Contenido del curso

The course covers the construction, operating principles, and performance characteristics of electrical machines. It introduces synchronous and induction machines as well as brushed and brushless DC machines, with emphasis on their characteristics and typical application areas. Further topics include the variable-speed operation of electrical machines using power electronic converters, their topology and operating principles, and the mathematical modelling of electrical machines based on space vector theory.

Building on these foundations, the course presents the control structures of modern electric drive systems, including field-oriented control. In addition, students learn methods for sizing electric drives based on load profiles and electromagnetic and thermal design constraints. The course also addresses inverter-induced bearing currents, their physical mechanisms, and appropriate mitigation techniques.

By combining fundamental theory with engineering applications, the course provides students with the essential methods for analysing, designing, sizing, and evaluating modern electric drive systems.
