Hoʻohana nui ʻia nā motika DC i nā puka aunoa no ko lākou pono kiʻekiʻe, mālama haʻahaʻa, a me ka maʻalahi o ka hoʻokele wikiwiki. Eia nō naʻe, aia ʻelua ʻano o nā motika DC: brushless a brushed. Loaʻa iā lākou nā ʻano like ʻole a me nā pono 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 kaapuni uila e like me nā commutators. ʻAʻohe o lākou mau brushes a i ʻole commutators e pau i ka friction. No laila, ʻoi aku ka lōʻihi o ko lākou ola, haʻahaʻa ka pae walaʻau, ʻoi aku ka wikiwiki o ka laulā, ʻoi aku ka maikaʻi o ka kaohi torque, a ʻoi aku ka nui o ka mana ma mua o ka motika DC brushed. Loaʻa iā lākou ka haʻahaʻa o ka hoʻopilikia electromagnetic a hiki ke hana palekana i nā wahi ʻino.
Hoʻohana nā motika DC palaki i nā palaki metala a kalapona paha a me nā mea hoʻololi mechanical e hoʻololi i ke kuhikuhi o kēia manawa. Loaʻa iā lākou ke ʻano maʻalahi, ke kumukūʻai haʻahaʻa, ke kau ʻana maʻalahi, a me ka loaʻa ākea ma mua o nā motika DC brushless. Loaʻa iā lākou ka hana torque haʻahaʻa haʻahaʻa a hiki ke hoʻomaka koke me ka ʻole o kahi mea hoʻokele.
ʻO nā pono o nā motika DC brushless e kūpono iā lākou no nā puka ʻakomi e pono ai ka wikiwiki kiʻekiʻe, ka pololei kiʻekiʻe, ka walaʻau haʻahaʻa, ke ola lōʻihi, a me ka pono o ka ikehu. No ka laʻana, hiki ke hoʻohana ʻia i nā puka paheʻe e pono ai ke wehe a pani koke a me ka mālie. ʻO nā pono o nā motika DC palaki e kūpono iā lākou no nā puka ʻakomi e pono ai ke kumukūʻai haʻahaʻa, ke kau ʻana maʻalahi, ka mana maʻalahi, a me ka torque hoʻomaka kiʻekiʻe. No ka laʻana, hiki ke hoʻohana ʻia i nā puka swing e pono ai ke lanakila i ka inertia a me ka friction.
