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.

Structure of high-frequency rotary mechanism

A high-frequency rotating structure provided by the invention has an annular rotating element with a quincuncial outer periphery, a plurality of radially arranged accommodating grooves respectively disposed in an annular body of the rotating element, a plurality of hole-shaped magnetic barrier spaces respectively disposed in the annular body, and respectively communicated with one of two ends of each of the accommodating grooves, and a plurality of magnetic assemblies respectively embedded in each of the accommodating grooves. A shortest first distance A between a groove wall of each of the two ends of each of the accommodating grooves and an outer annular surface of the body, and a shortest second distance B between a hole wall of each of the magnetic barrier spaces and the outer annular surface of the body are defined by the following formula 1:
