Abstract

The invention discloses a double-circular table magnetic bearing rotor. The double-circular table magnetic bearing rotor comprises a rotor body, and different from the prior art, the rotor body is characterized in that the bottom surfaces of two same circular tables are connected in an overlapping manner to form a double-circular table structure, an included angle between slope buses and axes of the two circular tables is alpha, and alpha is larger than or equal to 15 degrees and is smaller than or equal to 45 degrees. According to the magnetic bearing rotor, the double-circular table structure is adopted, so that radial bearing force is greatly improved, and axial and radial coupling interference is reduced.

Description

technical field [0001] The invention relates to a magnetic force bearing component, in particular to a double circular table magnetic force bearing rotor. Background technique [0002] Magnetic bearing is a device that uses the current in the electromagnet coil to generate a non-contact controllable electromagnetic force to make the rotor run in a stable and suspended state in space. The emergence and application of magnetic bearings have broken many traditional concepts and led to a revolution in support technology. [0003] The rotor of the magnetic bearing is its rotating part, and it is used to realize the conversion device of electrical energy and mechanical energy and mechanical energy and electrical energy. The rotors of existing magnetic bearings are mostly cylindrical structures, which more or less have the problems of low radial bearing capacity and obvious coupling interference between axial and radial directions. Contents of the invention [0004] The purpose...
