Patent ID: 10594178

Abstract:
Disclosed are a rotor that is capable of more efficiently using magnetic flux from magnets and a motor including the same. The rotor includes a plurality of rotor cores, a plurality of magnets magnetized such that magnetic flux is formed in the circumferential direction, the magnets and the rotor cores being alternately arranged in the circumferential direction, a coupler connected to a shaft, and a rotor frame formed by injection molding, the rotor frame being integrally coupled to the rotor cores, the magnets, and the coupler, wherein each of the rotor cores includes a pole shoe for defining a gap between each of the rotor cores and a stator and a rotor core body having a depression formed in the side opposite to the pole shoe in the radial direction, and portions of side surfaces of corresponding ones of the magnets located at opposite sides of each of the rotor cores are exposed by the depression to define an aperture formed in the circumferential direction.
