Learning outcomes:
This module prepares students specializing in power engineering for the study of electrical machines and drives and provides students taking other specialist courses with an overview of the most important concepts and relationships underlying conventional electrical machines.
After completing this module, students will have a solid understanding of the fundamental concepts of electromechanical energy converters, and in particular the steady-state performance characteristics of synchronous, induction and DC machines. They will be able to develop solutions to simple problems in the field of electrical machines.
