Abstract
The numerical tools required by the transient modeling of electrical machines are reviewed from an energetic viewpoint. The consistency with the finite element method is given. The impact of these modeling requirements is inspected on a high-sensitivity relay case-study and attention on motion-induced eddy currents is given. Due to the trend in energy savings expected in many markets, it is emphasized that future numerical software should take properly into account the loss processes within a 3-dimensional description.
