Title:
A MAGNETIC BEARING ASSEMBLY USING REPULSIVE MAGNETIC FORCES
Document Type and Number:
WIPO Patent Application WO2006074070
Kind Code:
A3
Abstract:
A magnetic bearing assembly utilizes repulsive magnetic forces between components, having magnetic sources, of the bearing at two or more gaps which are angled with respect to an axis of the inner component. Each gap provides force vectors in two directions, while allowing for relative movement of the components in a third direction. The gaps collectively provide a stable equilibrium in the first two directions, meaning that, in response to relative movement of the components in the first or second direction causing a decreased gap width, magnetic repulsive forces at the decreased gap width urge the components away from each other to return to equilibrium. The components of a radial magnetic bearing according to the invention move relative to one another rotationally, and the components of a linear magnetic bearing according to the invention move relative to one another longitudinally.
