This course focuses on advanced modeling, design and control strategies of electrical machines. The real ABC models will be developed and motivation for a transformation made. The Park transform will be used to derive the d,q models of induction and synchronous machines. Vector control strategies will then be discussed, along with appropriate current control strategies and overall drive design concepts. The switched reluctance motor will be presented including techniques for modeling the nonlinear iron characteristics. The design of permanent magnet machines will be introduced. Eddy current loss models will also be presented. The synchronous reluctance motor will be introduced. A Design project will also be given.
