摘要： A turbomachine includes a housing and a rotatable shaft, where at least a portion of the rotatable shaft is located in the housing. The turbomachine also includes a magnetic thrust bearing that axially positions the rotatable shaft and a radial bearing that centers the rotatable shaft. The turbomachine includes a flexure including a first portion secured to the housing and a second portion axially moveable relative to the first portion. The second portion of the flexure is connected to the radial bearing, and the second portion moves axially to eliminate thrust loads on the radial bearing and allow the magnetic thrust bearing to carry axial loads.

摘要： A specific force capacity thrust bearing and a method for producing such a design for a particular application are disclosed. The magnetic flux density in the stator material is maximized by varying cross-sectional area normal to the flux path. After a set of initial parameters are chosen, the design can be improved upon by changing the design variables and then verifying the force capacity using a finite element program. By linking the finite element program to a model of the geometry and using some basic algorithms, it is possible to automatically iterate until an optimal design is reached. The resulting design has a much higher force capacity than designs typical of the prior art.

摘要： A flywheel levitation apparatus and associated method are described for use in a flywheel driven power storage system having a rotor and which provides for an upward vertical movement of the rotor along an axis of rotation. The rotor includes a rotor face defining a cutaway section. A magnetic lifting force is applied to the rotor to at least in part serve in levitating the rotor. The magnetic lifting force exhibits a modified gap sensitivity that is smaller as compared to a conventional gap sensitivity that would be exhibited in an absence of the cutaway section.

摘要： A turbomachine includes a housing and a shaft mounted rotatably relative to the housing about a rotary axis, an element with a through opening through which the shaft protrudes, a first ring element and a second ring element. The first ring element is arranged with its inner surface on the shaft and the element is fixed by the first ring element at a predetermined position on the shaft. The second ring element is arranged with its inner surface lying on the outer surface of the first ring element, which outer surface tapers conically from a first axial end to a second axially opposite axial end. The inner surface of the second ring element tapers conically in a complementary way to the outer surface of the first ring element. An axial movement of the second ring element relative to the first ring element compresses the first ring element against the shaft.
