Description
Summary:Passive magnetic bearing with Halbach array method used for combining the direction of magnetization of the permanent magnets, may alleviate some critical aspects related to the usage of the conventional bearing solutions for high-speed electromechanical systems. This paper presents numerical simulation results of such a passive magnetic bearing (PMB) concerning the static loads, and some critical problems related to the limitation of the conventional bearing solutions. The magnetic flux and the magnetic forces occurring in the magnetic bearing air gap, and the radial loads are evaluated. The rotor is subjected to static displacements to determine the radial and axial magnetic forces that occur between the rotor and stator parts.
