Abstract

The invention discloses a rotor, a motor, a compressor and a refrigerator. The rotor comprises a rotor iron core and a plurality of magnets, wherein a plurality of mounting grooves, which are uniformly formed at intervals in a circumferential direction, are formed in the rotor iron core; each mounting groove runs through the rotor iron core in the axial direction of the rotor iron core; the multiple magnets are in one-to-one correspondence to the multiple mounting grooves; each magnet is accommodated in the corresponding mounting groove; each magnet is indented in a direction towards the central axis of the rotor iron core to configure the magnet into a circular arc shape, wherein the maximum outline radius of the rotor iron core is R1; the radius of a circle of a circular arc surface on one side, far from the central axis of the rotor iron core, of each magnet is R2; the thickness of each magnet is H, and R, R2 and H satisfy a condition that R2 / R1 is greater than or equal to 0.84 and less than or equal to 0.88; H / R1 is greater than or equal to 0.22 and less than or equal to 0.245. According to the rotor disclosed by the invention, processing of the magnets is simplified, the material utilization rate of the magnet is improved, and the magnets are high in demagnetization resistance.
