Paper
On the theoretical determination of the alignment sensitivity of electric and magnetic devices
Abstract
In the computer design of electric and magnetic devices, when the fields can be derived from a scalar potential satisfying the Laplace equation, integral equation methods are powerful tools, particularly in 3-d problems. A certain Fredholm integral equation of the first kind, used first to obtain the potential, may be utilized a second time with a different right-hand side to obtain directly the rate of change in potential due to a change in the position of an electrode or magnet pole-piece. The new righthand side of the integral equation is formulated in simple terms. Knowledge. of this rate of change suggests itself to two types of applications: Alignment sensitivity study and improved numerical optimization of electromagnetic devices.
