Hoʻohana nui ʻia nā motika DC i nā puka ʻakomi no ko lākou kiʻekiʻe kiʻekiʻe, mālama haʻahaʻa, a me ka wikiwiki wikiwiki. Eia nō naʻe, ʻelua mau ʻano o nā motika DC: brushless a brushed. Loaʻa iā lākou nā ʻano like ʻole a me nā mea maikaʻi e kūpono i nā noi like ʻole.
Hoʻohana nā motika DC Brushless i nā magnet mau loa e like me nā rotors a me nā kaʻa uila e like me nā commutators. ʻAʻohe o lākou pulupulu a i ʻole commutators i pau i ka hakakā. No laila, ʻoi aku ka lōʻihi o ke ola, haʻahaʻa haʻahaʻa haʻahaʻa, ʻoi aku ka wikiwiki o ka wikiwiki, ʻoi aku ka maikaʻi o ka mana torque, a ʻoi aku ka nui o ka mana ma mua o ka mīkini DC brushed. Loaʻa iā lākou ka haʻahaʻa haʻahaʻa electromagnetic interference a hiki ke hana me ka palekana i nā wahi paʻakikī.
Hoʻohana nā motika DC Brushed i nā metala a i ʻole carbon brushes a me nā mīkini commutators e hoʻololi i ke ala o kēia manawa. ʻOi aku ka maʻalahi o ka hoʻolālā, haʻahaʻa haʻahaʻa, hoʻonohonoho maʻalahi, a ʻoi aku ka nui o ka loaʻa ma mua o nā motika DC brushless. ʻOi aku ka maikaʻi o ka torque haʻahaʻa haʻahaʻa a hiki ke hoʻomaka koke me ka ʻole o ka mea hoʻoponopono.
ʻO nā mea maikaʻi o nā motika DC brushless e kūpono iā lākou no nā puka ʻakomi e koi ana i ka wikiwiki kiʻekiʻe, ka pololei kiʻekiʻe, ka haʻahaʻa haʻahaʻa, ka lōʻihi o ke ola, a me ka ikaika o ka ikehu. No ka laʻana, hiki ke hoʻohana ʻia i nā puka hoʻoheheʻe e pono e wehe a pani wikiwiki a maʻalahi. ʻO nā mea maikaʻi o nā motika DC brushed e kūpono iā lākou no nā puka ʻakomi e koi ana i ke kumu kūʻai haʻahaʻa, hoʻonohonoho maʻalahi, ka mana maʻalahi, a me ka torque hoʻomaka kiʻekiʻe. No ka laʻana, hiki ke hoʻohana ʻia i nā puka koli e pono ai ke lanakila i ka inertia a me ka friction.
