Summary:The invention discloses a blade overflow hole of a magnetic suspension savonius rotor wind driven generator. The blade overflow hole comprises a rotary shaft, overflow holes, blades and a base disk, wherein the rotary shaft penetrates through the base disk and is fixed on the base disk; the blades are uniformly arranged on the rotary shaft along the circumference; the side face of each blade is fixed on the rotary shaft, the bottom of each blade is fixed on the base disk; and the part, adjacent to the shaft, of the root of each blade is axially provided with a plurality of overflow holes. According to the invention, because the curvature of each blade decreases gradually from the axis center to the outward, the wind utilization ratio is increased, the assistance to the next blade by the utilized wind can be increased due to the overflows on the blades, blade resistance is reduced, and the secondary utilization process of the utilized wind is increased, so that the efficiency of the wind driven generator is im
