This demo illustrates the connection between KIMEME, Matlab, and a generic Windows process, in this case Infolytica Magnet. This demo optimizes the geometry and dimensions of an electric motordrive to reach minimum weight and cost. Torque and efficiency values are calculated by means of FEM analysis carried on by Infolytica Magnet. The motor geometry is defined and modified by using the Matlab API. Cost and weight are estimated using an Excel spreadsheet.
