ABSTRACT:
A magnetic bearing that uses a stator element comprised of four poles, one per quadrant. These poles are separated by slots, that are occupied by coils. The poles and coils are structured such that the flux generated by the coils traverses paths in which all flux passes through gaps in two orthogonal axes. In the preferred embodiment, the poles are each formed as a separate section. Coils are then placed on the poles and the poles assembled to form the stator assembly.
