Space Mapping-Based Fractional Horsepower Permanent Magnet Motor Design

As for highly integrated fractional horsepower motors, designing the drives of interest requires the use of numerical tools, e.g., 3D finite element models which, however, entail undesirable lengthy design times. The well-known space mapping approach, which takes advantage of using both a coarse and a fine model for the optimization and design processes, is used to reduce the design time, while allowing for overall reasonable accuracy. Compared to a design approach solely with 3D finite element analysis (FEA), the space mapping technique is predicted to enable the possibility of a multi-physics optimization of a drive in a one day run. While established as a recognized technique, space mapping has not yet found its application in the design of fractional horsepower machines.
