Abstract:
1. A magnetic levitation weight reduction structure for a vertical wind turbine generator, comprising: a frame; a fixed permanent magnet fixed to the frame having a first repulsive surface; an axle connected to the frame comprising a first connecting portion and a second connecting portion; a revolving permanent magnet secured to the axle having a second repulsive surface in relation to the first repulsive surface of the fixed permanent magnet, the first repulsive surface and the second repulsive surface repelling with each other, the axle functioning as a balance center when the revolving permanent magnet is rotated; a blade hub connected to the first connecting portion of the axle; a generator connected to the second connecting portion of the axle; wherein the fixed permanent magnet and the revolving permanent magnet each has at least one inclined portion, wherein the first repulsive surface and the second repulsive surface correspond to each other, to create a repulsive force so that the axle remains in a vertical position while turning without bias to exaggerate a resistance; and wherein the fixed permanent magnet and the revolving permanent magnet have a disk shape.
