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.

Prerequisite: Final-year standing or permission of the Department; ENGR 411 concurrently. This will be a design project carried in groups of about four students under the direct supervision of a faculty member, and will normally be carried out over two terms. General project specifications and membership of design groups will be determined by the Department in consultation with faculty members and, where feasible, with industry. Each group will choose a group leader who will be responsible for overall coordination of the project. The project will consist of three phases with deadlines for completion determined by the Department. The first phase consists of the project specification and plan of work where each member of the group will submit in writing and orally, one portion of the total specification. This will be graded for content and quality of presentation. The second phase consists of project execution. The third phase consists of the preparation and presentation of a report. Again, each member of the group is expected to prepare a portion of the final report and to present it both in writing and orally. Tutorials will consist of meetings with the supervising faculty member, as well as some instruction and exercises on verbal and oral presentations. Tutorial: one hour per week, two terms. Equivalent laboratory time: four hours per week, two terms.
Note: Students are responsible for acquiring a complete set of instructions and the document Form and Style before beginning the project.
