The embodiment of the invention provides a rotor, a motor and an electrical product. The rotor comprises a rotor core and a plurality of magnetic flux barriers, in a plane perpendicular to the axial direction, the whole of at least two magnetic flux barriers corresponding to all poles of the rotoris located inside a spread angle, the size of the spread angle is determined according to the number of poles of the rotor and the number of phases of the motor, the center line of the spread angle is the q-axis of the rotor, and the ratio of the area of the magnetic flux barriers which are integrally positioned in the spread angle to the area of all the magnetic flux barriers corresponding to the poles is greater than or equal to 1/2; and the ratio of the difference between the area of the magnetic flux barrier located in the innermost side in the radial direction inside the spread angle and the area of the magnetic flux barrier located in the outermost side in the radial direction inside the spread angle to the sma
