  • To overcome the defects of the present permanent magnet biased axial radial magnetic bearing, a new permanent magnet biased axial radial magnetic bearing (PARMB) was studied, which was used in magnetic suspending switched reluctance motor application. The configuration and fundamental principle of PARMB were analyzed. The equivalent magnetic circuit was established to deduce the mathematical models of PARMB. The parameter design and calculation were presented. The parameters of the proposed prototype were also given. The 3-D magnetic field simulation was performed by using the finite element software. The theory analysis and the simulation show that the presented PARMB has smaller volume compared to the existed structure, here is no coupling between axial and radial directions, the control is easier than before. Therefore, the proposed PARMB is more suitable for the high speed or low loss occasions.
