʻekolu hapaha. ʻAʻole i hoʻololi ʻia ka waiwai o ka ikehu, ke emi iho ka ukana ma mua o 70% o ka waiwai o kona ikehu e hāʻule pololei i lalo.

6, paʻa magnet synchronous kaʻa kaʻa no-haawe i kēia manawa he uuku, hoʻokahi hapaʻumi wale nō o ka helu o kēia manawa, aʻo ka maʻamau asynchronous kaʻa i loko o ka no-haawe o kēia manawa a hiki i ka hapakolu.

ʻEkolu mau ʻāpana nui ʻekolu mau mea nui

1、Hoʻohana ʻo Rare earth permanent magnet motor kiʻekiʻe-performance mau loa, kahi e hoʻopau ai i ka excitation o kēia manawa o ka stator a i ʻole ka ʻāpana rotor o ke kaʻa, no laila e hoʻopau i ka nalowale keleawe o kēia ʻāpana (weli wela wela);

2, ʻo ka hoʻohana ʻana i ka hana brushless, ʻaʻohe kalapona kalapona o ka poho mechanical, akā ʻo ka mīkini brushless ma o ka ʻōnaehana commutation uila e ʻike ai i ka commutation, eia kahi ʻāpana o nā ʻāpana uila o ka poho, a mālama i ka poho mechanical i hoʻohālikelike ʻia. liʻiliʻi ka waiwai pohō, no laila he liʻiliʻi ka ʻāpana hoʻololi o ka pohō ma mua o ka nalowale o ka poho kaʻa brush;

3, ka hoʻohana ʻana i nā mea hoʻokalakupua mau loa o ka honua, i ka mana helu like a me ka wikiwiki i helu ʻia, hiki ke hoʻemi ʻia ka leo kaʻa, e hoʻopakele ana i ka ʻāpana kila silikona, e hōʻemi ana i kahi hapa o ka hao. Hiki i nā kaʻa mana liʻiliʻi e hoʻohana ana i ka mīkini paʻa mau loa e hiki ke kokoke i ka 90% pono, ʻo ka mīkini maʻamau ma kahi o 75%.

Ua lilo ka hoʻohana ʻana i ka PMSM i mea maʻamau no nā ʻoihana e mālama i ka ikehu, hoʻemi i ka hoʻokuʻu ʻana, a hoʻokō i ka hoʻomohala ʻōmaʻomaʻo win-win.
