Abstract

In an improved structure of high-frequency rotary mechanism, permanent magnets with an odd number of at least five are disposed in each pole of a motor rotor, one of the permanent magnets serves as a center, the other permanent magnets are symmetrically connected in series on two sides of the center, and adjacent ends of the permanent magnets located on two sides are made as a same magnetic pole, so that the adjacent ends are separated without directly abutting against each other by a repulsion distance under a repulsive effect of the same pole, relative positions between the adjacent permanent magnets are maintained by the repulsive effect, and structures of position limiting and support in the prior art for positioning are not required, thereby avoiding centrifugal force of high-speed rotation to act on the structures of position limiting and support, and reducing negative impact on a rotor iron core.
