Abstract
Modeling in the air gap of electric machines is often challenging. The air gap length may be several orders of magnitude smaller than the circumference. Thus, air gaps in general have poor aspect ratios. Since several layers of elements may be required to obtain a good field solution, we may have to compromise between poorly shaped elements or a very large number of unknowns. Moreover, for the moving grid methods described in Chapter 9, the finite elements in the air gap become distorted during the calculation. Re-meshing the air gap to eliminate the distortion introduces additional complication and inconvenience.
