Abstract: An embodiment relates to a motor comprising: a shaft; a rotor engaged with the shaft; and a stator disposed outside the rotor, wherein the stator includes a stator core formed by stacking a plurality of sheets and a coil wound around the stator core, the stator core including a yoke having a hole formed therein, a tooth protruding radially from the yoke, and an adhesive member disposed in the hole, the hole being disposed on an imaginary line L extending radially along the side of the tooth. Accordingly, the motor can form a stator core by stacking sheets, and reduce noise and vibration by filling an adhesive member in a hole formed in the stator core.

Abstract: An embodiment relates to a rotor and a motor comprising same, the rotor comprising: a rotor core; and a plurality of first magnets and second magnets arranged along the outer circumferential surface of the rotor core, wherein each of the second magnets is disposed between the first magnets, and the outer circumferential surface of each of the first magnets has a curvature greater than that of the outer circumferential surface of the second magnet. Therefore, the motor can reduce cogging torque by using the first magnet and the second magnet having different shapes, and thus can improve the quality of the motor.
