Abstract

The subject matter described herein includes a magnetic bearing assembly and an arrangement of position sensors for the magnetic bearing assembly. In one example the magnetic bearing assembly includes a rotor for fixedly coupling to a shaft for rotating with the shaft. The assembly further includes at least one stator assembly located adjacent to the rotor and circumferentially surrounding the shaft. The stator assembly includes a control coil for magnetically supporting the rotor. The stator assembly further includes a plurality of position sensors that are circumferentially spaced from each other and that extend radially from the stator assembly for measuring an indication of axial displacement of the rotor.
