Abstract
One embodiment of the present invention relates to a rotor and a motor having same, the rotor comprising: a rotor core; and a plurality of magnets arranged to be spaced apart from each other on an outer circumferential surface of the rotor core, wherein the rotor core includes: a body; and protrusions protruding obliquely inward at a predetermined angle from an inner circumferential surface of the body, wherein a predetermined gap (G) is formed between the inner circumferential surface of the body and the end of each of the protrusions. Accordingly, the rotor and the motor having the same may minimize the amount of change in the outer circumferential surface of the rotor core by using the protrusions. As a result, it is possible to inhibit separation of the magnets attached to the outer circumferential surface of the rotor core.
