Objectives
Objectives
Since some of the necessary analysis tools, such as the transformer and the DC machine, have been introduced already in Electrical Machines I, the focus of study is now set on the asynchronous machine, synchronous machine and some special electric machines. It is intended to provide students with analytical skills and tools for the design of electrical machines (EM), developing their ability to understand the operating principles inherent to each machine, as well as their applicability in practical problems. Simultaneously, it is intended that students be able to increase their critical mind-set in the analysis of results, promoting the experimental evidence of the concepts taught through laboratory tests and the performance of simulation works, using models developed by the students.
