In this paper, Permanent Magnet Power Magnetic Bearing (PPMB) is analyzed and optimally designed based on finite element analysis software– ANSYS, aiming at air-gap magnetic field distribution, levitation force, output torque.

Modeling of permanent magnetic bearing library based on solidworks;

An upper permanent magnetic bearing(PMB) was designed for a high-power,high-speed vertical energy storage flywheel.

The permanent magnetic bearing has many advantages:simple structure,free-friction,low-cost etc,and it can construct many types of bearing system with the mechanical bearing or the electromagnetic bearing,having wide applications.

Research on the Radial Magnetic Force of Axial Placement and Axial Magnetization Bi-annular-shaped PMB;

Mechanical characteristics of permanent magnet bearings is expressed by bearing capacity and bearing stiffness.

This paper describes the principle and developing survey of magnetic bearings, analyzes with the emphasis being laid on the stability of radial permanent magnet bearings, and realizes the system stability by using the axial stable mechanism of the magnetic—thrust bearings with mechanical auxiliary.
