Electromagnetic modeling of machines

This course aims to provide the necessary understanding to develop basic models of rotating electrical machines. The various models obtained are used to describe the behaviour ‘as seen from the terminals’, with a view to simulating them using equivalent circuit diagrams or controlling them.
By listing the various simplifying assumptions for linear modelling, learners will become familiar with key concepts such as periodicity, the concepts of smooth or salient poles, magnetic saturation and slot effects – all distinguishing characteristics that have a significant impact on the performance and accuracy of the models.

By the end of the course, students will be able to:
1.    Distinguish between the different classes of rotating magnetic machines: synchronous and asynchronous machines, and machines with smooth poles and salient poles
2.    Apply modelling methods aimed at ultimately obtaining a simple steady-state or transient model (Behn-Eschenburg model, Blondel diagram, Steinmetz model, etc.)
3.    Establish the basic analytical relationships to define a control model (Park, Clarke and Concordia transforms)
4.    Calculate steady-state operating points, define the machine’s operating regions in the torque-speed plane, and calculate short-circuit currents and efficiency
