Abstract

A journal bearing provides vertical and radial stability to a rotor of a passive magnetic bearing system when the rotor is not rotating and when it is rotating. In the passive magnetic bearing system, the rotor has a vertical axis of rotation. Without the journal bearing, the rotor is vertically and radially unstable when stationary, and is vertically stable and radially unstable when rotating.

Passive magnetic bearing elements and configurations utilizing alternative polarization and Amperian current direction

Patent Post, Richard F.

A ferromagnetic shield in contact with a magnet bar at the opposite end from the working surfaces of the bar eliminates the field canceling effects that arise from the Amperian currents at that end. The optimum polarization direction for such bars is one that is parallel to the azimuthal coordinate of the bar. The field at the working surface of the bar approaches that of a bar of infinite length because the shield, located on the side opposite to that of the working surface, completely eliminates, or at least substantially reduces, the field cancellation effect that normally would occur.

Halbach-array levitating passive magnetic bearing configuration

Patent Post, Richard F.

Novel configurations of levitating passive magnetic bearing configurations are described. Such configurations can be used for the precise control of the magnitude and sign of the bearing stiffness, thereby facilitating the overall design of the system in ways that are not possible with conventional attractive or repelling bearing elements.

Passive magnetic bearing systems stabilizer/bearing utilizing time-averaging of a periodic magnetic field

Patent Post, Richard F.

A high-stiffness stabilizer/bearings for passive magnetic bearing systems is provide where the key to its operation resides in the fact that when the frequency of variation of the repelling forces of the periodic magnet array is large compared to the reciprocal of the growth time of the unstable motion, the rotating system will feel only the time-averaged value of the force. When the time-averaged value of the force is radially repelling by the choice of the geometry of the periodic magnet array, the Earnshaw-related unstable hit motion that would occur at zero rotational speed is suppressed when the system ismore » rotating at operating speeds.« less

Non-contacting "snubber bearing" for passive magnetic bearing systems

Patent Post, Richard F

A new non-contacting magnetic "snubber" bearing is provided for application to rotating systems such as vehicular electromechanical battery systems subject to frequent accelerations. The design is such that in the equilibrium position the drag force of the snubber is very small (milliwatts). However in a typical case, if the rotor is displaced by as little as 2 millimeters a large restoring force is generated without any physical contact between the stationary and rotating parts of the snubber bearing.

Combined passive magnetic bearing element and vibration damper

Patent Post, Richard F [Walnut Creek, CA]

A magnetic bearing system contains magnetic subsystems which act together to support a rotating element in a state of dynamic equilibrium and dampen transversely directed vibrations. Mechanical stabilizers are provided to hold the suspended system in equilibrium until its speed has exceeded a low critical speed where dynamic effects take over, permitting the achievement of a stable equilibrium for the rotating object. A state of stable equilibrium is achieved above a critical speed by use of a collection of passive elements using permanent magnets to provide their magnetomotive excitation. In a improvement over U.S. Pat. No. 5,495,221, a magnetic bearingmore »« less
