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 motika 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 sima, mining, kila, a me ka uila. 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!
