The invention discloses a fan disc for a washing machine motor and a pulsator washing machine with the fan disc. The fan disc comprises a disc plate and a plurality of blades. The disc plate is provided with a shaft hole for installing a motor shaft, a disc shaft for installing a belt and a plurality of first notches and second notches. The area of the first notches is smaller than that of the second notches. The edge of each first notch is formed into an arc shape protruding towards the center of the disc plate. The edge of each second notch is formed into a U shape with an opening away from the disc plate, and the bottom edge of the U shape extends in the circumferential direction of the disc plate. The blades are arranged on the upper surface of the disc plate at intervals in the circumferential direction of the disc plate. The first notches and the second notches are alternately distributed in the circumferential direction of the disc plate, and each blade is arranged between the corresponding adjacent first notch and the corresponding adjacent second notch. According to the fan disc, the volume of air blown to the surface of the motor can be increased, the cooling effect of the washing machine motor is improved, the number of the blades does not need to be increased, material consumption is low, and cost is low.
