Abstract
Provided are a rotor including a demagnetization prevention barrier for preventing the demagnetization of a permanent magnet which is buried along the circumference, a motor including the rotor, and a method of manufacturing the rotor, the rotor including a rotor core provided to be rotatable by attraction and repulsion applied from an outside, a plurality of permanent magnets buried along a circumference of the rotor core to extend in a different direction from a radial direction of the rotor core, and a plurality of demagnetization prevention barriers installed to be spaced apart from both ends of each of the plurality of permanent magnets in an outer circumferential surface direction of the rotor core so that a magnetic flux that causes demagnetization to the plurality of permanent magnets is blocked.
