Abstract :
The authors study the influence of two geometric variables, the air gap and the magnet thicknesses, by using a finite element method based package, thus avoiding the parametric representation. The fundamental component of each variable was used to determine power and speed. A sinusoidal no-load voltage as well as a sinusoidal current source justify this approach
