A rotor structure of a magnet motor includes a rotating shaft and an iron core on the rotating shaft. Magnet grooves are disposed inside the iron core along a circumferential direction with a magnet provided therein. A distance between an edge line of the magnet groove close to a circumferential edge of the iron core and the circumferential edge of the iron core varies so that a width of a flux barrier formed varies. One end of a long side of the magnet groove close to the circumferential edge is formed with an anti-demagnetization groove communicating with the magnet groove, and an edge line of the anti-demagnetization groove tilts toward the circumferential edge of the iron core. Process slots are provided between the magnet grooves and the circumferential edge of the iron core that are used to increase a salient rate and reluctance torque of the motor.
