ROTATION-SPEED-INDEPENDENT STABILIZER FOR PASSIVE MAGNETIC BEARING SYSTEMS

摘要

By employing a combination of magnetic forces and those from electrostatic fields, a new stabilizer is able, unlike those employing dynamic effects, to function at any speed with no need for sensors or dynamically generated electrical currents. Embodiments are provided that stabilize the radial, axial and tilt instability. In addition to its use for stabilization, the radial stabilizer described herein also functions as an eccentricity detector.

1. An apparatus, comprising:
a rotatable cylinder having a central longitudinal axis; means for utilizing static electrostatic forces to stabilize at least one instability of said cylinder, wherein said at least one instability is selected from the group consisting of radial, axial and tilt; and means for utilizing magnetic forces between permanent magnets to stabilize any instability of said group that is not stabilized by said static electrostatic forces.
