Synopsis:

Electric machines play an important role in a number of areas, such as e-mobility, renewable energy sources utilization, robotics and automation. The main objective of the course is to provide the students with deep understanding of the principles, operation, and analysis of rotating electric machinery. Mathematical models based on the theory of space phasors or FEM will be developed for various types of electric machines (induction machines, electrically excited synchronous machines, permanent magnet synchronous machines). Thorough understanding of electrical machine theory on such a level is necessary, for instance, for design of modern control methods of electric drives or construction of electric machines.

Requirements:

The presentation of transient effect calculations on the own model of DC drive and the drive with Y-D start of an induction motor.
