He aha ka ʻokoʻa ma waena o ka mīkini palaki a me ka pahi ʻole?

Hoʻokahi kumu kumu o ka hoʻololi ʻana i ke au uila i ka neʻe ʻana o ka uila.

Ua puni nā motika brushed no hoʻokahi haneli, ʻoiai ua puka mai nā kaʻa brushless i nā makahiki 1960 me ka hoʻomohala ʻana i nā mea uila paʻa i hiki ai i kā lākou hoʻolālā.Eia naʻe, ʻaʻole i hiki i ka makahiki 1980 ka hoʻomaka ʻana o nā mīkini brushless e loaʻa i ka ʻae ākea i nā mea hana like ʻole a me nā mea uila.I kēia mau lā, hoʻohana ʻia nā kaʻa brushed a me ka brushless ma ka honua no nā noi he nui.

Hoʻohālikelike Mechanical

He kaʻa kaʻa palakike hana nei me ka hoʻohana ʻana i nā pulupulu kalapona e pili ana me ka commutator e hoʻololi i ka uila uila i ka rotor, aia nā electromagnets.Hoʻopuka ka volta i kahi kahua electromagnetic i loko o ka rotor, ka hopena o ka neʻe ʻana i ka neʻe ʻana ma muli o ka hoʻohuli mau ʻana i ka polarity o ka huki magnetic.

Eia nō naʻe, maʻalahi ka hale, akā aia kekahi mau hemahema:

1. Ke ola palena ʻole: ʻOi aku ka pōkole o ke ola ʻana o nā mīkini palaki ma muli o ka ʻaʻahu a me ka waimaka o nā pulupulu a me ka commutator.

2 Haʻahaʻa haʻahaʻa: He haʻahaʻa ka maikaʻi o nā mīkini palaki i hoʻohālikelike ʻia me nā kaʻa brushless.ʻO ka pulupulu a me ka commutator ke kumu o ka nalowale o ka ikehu a me ka pau ʻana o ka uila, ka hopena o ka hoʻonui ʻana i ka wela.

3. Nā palena wikiwiki: Ma muli o ke ʻano kino o nā pulupulu a me nā commutators, ua palena nā mīkini palaki i nā noi kiʻekiʻe.ʻO ke kuʻi ʻana ma waena o nā pulupulu a me ka commutator kaohi i ka hiki ke kiʻekiʻe kiʻekiʻe o ka wikiwiki o nā mīkini palaki, e kaupalena ana i kā lākou hoʻohana a me ka hana i kekahi mau noi.

He kaʻa pahi ʻole heuila uila uilae hana ana me ka hoʻohana ʻole ʻana i nā pulupulu a me kahi commutator.Akā, hilinaʻi ia i nā mea hoʻokele uila a me nā mea ʻike e hoʻoponopono pololei i ka mana i hoʻouna ʻia i nā wili o ka kaʻa.

Aia kekahi mau hemahema o ka hoʻolālā brushless:

1. ʻOi aku ke kumu kūʻai: ʻoi aku ka maikaʻi o nā mīkini Brushless ma mua o nā mīkini palaki ma muli o kā lākou hoʻolālā paʻakikī a me ka ʻōnaehana hoʻokele.

2. Paʻakiki uila: Hoʻokomo ʻia nā ʻōnaehana uila paʻakikī i nā mīkini Brushless e koi ana i ka ʻike kūikawā no ka hoʻoponopono ʻana a me ka mālama ʻana.

3. ʻO ka torque liʻiliʻi ma nā māmā haʻahaʻa: Hiki ke loaʻa i nā motika Brushless ka haʻahaʻa haʻahaʻa i hoʻohālikelike ʻia me nā motika brushed.Hiki i kēia ke kaupalena i ko lākou kūpono no kekahi mau noi e koi ana i kahi kiʻekiʻe o ka torque ma nā wikiwiki haʻahaʻa.

ʻO wai ka mea ʻoi aku ka maikaʻi: Brushed a i ʻole Brushless?

Loaʻa nā pōmaikaʻi o nā hoʻolālā kaʻa brushed a me ka brushless.ʻO nā kaʻa kaʻa palaki ʻoi aku ka uku ma muli o kā lākou hana nui.

Ma waho aʻe o ke kumukūʻai, loaʻa i nā mīkini brushed ko lākou pono ponoʻī e pono e noʻonoʻo:

1. ʻO ka maʻalahi: He hoʻolālā maʻalahi nā mīkini palaki, e maʻalahi iā lākou e hoʻomaopopo a hana pū me.Hiki i kēia maʻalahi ke maʻalahi iā lākou e hoʻoponopono inā loaʻa kekahi pilikia.

2. Loaʻa ākea: Ua lōʻihi nā mīkini palaki a loaʻa nui i ka mākeke.'O ia ho'i, 'oi aku ka ma'alahi o ka loa'a 'ana o nā mea ho'ololi a i 'ole 'āpana 'āpana no ka ho'oponopono 'ana.

3. Ka hoʻomalu māmā māmā: Loaʻa i nā motika brushed kahi hana hoʻomalu maʻalahi e hiki ai ke hoʻomalu māmā.ʻO ka hoʻoponopono ʻana i ka volta a i ʻole ka hoʻohana ʻana i nā uila uila maʻalahi hiki ke hoʻololi i ka wikiwiki o ke kaʻa.

Ma na hihia e pono ai ka mana nui, a mīkini palaki ʻole hiki ke hōʻoia ʻo ia ke koho maikaʻi loa no kāu noi.

ʻO nā mea maikaʻi o ka brushless:

1. ʻOi aku ka maikaʻi: ʻAʻohe commutators nā kaʻa Brushless i hiki ke hoʻoulu i ka friction a me ka nalowale o ka ikehu, e hopena i ka hoʻololi ʻana o ka ikehu a emi ʻole ka wela.

2. ʻOi aku ka lōʻihi o ke ola ʻana: No ka mea, ʻaʻohe pulupulu i nā kaʻa Brushless e luhi i ka wā e hoʻonui ai i ka lōʻihi a me ka lōʻihi.

3. ʻOi aku ka nui o ka mana-a-kaumaha lākiō: He kiʻekiʻe ka mana o nā motika Brushless.ʻO ia ka mea hiki iā lākou ke hāʻawi i ka mana hou aku no ko lākou nui a me ke kaumaha.

4. ʻO ka hana mālie: ʻAʻole hana nā kaʻa Brushless i ke kiʻekiʻe o ka walaʻau uila a me nā haʻalulu mechanical.He mea kūpono kēia no nā noi e koi ana i nā haʻahaʻa haʻahaʻa haʻahaʻa, e like me nā mea lapaʻau a i ʻole nā ​​​​mea hoʻopaʻa leo.
