Rotational apparatus
First Claim
1. A fluid movement apparatus comprising, a housing having a circular cross-section, an inner passage having a longitudinal axis, a first portion adapted as an inlet to receive a fluid, and a second portion adapted as an outlet to provide an egress for the fluid;
- an impeller disposed in the inner passage having a plurality of blades radially extending from a center portion of the impeller, and an impeller drive assembly having a stator configured to generate a shapeable magnetic field to drive the impeller in an axial rotation about the longitudinal axis of the housing and to control a radial position and an axial position of the impeller in the inner passage of the housing.

Abstract
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.
