ʻO ka hoʻolauna ʻana i ka mīkini DC brushless i nā mea hana mana

Me ka hoʻomaikaʻi ʻana o ka pākaukau hou a me ka ʻenehana hoʻokele uila, ua hoʻemi nui ʻia ka hoʻolālā ʻana a me ke kumukūʻai o ka mīkini DC brushless, a ua hoʻolaha nui ʻia a hoʻohana nui ʻia nā mea hana hoʻihoʻi hou e koi ana i ka mīkini DC brushless. Hoʻohana nui ʻia ia i nā ʻoihana ʻenehana, hui a me nā ʻoihana mālama, ʻoi aku hoʻi me ka hoʻomohala ʻana i ka hoʻokele waiwai, ke piʻi aʻe nei ke koi no ka home, a ʻoi aku ka kiʻekiʻe o ka ulu makahiki ma mua o nā ʻoihana ʻē aʻe.

2, maʻalahi rechargeable uila mea paahana kaʻaʻano palapala noi

2.1 ʻO ka motika DC i palaki ʻia

ʻO ka hoʻolālā kaʻa DC brushless maʻamau e pili ana i ka rotor (shaft, iron core, winding, commutator, bearing), stator (casing, magnet, end cap, etc.), carbon brush assembly, carbon brush arm a me nā ʻāpana ʻē aʻe.

ʻO ke kumu hana: Hoʻokomo ʻia ka stator o ka mīkini DC brushed me kahi pou nui paʻa (magnet) a me ka pulupulu, a hoʻokomo ʻia ka rotor me ka wili armature a me ka commutator. ʻO ka ikehu uila o ka mana DC e komo i ka armature winding ma o ke kalapona kalapona a me ka commutator, e hoʻopuka ana i ka manawa armature. Hoʻopili ke kahua magnetic i hana ʻia e ka armature me ke kahua magnetic nui e hoʻohua ai i ka torque electromagnetic, kahi e hoʻohuli ai ke kaʻa a hoʻokele i ka ukana.

Nā pōʻino: Ma muli o ke ola ʻana o ka pulupulu kalapona a me ka commutator, maikaʻi ʻole ka hilinaʻi ʻana o ka kaʻa kaʻa, ka hiki ʻole, ka paʻa ʻole o kēia manawa, ke ola pōkole, a me ka commutator spark e hoʻopuka i ka interference electromagnetic.

2.2 Brushless DC motor

ʻO ke ʻano kaʻa kaʻa DC brushless maʻamau e pili ana i ka rotor kaʻa (shaft, iron core, magnet, bearing), stator (casing, iron core, winding, sensor, end cover, etc.) a me nā mea hoʻokele.

ʻO ke kumu hana: ʻO ke kaʻa Brushless DC ke kino kaʻa a me ka mea hoʻokele, he huahana mechatronics maʻamau. ʻO ka loina hana e like me ka mīkini palaki, akā ua hoʻololi ʻia ka commutator kuʻuna a me ke kalapona e ka sensor kūlana a me ka laina mana, a ua hoʻohuli ʻia ke kuhikuhi o kēia manawa e ke kauoha mana i hoʻopuka ʻia e ka ʻike ʻana i ka hōʻailona e ʻike ai i ka hana commutation, no laila. e hōʻoia i ka hoʻokele electromagnetic mau a me ka hoʻokele ʻana o ke kaʻa a hoʻololi i ka ʻenekini.

Ka nānā ʻana o ka mīkini DC brushless i nā mea hana mana

3. Nā pōmaikaʻi a me nā pōʻino o ka noi kaʻa BLDC

3.1 Pono o ka motika BLDC:

3.1.1 Hana maʻalahi a me ka maikaʻi hilinaʻi:

Hoʻopau i ka commutator, carbon brush, brush arm a me nā ʻāpana ʻē aʻe, ʻaʻohe commutator welding, hoʻopau kaʻina.

3.1.2 Ola lōʻihi:

ʻO ka hoʻohana ʻana i nā ʻāpana uila e hoʻololi i ka ʻōnaehana commutator kuʻuna, hoʻopau i ke kaʻa ma muli o ke kalapona kalapona a me ka commutator commutator spark, ka lole mechanical a me nā pilikia ʻē aʻe i hoʻokumu ʻia e ke ola pōkole, hoʻonui ʻia ke ola kaʻa e ka lehulehu.

3.1.3 Noho mālie a kiʻekiʻe ka maikaʻi:

ʻAʻohe kalapona kalapona a me ka commutator structure, e pale aku i ka commutator spark a me ka mechanical friction ma waena o carbon brush and commutator, ka hopena i ka walaʻau, ka wela, ka nalowale o ka ikehu kaʻa, hoʻemi i ka pono o ka kaʻa. Brushless DC kaʻa kaʻa ka pono ma 60 ~ 70%, a brushless DC kaʻa kaʻa hiki ke hoʻokō 75 ~ 90%

3.1.4 ʻOi aku ka nui o ka hoʻoponopono ʻana i ka wikiwiki a me ka mana hoʻomalu:

Hiki i nā ʻāpana uila pololei a me nā mea ʻike ke hoʻomalu pono i ka wikiwiki o ka puka, torque a me ke kūlana o ka kaʻa, ʻike i ka naʻauao a me nā hana he nui.
