Abstract
The present invention provides a stator including magnets having six poles; a rotor disposed inside the stator and including thirteen slots; a coil wound around the slot; a rotary shaft coupled to the rotor; a commutator coupled to the rotary shaft and connected to the coil; and a plurality of brushes disposed to be pressed against the commutator and located to have an angular interval of 63° to 66° in the circumferential direction of the rotary shaft, thereby providing advantageous effects in that a current ripple is minimized and a torque is maximized.
