Disclosed herein are apparatuses having a stator and a rotor configured to provide both a magnetic drive means and a magnetic bearing means for a rotatable element. The stator and rotor are configured to operate in unison to provide a magnetic force to rotate a rotatable element associated with the rotor about an axis and to control a radial, an axial, and a tilt position of the rotatable element about the axis. The rotor and stator assemblies are configured with complementary surface shapes to produce shapeable magnetic drive forces and shapeable magnetic bearing forces to drive and control an axial, a radial, and a tilt position of an associated rotatable element.
