Patent ID: 7586217

Claim:
A magnet assembly for a motor, comprising: means for assembling of a plurality of magnets associated with a magnetically conductive annular ring having a cross-sectional dimension defined by an outer perimeter relating to an exterior surface and an inner perimeter relating to an interior surface, the magnets are placed in a spaced apart relationship on top of and facing radially outward from the interior surface; and means for distributing the magnets to substantially conform to magnetic flux that travels through the magnetically conductive annular ring when the magnet is exposed to a magnetic field, such that the cross-sectional dimension of the annular ring varies according to the placement of the magnets and the non-planar topology of the exterior surface the annular ring has an exterior surface topology of peaks and valleys that are at least one of generally sinusoidal, square, triangular, and saw-toothed in shape.
