An embodiment discloses a motor comprising: a stator; a rotor disposed to correspond to the stator; and a shaft coupled to the rotor. The rotor includes a rotor core coupled to the shaft, a plurality of magnets disposed outside the rotor core, and a can disposed to cover the rotor core and the magnets. The can includes a base, a body extending from the base in the axial direction, and a plurality of extension portions extending from the end portion of the body, wherein with reference to the radial direction, the radius R2 from the center C to the extension portions is longer than the radius R1 from the center C to the body. Accordingly, the motor can induce easy insertion of the magnets by using the can having two regions having different radii, thereby simplifying a manufacturing process of the motor and improving productivity thereof.
