Abstract: A rotor that may include a first rotor core, a second rotor core disposed below the first rotor core, a first insulator coupled to the first rotor core, and a second insulator coupled to the second rotor core. The first rotor core may include first teeth protruding from a first outer circumferential surface thereof, and the second rotor core may include second teeth protruding from a second outer circumferential surface thereof. The first insulator may include a body configured to surround the first teeth. A first outer guide may be formed at an outside of the body with respect to a radial direction of the first rotor core, and the second insulator may include a body configured to surround the second teeth. A second outer guide may be formed at an outside of the body with respect to a radial direction of the second rotor core. The first teeth and the second teeth may be disposed at different positions with respect to a circumferential direction. The first outer guide and the second outer guide may be configured to abut each other such that a separate member for filling a space into which a nozzle is inserted is omitted. A manufacturing time and a manufacturing process can be reduced based on such disclosure.

Abstract: In an embodiment, disclosed is a motor comprising: a stator; a rotor disposed to correspond to the stator; and a shaft coupled to the rotor, wherein the rotor comprises: a rotor core including a yoke and a plurality of rotor teeth arranged on the yoke so as to spaced apart in the circumferential direction; a plurality of magnets arranged between the rotor teeth; and a can disposed on the rotor core on which the plurality of magnets are arranged, the can includes a first can having a hole and a second can having a protruding part coupled to the hole, and the protruding part is disposed to face the outer surface of the magnet. Therefore, the motor uses the protruding part of the can so as to inhibit the separation of the magnets, inhibit the leakage of flux, and be implemented to be more compact than a conventional spoke-type motor. In addition, the motor can inhibit the leakage of magnetic flux that flows toward the shaft.
