ʻO kahi loiloi pōkole o nā ʻano a me nā ʻokoʻa ma waena o BLDC a me PMSM.

I ke ola o kēlā me kēia lā, mai nā mea pāʻani uila a i nā kaʻa uila,uila hiki ke ʻōlelo ʻia nā motika ma nā wahi āpau. Hele mai kēia mau kaʻa i nā ʻano like ʻole e like me nā motika DC brushed, nā motika DC brushless (BLDC), a me nā motika synchronous magnet mau loa (PMSM). Loaʻa i kēlā me kēia ʻano kona mau hiʻohiʻona a me nā ʻokoʻa, e kūpono iā lākou no nā noi like ʻole.

E hoʻomaka kākou me nā motika DC brushed. Ua puni kēia mau kaʻa no ka manawa lōʻihi a hoʻohana nui ʻia i nā noi kahi mea koʻikoʻi ka maʻalahi a me ke kumukūʻai. Hoʻohana nā motika DC i hoʻohana ʻia i nā pulupulu a me kahi commutator e hāʻawi i ka mana i ka rotor o ka moto. Eia nō naʻe, ua pau kēia mau pulupulu i ka wā lōʻihi, e hoʻemi ana i ka pono a me ka hilinaʻi. Hoʻohui ʻia, hoʻopuka nā motika DC brushed i ka leo uila ma muli o ka hoʻopili mau ʻana o nā brushes me ka commutator, e kaupalena ana i kā lākou hoʻohana ʻana i kekahi mau noi.

Ma ka ʻaoʻao ʻē aʻe, ʻo nā kaʻa BLDC, e like me ka manaʻo o ka inoa, mai hoʻohana i nā pulupulu no ka commutation. Akā, hoʻohana lākou i nā mea hoʻololi i hoʻopaʻa ʻia e ka uila e hoʻomalu i nā au o ke kaʻa. Hāʻawi kēia hoʻolālā brushless i nā pono he nui ma mua o nā motika DC brushed. ʻO ka mea mua, ʻoi aku ka hilinaʻi o nā kaʻa BLDC a ʻoi aku ka maikaʻi o ka maikaʻi no ka mea ʻaʻohe polu e pau. ʻO kēia hoʻomaikaʻi ʻana i ka pono e unuhi ʻia i loko o ka mālama ʻana i ka ikehu a me ka hoʻonui ʻana i ke ola pākaukau ma nā polokalamu kelepona. Eia kekahi, ʻo ka loaʻa ʻole o nā pulupulu e hoʻopau i ka leo uila, e ʻae ai i ka hana mālie, e hoʻolilo i nā motika BLDC i kūpono no nā noi kahi mea koʻikoʻi ka walaʻau, e like me nā kaʻa uila a me nā drones.

I ka hiki ʻana i ka PMSM, kaʻana like lākou me nā kaʻa BLDC akā loaʻa nā ʻokoʻa liʻiliʻi i kā lākou kūkulu ʻana a me ka mana. ʻO nā kaʻa PMSM pū kekahiE hoʻohana i nā magnet mau loa i ka rotor, e like me nā motika BLDC. Eia naʻe, Loaʻa i nā kaʻa PMSM kahi nalu sinusoidal back-EMF, aʻo nā motika BLDC he hawewe trapezoidal. Hoʻopili kēia ʻokoʻa i ka nalu i ka hoʻolālā hoʻokele a me ka hana o nā kaʻa.

Hāʻawi nā kaʻa PMSM i nā pono ma mua o nā kaʻa BLDC. ʻO ka sinusoidal back-EMF waveform e hana maʻalahi i ka torque a me ka hana, e hoʻemi ana i ka cogging a me ka haʻalulu. He mea kūpono kēia i nā kaʻa PMSM no nā noi e koi ana i ka pololei kiʻekiʻe a me ka hana maʻalahi, e like me nā robotics a me nā mīkini ʻenehana. Eia kekahi, ʻoi aku ka nui o ka mana o ka PMSM, ʻo ia hoʻi, hiki iā lākou ke hāʻawi i ka mana hou aʻe no ka nui kaʻa i hāʻawi ʻia i hoʻohālikelike ʻia me nā motika BLDC.

Ma ke ʻano o ka mana, hoʻokele mau ʻia nā motika BLDC me ka hoʻohana ʻana i kahi hoʻolālā commutation ʻeono-ʻanuʻu, aʻo nā kaʻa PMSM e koi aku i nā algorithms mana paʻakikī a paʻakikī. Pono nā kaʻa PMSM i ke kūlana a me ka wikiwiki no ka mana pololei. Hoʻohui kēia i ka paʻakikī a me ke kumukūʻai i ka ʻōnaehana hoʻokele kaʻa akā hiki i ka wikiwiki a me ka mana torque maikaʻi, kūpono no nā noi e koi ana i ka hana kiʻekiʻe a me ka pololei.

ʻO Anhui Mingteng Electr Magnet Paʻaical&mekini Equipment Co., Ltd. he ʻoihana ʻenehana kiʻekiʻe hou e hoʻohui i ka noiʻi a me ka hoʻomohala ʻana, ka hana ʻana, ke kūʻai aku, a me ka lawelawe ʻana o nā kaʻa kaʻa magnet mau loa. Loaʻa iā mākou kahi hui noiʻi ʻoihana a me ka hoʻomohala ʻana ma luna o 40 mau mīkini magnet paʻa, hoʻomaopopo piha i nā koi ʻenehana o nā mea hoʻokele like ʻole i nā ʻoihana like ʻole. Ua holo pono ka hui o ka hui ma na haawe he nui e like me ka pehi, ka pauma wai, ka mea lawe kaei, wili poepoe, mixers, crushers, scraper machines, and oil extraction machines in different fields like cement, mining, steel, and electricity. ka loaʻa ʻana o nā hopena hoʻopakele ikehu maikaʻi a loaʻa ka mahalo ākea. Ke kakali nei mākou i nā Minten hou aʻeg Hoʻohana ʻia nā mīkini PM i nā kūlana hana like ʻole e mālama i ka ikehu a hōʻemi i ka hoʻohana ʻana no nā ʻoihana!
