ʻO ka pahu kalapona DC motor he kaʻa DC nona ka manaʻo hana i hoʻokumu ʻia ma ka electromagnetic induction o DC. Loaʻa iā ia kahi rotor rotating a me kahi stator paʻa, e hoʻopuka ana i ka torque ma o ka electromagnetic induction e hoʻokō ai i ka neʻe mechanical. He hana hoʻomaka maikaʻi ka mīkini kalapona DC a hiki ke hāʻawi i kahi torque hoʻomaka nui i ka manawa koke. Loaʻa iā ia kahi laulā hoʻololi wikiwiki a hiki ke hoʻokō i ka wikiwiki paʻa ma lalo o nā ukana like ʻole. He mea maʻalahi ka hale, he haʻahaʻa ke kumukūʻai mālama a lōʻihi ke ola lawelawe. Hana kēia i ka XBD-3571 carbon brushed DC motors i hoʻohana nui ʻia i nā noi he nui, e like me nā laina hana ʻenehana, nā kaʻa, nā mea pono hale, etc.
