Hoʻolauna ʻia o ka mīkini DC brushless i nā mea hana mana

Me ka hoʻomaikaʻi ʻana o ka pākaukau hou a me ka ʻenehana kaohi uila, ua hoʻemi nui ʻia ke kumukūʻai hoʻolālā a me ka hana ʻana o ka mīkini DC brushless, a ua hoʻolaha nui ʻia a hoʻohana ʻia nā mea hana rechargeable maʻalahi e pono ai ka mīkini DC brushless. Hoʻohana nui ʻia ia i ka hana ʻoihana, ka ʻākoakoa a me ka mālama ʻana i nā ʻoihana, ʻoiai me ka hoʻomohala waiwai, ke piʻi nei ke koi no ka hale, a ʻoi aku ka kiʻekiʻe o ka ulu makahiki ma mua o nā ʻoihana ʻē aʻe.

2, ʻano noi mīkini hana uila rechargeable kūpono

2.1 Motika DC i palaki ʻia

ʻO ka hoʻolālā ʻana o ka mīkini brushless DC 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.

Kumu hana: Hoʻokomo ʻia ka stator o ka motika DC palaki me kahi pou nui paʻa (magnet) a me ka palaki, a hoʻokomo ʻia ka rotor me ka wili armature a me ka commutator. Komo ka ikehu uila o ka lako mana DC i loko o ka wili armature ma o ka palaki kalapona a me ka commutator, e hana ana i ke au armature. Pili ke kahua magnetic i hana ʻia e ke au armature me ke kahua magnetic nui e hana i ka torque electromagnetic, ka mea e hoʻohuli ai i ka motika a hoʻokele i ka ukana.

Nā Pōʻino: Ma muli o ke ola ʻana o ka pulumu kalapona a me ka commutator, ʻilihune ka hilinaʻi o ka motika pulumu, ka hāʻule ʻana, ka paʻa ʻole o ke au, ke ola pōkole, a e hoʻopuka ka ʻālohilohi o ka commutator i ka hoʻopilikia electromagnetic.

2.2 Motika DC ʻole palaki

ʻO ke ʻano o ka motika DC brushless maʻamau e pili ana i ka rotor motika (ʻau, ʻiʻo hao, magnet, bearing), stator (casing, ʻiʻo hao, winding, sensor, uhi hopena, a me nā mea ʻē aʻe) a me nā ʻāpana hoʻokele.

Kumumanaʻo hana: ʻO ka motika DC Brushless he kino motika a me ka mea hoʻokele, he huahana mechatronics maʻamau. ʻO ke kumumanaʻo hana like ia me ke motika palaki, akā ua pani ʻia ka commutator kuʻuna a me ka palaki kalapona e ka sensor kūlana a me ka laina kaohi, a ua hoʻololi ʻia ke kuhikuhi o ke au e ke kauoha kaohi i hoʻopuka ʻia e ka hōʻailona ʻike e hoʻokō i ka hana commutation, i mea e hōʻoia ai i ka torque electromagnetic mau a me ka hoʻokele o ka motika a hoʻohuli i ka motika.

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

3. Nā pono a me nā hemahema o ka noi ʻana o ka motika BLDC

3.1 Nā Pōmaikaʻi o ka motika BLDC:

3.1.1 ʻAno maʻalahi a me ka maikaʻi hilinaʻi:

Hoʻōki i ka commutator, ka palaki kalapona, ka lima palaki a me nā ʻāpana ʻē aʻe, ʻaʻohe wili commutator, kaʻina hana hoʻopau.

3.1.2 Ola lawelawe lōʻihi:

ʻO ka hoʻohana ʻana i nā ʻāpana uila e hoʻololi i ka hoʻolālā commutator kuʻuna, e hoʻopau i ka motika ma muli o ka pulumu kalapona a me ka commutator commutator spark, ka ʻaʻahu mechanical a me nā pilikia ʻē aʻe i hoʻokumu ʻia e ke ola pōkole, ua hoʻonui ʻia ke ola o ke kaʻa e nā manawa he nui.

3.1.3 Mālie a me ka pono kiʻekiʻe:

ʻAʻohe ʻano palaki kalapona a me ka commutator, e pale i ka ʻālohilohi commutator a me ka friction mechanical ma waena o ka palaki kalapona a me ka commutator, e hopena ana i ka walaʻau, ka wela, ka nalowale o ka ikehu motika, e hōʻemi ana i ka pono o ka motika. ʻO ka pono o ka motika Brushless DC ma 60 ~ 70%, a hiki i ka pono o ka motika brushless DC ke hoʻokō i 75 ~ 90%.

3.1.4 Nā hiki ke hoʻoponopono a me ka hoʻokele wikiwiki ākea:

Hiki i nā ʻāpana uila kikoʻī a me nā sensor ke kaohi pololei i ka wikiwiki o ka hoʻopuka, ka torque a me ke kūlana o ka motika, e ʻike ana i ka naʻauao a me ka multi-functional.
