ʻO ka motika metala DC he kaʻa maʻamau e hoʻololi i kēia manawa ma o ka hoʻopili ʻana ma waena o nā pulu kalapona a me ka rotor kaʻa kaʻa. ʻO kēia hoʻolālā e hana maʻalahi ka mīkini palaki DC DC, haʻahaʻa, a maʻalahi hoʻi e kāohi. ʻO nā mīkini palaki metala DC ka mea maʻamau i ke kino kaʻa, nā pulupulu kalapona, nā mea paʻa palaki, nā mea lima, nā magnet mau a me nā mea ʻē aʻe. Hoʻohana nui ʻia ka XBD-1330 metal brush DC motors i nā mea pono hale, ʻoihana ʻenehana, ʻenehana uila a me nā kula ʻē aʻe. Ua ʻike nui ʻia lākou no ko lākou ʻano maʻalahi, ke kumukūʻai hana haʻahaʻa a me ka torque hoʻomaka nui.
