Abstract:
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:
