Abstract
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.
